Rotating contactor + Floating wetlands
Rotating biological contactors are wastewater treatment systems in which microorganisms are attached to a material which rotates semi-submerged in the wastewater. These systems are an alternative to conventional active sludge. Microorganisms in the material make use of the organic matter in the wastewater and take the oxygen needed from the atmosphere when the disc is outside the water. That way there is a reduction in the energy and economic demands compared to those systems that requires mechanical air injection.
Effluent from this system will be introduced to a floating wetland, creating a hybrid system with both technologies, finding a new approach to wastewater treatment in small communities.
