Headworks to provide MBBR technology for wastewater treatment at Canadian gold mine14 February 2013
US-based advanced wastewater treatment processes and equipment provider Headworks International has secured a contract with Claude Resources, to provide its moving bed biofilm reactor (MBBR) technology to treat underground mine water at the Seabee gold mine in Northern Saskatchewan, Canada.
Headworks International, which won the contract through its fully-owned subsidiary Headworks BIO, has not disclosed the financial terms of the deal.
Claude resources,a Canadian gold exploration and mining company, chose Headworks' MBBR technology as a wastewater treatment process to reduce the amount of ammonia in the mine effluent.
Under the contract, Headworks will deploy its high-surface area ActiveCell 920 media and supply aeration grids, retention screens, and two blowers at the mine.
During the wastewater treatment process, the influent water will be first treated to remove suspended solids, and then heated to 10°C, before releasing the effluent safely into a large pond.
Headworks president and CEO Michele LaNoue said the contract demonstrates that the MBBR technology can be used for diverse applications.
"We are confident that we will work within the time constraints and deliver this project on schedule with the ultimate goal of a successfully operating treatment system accomplished," LaNoue added.
The MBBR technology is a fixed film wastewater treatment process that uses thousands of polyethylene biofilm carriers, which supports the growth of biofilm.
The carriers move freely in the reactor to oxidise ammonia nitrogen in the wastewater, while the oxygen is delivered to the carriers through course bubble aeration and keep the carriers mixed and suspended.
Media is retained in each reactor through the stainless steel retention screens.
