A study was conducted by an environmental engineering firm to design a suitable treatment system for the groundwater currently used as the potable water supply for DVI. Reverse Osmosis (RO) was determined to be an effective technology in meeting the applicable standards for water quality. The RO system would remove total dissolved solids (TDS), iron, and manganese from the brackish groundwater originating from wells that supply DVI.
However, the quantity of concentrate from the RO system posed a challenge to minimize the impact of this stream. It was determined that a Zero Liquid Discharge (ZLD) system was the only acceptable option to successfully meet the mandates regarding the elimination of system wastewater effluents.
