1. Brief Introduction:
The product is a type of anion exchange resin with the quaternary amidocyanogen [-N(CH3)3OH] on macroporous styrene-divinyl benzene copolymer which is used in preparation for purity water and high-purity water, for purification of condensed water, for wastewater treatment and heavy metal recovery.
LH-202 resin series include four types: LH-201 is a kind of commonly used products, LH-201 FC for double room and fluidized bed system, LH-201 SC for bunk bed system, LH-201 MB for mixed bed system, especially for high-speed mixed bed used for condensed water purification
