The CWT technology

The CWT proprietary technology generates ultrapure water (UPW) even from the most difficult water feed. It works by harnessing the principle of thermal pervaporation in format suited for mass production and use in an industrial environment.

The process of thermal pervaporation takes place in a multilayer cell where warm water is fed into the cell. Individual pure water molecules escape from the surface of the water and make their way to the cool side of the cell. It’s cooled by a feed of cold water and the molecules condenses and water free from particles is tapped from the cell. In essence, we are lifting out pure water rather than filtering out impurities.

The approach produces a UPW pure from any non-volatile substances.

The consistently repeatable process is built into a system which can be scaled to any capacity. Multiple cells make up a module and multiple modules make up a stack. Each stack produces 500 liters of UPW per hour.

A commercially viable green transition is CWT’s main focus. As the technology concentrates pollutants and other valuable minerals, a zero liquid discharge can be achieved. Additionally, coupled with waste heat from industrial processes, the production cost of ultrapure water is lower compared to other common water purification solutions.
