ORGANIC AND HYDRAULIC SHOCK LOADINGS ON A BIOLOGICAL AERATED FILTER

摘要

The performance of a biological aerated filter (BAF) during short-term (60 min) organic and hydraulic shock loads was investigated. The BAF used for the present experiment was not capable of absorbing high peak organic shock loads when the organic loads were increased from a normal load of 1.2-1.4 kg soluble chemical oxygen demand (sCOD) m~- d~-1 to shock loads between 5.1-7.3 kg sCOD m~-3 d~-1, based on empty bed volumes.
