Anaerobic treatment partially converts pollution to ammonia, carbon dioxide, water and biogas.
Marel Water Treatment provides different anaerobic processes:
- Voltaflow®, Voltaflot®, Voltamix®
- Voltaflow® UASB
De UASB – Upflow Anaerobic Sludge Blanket: in the UASB, the wastewater is heated to 30 to 35 °C (85 to 95 °F), thermophilic 52 to 55 °C (125 to 130 °F). The residence time of the water is short: between 8 hours and 4 days.
Because of the incomplete degradation, it may be that an aerobic treatment must be connected downstream in order to comply with the effluent requirements.
