Ultra pure water plants
Ultra pure water plant  is working with RO facilities combining with ion-exchange bed or EDI, ion-exchange bed is working by ion-exchange resin in electrolyte solution, can be used to wipe off all kinds of kation and anion, High purity water facility is a method to produce high purity water , which can not be substituted.
Ion-exchange equipment is of kation exchanging equipment and anion equipment. When the raw water passing ion-exchange pole, the kation and anion(HCO3-plasma ion)in water will exchange with H+ in positive resin and OH- in negative resin to get salt taking-off. The combination of kation and anoin will get the water higher purifie.
