Zero Liquid Discharge


Our unparalleled depth of experience in ZLD encompasses more than 160 ZLD installations, including stand-alone thermal / evaporative processes, membrane processes, or hybrid systems, which Aquatech pioneered. Hybrid ZLD systems result in greater value, ease of operation and reduced operating costs.
