The AWFD® (Air Waterfall Device) is a device created and patented by our founder, João Mariz.
With its Venturi Effect property, the AWFD® provides aeration that is completely different from other more common aerators on the market, injecting micro-nano bubbles into the effluent to be treated, guaranteeing a concentration and quality of aeration like no other solution.
This solution, implemented in several sites in Portugal and Brazil, shows that the aeration provided by the AWFD® promotes the removal of organic loads of up to 85%.
