How to prevent the requirements of EDI damage to the automatic reverse osmosis pure water equipment system? Author: automatic reverse osmosis water equipment system from its invention, instead of the traditional ion exchange water treatment technology has reached the modern industrial and environmental needs, so when automatic reverse osmosis water equipment EDI system problems and damage The current situation will affect the normal production of the company and increase the company's operating costs. 1. The EDI membrane block runs under the condition of high current and lower than the rated flow for a long time, and the heat accumulated on the side of the electrode plate cannot be effectively dissipated, causing the diaphragm and the screen of the EDI close to the two poles to heat and deform first, and the EDI concentrated water pressure difference increases. , Water quality and water volume decline, and water leakage will be severely carbonized.  2. The EDI membrane block has not been cleaned and maintained for a long time. The EDI membrane and channel are fouled, and the pressure difference between the inlet and outlet water increases, which causes the quality of the produced water to drop, the current cannot be adjusted, and the voltage rises.  3. The ultrafiltration system controls the residual chlorine and other oxidants improperly, and the EDI oxidant is excessively introduced, which causes the EDI resin to break, block the water production channel, and reduce the water volume.  4. The use of improper cleaning and disinfection directly causes the EDI resin to break, and the pressure difference between the inlet and outlet water increases, resulting in a decrease in the quality and volume of the water produced.  5. When the EDI system is running manually, it is powered on under water shortage, which directly causes the heating and carbonization of the diaphragm and resin, and the cleaning is ineffective and cannot be used.  6. u200bu200bThere is no security filter before the EDI water enters, or the pipes and water tanks are not cleaned during installation, which causes foreign objects to block the EDI channel and increase the pressure difference between the inlet and outlet water, resulting in a serious drop in the water production and ineffective cleaning.  7, the current and voltage exceed the rated value or human error operation.   8. The system process design is improper and does not meet the EDI use conditions.  9. Improper system maintenance and management, and failure to comply with EDI conditions of use.
