How often should the filter elements of different materials of the ultrapure water machine be replaced?

       The ultra-pure water machine is used to filter suspended solids in the water, and remove heavy metals, germs, virus infections, etc. It has high filtering technology. The first stage is PP cotton filter element, and the second and third stages are activated carbon. +Activated carbon or activated carbon + PP cotton, the fourth stage is ROro reverse osmosis membrane, and the fifth stage is a high-precision filter element. The replacement cycle of the filter element of different materials of the ultrapure water machine is different. Let's talk about it in detail.

1.PE filter element:

The diameter of the filter varies in size, generally around 0.1 microns. Efficacy: Isolate red nematodes, stone materials, rust, colloidal solution and other residues that can be seen by human eyes in the water, and the use period is 1~2 months.

2. PP melt spray filter element:

The diameter of the filter varies in size, generally around 5 microns. Efficacy: Isolate residues exceeding 5 microns in water and colloidal solution, rust and microbial strains in water, and the use period is 3 to 6 months.

3. Ceramic filter element:

The filter diameter is 0.1 micron, which is slightly larger than the raw material of ultrafiltration membrane. Efficacy: filter out germs, pyrogens, microbial strains and colloidal solution in the water, significantly reduce the turbidity in the water, the use period is 12~24 months.

4. Ultrafiltration material filter element:

The diameter is 0.01μm. Efficacy: filter out germs, pyrogens, microbial strains, and biological macromolecular organic compounds in the water, and the use period is generally 12 to 24 months.

5. Activated carbon filter element:

Efficacy: Absorbs (chlorine), different colors and odors in water. The filter element is also subdivided into different types, and the service life varies from 6 to 18 months.

6. RO reverse osmosis membrane:

The diameter reaches 10-6μm. Efficacy: filter out small molecular water organic compounds, germs, virus infections, minerals, etc. in the water. The service period is related to the pre-treatment filter element (PP filter element, filter element) and the ratio of waste water, generally 18 to 36 months.
