Firstly, different water treatment equipment should be selected according to the different water quality. For example, the water quality in northern China is harder than that in southern limestone area. The calcium and magnesium ions in the water are higher and easy to scale. So soft water with resin filter core of ion exchange deionization water treatment equipment should be selected. Machine (Note: Softened water is not recommended to drink directly, because the sodium ions exchanged with calcium and magnesium ions in water will increase in a certain proportion. Only recommended for domestic water use.) In urban and rural tap water, KDF filter element plus activated carbon and ultrafiltration membrane can be used as water purifier because of the high content of chlorine and organic substances and the heavy odor. Water quality is special, such as serious pollution of water quality, water equipment requiring thorough glass tank membrane cleaning to filter out bacteria, viruses, odor, pesticides, metal ions and other pollutants in water. For its impurities, direct drinking water purifiers with reverse osmosis membranes should be selected.

Water treatment equipment can be divided into two categories: water purifier and water softener.

Water purifier:

According to the different filter diameter and technology, the water purifier can be divided into three parts: activated carbon adsorption (including granular activated carbon, fiber activated carbon, etc.), microfiltration, ultrafiltration, nanofiltration and RO reverse osmosis.

1. Activated carbon is a very small carbon particle with a large surface area, and there are even smaller pores in the carbon particle - capillary. This kind of capillary has a strong adsorption capacity. Because of the large surface area of carbon particles, it can fully contact with gas (impurities). When these gases (impurities) meet the capillary, they will be adsorbed and play a net role. Chemical reaction. Its advantage is that it has a large amount of water.

2. Because of its large filter diameter and low cost, the micro-filter water purifier can not get a good effect on the quality of the effluent. If combined with manufacturers'efforts to render and low prices, it will confuse a large part of consumers who do not understand water treatment equipment.

3. Ultrafiltration-grade water purifier will greatly improve the water quality. The filter diameter of 0.1-0.01 micron can remove all bacteria and most viruses. Ultrafiltration water purifier is also the main force in the market because of its perfect technology.

The cost is moderate, and the function can also meet the needs of ordinary families.

Applicable crowd: For general consumers, the water quality requirements for domestic water are not very high, only hope that the water quality is clean, no odor, good taste on the line.

4. RO reverse osmosis membrane-level nanofiltration has a higher diameter of 0.01-0.001 micron.

Suitable crowd: Suitable for busy working people, people who pursue the quality of life, especially families with old people and children.

Although the process of water softener is only resin ion exchange technology is quite mature. But the exchange capacity and speed of resin are all the quality indexes of resin. Consumers should have a preliminary understanding before buying.

Suitable crowd: When bathing, we often see scales on glass bathroom or glass door, and macula on laundry and equipment. This is the trouble caused by "hard water". The water softener is suitable for people with high water requirement and sensitive skin, such as the elderly, children and women. Another advantage of soft water is that it can make the water-related equipment scale-free, give full play to its efficiency, and save energy.
