The Structure and Operational Parameters of Pure Water Treatment Equipment

Pure water equipment 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.

Pure water equipment is a kind of water treatment and filtration equipment.

Purified Water Equipment: How Do They Function?

Pure water equipment 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.

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.
