Simple Wastewater Treatment System for Cafeteria

Wastewater is generally viewed as a negative resource, both from an aesthetic perspective due to its characteristically bad odor, and from the fact that it's a main component is human generated waste. A greater importance, considering the need for treatment, is the fact that untreated wastewater discharged into a natural water body and open environment constitutes a great hazard for the environment and a health risk for human and animal lives. This research enables to identify the suitable hydraulic retention time for activated sludge process with maximum pollutant removal. Also this helps to determine the efficiency of activated sludge method and floating macrophyte constructed wetland on wastewater treatment for cafeteriäs wastewater.
