S.K Singh, Bimal Jain, Twinkle Bhatia.

Abstract
Wastewater is defined as the contaminated sewage discharging from various sources such as residential, commercial,
agricultural as well as industrial sites. It is produced by anthropogenic activities which is done at source through various
processes. The wastewater from residences and organizations carries wastes such as urine and human feces, food waste
and wastes coming from washing etc. are categorized as sanitary sewage or domestic sewage. sewage is produced every
day by human activities and various industrial processes. The sudden intensification in the residents of the country and
the essential need to meet the growing demands of domestic and industrial consumption, irrigation, and the existing
water resources in various portions of the country are receiving exhausted, and the water quality get worse. Almost all
surface water sources have been polluted to particular extent by organic pollutants, bacterial contamination and make
them unfit for human feasting unless disinfected. The contaminated water increases many diseases such as typhoid,
cholera, gastroenteritis, bacterial dysentery, hepatitis, poliomycitis, dysentery etc. The wastewater from every house and
organizations, carrying bodily wastes (primarily urine and feces), food preparation and washing water wastes, and other
waste harvests of usual existing, are categorized such as domestic or sanitary sewage. Organic pollutants and nutrients
Sewage have been multifarious assortment of chemicals, with numerous distinguishing chemical appearances. These
comprise in elevation concentrations of NH3, NO3, N2, phosphorus, high alkalinity, with pH characteristically oscillating
between 7 and 8. The organic matter of sewage have been measured by formative its biological oxygen demand (BOD)
or the chemical oxygen demand (COD). The sewage containing liquid and solids coming from the domestic sites can be
treated with the help of various conventional processes such as Trickling Filter, Activated Sludge Process, Rotating
Biological Contractors, etc. One of the prime objectives of sewage treatment is to safeguard the environment; social
economic and public health from the pollutants. This treatment based or depends on the (Primary, Preliminary,
Secondary or Tertiary 2 treatment). The aim of public and waste water treatment is to remove pollutants and toxicants,
neutralize abrasive particles, and eradicate pathogens so that quality of cleared water is enhanced to extent the allowable
level of water to be discharged into water bodies or for agricultural land.
The paper majorly discusses about the Decentralized Wastewater treatment system along with the study of the
performance of 1MLD Bio-filter STP plant at DTU, New Delhi. Moreover, it
studies the evaluation of the overall performance of 1MLD Bio-filter STP plant at DTU, New Delhi.

Key words: decentralised sewage treatment, domestic wastewater, water quality parameters, Vermicomposting.
