METHODS DEMINERALIZATION acid mine WATER

摘要

Acid mine demineralization methods wherein the acid mine drainage is neutralized, clarified, and forwarded to a microfiltration unit (34). The so filtered drainage water is then forwarded to a reverse osmosis unit (48). The permeate from the reverse osmosis unit is characterized by reduced sulfate, silica, calcium, aluminum, iron, magnesium, and manganese levels. Additionally, improvement in reduction of total dissolved solids is noted.
