Lead Removal
Lead exposure in the body can cause irreversible damage to the kidneys, brain, nervous system and red blood cells. Ignoring lead contaminated drinking water can eventually cause irreversible health effects and even death. Lead contamination in drinking water is usually due to plumbing corrosion in service lines, lead solder and brass fixtures. Water characteristics promoting the corrosion of water include low pH, low total dissolved solids, high water temperature and high concentrations of dissolved gases such as oxygen or carbon dioxide. Because of its acidic pH and low dissolved solid content such as calcium and magnesium soft water tends to be more corrosive than hard water. The two “point of use” technologies successful at removing lead from water are reverse osmosis and activated alumina. Activated alumina is a porous granular form of aluminum oxide possessing a large surface area and while amphoteric alumina for lead removal works best under acidic conditions, as in the range of pH 5.5 to 6.0. Smaller particles have greater surface area. Surface area as defined by particle size impacts on sorption capacity and rate of lead removal. AL 2000 activated alumina from DAI provides the simplest, most cost efficient method for the removal of lead from the water supply.
