Zero Liquid Discharge (ZLD)
Green Technology, YES. Dirty Planet, NO.
Whether to meet regulations – for difficult to-treat wastewaters – or for situations where scarcity of water demands water recovery (recycle/reuse) – Aquatech’s innovative Zero Liquid Discharge technologies help you achieve environmental compliance, reduce your carbon footprint, and recover high purity water for reuse. Our proven ZLD technology eliminates liquid waste by converting it into disposable dry solids. Aquatech offers integrated, site-specific ZLD solutions, which are based on standalone thermal/evaporative processes, membrane processes, or a combination of the two, namely hybrid systems.
- Cooling tower blowdown
