Aquatech International, a global specialist in water and wastewater technologies for the industrial and infrastructure markets, has developed LoWattT, an energy-efficient seawater reverse osmosis (RO) system designed for higher reliability and optimal energy consumption - up to 25 percent less than conventional SWRO.
The patented LoWatt process addresses two key concerns with membrane systems - biofouling and energy consumption - by combining robust pretreatment, an innovative cleaning mechanism and optimized RO plant design to deliver the lowest cost of water. LoWatt integrates UF membrane pretreatment and a nutrient removal step while continuously deactivating bacteria without using any chemicals to mitigate biofouling.
It also uses a chemical-free, online cleaning and flushing process that minimizes cleaning cycles and increases plant availability. The LoWatt system results in lower life cycle costs by solving the always-difficult issue of biofouling resulting from the presence of complex organics and bacteria in the seawater. LoWatt designs have been implemented in desalination facilities in the Middle East and other parts of the world.
Aquatech is headquartered in the United States, and has a significant presence worldwide through subsidiaries in India, Europe, the Middle East, and China. The company strives to provide technology leadership and performance excellence to the global water industry, and aims to support its clients with cutting-edge sustainable solutions, minimizing their life cycle cost, as well as their carbon and water footprint.
