(1)Check water box, pipeline and filter, change the filter material if needed.

(2)Input q.v. RO effluence to water box.

(3)Input q.v. IR-260 to water box, mix the solution with water pump, measure pH.

(4)Clean the system repeatedly, measure pH 5-20 minutes. After pH rise to 4, input q.v. IR-260 or acid, till pH not rise, meaning cleaning is end.

(5)If pollution is serious, sometimes the first batch detergent should be evacuated and the next batch should be required.

(6)Pay attention to solution temperature, don’t exceed the required temperature .


25kg per barrel.

Safety and Protection:
