Lanlang ® TC115FGD
Food Grade macroporous weak acid cation exchange resin
Used for softening, dealkalization and heavy metals removal for potable water and water for foods and beverages.
Lanlang ® TC115FGD Is a premium food grade macroporous weak acid cation exchange resin with polyacrylic matrix structure in standard Gaussian size distribution. TC115FGD 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. The part of its sodium form resin makes it has ability to remove heavy metals and without significant PH drop to water. Its high total and operating capacity, and its good kinetics make it is especially suitable to be used in small cartridges for pitchers.
