Difference between sampling device and filter of water quality instrument The difference between the two:The filter just removes some granular objects.Water purifiers are harmful substances such as some heavy metal ions in the water through certain chemical or adsorption.The filter is an indispensable device on the conveying medium pipeline, usually installed in the pressure reducing valve, pressure relief valve, fixed water level valve, and the imported equipment of other equipment of the square filter. After the filter cartridge with a certain size filter screen, its impurities are blocked. when cleaning is needed, just remove the removable filter cartridge and reload it after processing. Therefore, it is extremely convenient to use and maintain.The water purifier is also called water purifier and water filter. The core technology of the water purifier is the filter membrane in the filter element device. The main technology of the water purifier comes from the UF membrane and RO reverse osmosis membrane

What is the central water purification front filter? The front can only solve the pollutants of large particles (20-40 microns), such as sediment, colloid, some red worms, etc. The filtration accuracy is not high, and it is impossible to improve the taste of water and remove harmful substances such as bacterial viruses. The advantage is that the service life is long (it can be washed regularly) and the price is cheap. it can protect the filter element for the water purifier installed behind and prolong the service life of the water purifier filter element. Therefore, it is generally used as a water purifier.If the turbidity of your tap water is very high, this filtration can effectively reduce pollutants. if you are safe, of course, you must install a water purifier, not just a front. The two complement each other, not substitute. Generally refers to the coarse filtering of the first level. The front is dedicated to filtering impurities of large particles such as sediment, and the effect is relatively primar
