Abstract:
1. An acid mine water demineralization apparatus, comprising: two concentric cylinders configured such that the outer concentric cylinder surrounds about one third of the length of the inner concentric cylinder and wherein the internal area of the cylinders is divided into four sections comprising a water chamber, a gas chamber, a reaction zone, and an aeration zone, wherein the outer concentric cylinder is adapted to transport acid mine water to inlets on the inner concentric cylinder such that the water chamber comprises the space between the outer concentric cylinder and the inner concentric cylinder, wherein the inner concentric cylinder, having a closed end and a second open end, comprising the gas chamber, the reaction zone, and the aeration zone, wherein the first end, covered by the outer concentric cylinder, comprises the gas chamber having a porous stone to evenly distribute ozone gas into the reaction zone, wherein the reaction zone is formed in the interior of the inner concentric cylinder between the gas chamber and the aeration zone, and the inlets on the inner concentric cylinder comprise a plurality of sharp edged orifices between the water chamber and the reaction zone configured to spray acid mine water into the reaction chamber in the form of tiny streams, wherein the aeration zone is formed in the interior of the inner concentric cylinder between the reaction zone and the second end, and is separated from the reaction zone by a screen configured to break water into tiny droplets, and the inner concentric cylinder further comprises air vents at the aeration zone.
