Wastewater Treatment Plant Basics: Choosing the Right Process for Your Facility

A quick guide to selecting an ETP/STP approach based on your wastewater characteristics, load variations, and reuse goals.

The best plant is the one that matches your influentโ€”design starts with sampling and realistic operating data.

Key points

  • Characterize influent: pH, COD/BOD, TSS, oil & grease, heavy metals (if applicable).
  • Plan equalization for peak loads and shock events.
  • Select biological process (MBBR/SBR/ASP) with sludge handling.
  • Add tertiary steps when reuse is planned (filtration, carbon, disinfection).
  • Define O&M: chemicals, energy, manpower, spares, and monitoring frequency.

We recommend starting with a pilot or at least a robust jar-test and treatability assessment.
