The water quality characteristics of Queshan reservoir (Jinan,China), which derived from Yellow River, were low temperature and low turbidity. Based on those characteristics, the flofilter, which joined flotation with filtration, was designed, and it has many advantages, such as less area, no flocculation tank, flexible operation, coordinated water purification of flotation and filtration, etc. Through the optimum study on flocculation conditions, PAFC was suited for Queshan reservoir water, and the optimum dosage of PAFC was 2.0 mg Al3+/L. In the conditions of low temperature and low turbidity, the filtration cycle was 72 hours, and the average removal efficiency of turbidity, CODMn, UV254, chroma were 86.49%, 43.46%, 63.51%, 75% respectively in the early running, and the flofilter showed higher water purification effect.
