Mixed Bed System

Mixed bed system
widely used in the food & beverage,ground & potable water, softening & industrial water

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.

(1)     Cation bed:
Built-in high-quality strong acid cation exchange resin, resin model: 001 * 7, the quality of the whole exchange capacity ≥ 4.5mmol / g, with excellent physical and chemical stability and good durable temperature performance, good selectivity, high exchange capacity. When RO produced water comes into the cation bed, the remaining cation does replacement reaction with cation resion, so the cation is further removed, removal rate can reach 90%.

(2)    Anion bed:
Built-in high-quality ion exchange resins, resin model: 201 * 7, the quality of the whole exchange capacity ≥ 3.8mmol / g, with excellent physical and chemical stability and good durable-temperature performance, good selectivity, high exchange capacity. The remaining anion does replacement reaction with the anion resin, So, anion is further removed ,to achieve the precise effect of removing salt.

(3)    Applications:

Ion exchange is widely used in the food & beverage, hydrometallurgical, metals finishing, chemical & petrochemical, pharmaceutical, sugar & sweeteners, ground & potable water, nuclear, softening & industrial water, semiconductor, power, and a host of other industries.
