What kinds of household water purifiers are there?
Dec 17, 2018

The safety of drinking water has received more and more attention from everyone. Household water purifiers have gradually become familiar and accepted, and the current penetration rate is also very high. At present, there are many types of household water purifiers. Different types of water purifiers have different use characteristics. Now domestic water purifier manufacturers introduce five kinds of water purifier products that are very hot at present:

1. PP cotton filter water purifier: It is a single-cylinder water purifier equipped with various PP cotton filter cores. The general price of this machine is low, but the filter element is easy to block, the replacement frequency is high, and the precision of filtration is not very high. This is only used for initial filtration of water and cannot be consumed directly.

2, RO reverse osmosis pure water machine: pure water machine can completely remove harmful substances in the water, the purified water is pure water. The pressure of the water is not enough for its working pressure, so a booster pump is needed, which requires electricity and pressure. Its biggest drawback is that there is more wastewater, and it is generally necessary to filter out about 50% of wastewater. It has higher purification costs and less water production and can only be used to solve drinking water problems.

3, activated carbon filter: activated carbon super strong adsorption can remove the color and odor in the water, but can not eliminate bacteria and other harmful substances in the water, pure activated carbon water purifier and sediment, rust removal effect is also Poor.

4, soft water machine: The biggest effect of the water softener is to be able to soften the water, reduce the hardness of the water, and then reduce the scale. The general softening method is to replace the calcium and magnesium ions in the water with a regenerated sodium resin. However, it does not purify or remove various harmful pollutants in the water.

5, ultrafiltration machine: ultrafiltration water purifier can effectively remove sediment, suspended solids, rust, bacteria, colloids and some macromolecular organic matter, etc., can effectively retain some of the minerals, trace elements and other beneficial to us. Its advantages are long filter life, large water output, no need to apply electric pressure, and low cost compared with other purification equipment, which is very suitable for domestic water purification.
