How it works
Primary treatment involves the physical separation of suspended and colloidal material from a water or wastewater stream. In many cases, it may also involve chemical coagulation and flocculation to enhance removal efficiencies.
The combination of physical-chemical treatment incorporating dissolved air flotation clarification is one of KWI’s specialities.
