Answer: DI Cartridges and In-line DI Filters: Deionization removes ions (heavy metals or salts) dissolved into the water. RO membranes: Membranes remove bacteria, virus, metals, salts (ions). Carbon Filters: Carbon block filters absorb chlorine, chemicals and filter particulate matter. Sediment filters: Sediments filter out particulate matter only. The top quality water purification system is built […]

Answer: RO systems are capable of removing certain biological contaminants such as Cryptosporidium and Giardia.  The pore size of the RO membrane along with the amount of pressure applied to the water will generally determine the rate of reduction of such contaminants.  The Water Quality Association (WQA) states,  that while RO membranes are reliable for […]

Background Soluble chemical compounds, when dissolved in water, become ionized; that is, their molecules dissociate into positively and negatively charged components called ions. Consider common table salt, sodium chloride. In its solid form, this compound consists of one sodium atom (Na) and one chlorine atom (Cl) tightly coupled together (NaCl). When dissolved in water, however, […]
