Wastewater characterization is the first step to proceeding with treatability studies.

We set the final goals in terms of results and effluent parameters desired, depending on the end goal of the treated water. The various parameters to be analyzed for the effluent at the laboratory are pH, Total Solids, BOD, COD, Chlorides, Sulphates, etc.

After characterization, primary treatment to the effluent for the removal of suspended & colloidal matters from the effluent is established – DAF, Clarifiers, physical treatments etc.

The secondary treatment method is decided after establishing the primary treatment of influent wastewater. The treatment could be anaerobic, aerobic, anoxic – oxidation, photocatalytic – depending on the type of prime contaminants. Sometimes we can also carry out on-site trials, and the costs are discussed mutually with the client.

The primary, secondary and tertiary treatments are run separately in our lab to determine optimum parameters and operating conditions for each stage of treatment at the plant level. Finally, Diva Envitec Engineers take a holistic approach to how wastewater will be treated in the plant and design bespoke solutions.
