  • Processes for producing hs using sulphur-reducing bacteria
    Patent number: 9085779
    Abstract: There is provided a process for producing H2S comprising: a) continuously providing an electron donor at a variable rate to a biosolution comprising sulphur-reducing bacteria; b) reacting elemental sulphur with HS? to from soluble polysulphide; c) providing said polysulphide to a bioreactor having the biosolution, thereby producing H2S gas in the bioreactor; and d) continuously removing H2S gas from the bioreactor, wherein an average rate of providing polysulphide to sulphur-reducing bacteria is equal to an average rate of polysulphide consumption by the sulphur-reducing bacteria.
    Type: Grant
    Filed: February 12, 2009
    Date of Patent: July 21, 2015
    Assignee: BIOTEQ ENVIRONMENTAL TECHNOLOGIES INC.

  • Selective sulphate removal by exclusive anion exchange from hard water waste streams
    Patent number: 8840793
    Abstract: The invention provides waste water treatment processes utilizing an ion exchange resin to remove sulphate anions, while adjusting the pH of the ion exchange loading solution with carbon dioxide gas. The effect of the resin loading reactions is that dissolved sulphate is replaced with sequestered carbon dioxide gas, in the form of dissolved bicarbonate, in the treated water and the cations are not removed from the solution.
