In this process, an FRP Degasser Column composed of FRP, with rubber linings is used. This has the purpose of removing carbonate ions by generating carbon dioxide. In a degasser tower, the air is blasted from the bottom to the top while a stream of water is poured from the top. FRP Degasser Column is filled with pall rings, which are used to increase surface area and break up the descending water column into a thin film and tiny drops. This is effective to use.
