How to Choose Pure Water System?-NEWater

Pure water system is a kind of water treatment and filtration equipment. After filtering raw water (physical method), it does not add any compounds to produce equipment that meets the quality standard of drinking water.

So what is the best pure water machine? In this article, NEWater introduces you to the advantages of high-quality pure water equipment.

1. What is Pure Water? Why is It Important?

What is pure water? We need to understand the meaning of “pure water” and “purified water”.

Pure water: also known as high-purity water, refers to water with extremely high chemical purity. It is a kind of water without impurities, ions, and molecules, that is, only H20 molecules.
If pure water is used as drinking water, it may destroy the physiological balance of the human body and cause harm to health. However, pure water is suitable for applications that require very high water purity, such as biology, chemistry, metallurgy, electronics industry, preparation of laboratory reagents, equipment cleaning, and other specific occasions.

Purified water: Purified water is water that has been processed through multiple processes and is suitable for drinking and other purposes. During the water filtration process, impurities and harmful substances in the water, such as organic matter, inorganic matter, bacteria, and other pollutants, are removed to ensure the purity and health safety of the water.
Common treatment technologies include filtration, reverse osmosis, ultraviolet sterilization, and other methods. Therefore, purified water is usually more suitable for people’s drinking and use needs than pure water.

2. Pure Water System: How Do They Function?

Water filtration system mainly adopts reverse osmosis membrane technology. Its working principle is to apply a certain pressure to the water, so that water molecules and ionic mineral elements pass through the reverse osmosis membrane, while most of the organic matter, heavy metals, bacteria, viruses, etc. dissolved in the water cannot pass through the reverse osmosis membrane.

Thereby separating the permeated pure water and the impermeable concentrated water. The pore size of the reverse osmosis membrane is only 0.0001 microns, while the diameter of viruses is generally 0.02-0.4 microns, and the diameter of common bacteria is 0.4-1 microns.

3. Pure Water Equipment Components

The pure water system generally refers to a device that achieves purified water through various water treatment processes and water quality monitoring systems. Common impurities in natural water include organic matter, particulate matter, soluble inorganic matter, microorganisms, etc. Generally, the water purification process can be roughly divided into pretreatment and reverse osmosis.

Pretreatment: The pretreated water will be further purified through reverse osmosis, so impurities that affect the reverse osmosis membrane must be removed. These impurities primarily mainly include large particles, residual chlorine, and calcium and magnesium ions. The quartz sand filter, activated carbon filter, and water softener are designed to remove large particles, residual chlorine, and calcium and magnesium ions from the water to obtain the optimum pretreatment effect.

Reverse osmosis: In reverse osmosis, a high-pressure pump is utilized to produce a high-concentration solution with a pressure greater than the osmotic pressure difference. On the low-concentration side, water molecules will be forced to pass through a semi-permeable membrane. Reverse osmosis can remove particles, colloids, and organic contaminants from water, as well as 99% of dissolved salts, heavy metal ions, bacteria, viruses, and other toxic compounds, and heavy metal ions.

Pure Water Equipment Components

Ion exchange: Ion exchange means the exchange of positive ions in the water with the H+ ions in the ion exchange resin, and the exchange of the negative ions in the water with the OH- ions in the ion exchange resin, thereby achieving the purpose of purifying water. Removing ions through ion exchange can theoretically remove almost all ionic substances. At 25°C, the effluent resistivity reaches 18.2MΩ. cm. The quality of the ion-exchange water mainly depends on the quality of the ion-exchange resin and the exchange efficiency between water and resin in the exchange column.

Terminal handling: Mainly according to the special requirements of customers, we produce ultra-low organic type, sterile type, non-pyrogenic type, etc. ultrapure water. There are a variety of treatment methods for different requirements, such as ultrafiltration to remove heat sources, dual-wavelength ultraviolet oxidation to reduce total organic carbon (TOC) in water, microfiltration to remove bacteria, etc.

4. How to Choose the Best Pure Water Machine?

-Factors to consider before buying a water purifier:

*Raw water quality and water production quality

In general, the quality of incoming water and the requirements of produced water will determine the engineer’s design program to take into account more processes. The poorer the quality of the incoming water and the higher the water quality requirements of the produced water, then the cost of the equipment and processing of consumables, raw materials, and other operating costs will be more expensive.

*Water production
Usually, the amount of water production is directly affect the price of the pure water system. Therefore, it is important to choose the most appropriate size of the flow.

* With and without pumps
We prefer to choose a pump. Because the process of using it will be more convenient, and it can be guaranteed to be used when the water pressure is low. A water purifier with a pump has a better purification effect than a water purifier without a pump.

*Manual flushing or automatic flushing
The water purifier flushing function is to clean the RO membrane for a long time after the use of the surface of the scale, microorganisms, etc., to achieve the RO membrane surface cleaning and protection. The automatic water purification system will be more expensive than the manual one.

-NEWater provides you with the following characteristics of a pure water system to facilitate your choice:

  • The host adopts an integrated design, has a small footprint, and can be installed flexibly.
  • High filtration precision and large flow rate.
  • The system is set to boot self-test, automatic flushing, automatic liquid level protection, and automatic high and low voltage fault protection functions.
  • With quality inspection certificate, and quality assurance.
  • Using high-end accessories, the service life of the equipment is longer.

5. How Much is Pure Water Machine?

There are many varieties of water purification equipment, including reverse osmosis (RO) water purification equipment, ultrafiltration water purification equipment, ion exchange equipment, water softening equipment, direct drinking water equipment, ultrapure water machines, activated carbon filters, and so on.

According to the use of split and integrated equipment. The split system has a larger footprint, with the water storage drum and the body separated; the mainframe and the water storage drum of the integrated water purifier are together, with a small footprint.

The price of pure water equipment will be determined according to the required configuration, water output, and water quality requirements. In addition, for different manufacturers, the price of the equipment will also vary. The cost usually ranges from $1300-$20,000.
