【Objective】The purpose of this paper is to study the head loss across the torpedo screen filter and the associated filtration time.【Method】Experiments was carried out using a muddy water at constant sediment content and constant flow.【Result】Under constant sediment content, the time it took the head loss to stabilize increased as the flow rate increased from 240 m3/h to 300 m3/h, while decreased for flow rate between 300~360 m3/h. Under constant flow condition, the time it took the pressure drop to reach △p=0.10 MPa decreased as the sediment content increased. With the change in filtration time, the head loss experienced three different stages: remaining constant, gradually decreasing followed by a sharp rise.【Conclusion】Torpedo plays an important role in prolonging the filtration time, and the appropriate preset pressure for the torpedo screen filter was 0.04 MPa.
