Off-line cleaning and repairing method for different fouling of waste reverse osmosis membrane |
| abstract |
An off-line cleaning and repairing method for waste reverse osmosis membrane comprises the following steps: (1) analyzing the components of the fouling of the waste reverse osmosis membrane; (2) cleaning or repairing the membrane using acid or basic cleaning reagent and repairing reagent for different membrane fouling by using waste reverse osmosis cleaning and repairing equipment according to the analysis result; (3) continuously measuring the correlated parameter of the membrane performance in the chemic cleaning and repairing process. The parameters of the membrane cleaned and repaired by the method approaches those of the new membrane, the repairing ratio of the membrane is greatly increased and the pertinence of the method is improved, meanwhile the chemic damage by the existing cleaning methods is avoided. |
