Why should we use water purifiers?Water Purifier Provider
It is because the water quality in many places is really worrying, that first, we have to learn to judge the water quality.
First of all, there are two main reasons for poor water quality, one is some northern areas or more serious pollution areas, will focus on the problem of poor water quality, this is not water pollution, but that the smell of chlorine is relatively heavy, the home scale is heavy. Another is the water quality problems brought about by old and corroded water pipes, some of the older cities will encounter this aspect of urban construction.
Then, how to determine whether the water quality is poor?
On the one hand, you can use the senses to determine the color of the water yellow, black or white, the water has a strange object suspended in the water, after boiling a large amount of scale, or a relatively heavy chlorine smell. On the other hand, you can use the water quality monitoring pen to determine, this can be the most intuitive way to determine the water quality problems, this is also my common way now.
How does a water purifier filter the “dirty” stuff in the water?
The common water purifier on the market mainly consists of pp cotton, activated carbon, and filtration membrane materials, belonging to the composite water purifier.
(1) PP cotton to block the water rust, sediment and other particulate impurities;
(2) activated carbon material can decolorize and deodorize the water, and can remove chemicals that may be harmful to humans, such as residual chlorine and organic matter;
Membrane materials are mainly divided into four types of microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) according to the size of the membrane pore size.
And we often buy the water purifier is divided into ultrafiltration water purifier and reverse osmosis water purifier two.
So, these composite water purifiers can optimize drinking water quality, including reducing color/turbidity, removing organic matter, residual chlorine and retaining microorganisms, etc. RO reverse osmosis water purifiers have a filtration accuracy of 0.0001 microns, allowing only water molecules to pass through, and the filtered water can be consumed directly, so it is the safest from the water quality point of view.
