Hollow fiber ultrafiltration membrane pollution refers to the amount and concentration of biological macromolecular substances such as liquid particles, colloidal solutions, organic compounds, microbial strains, etc. to be treated, and the physical and mechanical equipment effects of the membrane, resulting in adsorption on the membrane surface or membrane pores, and deposition makes the membrane pores. Shrinkage or blockage, resulting in a decrease in the water permeability or separation working capacity of the membrane. The causes of membrane fouling include the coverage pollution caused by the absorption of excess interception on the membrane surface and the inner wall of the microplate hole, the situation of colloidal solution in the membrane hole, and the concentration of biological macromolecular substances such as organic compounds and microbial strains.
(3) Cleaning on time. Uf system water treatment in operation can be cleaned regularly or manually according to the regularity of membrane fouling. For large and medium-sized equipment in industrial production, it should be cleaned on time according to the sequence of the automatic control system.
