The Indiantown Cogeneration Plant has recently modified their zero liquid discharge scheme to incorporate membranes to treat the blowdown from their cooling tower. This was originally sent to two brine concentrators. The plant required the flexibility to use any combination of makeup water. It was also desirable to replace the brine concentrators due to corrosion and to achieve savings in power. The integrated membrane system (microfiltration and reverse osmosis) was commissioned in 2011. It allowed the brine concentrators to be replaced and generates high-quality permeate for boiler feed while maintaining zero liquid discharge.
