| Research Abstract |
Curtain type DHS(Down-flow Hanging Sponge) reactor has been studied for sewage treatment in developing countries, which was not expected to produce a good water quality applicable for developed countries. However, even though DHS is very cost effective and energy saving process, it was revealed that a system of UASB and DHS had a good effluent comparable to activated sludge process with less sludge production. In this study, novel DHS reactor for developed countries like Japan was tried to develop by transferring the knowhow accumulated in sewage treatment experiments in India.
