1. Brief Introduction:
The product is a type of anion exchange resin with the tertiary amidocyanogen [-N(CH3)2] on macroporous styrene- divinyl benzene copolymer which is used in preparation for purity water and high-purity water, especially for treatment of water with high salinity and organic matter content and also can be used for wastewater disposal containing chrome and sugar solution discoloration
LH-301 resin series are made up of three types, LH-301 is a kind of commonly used products, LH-301 FC is widely used in double room and fluidized bed, LH-301 SC is applied to bunk bed system.
Combining LH-301resin series and strongly basic anion resin can improve average exchange capacity and water exit quality, reduce the specific amount of regenerant and protect strongly basic anion resin from polluting by organic matter.
