How to choose water purifier with ultrafiltration membrane filter - 【 3 m filter.

At present, various types of ultrafiltration membrane water purifier on the market, different filtering methods. In use process need to be replaced periodically filter, how to choose the ultrafiltration membrane filter also became a problem for everyone. Ultrafiltration membrane filter select

first of all, you need to know the replacement cycle filter replacement. Ultrafiltration membrane filter is a consumable. But ultrafiltration membrane filter is not to use the longer, the better, because of the effluent water quality change is no way to observed with the naked eye, life will be with the raw water quality and water pressure has a lot to do. When water water decreased obviously, which indicates that filter is serious, didn't have enough time, also need to replace filter.

second, you need to know in the market now commonly used three kind of ultrafiltration membrane water purifier: multilevel filter water purifier, central water purifier, stainless steel water purifier. Multilevel filter water purifier CSL membrane filter commonly used is the external pressure type filter, has quick type filter, easy plug type filter, lock teeth type filter and so on. And use the water purifier which need to use a filter, sample of the product appearance and size are compared, then confirm your need filter.

in the end, the need to seriously understand the quality of the filter element, must from the material of products, shell, appearance and so on various aspects to observe.

1, filter membrane silk material, general household PAN set of pp and PVC PVC alloy is better, the hydrophilic material, not easy jam, and the material itself has no harm to human body.

2, filter shell material, water purifier filter filter water to drink or use of water and water quality requirements for water is high. So the filter shell material requirement is high also, USES the food grade material, such as food grade ABS, UPVC material, etc.

3, membrane quality of silk, silk membrane pore size is even, the wall thickness is uniform and have eccentric, such as hollow fiber ultrafiltration membrane diameter: 0. 5 - 2. 0 mm, inside diameter: 0. 3 - 1. 4mm。

4, membrane filtration precision and filtration precision will directly determine the water quality, household water purifier ultrafiltration membrane filter filtration precision to 10 nm.

5, end face, whether fill full membrane silk, the location is distributed evenly centered. Membrane silk is full, can ensure that the amount of water in water; Membrane uniform distribution center, let the stress of the membrane filaments evenly, not easily lead to membrane rupture, ensure the service life of filter element.

6, whether face many membrane plug holes, plug hole too much will affect the water yield, side wall hole too much blind hole formation, affecting the water yield or smooth effect.

according to the specific circumstances, choose suitable ultrafiltration membrane filter, the filtering out of the water more clear, and the precision is high.
