Municipal sludge characteristic changes under different aerating condition in a deep-shaft aeration system
A pilot-scale municipal sewage sludge deep-shaft aeration system was implemented in Lanzhou, Gansu Province of China. The reactor depth was 60 m with a diameter of 1.0 m and the sludge to be treated came from a wastewater plant in Lanzhou. In order to obtain the optimum operation conditions, analysis was conducted on the transformations of the volatile suspended solids (VSS), temperature, pH, ...

Treatment of municipal sewage by Biological Aerated Filter (BAF) using burned clay pellet as media
The high-strength municipal sewage was treated by the two-stage Biological Aerated Filter (BAF) pilot system with microorganism carrier of burned clay pellet. The effects of hydraulic loading rate, aeration ratio, overloading, backwashing and the height of media on the performance of BAF were investigated. In higher hydraulic loading and lower ratio of aeration, the two-stage BAF may decrease ...
