All kinds of filter replacement in reverse osmosis treatment technology is introduced 【 3 m filter.

In the process of the reverse osmosis device is one of the core device, its stable operation is related to the chemical water treatment process, the stable operation of the boiler system, and the follow-up process. Filter is the key to ensure the safe and stable operation of reverse osmosis device consumes the material, the filter replacement time should be 1 to 3 months, if change time is less than 1 month, system existence question, the service life and stable operation of reverse osmosis membrane potential hazards.

　　1. PE filter: filter aperture is small, generally at 0. About 1 micron.

: cut off the water to the naked eye can see red worms, impurities such as sand, rust, colloid, service life is 1 ~ 2 months.

　　2. PP solution spray filter material: filter aperture have greatly small, generally in 5 microns.

: greater than 5 microns impurities and water cut off the water colloid, rust and microbes, service life is 3 ~ 6 months.

　　3. Ceramic filter: filter aperture at 0. Is a little bigger than 1 micron, ultrafiltration material.

: filter the bacteria in the water, heat, microbial and colloid, significantly reduce the turbidity of the water, life for 12 ~ 24 months.

　　4. Ultrafiltration filter material: aperture at 0. 01 microns.

: filter the bacteria in the water, heat, macromolecular organic matter, microorganism, the service life of the general for 12 ~ 24 months.

　　5. Activated carbon filter:

: the water absorption of bleaching powder ( Chloride) , different color and odor. Activated carbon filter is subdivided into different types, service life is 6 ~ 18 months.

　　6. RO reverse osmosis membrane pore size can be up to 10 - 6 microns.

: filter out the small molecule organic matter in the water, bacteria, viruses, minerals, etc. Service life and pretreatment of filter ( PP filter, activated carbon filter) And wastewater than other related, general is 18 ~ 36 months.

also known from the effect of reverse osmosis unit RO reverse osmosis membrane is in U. S. space technology, invest a lot of manpower and financial resources, after many years of research and development, and the filter element as a result of the reverse osmosis membrane aperture cases far less poison and bacteria hundreds or even thousands of times more, so a variety of viruses, bacteria, heavy metals, soluble solid content, organic matter pollution, such as calcium and magnesium ions could not through the reverse osmosis membrane, thus achieve the goal of softening water quality purification.
