Evaluation of Polylectrolyte for Water Treatement, (Year : 2016)
|
Studies on Performance of Polyelectrolyte Developed by Girijan Co-operative Corporation Ltd., Visakhapatnam from Seeds of Strychnos Potatorum for Treatment of Potable Water The polyelectrolytes have been found to act as coagulants or coagulant aids when used in low dosages. Many of them have been used in water treatment processes to improve floc size and clarification,reduce dosage of the metal coagulant and remove organic colour from raw water.The polyelectrolyte are the polymers which, by the action of an acid or alkali, can be converted into charged ions. The naturally occurring ones were described by Cohen as biocolloids. The feature common to both natural and synthetic colloids is the presence of recurring units containing ionizable groups in the molecule. Depending on the chare of the recurring units the polyelectrolytes have been further classified as cationic, anionic and non-ionic. M/s Girijan Cooperative Corporation Ltd., Visakhapatnam retained the National Environmental Engineering Research Institute, Nagpur to undertake the evaluation of polyelectrolyte manufactured by them from strychnos potatorum as coagulant in water treatment and compares its performance with that of alum. Strychnos potatorum Linn. commonly known as clearing nut or Nirmali seed is a source of natural polyelectrolyte. The coagulating action of the seeds is reported to be due to the combined presence of alkaloids and polysaccharides present in them. The aim of the present study is to evaluate the usefulness of polyelectrolyte manufactured by M/s. GCCL Visakhapatnam from Strychnum potatorum in removal of turbidity, fluoride and coliform group of bacteria form and compare its performance with alum. Spiked Testwater The study have been carried out in spiked test water at different turbidity 100-3400 NTU for reduction in turbidity with polyelectrolyte, alum and in combination of both. It is observed that polyelectrolyte is effective at high turbidity and can be used as coagulant and coagulant aid. The further studies for removal of fluoride and coliform group are in progress.

Action Plan for Abatement of pollution in Damodar River, (Year : 2016)
|
Large number of industries in Bokaro-Dhanbad region of Zharkhand and Asansol-Durgapur region of West Bengal came up in the Damodar river watershed since 1960s. The river system alongwith four major dams receive grossly polluted wastewater from the industries and towns located in the watershed. Subsequent to a similar study in 1994 carried out by several organizations including NEERI, Damodar Valley Corporation (DVC ) desired NEERI to evolve pollution abatement strategies under the present circumstances through detailed water and wastewater analysis as well as appropriate wastewater treatment and catchment management practices to prepare a detailed action plan indicating short and long term measures for protecting the rivers and reservoirs in the Damodar River System while developing Comprehensive Water Use Policy for the basin.

Evaluation of Centrally Sponsored Water Supply Scheme under Accelerated Urban Water Supply Programme., (Year : 2015)
|
Ministry of Urban Development, Govt. of India, New Delhi formulated Accelerated Urban Water Supply Programme (AUWSP) in September 1994 with the view to provide water supply facilities in the town having population less then 20,000. The principle aim of the programme is to improve the quality of life and environment of the poor, specially the most vulnerable sections of the population such as women, children; and other deprived sections who do not have access to safe water. In the implementation of AUWSP community participation emphasis on rationalization of tariffs, separate of budget for water supply and sanitation from the municipal budget; subsides for well identified target groups and water conservation. Operation, maintanenance (O&M), distribution leak detection and preventive maintenance along with rehabilitation of existing system are being given priority over new capital works. As per progamme the water supply sector has to be treated as public utility rather than a service. Water supply schemes in 575 towns were approved by the Ministry on March 31, 2001. These water supply schemes are to be operated and maintained by the Urban Local Bodies (ULBs). It was decided that out of these AUWSPs, ten percent of the approved schemes, both completed and ongoing, in different States would be evaluated. National Environmental Engineering Research Institute (NEERI), Nagpur is entrusted by Ministry of Urban Development and Poverty Alleviation to evaluate 36 schemes in 15 States. The schemes to be evaluated are depicted in Fig. 1. The schemes were to be assessed to ascertain the present status of implemented schemes, its influence on economic, social and health improvement, along with the status of financial and institutional setup of the ULBs. The assessment of identified water supply schemes include the nature of actually implemented schemes, the problems, constraints, the bottlenecks, if any, in regard to implementation as well as O & M of the schemes. The schemes to be assessed are 3 schemes in State of Chhattisgarh, 9 schemes in Madhya Pradesh, 3 schemes in Maharashtra, Calangute in Goa, 2 schemes in West Bengal, 3 in Orissa and 11 schemes in North Eastern region during March – December, 2004. During field visit, NEERI team visited the raw water source and treatment unit, water distribution points (PSP) of water supply scheme to see the status of water quality and quantity supplied to the consumers. The information regarding the distribution of water, revenue collection, status of the scheme, quality and quantity of water, tariff structure, impact of scheme on socio economic status and health of consumer is collected through pre-designed proformae and discussion with PHED officials.

Impact of silt disposal from Beas-Sutlej Link (BSL) project on aquatic life in Sutlej river water, (Year : 2015)
|
Beas Sutlej Link (BSL) project, the largest hydro-electric-cum-tunnelling project in the country diverts about 4,716 million cubic meter of Beas river water annually from Pandoh dam in District Mandi, HP into the Sutlej river near village Dehar, upstream of Bhakra reservoir, through a 38 km Water Conductor System and generate 990 MW of power. The Environmental Management Plan for silt disposal form the balancing reservoir at Sundernagar was prepared by NEERI in December 2000 delineating the various options for silt disposal and engineering solution to the critical silt handling and enviro-socio-economic relief to improve quality of life in the study area. One of the option acceptable to the expert committee was the disposal of silt to Sutlej river downstream of Dehar Power House through a tunnel to be constructed parallel to the tunnel which carries the Beas water to Dehar Power house. The committee felt that the studies should be undertaken Fig. 1 : Silt Dredging from Sundernagar Balancing Reservoir to assess the impacts of silt disposal on aquatic life in Sutlej river downstream of the disposal point. Accordingly, assessment of the existing status of water quality and aquatic life of Sutlej and Beas rivers, upstream and downstream of BSL project is completed. Impacts of silt disposal in the settling zone of Sutlej river has been estimated based on size and settling velocity of silt particles, water hydrology and morphology of the river. The Physico chemical analysis of Sutlej river water indicates that all the parameters are within the permissible limits of BIS 10500.
