EQ Upgrades Wayne Disposal’s Wastewater Treatment Plant

Project demonstrates EQ’s expertise in wastewater treatment projects

Wayne Disposal, Inc. operates a non-commercial wastewater treatment plant. The facility pretreats on-site leachate from the hazardous waste landfill prior to discharge to a local POTW.

The wastewater treatment plant recently installed a membrane biological reactor (MBR) continuous discharge treatment system to replace a batch chemical treatment system. A MBR combines activated sludge treatment with a membrane liquid-solid separation process. The membrane component uses low pressure ultra filtration membranes.

The MBR eliminates the use of granular activated carbon and sodium hypochlorite used in the chemical batch system but is still preceded by chemical precipitation for the removal of heavy metals and co-precipitation of cyanides and PCBs. The MBR treatment system generates a cleaner wastewater and significantly reduces treatment costs.
