Electrically Operated Decanters (EOD)

The Mercater Electrically Operated Decanter (EOD) system is a simple idea with only one moving part. It is ideal for use in intermittent extended aeration plants. The low voltage actuator drives a rotary valve to cause the stilled treated effluent to flow by gravity to a contact balance tank or direct to lagoons. Decant start and decant stop are positive and not reliant on air locks type system which can fail by leakage over time.


Effluent Reuse Systems – Design, Construct, Operate & Maintain

Our plants can meet the stringent requirements for biological oxygen demand (BOD), nutrient and suspended solids removal and disinfection control, as required by controlling bodies such as Department of Health (DofH) and Environmental Protection Agencies (EPA). We have extensive knowledge of package treatment plants including filtration (membrane and mixed media), chlorination and UV disinfection. We also have the capability of providing the associated irrigation or delivery systems including pump stations, piping networks, irrigation disposal systems, etc.
