Zero Liquid Discharge Technology (ZLD)
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 (ZLD) help you achieve environmental compliance, reduce your carbon footprint, and recover high purity water for reuse. Our proven zero liquid discharge 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.
Hybrid ZLD: An integrated automated system incorporating a membrane pre-concentrator or HEROTM technology, followed by the thermal/evaporative Zero Liquid Discharge technologies below.
- Vertical tube falling film evaporators
- Seeded slurry (brine concentrators)
- Non-seeded evaporators
- Forced circulation crystallizers
- Sludge dewatering
- Filter press
- Drum dryers
