Arsenic Remover works on adsorption principle and is able to reduce arsenic content of water below drinking water limit values selectively. It employs a simple process that flows pressurized water through a fixed bed pressure vessel containing the ferric oxide. As the contaminated water passes through the media, arsenic is adsorbed and removed to a level below 10mg/L. A typical arsenic remover for achieving a less than 10 ppb arsenic level for small-scale municipal water supplies requires an average pressure-drop of about 3 pounds per square inch (psi).
