Abstract
We are developing a water processing system for the removal of arsenic from geothermal water. We adopt the coprecipitation method of Fe (III) hydroxide, in which As is adsorpted to the flocks of Fe (III) hydroxide, and the High Intensity and High Gradient Magnetic Separation (HIHGMS) by superconducting magnets to extract the flocks. We demonstrated that the method reduce arsenic to 0.015mg/L that closed to the environmental standard in Japan, from 3.4mg/L and we purified a large amount of water at high speed. We also describe an estimate of a feasible plant for removal of arsenic in the geothermal water for public use.
