Abstract: A method for generating a hydride gas of metal M1 in an electrochemical cell comprising a cathode comprising metal M1, a sacrificial anode comprising metal M2, an initial concentration of aqueous electrolyte solution comprising a metal hydroxide, M3OH, wherein the sacrificial metal anode electrochemically oxidizes in the presence of the aqueous electrolyte solution comprising M3OH to form a metal salt, and the hydride gas of metal M1 is formed by reducing the metal M1 of the cathode. The method comprises the steps of determining solubility profile curves of the metal salt as the M3OH is consumed and the metal oxide is formed by the oxidation reaction at various concentrations of M3OH; determining a maximum concentration of M3OH that, as it is consumed, does not yield a concentration of metal salt that precipitates out of the electrolyte solution; and choosing a concentration of M3OH that is in the range of at and within 5% less than the maximum concentration of M3OH to be the initial concentration of M3OH.

Abstract: A system for separating suspended and dissolved materials in a fluid having a pH offset from neutral is disclosed. It employs a plurality of stacked, generally flat treatment beds each having a surface angled downward for receiving the fluid. Since the fluid is spread over a large surface, its velocity slows causing suspended materials to drop out of the fluid as a sludge.

Portions of the beds may be isolated and the sludge collected resulting in a fluid having substantially less suspended and dissolved materials at a pH and temperature closer to normal. This invention is especially useful for remediating acid mine drainage.
