What is the difference between reverse osmosis (RO) and ultra violet (UV) purification?
A10: Both of these technologies address pathogens—bacteria and viruses, but in a different manner. Ultra violet light is a wavelength of light that will kill pathogens. (Note: The MMP has a safety feature built-in whereby if the UV lamp goes out, the water going through the UV filter is automatically shut off. No non-treated water will pass through the UV filter. However, since there are two parallel redundant filtering systems in the MMP, the other UV unit will continue to provide potable water—but at half the normal production.) The reverse osmosis technology is the passing of water through a semi-permeable membrane to remove viruses, bacteria, dissolved solids, organics and salts. The product water that exits the membrane is potable. RO systems use a lot of energy to force the untreated water through the membrane. This is why our UV (Fresh Water MMP) can produce an average of 30,000 gallons per day (GPD) of potable water, versus 6,000 GPD for the Brackish purification system and 3,0
