EVAPX® (Low Energy Evaporation and Crystallisation)

EVAPX™

Low Energy Evaporation and Crystallisation

EVAPX™ is an evaporation and crystallisation technology which uses dry air to evaporate waste water, resembling water’s natural evaporation into the atmosphere.

PRODUCES HIGH QUALITY EFFLUENT WATER
LOW TEMPERATURE EVAPORATION
TRUE ZERO LIQUID DISCHARGE
LOW OPERATING COST

Summary

EVAPX™ is an evaporation and crystallisation technology which uses dry air to evaporate waste water. The dry air stream allows evaporation to occur at temperatures lower than boiling point and at atmospheric pressure, reducing the costs associated with heating and pressure vessels.

 

Our EVAPX™ technology is an efficient way to achieve zero or minimum liquid discharge (ZLD/MLD), increasing recoveries and reducing waste. Highly concentrated and saline (>5%) waste streams can be evaporated using the technology without scaling/fouling, leaving behind semi-dry salts. The evaporated water and heat energy are then recovered in the dehumidification chamber. EVAPX™ can be powered by electricity, steam, waste heat or solar energy.

Process Description

Water enters the evaporation chamber where is evaporated using the dry air stream. The solids settle at the bottom of the evaporation chamber and are separated out. The humidified air moves to the condensation chamber where it condenses as distilled water, and the heat is recovered.
