If there are significant changes in the quality of the raw water supplied to the ultra-pure water system, softening or other treatment methods may be necessary. 2. Pre-treatment: Check whether the sand and carbon filters used in the pre-treatment process need to be backwashed. It is also necessary to determine whether the carbon in the activated carbon filters has lost its effectiveness, and if so, whether replacement is required. 3. Chemically clean the RO membranes in the ultra-pure water system or replace them, as well as replace the filters in the safety filters. 4. Conduct regular maintenance on the ultra-pure water system. 5. Consult the manufacturer of the equipment – they have a better understanding of the entire system and offer extensive technical support, which can help resolve issues related to high conductivity quickly.
