Our new RFC style filter has found applications in electro-plating for removing organics from plating solutions, and in drinking water filtration for reducing "CTO" or chlorine, taste and odor. For electroplating, we have an anthracite based activated carbon, and for drinking water customers we recommend a coconut carbon based GAC (granular activated carbon). We can also place other media in these filters for removing or reducing targeted contaminants. Our new RFC-FE Radial Flow Iron Reduction Cartridge helps to eliminate brown and orange stains in toilets, sinks, tubs and clothes in washing machines. The specialized media utilized will remove iron, manganese and hydrogen sulfide (H2S) from water.
