What are the precautions for the use of food deionized water equipment? Author of the article: 1, regular inspection to check the filter regularly filter industrial water equipment long run, in accordance with the provisions of regular replacement, so that it can ensure water quality equipment. If the equipment is used continuously for several months, pure water can be discharged according to the actual situation, and it can also play a certain role in cleaning the equipment. 2. Establish an independent water supply system. Large-scale industrial pure water equipment using tap water as the source of water is best to set up an independent water supply system, which can ensure the stable operation of the water supply system and reduce the impact on the water supply network of the whole plant when the RO system starts and stops. The momentary impact. When the RO device draws water directly from the raw water pipe network, high and low pressure protection facilities should be installed, because most of the tap water pipe network pressure fluctuates greatly. 3. Correct addition of medicaments When adding medicaments, the compatibility between the medicament and the medicament should be considered first, and then the compatibility between the medicament and the membrane material should be considered. For example, coagulants, coagulants, bactericides, reducing agents and scale inhibitors are often used in RO systems at the same time. Since limbs in natural water are generally negatively charged, positively charged cationic coagulants are usually used. In order to prevent scaling of the RO device, almost all measures of adding scale inhibitors are considered at the water inlet of the RO, and these scale inhibitors are almost all negatively charged. Therefore, the cationic coagulant should be avoided to react with anionic scale inhibitors to prevent the colloidal compounds generated by the reaction from depositing on the membrane surface.
