There are many methods for health management without using the traditional sewage treatment system. One method is to use the decentralized sewage treatment system to treat and dispose the sewage where the water source appears, instead of transporting it to the central treatment center. Decentralized sewage treatment system can include sewage treatment tank, aeration treatment unit and constructed wetland, which uses bacteria, plants and other natural processes to decompose and eliminate pollutants in sewage. Another method is to use dry sewage processor, which does not need to purify water and can be used in areas without sewage treatment system. There are several types of dry sewage processors, including the usual use of microorganisms to decompose waste and convert it into waste.
