Definition   Solar Aquatics is a concept developed by marine biologist John Todd and licensed by Ecological Engineering Associates (EEA). Where traditional forms of wastewater treatment use a combination of biological, physical and chemical treatments, solar aquatics relies more heavily on biological processes to treat wastewater. It uses plants and animals to create a microenvironment that is symbiotic with the same kind of bacteria used in more traditional methods. The plants, animals and bacteria work together to break up sewage. Leafy plants help remove larger elements out of the wastewater, thereby reducing the size needed to house a wastewater treatment plant. Because the entire system is housed within a greenhouse, it also reduces the smell and noise pollution associated with more traditional treatment facilities. The outflow from a solar aquatic system is equal to or better than that coming from a traditional wastewater treatment facility.
