Sharing Wastewater Solutions Aqana is a company in wastewater treatment. We developed in the last 8 years an anaerobic treatment technology. This technology is based on biomass on carrier. An anaerobic process is a beautiful and simple natural occurrence. With the absence of oxygen waste is converted to biogas and only a small amount of sludge. But as in most cases, a human synthesis of a natural process ends up very complicated. Aqana takes advantage of the bacterial property to attach to surfaces. The anaerobic bacteria are grown on a floating carrier. With this Aqana makes the difference. By using a floating carrier bed the reactor design is that simple that it fits in any tank. Three concepts are the product of the research and collaboration with launching customers.
