Water treatment specialist A3 Water Solutions, a subsidiary of EnviTec Biogas, has developed a membrane bioreactor process in conjunction with EnviClear that purifies contaminated surface waters for biogas plant operators.
The process has now been put to practice for the first time at the plant of Biogas Greven e.V. and was officially inaugurated last Monday in Greven.
The 1.2 MW biogas plant of Biogas Greven e.V. is EnviClear’s first operation site.
Biological treatment plant operation with the membrane bioreactor process in Greven aims to ensure compliance with the applicable discharge limit values. Until now, the operator had been using a wastewater treatment pond with a downstream reed bed treatment plant. With this method, contaminated water would sometimes end up in the nearby creek Menningbäumer Bach.
The wastewater treatment plant is based on the membrane bioreactor process (MBR), in which the wastewater is purified biologically, and the biomass is retained by submersed membrane filters. The filters are so fine that they also capture bacteria, thus ensuring an especially high-quality process and a purification capacity of over 99 percent, the company says.
The plant can also be remotely monitored.
