Abstract: Acid mine demineralization methods wherein the acid mine drainage is neutralized, clarified, and forwarded to a microfiltration unit. The so filtered drainage water is then forwarded to a reverse osmosis unit. 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.

Abstract: A method of controlling the deposition of silica containing scales and their adhesion to surfaces in contact with an aqueous system is disclosed which comprises adding to the aqueous system a water-soluble or dispersible hydrophobically modified polyether polymer.

Abstract: Methods of enhancing performance of a semi-permeable filtration membrane such as a polyamide R.O. membrane. A water soluble polymer is brought into contact with the membrane structure and is characterized by the Formula I wherein E is a repeat unit remaining after polymerization of an ethylenically unsaturated monomer or mixtures thereof; R1 is hydrogen or C1-C4 alkyl; R2 is C1-C6 alkyl, C1-C6 alkylene, di-hydroxy substituted C1-C6 alkyl, di-hydroxy substituted C1-C6 alkylene, aryl, or mixtures thereof; n is 0 to about 100; R3 is OH, SO3Z OSO3Z, PO3Z2, OPO3Z2, CO2Z, or mixtures thereof; Z is hydrogen or a water-soluble cation; and the mole ratio c:d ranges from about 30:1 to 1:20 respectively.
