Humus Soil

A promising humus activated sludge process with microorganism cultivation reactor filled with humus soil pellets on the basis of traditional activated sludge technology was developed in Japan and used to improve sewage treatment efficiency. Since 1980s, humus activated sludge process was successfully applied in Shimauchi Housing Complex of Matsumoto City, Yamanouchi Sewage Treatment Center and Sewage Treatment Facility at Nagayoshi Agriculture Hamlet and was applied in more than 200 sewage treatment plants in Korea. The operating results showed that the process has the advantage of excellent pollutant removal performance and sludge dewaterability and no odor release.
