66-Assessment of Municipal Wastewater Treatment Systems Using Life Cycle Assessment Approach. Bind, Kamala; Under the Guidance of Singh, Omkar With increasing environmental concerns and rapid growth of wastewater in domestic as well as in industrial sector, there is an urgent need to treat the wastewater with lower environmental footprints. Different types of treatment technologies are practice to treat large amount of wastewaters. It was found that there is the research gap of appropriate comparison of wastewater treatment technologies, hence this study was undertaken. Present study investigates the performance of four municipal sewage treatment plants (STP) in India based on different technologies. Environmental impacts of selected STPs were calculated and compared through Life Cycle Assessment tool using CML 2 baseline methodology and Eco-invent database. Only operation and maintenance phase of each technology used in secondary treatment was considered during the study. Four impact categories including, energy consumption, Global Warming Potential, Acidification Potential and Eutrophication Potential were considered. During assessment, four technologies of sewage treatment, namely, Constructed Wetland (CW), Activated Sludge Process (ASP), Extended Aeration (EA) and Submerged Aerobic Fixed Film Reactor (SAFF) were selected. Among the selected STPs, the CWs based STP has found in owing negligible energy consumption and negative Global Warming Potential (GWP) due to carbon sequestration capacity of macrophyte (Canna indica), than other treatment technologies. SAFF reactor and EA process shows almost similar emission impact for all impact categories. The main contributors of environmental impacts of STPs are emission allied with electricity production required for operation of plant.

65-A Project Report on Remote Sensing Applications in Land Use Cover Studies in Haridwar District. Nigam, Pragya; Under the Guidance of Jain, Sanjay Kumar Remote sensing, encompassing the study of satellite data, is a powerful technique for exploration, mapping and management of the earth resources. It is understood to imply the acquisition of information about and object by scientific devices called sensors without being any physical contact between the object and the sensing device. The basic principle involved in remote sensing is each object, depending upon its physical characteristics, reflects, emits and absorbs varying intensities of radiation at different EM wavelength ranges. Using information from one or more wavelength ranges, it is possible to discriminate between different types of ground objects (e.g. water, dry soil, wet soil, vegetation, rocks etc.) and map their distribution on the ground. One of the important remote sensing technique use is aerial photography, Aerial photography has essential remained to the visible part of the electromagnet spectrum where it is only a very fraction of the electromagnetic spectrum. Remote sensing techniques have extended the scope of utilisation of the electromagnetic spectrum to almost its entire range. The electromagnetic radiation (EM) is the source of all signals collected by most remote sensing instruments. The source of this energy varies depending on the sensor characteristics. Most systems rely on the sun to generate all the EM energy needed to image their own energy, called active sensors, transmits that energy in a certain direction and records the portion reflected back to features within the single path.

64-A Project Report on Anionic and Cationic Analysis of Alaknanda River by ION Chromatography. Yadav, Priyanka; Under the Guidance of Jain, C. K. Water is a transparent fluid which form the world 's streams, lakes, oceans and rain and is the major constituent of the fluids of organisms . As a chemical compound , a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds . Water is a liquid at standard ambient temperature and pressure , but it often coexist on earth with its solid state , ice and gaseous state, steam (water vapour). Even today man has brought about changes whether through urbanization and growth of population centre by introduction and employment of auxiliary means in agriculture which has disturbed or destroyed the natural healthy quality of water bodies .

63-A Project Report on Analysis Of The Ground Water Samples Of Guwahati By ION Chromatography. Saini, Aakanksha; Under the Guidance of Jain, C. K. Water is an important part of human life. Without water no one can survive on the earth. It is the medium of life. About 97% of total water are in saline form in oceans and remaining 3% in fresh form. On land more then 74.9% of fresh water is in the form of ice at the two poles [north and south] and about 30% is in the form of underground water. About 0.115% of fresh water is in the form of atmospheric moisture, river, streams, lakes, pools, artificial, reservoirs etc. In which 0.035% in standing form as ponds, lakes and reservoirs.
