Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

3. 8.3.2.2 When the heat-treating temperatures are the same
and the furnaces (either batch or continuous type), are con-
trolled within 625 °F [614 °C] and equipped with recording
pyrometers so that complete records of heat treatment are
available, then one tension test from each heat is required
instead of one test from each heat in each heat-treatment
charge. The test specimen material shall be included with a
furnace charge.
8.3.3 Testing shall be performed as specified in Specifica-
tion A961/A961M. The largest feasible round specimen shall
be used except when hollow cylindrically shaped parts are
machined from seamless tubulars. When hollow cylindrically
shaped parts are machined from seamless tubular materials,
strip tests may be used. The tension test specimen shall be
obtained from a production forging, or from an integral
prolongation representative of the hub location of a flange, or
the heaviest cross section of a fitting, valve, or other part within
the scope of this specification.
8.3.4 Forgings too small to permit obtaining a subsize
specimen of 0.250 in. [6.35 mm] diameter or larger parallel to
the dimension of maximum working, and produced in equip-
ment unsuitable for the production of a separately forged test
bar such as an automatic or semi-automatic press, may be
accepted on the basis of hardness only. One percent of the
forgings per lot, where a lot is the product from a heat, or, if
heat treated, the product of a heat per furnace charge, or ten
forgings, whichever is the lesser number, shall be selected at
random, prepared, and tested using the standard Brinell test.
The locations of the indentations shall be at the option of the
manufacturer but shall be selected to be representative of the
forging as a whole. One indentation per forging shall be
required but additional indentations may be made to establish
the representative hardness. The hardness of all forgings so
tested shall be 137 to 187 HBW inclusive.
8.4 Hardness Tests:
8.4.1 Two hardness tests shall be made for each heat of
as-forged components. When more than one forging is pro-
duced from each heat, a minimum of two forgings shall be
tested with one reading from each forging. When only one
forging is produced, it shall be tested in two locations.
8.4.2 Except when only one forging is produced, a mini-
mum of two forgings shall be hardness tested per batch or
continuous run as defined in 8.3.2.2 to ensure that forgings are
within the hardness limits given in Table 2. When only one
forging is produced, it shall be hardness tested in two locations
to ensure it is within the hardness limits given in Table 2.
8.4.3 Testing shall be as specified in Specification A961/
A961M. The purchaser may verify that the requirement has
been met by testing at any location on the forging, provided
such testing does not render the forging useless.
9. Hydrostatic Tests
9.1 Such tests shall be conducted by the forging manufac-
turer only when Supplementary Requirement S57 in Specifi-
cation A961/A961M is specified.
10. Retreatment
10.1 If the results of the mechanical tests do not conform to
the requirement specified, the manufacturer may heat treat or
reheat treat the forgings as applicable and repeat the test
specified in Section 8.
11. Surface Finish, Appearance, and Corrosion
Protection
11.1 The requirements of Specification A961/A961M apply
to forgings and finished parts.
12. Repair by Welding
12.1 Repair of defects by the manufacturer is permissible
for forgings made to dimensional standards such as those of
ASME or for other parts made for stock by the manufacturer.
Prior approval of the purchaser is required to repair-weld
special forgings made to the purchaser’s requirements.
12.2 Weld repairs shall be made by a process that does not
produce undesirably high levels of hydrogen in the welded
areas.
