| Abstract: | Pilot study on micro-flocculation/deep bed direct filtration process with the addition of polyaluminum chloride (PAC) was made in accordance with the quality of low turbidity water in Beijing No. 9 Water Supply Plant. The study focused on the preference of bed height and homogeneous media with ultra size, and the optimal chemical and hydraulic parameters of direct filtration process, as well as the optimization of backwashing. All of these were compared with overall treatment efficiency and economic benefit in the existing water plant, and thus providing a basis for the practical application of micro-flocculation/deep bed filtration process. |
