The current water purifier market is full of competition, and the types of water purifiers are also dazzling.There are front water purifiers, faucet water purifiers, kitchen water purifiers, sprinkler water purifiers, water softeners, etc.At present, membrane separation technology is commonly used to filter and purify water. Membrane separation technology is usually divided into four categories: microfiltration, ultrafiltration, sodium filtration, and reverse osmosis.
Today I will show you what types of water purifiers are available, and what are the filtering effects of various water purifiers?

1.Microfiltration(MF)
The filtration accuracy is generally 0.1-50 microns,common PP filter elements, activated carbon filter elements, ceramic filter elements, etc. belong to the category of microfiltration.Used for simple coarse filtration to filter large particles of impurities such as sand, rust, etc. in the water,but it cannot remove harmful substances such as bacteria in the water. The filter element usually cannot be cleaned. It is a disposable filter material and needs to be replaced frequently.

2.Ultrafiltration(UF)
The filtration accuracy is 0.001-0.1 microns, which is one of the high and new technologies in the 21st century.It is a membrane separation technology that uses differential pressure to filter out harmful substances such as rust, sand, suspended solids, colloids, bacteria, and macromolecular organics in the water, and can retain some mineral elements that are beneficial to the human body.It is the core component in the production process of mineral water and mountain spring water.It is not easy to be blocked and has a relatively long service life.

3.Nanofiltration(NF)
The filtration accuracy is between ultrafiltration and reverse osmosis, and the salt rejection rate is lower than that of reverse osmosis,it is also a membrane separation technology that requires power and pressure, and the water recovery rate is low. Generally used in the manufacture of industrial pure water.
4.Reverse osmosis(RO)
The filtration accuracy is about 0.0001 micron. It is an ultra-high-precision membrane separation technology using differential pressure developed in the early 1960s in the United States.It can filter out almost all impurities (including harmful and beneficial) in the water, and can only allow water molecules to pass through. It is generally used for the production of purified water, industrial ultrapure water, and medical ultrapure water.The reverse osmosis machine is also referred to as the pure water machine, commonly known as the RO machine. General products have 5-stage filter elements, and some high-end water purifiers contain 7-stage filter elements.

So the best water purifier depends on personal needs.Just choose according to your needs.

In the face of today's water quality problems are becoming more and more serious, a high-performance water purifier has become a modern family almost a must-have thing. But in the variety of the market, how to buy a water purifier that really suits you? The purpose of this article is to reveal for you to buy a water purifier of the whole picture, to help you pick the desired product, so that your water back to pure.
Second, the face of water purification:
Understanding the types of water purifiersThere are many types of water purifiers, each of which has its own unique application scenarios and characteristics.1. Ultra-filtration water purifiers: suitable for relatively good water quality in the region, the main filtration of impurities and odors.2. Reverse osmosis water purifiers: known as water purification sector “all-rounders” to remove heavy metals, bacteria, viruses, etc., to provide more pure drinking water.3. Nanofiltration water purifiers: called water purification sector “all-rounders” to remove heavy metals, bacteria, viruses, etc., to provide a more pure drinking water. Nanofiltration water purifier: between ultrafiltration and reverse osmosis, able to filter out most of the harmful substances. 4. activated carbon water purifier: mainly relying on activated carbon adsorption of odor, pigmentation, etc..

How much do you know about ultrafiltration technology and ultrafiltration membranes? Ultrafiltration membrane technology is an important technology for water treatment in environmental protection projects. It has extremely broad application prospects in urban sewage treatment, various industrial wastewater treatment, and recovery of useful substances. At present, one of the research directions of ultrafiltration membrane technology is to invent more efficient ultrafiltration devices, and the other is to combine it with other water treatment technologies based on the characteristics of the incoming water quality to improve the quality of the effluent.
