The automation level of purified water equipment is very high, with precise design and compact structure, suitable for use by large industrial enterprises. The equipment is developed using reverse osmosis technology, and the cost of reverse osmosis membranes is high. Therefore, proper maintenance and upkeep of water purification equipment can avoid potential hazards. Next, let's introduce the correct maintenance and upkeep methods for water purification equipment.

The total water inflow of the reverse osmosis equipment is controlled by the RO inlet regulating valve. If the water inflow of the reverse osmosis equipment does not change, do not tamper with the RO inlet regulating valve, and it is strictly prohibited to fully open or close it; The RO concentrated discharge regulating valve is used to adjust the system recovery rate. If the recovery rate does not change, do not tamper with the concentrated discharge regulating valve, and do not fully open or close it.

Clean water equipment filters are regularly backwashed. During backwashing, compressed air gas friction should be carried out. After the backwashing is qualified, it should be left to stand for about 10 minutes before washing. Only after the washing water is qualified can it be put into use. Do not bring air into the reverse osmosis membrane.

When a high and low pressure alarm occurs in the reverse osmosis equipment, first check whether the manual valve opening between the security filter and the high-pressure pump is too small, then check whether the RO inlet control valve and concentration discharge valve are normal, and then press the high and low pressure alarm reset button to restart the equipment.

Regularly inspect and replace the precision filter element in a timely manner to prevent particle contamination of the reverse osmosis membrane of pure water equipment caused by leakage of the filter element due to installation or quality issues.

Operating pressure control should take the lowest possible pressure value while meeting the requirements of water production and quality, which is beneficial for reducing the water flux attenuation of the membrane and reducing the replacement rate of the membrane.

The concentration of water should be adjusted in a timely manner to maintain a recovery rate of around 75. The concentration of slightly soluble salts in the concentrated water should not exceed the solubility product and scale, and water should not be wasted, achieving economic operation.

Emission control: Due to changes in water temperature, operating pressure, and other factors, the water production of the device also changes accordingly. At this time, the emission should be adjusted, otherwise it will affect the desalination rate of the device.

The device shall not be shut down for a long time and shall operate for at least 2 hours per day. If it is ready to shut down for more than 72 hours, a chemical cleaning device shall be used to fill the components with 1% sodium bisulfite and 18% glycerol for protection.

Compared with the initial operating state, when the water production of the standardized water purification equipment reverse osmosis device decreases by 10%, or the salt content of the produced water significantly increases under specific conditions, or the pressure difference increases by 15, the reverse osmosis membrane should be cleaned in a timely manner.
