Screening
Coarse and fine screens retain rags, plastics and large solids, protecting pumps and equipment.
Screens
Grit & grease removal
Sand, stones and floating grease are separated to prevent wear and clogging.
Grit Separator

Biological treatment
Microorganisms in the aeration tank break down organic pollution; nitrogen and phosphorus are removed.
Surface Aerators
Final clarification
Biological sludge settles and is collected by scrapers; clear water is drawn off the top.
Clarifier Sludge Scraper
Filtration & disinfection
Sand filters and UV/chlorine make the effluent ready for discharge or reuse.
Ultraviolet (UV) Disinfection
Sludge dewatering
Excess sludge is thickened and dewatered on a belt press to reduce its volume.
Belt Press
