This sewage treatment plant is made up of four chambers which are connected together. The first chamber has an air pump which will suck out the air inside the tank. This will make sure that there is no oxygen left inside the tank. Then, the next chamber will be filled with water. After that, the third chamber will be filled with activated carbon. Finally, the fourth chamber will have a filter system which will remove any impurities from the water.
