How to clean some accessories in reverse osmosis equipment?
Many accessories in reverse osmosis equipment need to be cleaned in time, otherwise, it will have an adverse impact on the operation of reverse osmosis equipment. Today, Volardda Editor will share with you the cleaning of these accessories in reverse osmosis equipment. Cleaning mainly consists of cleaning water tank, cleaning water pump, and precision filter (of course, there is also the most important cleaning of reverse osmosis membrane, which Volardda Editor also shared with you before, you can check it out). When our reverse osmosis host system is polluted and the effluent index cannot meet the requirements, we need to clean the reverse osmosis equipment effectively in time to restore its unique efficacy.
Reverse osmosis technology has been widely used because of its special advantages. The cleaning problem of reverse osmosis equipment may also cause unnecessary losses to many users with weak technical strength. Therefore, by doing a good job in the management of reverse osmosis equipment cleaning, perhaps, serious problems can be avoided.
the cleaning method:
*First, low pressure flushing reverse osmosis equipment
Regularly flushing the reverse osmosis equipment with large flow, low pressure and low pH value is beneficial to peel off the dirt attached to the membrane surface and maintain the membrane performance, or when the reverse osmosis equipment enters the water SDI (Silting Density Index, referred to as Silting Density Index, referred to as Silting Density Index, for short When SDI) suddenly rises above 5.5, low-pressure flushing should be performed, and the machine should be turned on after the SDI value is adjusted to pass.
*Second, reverse osmosis equipment outage protection
Due to fluctuations in production, reverse osmosis equipment inevitably has to be shut down frequently, and protective measures must be taken during short-term or long-term shutdowns. Improper handling will lead to degraded and irrecoverable membrane performance. Short-term storage is suitable for systems that are out of operation for less than 15 days, and the reverse osmosis equipment can be protected by low-pressure flushing every 1 to 3 days. Practice has found that when the water temperature is above 20 °C, the water in the reverse osmosis equipment will stink and deteriorate after being stored for 3 days, and a large number of bacteria will multiply. Therefore, it is recommended that when the water temperature is higher than 20°C, low-pressure flushing is performed once every 2d or 1d. When the water temperature is lower than 20°C, low-pressure flushing can be performed once every 3d. After each flushing, all inlet and outlet valves on the reverse osmosis device of the water purification equipment should be closed. . Long-term deactivation protection is suitable for systems that have been out of operation for more than 15 days. At this time, protective liquid (bactericide) must be filled into the reverse osmosis device of the water purification equipment for protection. The commonly used bactericide formula (composite film) is formaldehyde 10 (mass fraction), isothiazolinone 20 mg/L, and sodium bisulfite 1 (mass fraction).
