An Experimental Investigation on Treatment of Tannery Effluent Using Azadirac...IJEAB
A preliminary investigation was carried out for the feasibile use of Azadirachta indica leafs powder as a natural coagulant to the treatment of tannery effluent. In this paper, Azadirachta indica leafs powder of 1, 2, 3 and 4mg/L dosages were used. Floc formation in coagulation process had been studied in the laboratory scale to determine the optimum dosage of natural coagulant. The above dosages were used in pre-treated tannery effluent with coagulants were considered to evaluate the percentage removal efficiency on the major pollutants of concern in in tannery effluent such as turbidity, TSS, TDS, COD and BOD. From the observed results, dosage of 3 mg/L gives better removal efficiencies with respect to turbidity, TSS, TDS, COD and BOD and appears to be suitable for tannery effluent treatment, when compared with other dosages.

Effect of temperature on biodegradation of textile dyeing effluent using pilo...Agriculture Journal IJOEAR
Abstract— This study deals with the effect of temperature on treatment of real textile dyeing effluent using pilot scale two-phase Upflow Anaerobic Sludge Blanket (UASB) reactor with sago effluent as co-substrate under recycle mode. The temperature of the reactor was varied viz. 35, 40, 45 and 50 0C. The feed of the reactor was 30% of methanogenic outlet recycled and 70% of 70/30 (sago/textile dyeing effluent) mixing ratio were given at the bottom of the reactor. The reactor was operated at 24 h of HRT. The performance of the bioreactor was evaluated by monitoring the removal of Chemical Oxygen Demand (COD), removal of color, Volatile Fatty Acid (VFA) and biogas production. The overall COD and color removal were achieved maximum of 98.4% and 99.3% respectively. Based on temperature, the biogas production (0.512 m3/d) was maximum at 450C. From the VFA and alkalinity ratio values obtained indicate that the reactors were operated under steady state. The results shows, that the sago and textile dyeing effluent have wide variation in their characteristics were treated on combination, whereas the recycle ratios maintain the stability of reactor. This new technology supports the effective utilization of sago effluent in destruction of dyeing effluent; the optimum temperature for efficient reactor operation was 450C.
Abstract— Field experiments were conducted during kharif 2014 and 2015 with curry leaf variety Suwasini to study the dissipation pattern of carbendazim 50 EC at 500 g a.i. ha-1 and cypermethrin 10 % EC @ 50 g a i/ha (550 ml/ha) 1 by giving two sprays first at vegetative stage and second 10 days later. The leaf samples collected at 0, 1, 3, 5, 7, 10, 15, 20, 25, 30 and 45th day after second spray and soil samples at 45th day for residue analysis showed initial deposits of carbendazim 16.00 mg kg-1 and Cypermetrin 13.09 mg kg-1 which ,dissipated to 0.04 mg kg -1 and 0. 28 mg kg – 1 respectively. The residues reached to Below Determination Level (BDL) at 20 and 10 days, respectively. As there were no pesticide recommendations and MRLs fixed for any of the pesticide in curry leaf, the day at which residues reached BDL can be suggested as the safe harvest period for curry leaf.

Application of response surface methodology for biosorption of reactive dyes ...IJLT EMAS
Response Surface Methodology was employed for
studying the biosorption of reactive dyes from textile effluent by
utilization of dead biomass of Rhizopus arrhizus in a batch
system. Central Composite Design at the specified combinations
of four variables (pH, biosorbent dosage, speed of agitation,
contact time) was adopted to achieve maximum biosorption. The
fitted quadratic model (P<0.0001) was used to arrive at the best
operating conditions. Under the following optimum conditions
i.e., pH 2.0; biosorbent dosage 3 g /L; speed of agitation 80 rpm
and contact time 60 min, 99.60% of the dyes were removed from
the wastewater. The mechanism of biosorption was elucidated by
FTIR, XRD and BET analysis. This work demonstrated the
feasibility of employing Rhizopus arrhizus as an effective and
economical fungal biosorbent for the removal of dyes from the
textile effluent.

Investigation of removal of methylene blue by nitrated biomass of Cicer arientinum is conducted in batch conditions. The effect of different parameters such as contact time, sorbent dose, pH and temperature has been studied. Adsorption kinetic modeling data were found out. The kinetics of biosorption results shows that sorption process is well explained by pseudo–second order model with determination coefficients higher than 0.99 for sorbent under all experimental conditions. The value Kp is found to be 0.652 to 2.43 for initial and final concentrations. Thermodynamic parameter via KD, ΔG has also been calculated to determine the spontaneity of the process. The low value of activation energy indicates that sorption is an activated and physical process. The Weber and Morris intraparticle diffusion model show liquid-film, mass transfer is effective sorption mechanism. Thus nitrated biomass of Cicer areintinum is a low cost and easily available efficiently used as an excellent sorbent for the removal of MB+ from wastewater. It can be safely concluded that biomass of Cicer arientinum is much economical effectual, viable and can be an alternative to more costly adsorbents.

Simultaneous nitrification and denitrification (SND) bacteria can complete nitrification and denitrification processes under aerobic conditions simultaneously, which has some obvious advantages in comparison with traditional method for nitrogen removal, such as reducing energy consumption and construction cost. Three SND bacteria strains, YX3, YX4 and YX6 were isolated from a polluted river and identified as Pseudomonas spp. by phylogenetic analysis based on 16S rDNA sequencing. After cultivated in liquid heterotrophic ammoniation medium at 30°C by shaking at 150 rpm for 3 d, the NH4+-N removal rates of strains YX3,YX4 and YX6 were 93.50%, 91.50% and 91.00%, respectively; and the total nitrogen removal rates of YX3, YX4 and YX6 were reached 85.75%, 87.33% and 90.46%, respectively. The NO3--N removal rates of strains YX3, YX4 and YX6 were 87.24%, 89.88% and 88.73%, respectively, after cultivated in liquid denitrification medium at 30°C by shaking at 150 rpm for 3 d. These results show that all these strains were capable of simultaneous nitrification and denitrification. When strains YX3, YX4 and YX6 were faced to high ammonia pharmaceutical wastewater, NH4+-N concentrations decreased from 500±78.47 to 238.14±63.77mg/L, 155.82±79.95 mg/L and 214.62±92.69 mg/L, respectively, after cultured at 150 rpm and 30°C for 3 d. After four months of acclimation, the NH4+-N remove rates were improved significantly under the same culture conditions and the NH4+-N concentrations decreased linearly from 500±81.79 to 151.9±88.70mg/L, 94.73±58.66 mg/L and 114.49±56.84 mg/L of strains YX3, YX4 and YX6, respectively. All the strains showed rather steady features in bio-denitrification of high ammonia pharmaceutical wastewater after acclimation under laboratory conditions. This suggests that all the three strains have great application potential in high ammonia nitrogen pharmaceutical wastewater treatment.
Tea (Camellia sinensis) Waste for the reduction of Malathion and Phorate in ...Agriculture Journal IJOEAR
Abstract— Diminution of Malathion and Phorate from aqueous solutions by tea waste biomass was examined in a batch experimental setup. Waste tea powder, obtained from University canteen, S.V. University, Tirupati, India has been used as an effective material for the reduction of Malathion and Phorate from aqueous solutions. Characterization of the adsorbent was studied using SEM micrograph and Fourier Transform Infrared spectral analysis. From the FTIR spectrum it is observed that the change in peak position at 3390 cm−1 in the spectrum of the Phorate and Malathion loaded tea powder indicates the binding of these pesticides with hydroxyl groups. The working solutions of the pesticides are in the range of 0.1µg – 1.0µg for Malathion and 0.05µg – 0.5µg for phorate. It was observed that percentage adsorption increased with pH of the liquid phase and reached an optimum value of 95 % for Malathion and 94 % for phorate at pH 7.4 ± 0.2 and pH 7.5 ± 0.2, respectively. The dosage of the adsorbent had showed considerable effect on the adsorption of Malathion and Phorate.

The Use of Moringa Oleifera Seed As A Coagulant For Domestic Water Purificationiosrjce
The efficiency of Moringa Oleifera seed powder as a coagulant for domestic water purification was
investigated using the Jar Test.The optimum dosage of moringa oleifera seed powder was observed to be at
90mg/L. The results of the physiochemical parameters tested at the point of sample collection and at 90mg/L
optimal dosage respectively are as follows: pH (8.1 and 7.9) temperature (26.6oC and 26.8oC), conductivity
(1.75 µs/cm and 1.78 µs/cm), dissolved oxygen (0.30mg/l and 0.10mg/l), turbidity (339 and 4.10NTU), and
hardness (212mg/l and 300mg/l) respectively. Analysis of some metals such as copper, chromium, lead, calcium,
magnesium, cobalt and zinc were performed before and after treatment of the water sample with the Moringa
oleifera seed. The metals analyzed (Cu, Zn, Ca, Cr, Pb, Co, and Mg) before and after coagulation showed that
concentration of Zn, Cu, Co, Pb and Ca as increased in the most optimally purified water containing 90mg/L
Moringa Oleifera seed Powder from, 1.12 to 2.54mg/L, 0.18 to 0.39mg/L, 0.00 to0.19mg/L, 0.00 to 0.08mg/L
and 1.02 to 2.10 mg/L respectively. And magnesium concentration decreased from 36.32 to 27.89 mg/L.

Turbidity is one of the major culprits which help microbes present in water and waste water to survive. Also
drastically impact the water treatment efficiency mainly the process of disinfection. Coagulants such as Alum, PAC (Poly Aluminium Chloride), FeCl3 etc, are majorly used for the turbidity removal in water. Among this Alum is the most widely used coagulant in water treatment, because of its proven performance and cost effectiveness. Although alum has a proven track record,
usage of same in drinking water system increases the concentration of Aluminium ion which does not falls under the WHO (World Health Organization) norms of drinking water standards. Hence this study would be an alternate approach for turbidity
reduction in water by using natural coagulants. Different studies in ancient Tamil Literature show Strychnos potatorum Linn or
Nirmali seed act as a best coagulating agent, which in turn helps in removal of turbidity in water. This study was done to evaluate the effectiveness of Strychnos potatorum Linn seed extract in removal of turbidity from the selected water samples. An existing
water softener system of capacity 2 m3
/hr from a Residential Apartment named M/s.Ozone Pavillion was selected with an existing scheme of Alum dosing system, Pressure sand filter, Activated Carbon filter and Softener. In this scheme the Alum dosing was replaced with Strychnos potatorum Linn seed extract dosing and the softener filter was bypassed. Two different water samples
were selected (Bore Well Water and Surface Water) and jar test was performed with the Strychnos potatorum Linn extract to arrive the best suited dose for the turbidity reduction. Here the jar test performed with different concentration of Strychnos potatorum Linn extract starting from 20 mg/l to 60 mg/l and selected the concentration of 60 mg/l as the best suited dose for
turbidity reduction. The selected concentration was used for a pilot plant study in the existing water treatment plant designed by M/s. Green Enviro Polestar. The study showed the turbidity removal efficiency of 40% to 60% and highly emphasizes the usage of Strychnos potatorum Linn seed extract as a natural coagulant in water treatment systems.

Investigating the bacterial inactivation potential of purified okra (Hibiscus...AZOJETE UNIMAID
The ability of purified okra protein (POP) as coagulant and as disinfectant material in comparison with aluminium sulphate (AS) in water treatment was assessed. A laboratory jar test experiments and Colilert-18/Quanti-Tray method of bacterial analysis were conducted using POP as coagulant in treating river water. The results show an excellent dual performance function of POP against the conventional coagulant, AS in drinking water treatment. It was observed that a marked inactivation of approximately 100% of faecal and E-coli count in raw water was achieved with POP and zero regrowth of bacteria after 72-hour post treatment. However, there was regrowth in total coliform count as a result of the presence of other microbes other than E-coli and faecal coliform in the system. In all cases AS showed a reduced performance against the two indicator organisms achieving only 93% with remarkable regrowth of E-coli and faecal coliform after prolonged storage time in the clarified water. Turbidity removal was also noted to be approximately similar, 92% across all coagulants tested. Therefore, the use of POP in water treatment could improve access to clean water in developing countries and could help in reducing the import of water treatment chemicals.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

---------------------------------------------------------ABSTRACT------------------------------------------------The menace of indiscriminate wastewater disposal has been an age long concern of every environmentalist.
Moringa oleifera was used as a coagulant to treat wastewater and have been found to be effective. In this paper,
a comparison has been made using Moringa oleifera extracts in its ordinary state and after extracting the oil
content, in the treatment of Abattoir wastewater. Parameters investigated include both the chemical, physical
and biological parameters before and after the treatment process. Jar test was conducted to obtain the optimum
dosages in both cases.The optimum dosage obtained when 10% concentration of both ordinary and de-oiled
moringa, hitherto identified by MPS (moringa powder solution) and MCS (moringa cake solution) respectively
was 1.1mls.This was at the flocculation speed of 90 revolution per minute and in 1hour contact time. Soxhlet
extraction was done to extract the Moringa oleifera oil using Hexane as solvent in the extraction process.
Significant turbidity removal from 218.4NTU to 42NTU which translated to 80.77% was observed when deoiled moringa was used, as compared with that of ordinary moringa which reduced from 218.4NTU to 68NTU
being 68.86%. At 2hrs. contact time, pH reduced from 2.74% with the use of MPS to1.98% after using MCS.
The BOD of 73.68% reduced to 68.42% at 90rpm when MCS and MPS were used in the treatment process
respectively. Similar trend was observed in the other parameters considered. This research revealed that deoiled moringa oleifera performed better in abattoir wastewater treatment as compared to ordinary moringa.The
result was compared with the W.H.O standard and found to be within the acceptance limit.

INTRODUCTION
Wastewater discharge from slaughter houses constitute health hazard and pollution of the water bodies
leading to the extinction of aquatic animals (Agravel et al; 1994, Kannan et al; 2008).This waste essentially
composes of blood, urine, meat, soluble protein excretes, fats, feacal matter and assorted particles. These
composition forms a good medium and substrates for the growth of pathogenic micro organisms which has been
identified to endanger the health of man. ( Kannan et al; 2008 ). The need to treat this wastewater for possible
recycling is of paramount importance in providing healthy environment and eliminating the odor posed by this
waste, in addition to its unaesthetic presentation. Most industries are unable to treat their waste products
adequately due to the high cost of chemicals conventionally used in treating the wastewater being generated, this
is in addition to the high exchange rates, beside these chemicals are eventually hazardous to health Jahn
(1981,1986,1988). This has led to the exploring of alternative substances that are biodegradable, nontoxic,
environmentally friendly and locally available. One of such is the moringa oleifera (Jahn, 1981; Kawamura,
1991; Grabow et al; 1985).Researchers have established that Moringa oleifera seed has high antimicrobial
activity and strong coagulating properties for sedimentation of suspended particles in developing countries (.
Studies have shown that the active ingredient responsible to making this substance an effective coagulant is the
diametric cation peptides isoelectric point ranging between 10 and 11. (Gassen et al; 1990; Anwar et al, 2007;
Jahn, 1981, 1986; Olsen, 1987). Gassenchmidt et al; 1991). This is a deciduous tree of the moringaceae family
popularly referred to as the wonder tree, owing to its variety of applications which includes its medicinal value,
as a cosmetics, due to amino acid content, minerals and vitamins (Fuglie, 2001; Laurence,1965). The leaves,
fruits and flower of this tree forms one of the traditional diets in many countries. (Siddhuraju and Becker2003;
Anhwange et al; 2004). The seed extract of this substance has been severally used to treat turbid water with high
degree of success (Muyibi et al, 1995; Ndabigengersere et al, 1995).Furthermore, Muyibi et al (2002) had
studied the effect of oil extraction from Moringa oleifera coagulant on raw water and have attained 97%
turbidity removal.

Ademiluyi (1990),extracted the moringa oiled and used the cake to improve its sludge conditioning
potential, after comparing its efficiency with the ordinary moringa, He concluded that the oil-free moringa has
higher conditioning potential than the ordinary moringa. Suleyman et al; (2003).carried out a selective oil
extraction and used the cake to treat raw water samples with an appreciable success. Whereas the researcher
used petroleum ether as the solvent in the extraction process, in this work, hexane was preferred and used for the
same purpose. The speed of flocculation was also varied to ascertain the speed that favors best flocs formation.
In light of the success attained in treating wastewater and raw water samples, this work is set out to compare the
treatment performance between the ordinary and de oiled moringa oleifera in abattoir wastewater treatment,
with the view to identify the best form this substance should be used. When this is achieved, it will eliminate the
odour, pollution and unaesthetic characteristics associated with slaughter houses and help the economy and
hygiene of developing countries.
II.
MATERIAL AND METHODS
2.1 Material Samplings.
Matured and dry moringa pods (30-60cm length) were collected, the seeds were removed and pounded
manually using pestle and mortar, it was then sieved with 0.06mm BS sieve to obtain a fine powder, sealed in
polythene bags. 120gms of the powdered moringa was weighed and shared into two equal portions. 60gms was
subjected to oil extraction using electro thermal soxhlet extractor where hexane served as the solvent and the
process executed. The cake after extraction was dried and crushed to form de-oiled moringa seed powder.
10grams of the ordinary moringa powder and of the de-oiled were made up to 100ml with distill water, mixed
and filtered to obtain stock solutions respectively.
15litres of abattoir wastewater sample was collected from slaughter house drain path at Markurdi (by river
Benue Bridge) by composite sampling method, into a cleaned rubber jerry can and brought to the Benue state
water works laboratory for analysis. the initial waste water quality was determined in line with the standard
method of waste water measurements (APHA, 1995).
2.2 Analysis
Jar test was performed to obtain optimum dosages using jar test apparatus JLT4 velp scientific. 500ml
of abattoir wastewater were poured into 6 no. beakers of 600mls capacities, this set up was placed in a
flocculator, the six paddles were lowered into it. Varying dosages by serial dilution method were applied and the
machine was operated with speeds in revolution/min.
2.3 Preliminary investigations.
The initial wastewater quality was determined in line with the standard method of wastewater
measurement APHA (1995).To determine the effect of the ordinary moringa seed powder and de-oiled moringa
oleifera, samples of abattoir wastewater were measured in the 6 beakers of 500mls capacities and placed under
flocculator. The paddles were lowered and the flocculator speed varied from 30 to 270 revolution/min. 10%
moringa powder stock solutions (MPS) and moringa cake solutions (MCS) were prepared respectively. After
filtering out this solution, varying doses ranging from 0.8-1.2 each were dropped into 5 of the six wastewater
bakers respectively, and the flocculator was operated from 30min to 2hrs. The paddles were then lifted out of
the samples to allow the flocks formed to settle.
2.3.1 Physical Qualities
The abattoir wastewater physical qualities were determined with particular reference to its temperature,
turbidity, suspended solids, colour and odour. While the spectrophotometer HACH 1991 was used in
determining the turbidity, suspended solids the total solids and colour. In which cases the abattoir wastewater
was measured in a 25ml capacity bottles and placed in the sample cell, when the respective programmed
numbers were entered, the reading was displayed in NTU and recorded
2.3.2 Chemical Qualities
Similarly, chloride and iron were determined by the use of spectrophotometer, pH meter HACK 1991
was used to determine the pH of the samples, and potassium permanganate was used in determining the
chemical Oxygen Demand (COD) as recommended by (Hammer,1977).
2.3.3 Biological Qualities
Dissolve oxygen DO2 (i) was determined using the oxygen meter model 71 by HACK. The probe was
immersed into distilled water to adjust the reading. Subsequently the probe was immersed in the Abattoir
wastewater and the reading recorded. The DO2 (s) was also determined in similar manner. Subsequently the
BOD was obtained by calculation.

The Coliform counts were determined through the use MacConkey broth as a reagent with wastewater
samples in bottles were incubated in an autoclave condition. The number of positive bottles were identified and
recorded accordingly.
III.
RESULTS AND DISCUSSION
Preliminary observations
Results revealed that the samples physical characteristics had initial turbidity of 218.4NTU, total
dissolved solids, of 108.4mg/l, suspended solids had a value of 188mg/l and the total solids was 296.4mg/l. The
sample temperature obtained was 32oC while colour was 450pt0 On assessing the chemical quality, result
indicated that the sample had the pH of 6.58, hardness 240mg/l, Fe 2.42mg/l, chloride was 42.7mg/l and
chemical oxygen demand (COD) 372mg/l. While in the case of the bacteriological, the DO 2 (i) was 4.4mg/l with
the DO2(ii) of 1.9mg/l and the calculated BOD was 152mg/l. The total coliform per 100ml of water was 1,800.
The results of the experimental analysis are as shown in figures 1-18. The assessed parameters indicating the
performance of the treatment using moringa powder solution (MPS) and moringa cake solution (MCS) are
presented and discussed.
Physical parameters
The increase in speed of flocculation which was varied from 30 to 270 revolutions per minute using
10% concentration of the solution had no significant effect on the temperature of the sample, seeing that the
initial temperature 32oC only resulted to a marginal change ranging between 30.9-31oC. However, the result
revealed optimal performance at 90rpm when either(MPS), or (MCS) was used as shown In fig.1-6. at this
speed, the initial turbidity of 218.4NTU was significantly affected and reduced to as low as 38NTU when MCS
was used which translates to 85.75% turbidity removal, as compared to the use of MPS, where the initial
turbidity reduced to 42NTU being 80.77%. in the case of moringa powder solution (MPS). This optimum
performance attained, could be attributed to the moderate agitation that enhances flocs formation commonly
associated with this coagulant which agrees with the findings of Aho et al, (2012). Further increase in speed
resulted into the loosening of the particles bonds The MCS being oil free provided easy flocs formation, this
goes to show that the presence of oil in moringa oleifera interferes with the treatment efficiency, as the oil forms
a coating round the substance and inhibit contact with the suspended particles in the treatment process. This
speed further favors the agglomeration and subsequent settlement. The relatively low temperature of 30oC at 1hr
contact time recorded in the case of MCS must have enhanced the fast settlement of the flocs formed which
agrees with former works that confirmed that at low temperature, particles have greater tendencies of
settling.Contact time was also varied from 10mins to 2hrs after introduction of MPS and MCS respectively, An
excellent performance was observed after 1hr contact time on using MCS, where the initial turbidity was
reduced to as low as 10NTU which amount 95.4% and to 20NTU being 90.4% turbidity removal when MPS
was used. The initial total solid also reduced to 40.2mg/l and 35.4mg/l being 81,71% and 85% in 1hr contact
time when MPS and MCS were used respectively.

concentration of MPS and MCS in fig. 7 to 12. The most significant of the abattoir waste water quality was at
1hr contact time when the initial COD dropped to 68NTU which translate 81.72% when MCS was used as
compared with 80% reduction in the case of MPS. this optimum contact time resulted to a significant reduction
in the organic matter present in the abattoir waste. the pH value reduced to 6.40 at 2hrs when MPS was used, as
against the 6.45 recorded for MCS, this is a better improvement in the waste water quality treated with MCS
whereas, with MPS the waste water tend to be more acidic indicating the presence of uric acid. the iron content
which was initially low, further reduced to 0.28 and 0.32mg/l with the introduction of MCS and MPS
respectively.

3.4 Bacteriological parameters
The biological qualities investigated and treated are the coliform and BOD. the dose that resulted in the
significant reduction of coliform bacteria was 1.1mg/l where the initial coliform of 1800cfu reduced to 170cfu
being 90.56% when MPS was used whereas for MCS, it was reduced to 130cfu being 92.78%. However, the
most significant coliform removal was attained at 1hr contact time after flocculating at 90rpm.In when case,
with the introduction of MPS 97.94% reduction was attained and as high 99% bacteria removal was made
possible using MCS. The efficiency demonstrated by these substance, is revolutionary as it is pointing at

potential of its being used as a disinfectant in waste water treatment. Similarly the performance of this coagulant
in reduction was highest in the case of MCS at the same speed of 90rpm within 1hr contact time were the initial
BOD came down to 37mg/l and 34mg/l representing 75.65% and 77.68% using MPS and MCS respectively.
This indicates that bacteria response to treatment requires more time.The contact time after flocculation at
90rpm was varied from 10min to 2 hours in this experiment and 1hr turned out to be adequate enough to clarify
the abattoir waste water when either the MPS or MCS was used.
IV.
CONCLUSION
The initial abattoir wastewater treated revealed high values of contaminant in all the parameter studied,
capable of endangering the environment and hazardous to human and animal health.The results of the use of the
de-oiled moringa oleifera in abattoir wastewater treatment revealed higher performance compared to the use of
the ordinary moringa as can be seen from the figures presented. The use of either the ordinary or de-oiled
moringa had very little effect on the pH of the abattoir wastewater. The Fe content in abattoir wastewater is
generally low. The highest turbidity removal from 218.4NTU to as low as 68NTU which is attained with the use
of MCS. This clearly shows that the oil content in moringa inhibits its treatment performances. The entire work
revealed optimum dosage of 1.1mg/l, speed 90rpm and 1hr contact time to be optimum when 10% concentration
of ordinary and de-oiled moringa oleifera was applied in the treatment process.It is however recommended that

the concentration of the stock solution of ordinary and de-oiled moringa used in the abattoir wastewater
treatment be increased to 20% in subsequent research to observe any possible improvement or not of the
wastewater quality. The results obtained from this work compares favorably well with WHO standard.
