Abstract: Disclosed is a system for recovering gas produced during electrodialysis of a saline solution, from gas entrained in an electrolyte solution circulating through anode and cathode compartments of an electrodialysis (ED) unit. In one embodiment, the system provides separate catholyte and anolyte towers within a closed, re-circulating loop between the cathode and anode compartments. Each tower comprises an inlet at which the entrained gas separates from the electrolyte solution and flows into the headspace. One can recover residual gases from the electrolyte solution in one more additional apparatus. Preferably, hydrogen gas is separated from the catholyte solution and, more preferably, further purified for use as a fuel source in alternative power generating devices, such as a fuel cell or bio-fuel generator, useful in the unit operations of a water treatment system.

Abstract: A stable concentrated dust control composition comprises a mixture of crude tall oil and vegetable oil emulsified in water. The dust control composition is completely organic, non-corrosive, non-flammable, non-toxic, ecologically safe, readily dilutable with water, safe to use, easy to apply to a desired surface and environmentally responsible. The water soluble formula may be designed to penetrate into the surfaces to bind with surface materials to create a dust free durable surface safe to motorists. The composition suspresses dust, so it is unable to be picked up and be carried away by wind and water, therefore preventing soil erosion and damage to field crops. The composition also reduces airborne dust that carries disease causing pollutants that are transported to distant communities.
