ACT

About This Project

Every day, 2 million tons of sewage and industrial and agricultural waste are discharged into the world’s waters. These pollutants come from urbanization, industrialization, unsustainable food production practices, and poor water and wastewater management strategies. Waste Water Treatment Plants (WWTPs) are one of the most expensive public factories due to exceptionally high energy consumption. Although the EU has made waste water treatment obligatory for cities and towns within the EU-27 (Water Framework Directive (WFD) 91/271/CEE), little has been done to tackle the unsustainable 15,021 GWh of energy these plants consume per year.

 

The ACT aeration system utilises less energy than any known aeration technology. The technology makes use of new methods based on hydrodynamic supercavitation to efficiently mix gas (air containing oxygen) and liquid (treated wastewater). This new technology is versatile and can be adapted to meet the aeration needs of almost any type of WWTP. Additionally, due to the nature of the hydrodynamic process there is little equipment wear and tear because the imploding bubbles do not have direct contact with the solid surface of the equipment causing potential damage.

 

The aeration process does not require air blowers/compressors, air distribution piping, diffusers installation construction and pipes, which dramatically reduces the cost of an aeration system by a factor of 3-5 times.
