Product Details

Lanlang ® TC113FGD Is a premium food grade macroporous weak acid cation exchange resin with polyacrylic matrix structure in standard Gaussian size distribution. TC113FGD is in compliance with US FDA 21 CFR 173.25 and NSF/ANSI 61 qualified with WQA Gold Seal Certificate. It can be used to remove both of temporary hardness and alkalinity (carbonate, bicarbonate and hydroxide) from water. This process produces carbon dioxide from bicarbonate to give pleasant taste to the treated water. Its high total and operating capacity, and its good kinetics make it is especially suitable to be used in small cartridges for pitchers.
