This study may be divided into two parts.
- 1. PRIMARY: In the primary treatment study, we carry out various experiments, with the aim of removing suspended and dissolved matter, with combination of various chemicals and by varying conditions. In this study we can come to optimum doses of chemicals, and provide valuable inputs for Design of plant
- 2. SECONDARY : In the secondary treatment, we carry out a Bio-degradation study.
The Primary treated waste is inoculated, with bacteria from the milieu (soil&sewage etc).
Here we get to know the extent of biological degradation possible, the time needed for degradation, and many other factors needed for Design.
if we find that routine procedures are not working we go development of special cultures, based on techniques of isolation and adaptation.
