Practical instructions for the pre-filter of the water purifier-【3M filter element】

At present, there are various brands of water purifiers on the market. If you look closely at the description of the water purifier, you always see the words microfiltration, nanofiltration, ultrafiltration, and reverse osmosis. Remind the public not to let all kinds of 'filters' confuse their heads, and to recognize the scientific concept of water purifier consumption. u003cbru003e　　 When operating the water purifier, we should pay attention to the following problems u003cbru003e　　 1. In addition to the type of water purifier filter element, no matter what kind of water purifier you choose, there are specific operating requirements, and you must operate in accordance with the operating specifications. u003cbru003e　　2. Pay attention to the normal working pressure of the water purifier during operation, and also pay attention to the rated pressure during safe work. Be careful not to exceed it, otherwise it may affect the water purification effect. u003cbru003e　　3. Adding a proper amount of medicine to the water purifier can maintain the normal operation of the water purifier, and also guarantee the quality of the water. The dosage can be controlled and adjusted according to the turbidity of the water, and strive to achieve a better water purification effect . u003cbru003e　　4. The backflush of the water purifier can be controlled according to the turbidity of the effluent, and the backflush of the water purifier can also be carried out regularly, and it must be carefully cleaned during the flushing process. u003cbru003e　　5. The sedimentation area of u200bu200bthe water purifier should be discharged regularly. The sludge discharge cycle can be adjusted according to the turbidity change of the effluent. Pay more attention to the sludge discharge process to ensure the quality of purified water. u003cbru003e　　 6. Strictly manage the chlorination and disinfection equipment of the water purifier, because it is an indispensable supporting equipment for the water purifier. u003cbru003e　　 7. If you find that the water purifier is malfunctioning, you must solve the malfunction of the water purifier in time to ensure normal use. u003cbru003e　　 pre-filter and its main function u003cbru003e　　 In order to kill bacteria, we usually use boiling method, but this method can not get rid of insoluble solid impurities and harmful chemicals, such as rust, sand, free residual chlorine and Its compound chloroform (carcinogen). The pre-filter is a reliable impurity filtering device, which can filter out particulate impurities above 40-90 microns and restore the water quality to the standard when the tap water is shipped. u003cbru003e　　The pre-filter is a device for filtering the household water supply system. The filter is generally installed at the water inlet of the system. Because of its powerful filtering function, it can prevent secondary pollution of the drinking water system. Usually, a pre-filter is installed after the user's water meter to protect the safe and clean downstream pipelines and equipment of the system. It not only provides filtered clean water for downstream, but also fully protects the entire water system and the equipment on the system. u003cbru003e　　The main function of the pre-filter is to intercept coarse particles of impurities, sand and rust that are harmful to household water pipes and wading equipment in the water. When these foreign particles enter the water pipe, the water pipe and the wading equipment (such as washing machine, dishwasher, water softener, water purifier, water heater, etc.) installed on the water pipe may be damaged or even destroyed. Valves, connecting pipes and filters in the wading system will therefore need to be replaced. u003cbru003e　　 can be installed and used at home, and also suitable for independent devices upstream of the following equipment or systems, which play a positive protective role, such as: water purifier, dishwasher, coffee machine, water heater, boiler, washing machine, floor heating, heat dissipation Irrigation (such as micro-irrigation, drip irrigation system), etc., for tablets, central air-conditioning, cooling towers, motors, hospitals, and home gardens. It can prevent water pollution and avoid pipeline corrosion.
