How to choose the suitable water treatment filter - 【 3 m filter.

Filtering mechanism? 吗?

fluid from the filter element inside to outside, the bag to filter out particles trapped inside the bag, the bag filtering works by pressure filtration. A complete set of bag filter system includes three parts: filter vessel, support a basket with netting on top and the filter element. 吗? 吗?

to filter the liquid from the top is supported on top of water treatment filter injection, which makes the liquid is uniformly distributed in the surface of filter, so the medium flow distribution is consistent with the surface, without the negative effects of turbulence.

fluid from the filter element inside to outside, the bag to filter out particles trapped inside the bag, when the filter element changed from pollution has filtered liquid. Within the filter core design makes the handle of the filter element replacement quick and easy.

characteristics are as follows:? 吗? 吗?

high flow capacity; 吗? 吗?

a long service life of filter element; 吗? 吗?

the uniform flow of liquid evenly distribution of pellet impurity on the filter bed inside the filter.

high filtering efficiency, the cost is low.

　　1. The selection of the filter material? 吗?

first according to the chemical name to filter the fluid, according to the chemical with taboo to find available filter material, again according to its operating temperature, operating pressure, ph, operating conditions ( Such as, whether to need to tolerate steam, hot water or chemical sterilization, etc. ) Does not apply, assessed, and eliminate the filter material. Purpose is also an important consideration, for example of drug, food or cosmetics use filter material must be the material of the FDA granted; Ultrapure water must choose pure, does not contain release content will affect than the impedance of the filter material; Filtering gas must choose hydrophobic material and whether need & quot; Health grade filter & quot; Design and so on.

　　2. Filtration precision?

this is a confusing problem. For example, to get rid of visible particles, should choose 25 micron filter cartridge; To remove fluid in the cloud, and to choose 1 or 5 micron filter core; To filter out small bacteria is 0. 2 micron filter element. The problem is that there are two kinds of filtration precision unit: absolute accuracy/nominal accuracy.
