Abstract

Along with the population increasing as well as the development of socio-economic, the demand for water concussion was increased leads to the increasing of domestic wastewater, potentially causing environmental pollution if have no treatment solution before discharging into the receiving source. Currently, there are many technological solutions applied to treat domestic wastewater, including: natural treatment solution that is cheap but requires a lot of space (ponds, lakes, wetland, etc.), expensive but has high treatment efficiency but less construction area (Aerotank, MBR, JOHKASOU...), and semi-natural treatment technologies combine biological treatment processes (anaerobic, aerobic) to limit the disadvantages and using advantages of two above mentioned technological solutions. This paper presents the results of research on selection of scale and basic parameters of modules using suitable anaerobic and aerobic biological treatment solutions for domestic wastewater treatment.
