During the application of ultrapure water equipment
During the application of ultrapure water equipment, the filter element of the ultra-pure water equipment precision filter should be regularly inspected and replaced in time to prevent the performance of the filter element from causing contamination of the reverse osmosis membrane particles. Generally, the filter element should be replaced when the differential pressure at the inlet of the precision filter is greater than 0.15mpa. Generally check once a month and replace the filter element every 2 to 3 months. During operation, it is also necessary to frequently check whether there is gas in the precision filter, and air cannot be brought into the reverse osmosis membrane. For spare or long-term outage precision filters, formaldehyde protection methods should be adopted to prevent bacteria from multiplying.
