Sodium Hypochlorite Disinfection - Recirculated (SHDR)


Pilbara Region, Western Australia


The owner of a lithium mine undergoing expansion near Port Hedland in Western Australia required assistance with the treatment of wastewater from a new heavy vehicle (HV) washbay. The requirement was for initial Total Petroleum Hydrocarbons (TPH) reduction via a MAK Water Oil Water Separator (OWS), prior to additional treatment to a level suitable for either reuse in the HV washbay or discharge to environment.

MAK Water designed and manufactured a custom SHDR plant to provide both disinfection and pH adjustment of pre-treated wastewater. MAK Water worked closely with the owner’s engineering consultant to review the HV washbay design, specific site requirements and provide the best possible solution.
