A Comparative Study of Physico-Chemical and Biological Analysis of Sewage Water

Authors: Mohit Kumar

When sewage is untreated and is discharged into any water course will be effected severely. Sewage which has many pathogens and is rich in organic matter and high BOD when released into water course the dissolved oxygen of the stream decreases drastically which effects flora and fauna of the stream and also makes the water unfit for any purpose. Visakhapatnam is a city where nearly 18 lakh (384 per km2) (Eenadu, dated on 1st April) people resides. The day – to – day sewage which generates in the city has been collected and treated in the municipal sewage treatment plants at Appugar, Port area, Old town and Mudarsalova. Where Appugar plant holds 25 MLD, Port area plant holds 10 MLD, Old town plant holds 38MLD and Mudarsalova plant holds 13MLD of sewage of Visakhapatnam. The sewage treatment plants are not enough to hold the existing huge volume of sewage that is generated in the city. People and tourists are attracted more towards locations like Lumbini Park, Tenneti Park, Tourists Resorts located along the Beach and make frequent visits to those places. Aim of this study is to estimate physico-chemical and biological parameters of the sewage samples from different sewage disposal points along the coast of Visakhapatnam and to identify that objectionable parameters of the sewage ,which should be minimized before it is being disposed off.
