1, ro water tank water is pure water. ro water tank that is reverse osmosis pure water equipment, through the reverse osmosis equipment application of membrane separation technology, can effectively remove the charged ions in the water, inorganic substances, colloidal particles, bacteria and organic substances, etc., is the preparation of high purity water, desalination of brackish water and wastewater treatment process in the best equipment. Therefore, ro pure water is generally called pure water, basically does not retain the minerals in the water, PH value between 6-7, weak acidity, generally used for dialysis and other medical water, or laboratories, electronic chemicals and other special water, due to serious water pollution, in order to protect the safety of drinking water, but also used for daily drinking water, is hygienic, safe drinking water.
2, RO water, reverse osmosis water, is also commercially available pure water. The principle is to apply greater than the osmotic pressure at one end of the original water, and reverse osmosis effect, at this time dissolved and non-dissolved inorganic salts, heavy metals, organic bacteria particles can not pass through the semi-permeable membrane, so that the water molecules and smaller molecules of salts seepage through the semi-permeable membrane, flow to the side of the water purification, and the pollution of the ingredients are concentrated in the original water. Raw water is gradually concentrated, the pressure applied must be gradually increased until infinity. The actual operation is to concentrate the water (wastewater) discharge, continue to supply into the raw water, in order to maintain a constant pressure. Simply put the principle of reverse osmosis function, like a sieve, the water is forced through a film like cellophane, in which only very small organic particles (particles) can pass, and contaminated unclean water is discharged by the wastewater outlet. It can be drunk directly.
