Knowing that TDS = total dissolved solids, the first step is to remove all non-mineral dissolved solids by advanced biological treatment (without adding any chemicals other than nutrients if/as.

The Waste Management and Prevention Division oversees the use, treatment and handling of hazardous and solid wastes. Conventional wastewater treatment with primary and secondary treatment processes efficiently remove microplastics (MPs) from the wastewater.
