    The aim of this work was to study the effect of the traditional thermophillic composting thatcommonly adopted for treatment of organic wastes or for production of organic/natural fertilizersthat is introduced to a related technique, called vermicomposting (using earthworms to breakdown the organic wastes). These two techniques have their inherent advantages and disadvantages. The integrated approach suggested in this study borrows pertinent attributes from each of these two processes and combines them to enhance the overall process and improve the products qualities. Two approaches investigated in this study are: pre-composting followed byvermicomposting.Eisenia fetida(red wigglers) species of earthworms used in the vermicomposting processes. The results indicate that, a system thatcombines the two processes not only shortens stabilization time, but also improves the productsquality. Combining the two systems resulted in a product that was more stable and consistent(homogenous), had less potential impact on the environment and for compost. Vermicompostingsystem, the product met the pathogen reduction requirements.

    (AIKTC, 2017-05) Shah, Dhaval; Choudhary, Mohd. Raquib (12CE15); Kable, Mateen (12CE22); Shaikh, Asgar (12CE50); Shaikh, Abdul (14DCE77)
    Water is the basic need of human. The basic need of human is cooking, washing and bathing. 97.5% of the earths water is seawater and theremaining 2.5% is freshwater found in glaciers and Underground. Desalination is a process of removing salts from sea water. In this report desalination of sea water is based on reverse osmosis method.Osmosis is the spontaneous transport of solvent from a dilute solution to a concentrated solution across an ideal semi permeable membrane.If the pressure is increased above the osmotic pressure on the solution side of membrane, the flow is reversed and water flows from the concentrate to the dilute side, this is called reverse osmosis (RO). RO is based on two variables high flux of water and high salt rejection. Reverse osmosis is a method in which external pressure is applied to the concentrated solution which removes the salts from sea water. In this report, sample water of Arabian sea is taken location is murudjanjira near alibaug. Various tests have been performed on sea water before treatment and after treatment. In various season this test were performed. The various tests which are performed are pH, Turbidity, Conductivity, Total solids, Total dissolved solids, Salinity and Dissolved oxygen. These tests were performed in various seasons such as monsoon, winter and summer.The different values of various test obtained in different season is a comparison of desalinating of sea water before treatment and after treatment. The different values of various test is given in the tabular form and the graph is also plotted. This present study shows the seasonal variation of sea water by passing the sea water through RO membrane. This study will help in various forms to use sea water such as drinking, bathing, clothing, irrigation, etc.

    Pharmaceutical industry is one of the major industries causing water pollution. In India, It generates about Million litres of waste water processed depending upon the process employed and product manufactured. Considering the increased demand for Drugs, the Drug based industries in India is expected to grow rapidly and have the waste generation and related environmental problems are also assumed increased importance. Poorly treated waste water with high levels of pollutants caused by poor design, operation or treatment systems creates major environmental problems when discharged to surface water or land. Considering the above stated implications an attempt has been made in the present project to evaluate one of the WWTP for Drug industry. Samples were collected from six points; Raw effluent [P-1], Oil and grease trap [P-2], Equalization tank [P-3], Aeration tank 1 [P-4], Aeration tank 2 [P-5] and Secondary clarifier [P-6] to evaluate the performance of WWTP. Parameters analyzed for evaluation of performance of WWTP are COD, BOD5 at 20° C, TSS, TDS, oil and grease, Chloride and Alkalinity. Parameters like pH and oil & grease were used to access the suitability of secondary effluent for reuse in gardening or some other purposes. The COD, BOD5 at 20° C and TSS removal efficiency of WWTP were reduced upto very great extent hence it is suitable to dispose it off into water bodies.

    In this project we have discussed about the problem arises on railway track due to submerging of water. This water gets choked up due to having no allowance of proper flow through pipeline available at the side of the railway track .As we done survey on the railway track we saw that there is no proper maintenance done for the drainage system at side of railway track due to which the water gets submerged on the railway causing problem. There are also some pictures showing in our project book about the drainage system conditions. This research focuses on the rainfall induced flooding that it is caused by high intensity storm, rainfall and runoff in the city area that is inundated due to lack of proper drainage system and inefficient management. It ascertains the water logging problem, its cause and its effects on the environment of the city from the perception of authorities of different organizations and people living in different wards of Kurla Corporation. A field survey has been conducted during 2008 in Kurla Corporation. This water logging becomes a burden for the inhabitants of Kurla and creating adverse social, physical, economic and environmental impacts. Disruption of traffic movement and normal life, damage of structures and infrastructure, destruction of vegetation and aquatic habitats and loss of income potentials are the encountered effects of water logging on city life. The storm water becomes polluted as it mixes with solid waste, clinical waste, silt, contaminants, domestic wastes and other human activities that increase the water born diseases.

    (Sardar Vallabhbhai National Institute of Technology, 2016-10-14) Shah, Dhaval; Magar, Rajendra
    Estimation of inflow design flood i.e. Probable maximum flood (PMF) for major storage reservoirs is most important parameter. The consequences of a failure of the structure due to improper estimation of PMF could be calamitous in terms of loss of human lives and damage to property. PMF which is estimated from probable maximum precipitation (PMP) is used as inflow design flood for major projects. PMP is the greatest depth of precipitation for a given duration which is physically possible for an area. Various methods such as statistical, empirical, storm maximisation and transposition approach, and dynamic approach are used for estimation of PMP. This paper presents unit hydrograph method which reflects all physical characteristics of the catchment for obtaining PMF hydrograph. The study area selected is Nira-Deoghar dam which is located on River Nira in the Krishna basin, Maharashtra, India. The outcome of PMF in Indian scenario is very much important since it is directly related to dam safety.

    The project gives a brief description on the Terrace Gardening using Organic Waste and Landscaping at AIKTC. As the world is heading towards the depletion of natural resources and the loss of forest/garden area due to urbanization, there is a dire need of terrace gardens. Due to the population explosion with a house for every citizen in the country, concrete buildings eat all the open areas away. This has created the ecological imbalance, which can cause tremendous harm to our future generations. When we cannot avoid utilizing open spaces on the ground for the construction of buildings and other utilities, then at least the open spaces available above these buildings can be utilized for plantations and gardens to minimize the ecological imbalance, if not eliminate it altogether. There are many benefits of these terrace gardens, such as waste recycling, ecological benefits, energy conservation, water conservation, decorative enhancement of buildings, occupant’s health benefits and attracting birds and insects.
