Commercial Water Dispenser is a water treatment equipment that can filter and purify water according to water demand. The water purifier we usually talk about is actually one of the water purifiers with the most precise filtration and the highest degree of filtration, also known as the "terminal water purifier".
Therefore, in fact, many consumers are confused about buying ordinary water purifiers from water dispenser suppliers or pure water purifiers. What is the difference between them?
Then, let us analyze its working principle, application scope, advantages, and shortcomings to clarify the relationship between them and find the most suitable water purifier.
Comparison of working principle
Water purifier: a progressive structure model adopting the principle of stepwise shielding and filtering. It is composed of multi-stage filter elements connected in series from beginning to end. The accuracy of the filter elements is arranged in order from low to high to achieve multi-stage filter element sharing and retention of dirt, thereby reducing filter element clogging and manual drainage, the number of disassembly and cleaning, and extending the service life of the filter element. The cycle of replacing the filter element.
Pure water machine: mainly adopts reverse osmosis membrane technology. The working principle of the water purifier is to apply a certain pressure to the water so that water molecules and ionic mineral elements can pass through the reverse osmosis membrane, and most inorganic salts (including heavy metals), organic matter, bacteria, viruses, etc. are dissolved in the water Can not pass through the reverse osmosis membrane, so that the permeated purified water and permeated concentrated water can be strictly separated.
Applicable places and personnel
1. Applicable places
Water purifier: kitchen water; bathroom water; heated drinking water
Pure water machine: direct drinking; clean water for kitchen and bathroom
2. Applicable crowd
Water purifier: families with higher requirements for cooking and washing; families pursuing economic and health
Purified water machine: There are babies, pregnant women, and the elderly at home; pursuing the taste and quality of drinking water
Comparison of advantages
Water purifier: precise filtration; economical and convenient mineral retention
Pure water machine: 99% filtration; improved taste; known as "the safest water in the world"
The purified water processed by the water purifier meets the national standards for original drinking water and can be used as direct drinking water. Tap water is filtered by a pure water machine to obtain purified water, which is the same as the purified water we buy in the supermarket.
Shortcoming comparison
Water purifier: \u2460The taste is slightly poor. \u2461Unable to remove heavy metals, viruses, and other chemical pollutants (three ultrafiltration). \u2462It is impossible to remove scale and fluoride mainly composed of calcium and magnesium ions (three-stage and three-stage filtration).
Pure water machine: \u2460 Some of them need electricity. \u2461Some wastewater will be produced. (Wastewater here refers to filtered water that cannot be directly drunk. It can be used for watering flowers, washing faces, mopping floors, and other activities.)
