摘要

Membrane-separation activated sludge process is one of the advanced wastewater treatment technologies. A serious problem bas been arising due to the fouling of the membrane. A pilot plant experiment was carried out to solve this prob- lem. The results of the investigation showed that in addition to the washing of membrane by aeration, back washing by chemicals was effective in preventing the fouling of membrane. But beyond a certain degree of membrane fouling, back washing was no longer effective.
