Taking the filtration system composed of hydrocyclone and screen filter as study object,the performances of the system under high-silt content water,including variation of the local head loss,the relationship between local head loss and flow rate and silt separation efficiency,were studied through field simulation experiment.The results showed that in the design flow rate range,the local head loss of the system changed slowly then rapidly with running time,and after the local head loss of screen filter exce...
