How to maintain and clean reverse osmosis pure water equipment
Release time:2024-04-19
After the pure water equipment is put into use for a period of time, maintenance and upkeep of the equipment should be carried out, consumables should be replaced, abnormal operation of the equipment should be detected, and then how long and how to maintain it may not be clear to most users. Next, Suzhou Shuoke Water Treatment Equipment will discuss how to maintain purified water equipment after it is put into use. According to the water quality of the raw water, replace the filter element of the safety filter every 30 days. The cleaning cycle of the sand filter is 15-20 days, with a backwash time of 5-10 minutes and a forward wash time of 5-10 minutes, and a lifespan of 2 years; The cleaning cycle of the carbon filter is 15-20 days, with a backwash time of 5-10 minutes and a forward wash time of 5-10 minutes, and a lifespan of 1 year. If the previous treatment runs normally and the water quality of the RO membrane in the purified water equipment device meets the requirements, and the device is maintained according to the operation method, the service life of the membrane can reach 2-3 years. However, due to the formation of pollutants such as scale and bacteria, the water output and quality will gradually decrease.
If the production gradually decreases by 15% due to factors such as temperature and pressure, the Suzhou Shuoke reverse osmosis pure water equipment indicates the need for chemical cleaning of the reverse osmosis membrane; The temperature at the installation location of the purified water equipment should be between 4~45 ℃. When the equipment is shut down for a long time, protective liquid should be added to the system. The initial addition of protective liquid should be done by professionals or under professional guidance. During the use of purified water equipment, occasional malfunctions and problems may occur due to various reasons. After a malfunction occurs, it is necessary to carefully check the operation records, analyze the cause of the malfunction, and analyze, judge, and troubleshoot according to electrical faults and treatment methods. Due to the frequent continuous production operations of enterprises, reverse osmosis equipment inevitably needs to be shut down for maintenance, and maintenance measures need to be taken for both long and short periods of downtime. Improper treatment of Suzhou Shuoke water treatment equipment can lead to a decline in membrane function. For systems that have been out of service for less than 15 days, short-term retention is recommended, and low-pressure flushing can be used every 1-3 days to maintain the reverse osmosis equipment. So when the water temperature is above 20 ℃, it can be washed clean every 2 days or 1 day. When the water temperature is below 20 ℃, it can be cleaned every 3 days. After each cleaning, all inlet and outlet valves of the clean water reverse osmosis equipment need to be closed.
Long term water outage maintenance is applicable to systems that have been without water maintenance for more than 15 days. At this time, maintenance fluid (disinfectant) must be used to add water to the water supply equipment for maintenance. The common disinfectant formula for isothiazolinone deionized water equipment is formaldehyde 10 and sodium bisulfite. In general, cleaning should be carried out once every 2 to 10 months. Assuming that cleaning is necessary every month, this 20mg/L is the pre-treatment system that needs to be improved and the operating parameters adjusted. Assuming that cleaning is required once every 1-2 months, does it make it more difficult to improve the pre-processing system as the demand increases the operational level of the equipment? In general, reverse osmosis equipment membranes are contaminated by inorganic scale, colloids, microorganisms, metal oxides, and other substances. These substances deposit on the membrane surface, causing a decrease in the output or desalination rate of the clean water reverse osmosis equipment, an increase in pressure difference, and even irreversible damage to the membrane. Therefore, in order to achieve good permeability and desalination function, desalination equipment needs to perform chemical maintenance and cleaning on the membrane. Reverse osmosis equipment is often subjected to high flow, low pressure, and low pH flushing, which is beneficial for removing dust attached to the membrane surface and maintaining membrane function. Alternatively, when the inlet SDI of the reverse osmosis equipment increases by more than 5.5, low-pressure scrubbing should be performed until the SDI value is adjusted to be qualified before operation.
