To address intake and discharge volume limitations, O'Brien & Gere's holistic approach met stringent government regulations. The system managed domestic, process, utility, and wastewaters to maximize water recycle benefits. For example, general wastewater was treated and used as feed water in the high purity water (10 M) treatment system, and acid wastewater was used for cooling tower and scrubber make-up water. The strategy aimed to reduce overall site usage by 50%, and discharge by 60%. By incorporating advanced recycle systems, O'Brien & Gere assisted the client in meeting government requirements by using only half the water, which also allowed the plant to meet anticipated production requirements.
