Infrastructural Urban Voids as an Instrument for Homogenous Urban Fabric Case...civej
In historic time social factors around the spatial existing framework generated development of the city. What we see today is contradictory as economic factors govern the growth of the city. Speed of transformation is noticeably high, while the growth of the city majors in a quantity of physical infrastructural development rather than the quality of public life. Ironically, when we look at a newly planned city like Navi Mumbai infrastructural needs sometimes are becoming the reason for the creation of urban voids in the city fabric. This paper is going to focus on Infrastructural linear voids which are cutting the morphology of the city. Urban Infrastructural voids in Kharghar are identified and typologies are formulated by observational study. This paper investigates if we can utilize these Infrastructural urban voids holistically to formulate a network of public spaces to bind the city holistically.

Analysis of Waste Water Treatment in Kaduna Refining and Petrochemicals Corpo...IJERA Editor
Scientific data and results have to be accurate, precise and reliable and are subject to ever increasing scrutiny by
regulators in industry, the environment and medicine, in validation and also in research and development. Given
our numerous environmental problems, the need for accurate, precise and reliable results cannot be
overemphasized in environmental pollution control. This research was undertaken by visiting the analytical
laboratory involved in environmental pollution control in Nigerian National Petroleum Corporation (NNPC)
Kaduna which is known as Kaduna Refining and Petrochemicals (KRPC). Results were taken within a span of
three years at different times of the year. End of month results were also taken for the two receiving rivers
(River Kaduna & Romi River) and effluent from the refinery. The waste water was analyzed using available
instruments in the Refinery such as PH meter, Dissolved Oxygen (DO) Meter, Conductivity Meter, Gas
chromatography, burette, pipette, Double beam Spectrometer, and Thermometer. The results showed that many
parameters meet the standard of limit set by the Nigerian Standard Organization but there are many vital
parameters whose limits are very low but not measured for lack of instruments. The point of concern here
becomes the availability of suitable analytical instruments for quality control in the waste water treatment.
Evaluation of Potential Physico-Chemical Ground Water Pollution: a Case Study...EditorIJAERD
Ground water is a large source of water for utilisation in the world. This resource is not easily accessible to
monitor its changes and its deterioration is not easy to reverse. In the current study, physico-chemical parameters of
groundwater for Kiwanja Market (KM) were analysed and compared to the Kenya Bureau of Standards (KEBs) water
quality. The pH, DO, temperature, turbidity, chlorine, iron, water hardness, potassium and calcium were analysed. All the
parameters studied were within the stipulated levels except iron, and chloride for samples from point C (Ebenezer Hostel).
Turbidity for samples from points A and C were above the permissible levels of KEBs standards. The water sampled from
point A and C may require further treatment to allow for domestic use. This analysis revealed to some extent a healthier
system, though further analysis is needed to support this assertion. Continuous monitoring of the groundwater sources
within KM should be taken on regular basis to detect any changes and to sustainably maintain the quality of water within
the required KEBs water quality standards.
Performance assessment of water filtration plants in pakistan - JBESInnspub Net
A study was carried out to evaluate the water quality of filtration plants installed at six different places of Cantonment Board Sialkot, Pakistan to suggest and recommend guidelines for their improvement. Water samples from six Treatment plants and their respective twelve connections (two from each treatment plants) were collected before and after treatment. In this way, total samples were collected and tested. Values of these samples before and after treatment were used for comparison with World Health Organization (WHO) guidelines for drinking water standards. Thirty three parameters including physical, chemical and bacteriological were determined for each sample. The results were satisfactory both chemically and bacteriologically according to WHO guidelines for water quality of treatment plants. The results showed that the samples of water were fit, both before and after treatment plant except for water sample of treatment plant No. IV & V (Before treatment). Total and faecal coliform were found in these samples. Various causes of faecal contamination before treatment may be due to leakage of pipelines, operation at tubewells, layout of freshwater pipes parallel or beneath the sewerage pipes or channels. Disinfection of water at source is recommended to deal with the faecal contamination; otherwise there is no need of filtration plant.
This is the presentation at an international conference, ICOMACE at KGRCET, Hyderabad.. the title of the paper is design of domestic sewage treatment plant for a growing town Ulavapadu, Andhra Pradesh, Andhra Pradesh, India.

NEERI CHENNAI ZONAL LABORATORY CAN BE REFERRED FOR ANY PROBLEM OF
4. ENVIRONMENTAL POLLUTION
SOME NOTEWORTHY CONTRIBUTIONS OF THE LABORATORY ARE OUTLINED
BELOW:
Duplex Reverse Transcriptase PCR (RT-PCR) for Simultaneous Detection of
Hepatitis A and E Viruses Isolated from Drinking Water Samples
Epidemic outbreaks of infectious hepatitis in developing countries have been associated with
waterborne transmission of Hepatitis A and E viruses. The lack of standard and reliable
technique for concentration and isolation of viruses from environmental samples has
impeded the inclusion of viruses in water quality surveillance programmes.
The sensitivity of Granular Activated Carbon (GAC) based Urea-Arginine Phosphate Buffer
(UAPB) protocol developed at the Institute encouraged its application in development of
Duplex RT-PCR to detect Hepatitis A and E viruses isolated from water samples.
HAV and HEV were concentrated from water samples through one step concentration
protocol. Two different sets of primers, specific for HAV and HEV cDNA, were used for PCR
amplification. Amplified DNA products, representing Hepatitis A and E viruses, were
identified by gel electrophoresis at 225 and 343 bp sequences, respectively. Specific sets of
primers amplified a single virus and no cross reactivity of the primers was noted in Duplex
RT-PCR.
The protocol was used for direct isolation and detection of HAV and HEV from 23 water
samples drawn from urban areas in Chennai. Nine water samples were positive for HAV, and
three for HEV. All three samples positive for HEV were also positive for HAV. The protocol
provides a rapid and economical means of water quality monitoring in detec tion of Hepatitis
A and E viruses in a single reaction.
5. Decolourization and Biodegradation of Azodye Industry Wastewater
- DBT, Govt. of India, New Delhi
The studies being carried out for the last 3 years included isolation of specific
microorganisms for the degradation and decolourization of different azodyes used in the
textile dyeing industries. Both anaerobic and aerobic organisms were isolated and cultured
by enrichment technique and these isolated microbes were used in batch experiment as well
as in column after immobilization. The environmental conditions for the degradation and
decolourization were optimised.
The studies indicated very good removal and biodegradation of colour in terms of COD
reduction. The azodye degradation pathways were established. Studies are under progress
on the live wastewaters from the dyeing industries.
6. National Ambient Air Quality Monitoring
Air pollution poses a major risk to human health and requires for its management a reliable
air quality data base. To fulfill the societal obligations, NEERI has been operating an Air
Quality Monitoring Network for more than a decade with partial financial assistance from
Central Pollution Control Board (CPCB) under National Ambient Air Quality Monitoring
(NAAQM) programme. The Ambient Air Quality Database has been generated for the last
two decades for ten major Indian Urban Centres viz. Ahmedabad, Chennai, Delhi,
Hyderabad, Jaipur, Kanpur, Kochi, Kolkata, Mumbai and Nagpur.
The Database has helped in determining the longterm air quality trends in Indian urban
7. environments and assisting in development of air quality standards and preparing the
framework for development of viable air pollution management plans. The Programme
includes analyzing long-term trends with respect to health related criteria pollutants such as
inhalable dust, sulphur dioxide, nitrogen dioxide, ammonia and other pollutants viz. toxic
polycyclic aromatic hydrocarbons and trace metals.
In Chennai the monitoring is being done at 3 sites, Taramani (Residential), Park Town
(Commercial) and Thiruvottiyur (Industrial). The Ambient Air Quality Status of these Sites
from January 2003 to August 2003 is presented in the figures.

9. Solidification & Stabilization of Electroplating Waste
One of the major hazardous waste generating industries is the electroplating and metal
finishing industry due to the presence of high concentrations of heavy metals such as Cr,
Pb, Ni, Cu, Fe, etc. Solidification/Stabilization (S/S) technology is one of the techniques now
gaining momentum as a possible solution for many hazardous wastes. Solidification refers
to techniques that encapsulate the waste in a monolithic solid of high structural integrity.
The encapsulation may be of fine particles (micro-encapsulation) or of a large block or
container of wastes (macro-encapsulation). Stabilization refers to those techniques that
reduce the hazard potential of a waste by converting the contaminants into their least
soluble, mobile or toxic form. The sludge under study has been collected from a medium
scale electroplating industry with around 85-90% moisture content. The characteristics of
the sludge are given in Table.
Metal Dry Sludge
(mg/l)
TCLP
(mg/l)
Cadmium 0.006 0.019
Chromium 203.8 235.8
Lead 0.09 2.20
Zinc 36.4 24.5
Objectives of the study were to fix the metal pollutants, to reduce the leachability to
maximum extent, improve the handling and physical characteristics of the waste and
decrease the surface area across which transfer or loss of pollutants can occur. This was
established using cement-flyash and cement-lime system. The sludge taken was 60 and
70%. The lime and flyash content was kept constant at 10% and the rest was cement.
Toxicity Characteristic Leaching Procedure (TCLP) has shown values lesser than the
regulatory limit of USEPA on the 7th day of curing. UCS values for the blocks ranged from
105 to 80 psi in cement flyash system, while the same were 80 to 65 psi in cement lime
10. system. Other leaching test such as Multiple TCLP, NEN 7341 and ANS 16.1 were conducted
on 60% sludge containing blocks as they showed the maximum UCS. Multiple TCLP and NEN
7341 proved 97-98% fixation of Chromium. ANS 16.1 test data, when modeled to fit a plot
of cumulative fraction leached against square root of time, clearly indicated a straight line
which proved that the leaching process is diffusion controlled. The leachability indices were
found to greatly exceed the guideline value in both the systems. The surface morphology of
the blocks was analysed and SEM photographs clearly indicated the presence of euhedral
and prismatic ettringite crystals. The cement-lime system showed the presence of calcite
and diadochy mechanism for fixation of Chromium.
