  • Patent number: 6398968
    Abstract: Embodiments of the present invention relate to methods and systems for removal of contaminants from aqueous solutions. The methods and systems of these embodiments are particularly suited to removal of arsenic species as well as transition-metals, post-transition-metals, phosphates and other contaminants in aqueous solutions. The methods and systems of embodiments of the present invention provide for the addition of a reagent to a contaminated solution in combination with a pressurization process and a depressurization process. Contaminant particulates and solids produced in these processes may be removed by conventional separation techniques.

  • Patent number: 5858249
    Abstract: A continuous electrochemical processing method and apparatus for electrochemically removing arsenic contaminants from contaminated aqueous solutions comprising: a) identifying the ion(s) to be removed and their oxidation state, b) identifying the pH of the solution, c) constructing an electrolytic cell with a corroding iron anode and an inert cathode surrounding a reaction zone therebetween into which the contaminated solutions are passed, d) applying the required electromotive force to precipitate the desired ionic species, and e) physically removing the precipitates from the aqueous solution.
