The daily work and maintenance of purified water production line equipment2018-06-30 09:28 Water quality safety is a topic that people have been discussing enthusiastically in recent years. In order to ensure the safety of drinking water, more and more people have given up tap water and put purified water As the main source of drinking water, the future of the pure water industry is bright, and there are more and more pure water plants on the market. However, as a pure water plant, you must fully understand the equipment, and you must have an in-depth understanding of how the Liaoning pure water production equipment works Daily management of this issue. In the daily management and maintenance of the purified water production line equipment, the user should pay attention to whether the equipment pipeline has water leakage, whether the daily inspection system can work normally, and record various data such as the equipment pressure gauge, inflow and outlet water conductance, flowmeter, etc., for future equipment Maintenance provides the basis for repair; in addition, if there is any abnormal situation, please contact our company. Activated carbon filtration is mainly used to remove the strong oxidant (residual chlorine) in the municipal disinfected water supply, which will cause irreversible damage to the softening resin and RO membrane. According to the operating conditions of the equipment, the activated carbon use time is preset in the controller system, which can be selected according to the actual use of the site, so as to reach the service life and prompt the user to replace the security filter to ensure that the RO membrane influent impurity particles are less than 2 microns, and it needs to be regular Replace the filter element. Because the actual water consumption varies greatly in various places, it is recommended to check the security filter element frequently during the early operation, and replace the filter element in time when the filter element becomes black, and at the same time accurately determine the filter element replacement cycle. Under normal use, the recommended filter element replacement cycle is 0.5-1 month Replace it once. In actual operation, the high-quality pH value is 6.5 to 7.5, and the temperature has a significant impact on the water permeability of RO. When the water temperature increases by 1 ℃, the water permeability increases by 2.7%, but the operating water temperature cannot exceed 35 ℃; The greater the permeable water volume (within the permitted range), the operating pressure is generally controlled within the range of 0.75 to 1.2 MPa; the recovery rate during operation is controlled to be 75%; when starting the pure water production equipment, the inlet valve should be opened slowly to prevent reverse osmosis membranes It is damaged due to momentary excessive pressure; attention should be paid to static back pressure during operation, and the pressure on the clean water side is not allowed to be higher than the pressure on the inlet water and concentrated brine side; no matter when it is running or shutting down, attention must be paid to prevent back pressure. Dehydration of the osmotic membrane, because once the reverse osmosis membrane is dehydrated, it will cause irreversible damage. When the RO equipment is out of service for more than 48 hours, the reverse osmosis membrane needs to be maintained to prevent the membrane from being damaged by the growth of bacteria and microorganisms. There are two types of maintenance fluids commonly used: sodium bisulfite or formaldehyde solution.
