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.
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.
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. microns, while the diameter of viruses is generally 0.02-0.4 microns, and the diameter of common bacteria is 0.4-1 microns.
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.
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.
*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.
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 $-$20,000.
1）Large water permeability and high salt rejection rate, which can reach ≥98%. Using imported composite reverse osmosis membranes, the produced water quality is excellent.

The water that comes out of your household tap travels through miles of pipes, aquifers, and treatment systems before landing in your glass. One of the easiest ways to boost the quality of that water is by using a water filter, be it under your sink, in your fridge, or on your countertop.
While many people buy water filters simply to improve the taste or appearance of their tap water, filtering your drinking water can also potentially protect you from harmful contaminants. A joint Consumer Reports-Guardian US news organization investigation of the nation’s tap water revealed that 118 of 120 tested locations across the U.S. had detectable amounts of lead, arsenic, or PFAS (per- and polyfluoroalkyl substances linked to significant health problems) above CR’s recommended maximum levels. Those sampled water systems served more than 19 million people.
An in-home water filter can not only protect against harmful contaminants but also improve the taste of your tap water. Because drinking-water complaints often relate to taste and smell, we test flavor and odor reduction in our current ratings for water filter pitchers, under-sink water filters, faucet-mounted filters, and countertop filters. Our ratings also include reverse osmosis water filters from previous testing.
In addition to refrigerator water filters, the most popular are pitcher-style filters—the kind you fill from the tap and keep in your fridge. They’re easy to use, require no installation, and take up less space than a more permanent option. They’re also relatively economical, with most costing less than $50.
Faucet-mounted water filters attach directly to your tap, while countertop water filters attach to your tap by a hose that diverts water through a small sink-side purifying device equipped with a spout. Both typically filter using granulated activated carbon cartridges that draw away contaminants before water leaves your tap. They work well for apartment dwellers because they don’t require a plumber to install. Faucet-mounted filters often cost less than $50. Countertop filters can cost $80 or much more, depending on the filtration system they use.
