DI Water System price Deionized Water Definition Deionized water means water that is partly or totally free from minerals, such as Na, Ca, Mg, Cl and SO4 etc., so it is also called demineralized water or DM water.聽 For many applications, water are used as a rinse or ingredient, so the ions are regarded as impurities and must be removed from water. Partial deionized water can be produced on-site for immediate use or purchased in container. But total deionized water can only be produced on-site for immediate use, because total deionized water can be polluted by air or the container, so it cannot be transported or stored. Reverse Osmosis Deionized Water System is to produce deionzied water by reverse osmosis. How to Make Deionized Water Deionization is a process of removing ions or minerals, which several technologies can be used. For example: Two Bed Ion Exchange System聽 It is a vessel filled with cation exchange resin and anion exchange resin. Water flows through the mixed bed, cation will be exchanged by H+ and anion changed by OH-, then water is purified.聽 And with running time accumulate, the ion exchange resins deplete, then the resins need to be regenerated by HCl and NaOH. So there will be the following points need to be noticed: 1. The regeneration period is long, so you will need to install a standby system if your water requirement is continuously.聽 2. Two people needed at least. 3. The effective period will become shorter and shorter as the service time goes by. Then regeneration frequency will increase. 4. Regeneration process is a little bit dangerous although workers are with protection articles. 5. The effective exchanging period is determined by several factors, such as the operator鈥檚 skill level and proficiency, the quality of regenerant, pretreated water quality, ion exchange resin quality and so on, so the system may stop for some human factors. Reverse Osmosis Deionized Water System Reverse osmosis is a membrane filtering technology, to separate water and impurities expecially ions. RO membrane only let water molecules pass while reject others. As water flow through, then there will be a osmotic pressure to prevent water pass continuously. To solve this problem, outside pressure need to be involved. As the high pressure side is with nearly total impurities, so we call it concentrate side, and the pure water side is called permeate side. And conc. can be discharged directly. This way, deionized water is produced. And remembrane system don't need acid-alkali regeneration.
