The strong oxidant hydrogen peroxide or sodium hypochlorite should be used to clean the membrane in the process of papermaking wastewater treatment, and the most important thing for the organic membrane is to contact with the strong oxidant, and it is generally required to soak the organic membrane in 1% sodium bisulfite solution (reducing agent)
when it is shut down for more than 24 hours to prevent air oxidation; at the same time, the hydrophilicity of the ceramic membrane is also improved It is also stronger than most organic membranes, which ensures that the ceramic membrane has higher water permeability and permeation flux per unit area than organic membrane.
