It has also filed a Patent Cooperation Treaty (PCT) for BioteQ’s Selen-IX process.
BioteQ's proprietary nickel sulphide precipitation process, US patent No. 8,747,678 B2, relates to processes to selectively remove nickel from mine impacted waters. BioteQ currently uses the process at its water treatment facility in northern Quebec.
The proprietary sulphate removal process, US patent No. 8,551,340 B2, relates to processes to selectively remove sulphate from hard water waste streams. This process has been used in various testing and piloting projects to date.
BioteQ's application PCT/CA2014/05096 is for its Selen-IX technology which can selectively remove selenium from mine impacted waters and potentially other industrial waste streams. This international filing provides BioteQ with protection for the technology in 148 countries throughout the world and follows the filing of the US provisional patent application in October 2013. Since then, Selen-IX technology has been used in two pilot scale operations, first with a Canadian metals and mining company in 2013 and currently with another Canadian mining company.
"With the issuing of these two new patents and the filing of the PCT application, we have strengthened the patent portfolio for our suite of technologies," said BioteQ president & interim CEO, David Kratochvil. "These patents and the filing will support our business development efforts by emphasizing our commitment and capabilities in technology development in strategic areas of the overall mine water treatment market."
