Close the concentrated water line to the fresh water and the polar water line by shutting down the inlet valve of the concentrated water.Cleaning procedures for EDI ultrapure water treatment equipmentCleaning procedure 1: cleaning and disinfection of concentrated water line.Cleaning procedure 2: cleaning and disinfection of fresh water pipeline.
Overview of ultra clean water EDI cleaning operation processIndependent cycle cleaning program1 、 evacuation cleaning system.2 if the direct cleaning method is used, the EDI system can not be evacuated before starting the cleaning or between the cleaning steps (if it has worked more than one step). If a recirculation cleaning method is used, the EDI system is evacuated before starting cleaning or during cleaning (if it has worked more than one step).
EDI water treatment module is an important part of the ultra pure water equipment, affect the purity of the water directly by ion water equipment EDI membrane module operation, so we must carry out regular maintenance on the EDI membrane block cleaning, to ensure the long-term stable operation of the equipment.
