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.

|
Pithampur IDA about 45 km from Indore has industries ranging from automobiles, pharmaceutical to textiles. The watersheds of two rivers namely Gambhir and Chambal, constitute the two study areas. The Gambhir and Chambal river have sub-parallel to dendritic drainage pattern. Thin quaternary alluvium consisting of clay, silt, fine to coarse sand, kankar and gravel is restricted to narrow patches along the course of rivers. Deccan trap basaltic rocks of Malwa group of Cretaceous to paleogene age (68-62 m.y) cover the entire area of the district. The region is characterized by lava flows of "pahoehoe" and "Aa" type. Mega-porphyritic flows sit at the top of the formations. The rocks belong to upper-cretaceous to paleogene age. The rocks have only secondary porosity in the form of fractures and joints. The aquifer type is mostly unconfined and semi-confined. The topsoil cover is predominantly clay. Gambhir river watershed covers an area of 90 sq km and industries located in this are mostly from automobile and chemical sector. Chambal river watershed has industries mostly from the automobile, chemical, textiles and pharmaceutical sector and covers approximately 210 sq.km. Apart from the existing industries, the area is going to witness further industrialization with a new Special Economic Zone (SEZ) coming up in the region. Integrated geohydrological, Remote sensing geophysical investigations carried out during last 2 years has helped generation of geohydrologic the database. Groundwater flow and mass transport modeling has been carried out to characterize the size of contaminant plumes, if any for present scenario.

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.

Evaluation of water quality and biodiversity in the submergence area for the proposed Middle Vaitarna Dam, (Year : 2017)
|
Objective:
The Municipal Corporation of Greater Mumbai (MCGM) has proposed to develop additional source of drinking water supply due to increasing demand of water requirement for the megapolis of Mumbai. The project envisages the development of impoundage through construction of Middle Vaitarna dam to provide 455 MLD of water supply to the city. The raw water conveyance system is proposed from Modak Sagar (Lower Vaitarna dam) through a 7.5 km long tunnel of 3.5 m dia. upto Bel-nalla followed by 3.0 m dia. MS pipeline parallel to the existing pipelines in three parts on municipal land transporting raw water to proposed new Bhandup water treatment plant. The MCGM will execute the various components of this IV Mumbai Water Supply Project. As a result of construction of Middle Vaitarna Dam, approximately 630 ha area of forest will come under submergence. In order to estimate the loss of biodiversity caused due to submergence, it was felt necessary to conduct the study, so that ecosystem restoration programme as per MoEF guidelines can be initiated by the sponsor.
Scope:
- Evaluation of major vegetation in submergence area following quadrant method
- Application of diversity indices with reference to importance value index (IVI) of the area
- Ranking the varieties of trees starting from most important to least important species
Summary:
The major environment components studied during the survey of submergence area at MVD in March 2007 is land and biological environment. The terrestrial component in the proposed Middle Vaitarna dam project indicates that there will not be any appreciable changes as envisaged in the earlier reports on (A) EIA report of Middle Vaitarna Dam (B) Enumeration of trees for IV Mumbai (Middle Vaitarna) water supply project and (C) Catchment Area Treatment Plan. The review of all the reports for protecting the environment due to project activities, the present situation at the project site, the financial allocation for preservation of environment reveals that the project may be taken up for implementation. The environmental management plan suggested in the comprehensive EIA report and the requirements of forest department may scrupulously be followed to maximize the overall benefits apart from additional water supply need for the mega city of Mumbai.

CSIR Networked Programme on Pollution Monitoring Mitigation Systems and Devices (SMM-05), (Year : 2018)
|
In CSIR Networked Programme (SMM-05) one of the component is estimation of assimilative capacity of environmental media (air, water, land and biological), which has to be dealt by NEERI in three regions viz. Central India – Nagpur (M.S.) and Chhindwara (M.P.) districts, Coastal region - Visakhapatnam district (A.P.) and Hilly region - Mandi and Bilaspur districts (H.P.). The aims of the study are to develop the methodology for estimation of assimilative capacity with respect to various pollutants under different management options and development scenario; and delineation of assimilative capacity based standards for water sources for sustainable development. A meso-scale database on assimilative capacity of environmental media (air, water, land and biological) is essential for understanding the status of environment and for developing environmental quality standards, which will help easy and transparent decision making at policy, plan and project levels. A database for three representative regions would be generated, which would be available in public domain. Water quality analyses of major water resources of the two regions viz. Central India and Coastal region were carried out during post-monsoon as well as critical seasons. The analytical results showed that majority of water resources fall within the permissible limits of drinking water standards except coliform bacterial counts. It is observed that the water resources are suitable for irrigation purpose with few exceptions. Spatial variation in surface and groundwater quality was observed depending upon geological strata, pollution load by point and non-point sources and local ongoing practices in catchment area. The problem is aggravated in critical season, as pollution and chemical ingredients get concentrated in small amount of water resources. This calls for proper catchment area treatment strategies for surface water resources and conservation and protection of groundwater resources from being polluted. Using these resources for drinking purpose require proper water treatment with disinfection, whereas for irrigation purpose it requires adoption of proper irrigation methods and scheduling of irrigation in order to prevent water logging and salinity problems of land resources. Pollutants assimilative capacity of soils varies depending upon their intrinsic properties. One of the components in this project is Lysimetric study for Soil - Wastewater interaction. These studies will help in determining horizon wise pollutant retention capacity of soil, which will entail about quantum of groundwater pollution at wastewater application sites vis-à-vis soil pollution.
