Wastewater treatment: design a treatment train, not an isolated device

Performance comes from a coherent sequence of pretreatment, pollutant removal, clarification and disinfection.

Understand the effluent

Flow, organic load, solids, oils, nutrients and specific pollutants determine the process choice.

Screening, grit removal and grease removal prevent coarse materials and fats from disrupting subsequent treatment.

Settling, biological or physicochemical treatment, clarification and disinfection are combined according to discharge or reuse targets.
