Understand the complete STP process
Follow our step-by-step sewage treatment guide from screening and biological treatment through the sludge line. Estimate average, peak, wet-weather and phased flows with the wastewater flow guide before selecting plant capacity. Define the inlet works with the mechanical bar-screen selection guide, including peak hydraulics, debris, standby, screenings handling and safe access. Where downstream treatment needs a smaller opening, use the fine-screen selection guide to define aperture, clean and loaded hydraulics, wash water, carryover and MBR protection. For a compact basket option, use the rotary drum screen guide to define feed, active area, opening geometry, cleaning and reject handling. For a channel step screen, use the step-screen guide to define lamella opening, screenings-carpet behaviour, loaded hydraulics, grit, bottom cleaning and discharge height. Where a compact package must screen and lift solids with optional washing or compaction, use the screw-screen guide to define active area, brush contact, screw wear, discharge and controls. Define landscaping, toilet flushing, cooling or other duties with the water reuse planning guide before selecting polishing equipment. For attached-growth treatment, use the MBBR media selection guide to prepare fill, carrier, retention-screen, movement and startup inputs. Use the fine-bubble diffuser selection guide to define oxygen demand, airflow, grid pressure, commissioning and maintenance. For a membrane plant, use the MBR module selection guide to prepare flux, compatibility, cleaning and commissioning inputs. For a reuse proposal, use the UV disinfection selection guide to prepare flow data, water-quality results and quotation inputs.
