220Na-Indion original strong acid cation exchange Resin
Indion 220Na cation exchange resin root is strong acid, colloidal particulates, which are produced from the process of high-molecular compounds chemical sunfon coincidence from polystyrene.
Indion 220Na have size particles evenly, porosity ensures high cation exchange capacity. With the physical-chemical characteristics and optimal thermal durability, Indion 220Na be used to soften water, reduction of pollutants or ammonium.
As the exchange of saturation can regenerate by solution of NaCl, HCl or H2SO4 (depending on the purpose of use to soften or eliminate minerals) in the same or reverse the water flow.
Indion 220Na is Ion Exchange Group's products, manufactured in India from 1964 and was exported to the United States, Britain, Japan, Russia, Thailand, the Philippines, Maylaysia, …
The durability of use: at least 3 years if done in accordance with the manufacturer's process.
Indion 220Na are applications in the UV water treatment system.
