Study on Backwash of Biological Aerated Filter
View through CrossRef
Backwash was very important for ensuring the successful performance of biological aerated filter (BAF). Through the experiment, combined air-water backwash mode were taken in BAF backwash and water backwash were 5~7L/(m2·s) and air backwash 13~17L/(m2·s) with the backwash period 24h and the backwash time 15min. It took 5~6h to recover to the optimal performance after backwash.
