| Summary: | 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. |
