With high potential in treatment capacity and application stated in the four previous sections, it could be commendable to introduce the self-purification sewer using by- product pervious concrete as media inward to the case of water sanitation and sewerage system in Vietnam. The treatment performance will be evaluated via lab- scaled sewer system. Hereby, this study is conducted to investigate the in-sewer treatment capacity of modified self-purification sewer. The specific objective of the study is described as follows. Objective of the thesis: To assess the self-purification capacity of domestic sewage for organic pollutants using pervious concretes as microbial attached media in terms of removal efficiency of organic pollutants and nitrogen. To achieve the above objective, I operated a bench scale in-sewer purification reactors with polluted canal water as the source of sewage. I prepared two types of pervious concrete materials, placed them in the bench scale reactor, and evaluated the removal performance of the COD, NH4-N and TN.
