Study on the Backwash Method of Biological Activated Carbon Filter
tract:Backwash is very important for ensuring the successful performance of biological activated carbon (BAC) filter and an experimental study on the comparison of va rious backwash methods‘ results was carried out.Based on the variation in turbid ity of backwash effluent and the impact of backwash methods on filter effluent q uality,the proper backwash method was determined and the related parameters such as backwash strength and period were recommended,so as to offer reference for t he design and operation of BAC filter.
