ABSTRACT:
A process wastewater treatment plant, and a process relating thereto, which converts process wastewater generated in battery manufacturing and the like into clean process water and sodium sulfate salt by treating the process wastewater to remove impurities and contaminants, including debris, oil/grease, heavy metal oxides, lead and other heavy metals, suspended solids, bacteria, organic compounds, and/or gases, from the wastewater to obtain a clean neutral sodium sulfate brine, subjecting the brine to heat to obtain distilled water and sodium sulfate salt, and purifying the distilled water by reverse osmosis for reuse as clear process water.
