Катион и анион обмен устройство

Cation&Anion exchange device Mixed bed is a deeper desalination equipment,which is used to make hyperpure water,and the contributing water resistivity is 10-18MΩ.CM ,and the content of silicon dioxide (SIO2),<0.02mg/L.Mixed bed is divided into single bed and double bed and polishing bed ;double bed includes in-use one and spare one,which can be in parallel connection and series connection .In mixed bed ,cation and anion are evenly mixed,ion exchang reaction is almost conducted simultaneously,which is equal to multiple level double bed series connection.However,there is a strict requirement to the quality of feeding water in mixed bed .And reverse osmosis or double bed shall be used as pretreatment device.
