Mathematical Model for Commercial Production of Bio-Gas from Sewage Water And Kitchen Waste

Utilisation of Bio-Gas is increasingly applied to produce renewable energy to minimize environmental emissions both resulting in reduction of green house gas. Despite Government Grants, the production of Bio- Gas is not commercialized and people mostly depend on natural gas which is non-renewable and depleting fast. The project aims at operation a pilot scale model of 20 litres capacity to evaluate the maximum yield of bio-gas from domestic sewage and kitchen waste. The organic loading and Hydraulic retention time of 25 days will be studied to improve the production of bio-gas and model will be developed. Suggestion and recommendations will be made to commercialise the production of bio-gas. A computer programme will be developed for optimum allocation of the above factors to generate more Bio- Gas based on the feed stock an effluent samples characteristics, such as pH, total solids, volatile solids, number of days, alkalinity, volatile fatty acid. A various digestion options and operational factors will be analysed to make the commercial production of Bio-Gas. A model will be developed with computer programme on the biogas from Kitchen waste and sewage water. The project aims at the usage of distribution of Bio- Gas, is renewable resource instead of Coal, petroleum which are non-renewable resource and fast depleting. Thus when the Bio-Gas is used as fuel in Transportation and Power generation, definitely this will be a mile stone in the economical development of our country
