Ion exchange method for water purification of ultra pure water equipment

Ion exchange method of water quality purification method of ultra pure water equipment Author: Chengdu Tangshi Corning Technology Development Co., Ltd the ion exchange method of ultra pure water equipment is to filter the raw water with a round spherical resin (ion exchange resin) The ions in the water will exchange with the ions fixed on the resin Hard water softening and deionization are two common methods The hard water softening of ultra pure water equipment is a pretreatment procedure to reduce the hardness of water quality before RO treatment in ultra pure water machine The spherical resin in the softener exchanges two sodium ions for one calcium ion or magnesium ion to soften the water quality The ion exchange resin of ultrapure water equipment uses hydrogen ion to exchange cations, while the anion is exchanged with hydrogen ion; the cation exchange resin made of styrene and divinylbenzene containing sulfonate will exchange various cations (such as Na +, Ca2 +, Al3 +) encountered with hydrogen ion Similarly, the working principle of the ultrapure water machine is that the anion exchange resin made of styrene containing quaternary ammonium salt will exchange various anions (such as Cl -) encountered by hydrogen peroxide ion The hydrogen ion released from the cation exchange resin is combined with the hydrogen ion released from the anion exchange resin to form pure water If the ion exchange method is combined with other ultra pure water purification methods (such as reverse osmosis, filtration and activated carbon adsorption), the ion exchange method will play a very important part in the whole purification system Ion exchange can effectively remove ions, but can not effectively remove most of the organic matter or microorganisms The microorganism can attach to the resin and take the resin as the culture medium, so that the microorganism can grow rapidly and generate heat source Therefore, it needs to be used in combination with other purification methods
