What is Deionized Water,Ultra-pure Water,High-purity Water
Deionized Water: It refers to pure water that has had impurities in ionic form removed. International Organization for StandardizationISO/TC 147The defined "deionization" refers to: "Deionized water completely or partially removes ionic substances, primarily through the method of ion exchange resin treatment." The current process mainly employs...ROThe method of reverse osmosis for production. In the semiconductor industry, deionized water is referred to as "ultrapure water" or "high-purity water."
1Deionized Water: Water is passed through an anion-cation exchange resin bed, where the ions are exchanged, resulting in deionized water, which is commonly used for laboratory water needs in chemistry. Standards can be found in the Laboratory Water Standards.
2Distilled Water: Water obtained by condensing steam through distillation is known as distilled water. Typically, large-scale water production involves steam generated from boilers, which is then condensed to create the water.
3Pure Water: Purified through sand filtration, odor removal by activated carbon, and further filtered by reverse osmosis membranes to remove ions, this water is also known as pure water or space water (a water recycling technology in aerospace). The pure water available on the market is prepared in this manner. Standards are outlined in the "Pure Water Hygiene Standard" under food hygiene regulations.
Process for Producing Deionized Water
4、The method of producing deionized water by combining reverse osmosis water treatment equipment with ion exchange equipment follows a basic process flow: Original Water→Multi-media Filter → Activated Carbon Filter → Precision Filter → Reverse Osmosis System → Mixed Bed → Ultra-Pure Water Tank → Ultra-Pure Water Pump → Post-Filter → Drinking Point (Features: Low pollution, high level of automation, moderate initial investment, reasonable price)
5Reverse Osmosis Equipment and ElectrodeionizationEDIThe method of producing deionized water through equipment matching is a process for producing ultra-pure water, which is also an environmentally friendly, cost-effective, and highly promising ultra-pure water preparation process. Its basic process flow is:
Original Water→ Multimedium Filter → Activated Carbon Filter → Precision Filter → Reverse Osmosis Equipment → Electrodeionization (EDI)EDIUltra-Pure Water Tank → Ultra-Pure Water Pump → Post-Filter Security System → Water Usage Points (Features: environmentally friendly, high level of automation, high initial investment, relatively expensive price)
