New RFC Style Filters
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.
Whereas our GAC style filter uses “full flow” or longitudinal flow where the fluid saunters through a packed bed, traveling the full length of the filter cartridge from bottom to top (or one end to the other), our RFC filter uses a radial flow format where the fluid zips through the side walls of the filter, through the carbon or other medium, and then through the center core. (See figure.) The benefits of a full-flow filter are bigger bed volume, greater residence time of the fluid in the carbon, more-thorough removal of contaminants and longer life of the medium. The benefits of radial flow are greater flow rate with lower pressure drop, sufficient removal of contaminants for the applications in which the filter has been qualified, and higher recirculation rates in recirculating baths.
Whereas filters used in single pass applications must often remove as much contaminant as possible in a single pass (where the fluid makes only one trip through a filter), filters used in recirculating baths can often provide an enhanced benefit when they permit a higher recirculation rate. 100% removal in a single pass is usually not as important in many plating and electronics applications, because the baths used in these processes are cleaned-up by virtue of recirculation through a filter that permits high flow rates.
