摘要： A polar liquid mixture containing suspended or dissolved particles or solute is exposed to air or a hydrophilic surface. An exclusion zone having a reduced concentration of particles or solute is formed in the polar liquid adjacent to the interface with air or the hydrophilic surface. One or more fractions of purified polar liquid and/or concentrated particles or solute are collected. A sensor can provide feedback to the collector.

摘要： One or more brevetoxins or other toxins produced by red tides or other harmful algal blooms (HABs) are removed from a body of water by contacting an aqueous phase containing water, algae and one or more HAB-produced toxins with an organic phase, extracting the one or more toxins into the organic phase, and separating the organic phase enriched in the one or more toxins from the aqueous phase depleted in the one or more toxins. In some embodiments, the organic phase is comprised of vegetable oil, mineral oil, or other suitable oil. In some embodiments, an annular centrifugal contactor is used to accomplish the contacting, extracting, and separating. In some embodiments, the toxin-depleted aqueous phase is pumped back into the source of the aqueous phase, and the toxin-enriched organic phase is recirculated until a predetermined threshold concentration of the one or more toxins is met.

摘要： Processes for the removal of arsenic from aqueous solutions such as contaminated waters and process solutions are disclosed. Arsenic is removed from process solutions/effluents either by precipitation with a soluble iron compound, or solvent extraction and subsequent treatment with engineered materials, such as granular iron oxide. Arsenic may also be directly removed from arsenic contaminated ground and/or surface waters using engineered materials, especially by contacting ground and/or surface waters with silica, granular iron oxide and optionally natural zeolite in sequence. The treated solutions/effluents and waters may be released into the environment.
