Popularization of Domestic Water Filter Knowledge Part1

Published by admin December 04,2019

Why install water filter?

Bacteria, viruses, parasites, etc. in the water of our domestic tap water can only be killed after boiling, boiling can not effectively remove rust, heavy metals, antibiotics, etc. in the water, long-term drinking will have a very adverse impact on our health. The use of RO water filter can effectively remove all kinds of pollutants contained in the water.

Why does the water filter cartridge need to be replaced regularly?

Regular renewal of the water filter cartridge can ensure water quality; if it is not replaced for a long time, the filter membrane in the water filter cartridge will be easily blocked, which will reduce the service life of the water filter cartridge, and more importantly, it will affect the filtering effect (reduction of water yield); if the water filter cartridge is not replaced for a long time, impurities and bacteria will remain on the outer, which is easy to cause secondary pollution.

What is the waste water ratio?

Waste water ratio refers to the volume ratio of pure water produced by water filter and discharged waste water in unit time. For example, the "ratio of 1:1" of water filter means that when the water filter is making water, each unit of pure water will produce a unit of waste water.

It is worth noticing that the waste water output of RO water filter is very high. In order to ensure the long life of RO membrane, increasing the waste water ratio can prevent the fouling damage of RO membrane. Generally speaking, the waste water rate of RO water filter has developed from the earliest 5:1 to 3:1 or even 2:1, that is to say, one cup of pure water generated will waste two cups of water with the same volume. Of course, even the water called "waste water" is very clean. Its purity is higher than the raw water, but its salinity is higher. It will not be wasted to wash clothes, mop the floor or flush the toilet.
