亚游集团官方Pure water equipment needs to be cleaned and maintained regularly to prolong the service life of the equipment and provide you with the following suggestions:
亚游集团官方1. More complex water purification equipment, such as reverse osmosis water purification equipment systems, can be entrusted to the manufacturer for maintenance every three months to half a year. When repairing or replacing filter consumables by yourself, when removing the pipeline or parts, you can first Make a mark to ensure that you can connect to the correct position when reconnecting.
2. Backwashing of the pretreatment system. This work requires the customer to clean it by himself. If it is not available, it will be fully automatic backwashing when customizing the equipment.
3. The reverse osmosis membrane of the deactivated pure water equipment should be washed under low pressure regularly, especially in summer, it should be washed once every shift. If the shutdown time is more than 7 days, 0.5 to 1 sodium bisulfite or 0.5 to 1 formaldehyde solution should be used to protect the reverse osmosis membrane of purified water equipment. The pH and concentration of the protective solution should be detected in time.
4. The mechanical filters of pure water equipment are regularly backwashed. Compressed air and gas are rubbed during backwashing. After passing the backwashing, leave it for about 10 minutes and then wash it forward. The water from the frontwashing can be put into use after passing. Do not bring air into the reverse osmosis membrane. Without affecting the SDI value, prolong the running time of the mechanical filter of the purified water equipment as much as possible. This not only reduces the impact of switching the filter on the quality of the effluent water, but also saves a lot of backwash water.
5. Pure water equipment uses physical principles to implement cleaning. A simple physical cleaning method is to wash the membrane with low pressure and high flow rate through water for 30 minutes. This can restore the membrane's water permeability to a certain degree, but the water permeability is still long. It can also be used to rinse the membrane surface for 15 minutes under low pressure by using a mixed flow of water and air.
6, reverse osmosis membrane cleaning, citric acid solution, under high or low pressure, 1-2% citric acid aqueous solution for continuous or cyclic washing of the membrane, this method has a good pollution of Fe (OH) 3 Cleaning effect, pure water equipment This method is particularly effective for pollution. Water-soluble * liquid, pure water equipment is very useful for cleaning membranes contaminated by oil and iron oxide *, usually 30-60 minutes.
