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.

帘式DHS（下流式悬挂海绵）反应器已在发展中国家的污水处理中进行了研究，预计不会产生适用于发达国家的良好水质。然而，尽管 DHS 是一种非常具有成本效益和节能的工艺，但据研究表明，UASB 和 DHS 系统的出水效果与活性污泥工艺相当，且污泥产量较少。在这项研究中，尝试通过转让印度污水处理实验中积累的技术知识，为日本等发达国家开发新型DHS反应器。
