How The AquaRain System Works... The AquaRain® system filters water in a very natural way using gravity to gently draw water down through our "cultured" ceramic stone in much the same manner as nature processes ground water through the earth. The microfine pore structure of our ceramic media will remove dangerous organisms such as protozoan cysts (Cryptosporidium, Giardia lamblia) and microscopic bacteria (E. coli, Salmonella typhimurium, etc...). Enclosed within the hard ceramic shell we have incorporated a concentrated bed of Granulated Activated Carbon (GAC) that contains a self-sterilizing metallic silver. The high performance silvered GAC bed will adsorb various organic chemicals such as MTBE and pesticides, remove chlorine compounds including carcinogenic halogens, and improve the taste and odor of the water. To the benefit of good health, our system will also leave unchanged the naturally occurring electrolytes and minerals found in your water. How Ceramics Work... Ceramic water filters work in three ways. First, surface sieving, much like a screen door, does not allow larger particles to pass through the outer surface of the filter. Second, ceramic filters operate as a depth media, providing a twisting, tortuous path like a maze, trapping contaminants within the walls (usually in the top .005" below the surface). Third, surface charge or adhesion, whereby contaminants that are small enough to penetrate the walls of the ceramic may cling to the walls like opposite polarity magnets attract each other. This surface charge is often greater than the force of the water flow that might otherwise dislodge the contaminant. This is particularly true with gravity or siphon-fed ceramic applications. Wall thickness is particularly important with regard to a ceramic’s performance as a depth media. The maze-like, tortuous path allows for filtration performance at an effective pore size that is much less than the actual median pore diameter of the diatomes from which the filter is made. As clogged filters are cleaned to restore flow, contaminants in the top .005" of surface material are removed. Gentle abrasive cleaning will gradually reduce wall thickness, making a reliable end-of-life indicator or gauge absolutely essential for easy determination of expended ceramics.
