The difference between pure water and purified water in reverse osmosis machines

Pure water: refers to water that has undergone RO membrane filtration and is free of residues such as excessive heavy metals, dirt, bacteria, virus infections, and air pollutants.

Pure water, which can be consumed immediately and directly, is generally used as household water.

Purified water: In the sales market, purified water refers to non RO (RO reverse osmosis) water, most of which refers to ultrafiltration membrane water. Generally, water that has been cleaned by PP cotton, activated carbon, and some initial and intermediate filters is called purified water.

Purified water is not suggested to be drunk directly. It is generally used as the tap water in the kitchen of the restaurant and is used to wash dishes, cook rice, boil soup, and cook Congee.

The surface of the membrane is covered with many fine microporous plates, which only allow water and small molecule water chemicals to become passing liquids. However, chemicals in the source liquid with a volume exceeding the micro diameter of the membrane surface are intercepted on the leakage side of the membrane, becoming the extraction liquid, thus achieving the goal of cleaning, separating, and concentrating the source liquid. The wall thickness of each meter long Dow reverse osmosis membrane filament is approximately 6 billion times 0.01 μ The diameter of the microporous plate of m only allows for water, favorable minerals and nutrients in the water, while the volume of less pathogenic bacteria is 0.02 μ Above m, bacteria and their much larger colloidal solutions, rust, suspended solids, fine sand, and biomolecular organic compounds can all be intercepted by the Dow reverse osmosis membrane, thus completing the entire cleaning process.

Pure water machine RO reverse osmosis, also known as RO reverse osmosis, with a precision of 0.1 nanometers, is a membrane separation technology that uses pressure difference as the driving force to separate organic solvents from aqueous solutions. When pressure is applied to the liquid on one side of the membrane, when the working pressure exceeds its permeation concentration, the organic solvent will penetrate in the opposite direction from the direction of natural infiltration. Then, the organic solvent passing through the bottom pressure side of the membrane, namely the permeate, is obtained; The high-pressure side obtains a concentrated aqueous solution, which is the extraction solution. RO reverse osmosis membrane can not only intercept the residue that can be intercepted by Dow reverse osmosis membrane, but also intercept the concentration of various inorganic ions, colloidal solution chemicals, and biological macromolecules in the flowing water. Only water and small amounts of nutrients can pass through to obtain purified water.
