Characterization of sewage and design of sewage treatment plant for Anjuman-I-Islam's Kalsekar Technical Campus

Abstract

There are two fundamental reasons for treatment of waste water viz. prevention of pollution and thereby protecting the environmental and protecting the public health by safe guarding water supplies and preventing the spread of water borne diseases. when untreated sewage is discharged sewage may be washed up on to the shore, near the point of disposal, where they decomposes and create foul smells and bad odours. The discharged sewage will contaminate the natural body water i.e. river, lake etc with pathogenic bacteria. The Anjuman – I – Islam’s Kalsekar technical campus, New Panvel is important educational institutes in the Navi Mumbai with a large number of students studying in its campus consisting of various department laboratories, classrooms, canteen, bathroom and academic blocks. There will be hostel of 500 students capacity and residential quarters will be constructed in future. It is absolutely necessary to study the Characteristics and behavior of sewage, to ensure its safe disposal. This study will help in determining the degree and type of treatment required to be given to given sewage, and thus avoid the pollution of the source of its disposal. The present study involves the analysis of pH value, total solids, total suspended solids, hardness, acidity, alkalinity, chloride, chlorine, BOD and DO. The samplings of the domestic waste from college have been done in different times of the day to have an average data of the measured parameters. The average values of pH, Turbidity, Acidity, Chloride, Residual Chlorine, Hardness, Total Solid, BOD, DO, Alkalinity. A sewage treatment plant has been designed with the treatment units, a bar screen, an aeration tank and a collection pit.
