UASB reactors. Anaerobic treatment for high-strength effluent — no aeration power, no chemicals, and biogas you can use.
What is a UASB?
An Upflow Anaerobic Sludge Blanket (UASB) reactor treats wastewater with a dense blanket of anaerobic bacteria. Effluent enters at the bottom and rises through the blanket, where the bacteria break down the organic load and release biogas.
Because it removes the bulk of the organic load before any aeration, the stages that follow are smaller and cheaper to run.
Why a UASB
Lower powerNo blowers needed in the anaerobic stage.
Biogas recoveryUsable as fuel for boilers or heating.
Less sludgeFar less sludge than aerobic treatment alone.
Chemical-freeBiological treatment, no dosing.

Questions
When does a UASB make sense?
When your effluent carries a high, mostly biodegradable organic load — typical of dairy, food, distillery and similar plants. For low-strength effluent, aerobic treatment alone is usually simpler. We confirm this with your effluent analysis.
Does a UASB replace the rest of the ETP?
No. It removes the heavy organic load first; aerobic treatment, clarification and filtration then polish the water to discharge norms.
