Know the life cycle of consumables for reverse osmosis deionized water equipment? Author: pure water reverse osmosis deionized water equipment processing effects are evident to all, which is why more and more enterprises begin to use reason reverse osmosis deionized water equipment. The reverse osmosis deionized pure water equipment is to pass the raw water through a quartz sand filter, an activated carbon filter, a scale inhibitor, a precision filter, etc., and then pressurize it by a pump, using a reverse osmosis membrane (RO membrane) with a pore size of 1/10000μm , The process of turning higher-concentration water into low-concentration water. In order to make the reverse osmosis deionized water equipment long life, it is necessary to regularly maintain it and replace consumables. The consumables of reverse osmosis deionized water equipment mainly include quartz sand, activated carbon, softening resin, PP filter element, and reverse osmosis membrane. Let's introduce the replacement cycle of consumables! 1. Quartz sand quartz sand filter material plays a filtering role in reverse osmosis pure water equipment, just like water penetrates into the ground through sand and gravel, it is used to intercept particulate impurities such as suspended solids in water, mainly for those fine suspended solids. So as to play a filtering role. The normal service life is about 8-24 months. Quartz sand is made of quartz sand, the color is pure white, and the quartz sand filter material is produced and processed in strict accordance with the filter material standard for water treatment. 2. The normal service life of activated carbon is about 8-24 months, and its main function is to remove macromolecular organic matter, iron oxides and residual chlorine. The ability of activated carbon to retain suspended solids comes from the surface area provided by activated carbon. When the flow rate is low, the filtration capacity of the reverse osmosis pure water equipment unit mainly comes from the screening effect of activated carbon, and when the flow rate is fast, the filtration capacity comes from the adsorption of the surface of the activated carbon particles. The larger the surface area of u200bu200bthe particles provided by the activated carbon during the filtration process , The stronger the adhesion to suspended solids in water. 3. Softening resin The normal service life of softening resin is about 8-24 months. Cation exchange resin is a polymer with corresponding functional groups. In general, conventional sodium ion exchange resins contain a large amount of sodium ions. When the content of calcium and magnesium ions in the water is high, the ion exchange resin can release sodium ions, and the functional groups combine with calcium and magnesium ions, so that the content of calcium and magnesium ions in the water decreases, the hardness of the water decreases, and hard water becomes soft water. 4. The replacement cycle of PP cotton filter element: the normal service life is about 10-30 days. A precision filter is used to remove residual suspended solids, non-curved particles and colloids in the influent, so that the RO system and other subsequent equipment are safer. And stability. 5. RO membrane replacement cycle: the normal service life is about 3-5 years. Reverse osmosis RO membranes are generally made of polymer materials. The diameter of the surface micropores is generally between 0.5 and 10 nm, and the permeability is related to the chemical structure of the membrane itself. The reverse osmosis membrane has a small membrane pore size, so it can remove dissolved salts, colloids, organic matter, etc. in the water. The chemical structure of some polymer materials has more hydrophilic groups, so the water penetration rate is relatively fast.
