• BrineRefine technology to remove scaling ions, enabling downstream processing at extremely high recoveries;
• A novel real-time calcium sensor capable of operating on challenging flows (we developed our own after off-the-shelf sensors failed to meet requirements);
• Ultra high-pressure reverse osmosis (RO) spiral wound technology, operating at 1,800 psi (120 bar); and
• Expert engineering and production that integrates all technologies into a tidy, intelligent package capable of operating on variable industrial flows.

Saltworks developed and delivered an EOR produced water pilot, that reliably desalted the returning produced water. This saves the client notable chemical costs: more than the cost of water treatment, in some cases. Saltworks can run a project assessment to evaluate each specific case.

In addition to the cost savings, the following benefits may be achieved:

• Water is recycled in a closed loop, rather than discarded. This reduces both water loss to disposal wells and freshwater withdrawal from the environment
• Higher quality water is re-injected, with lower hardness and suspended solids that can plug the formation
• Less trucking and GHGs associated with chemical delivery to site, or hauling waste produced water off site when required

“The AirBreather is a novel evaporation alternative that offers both lower cost and risk,” said Henry Tsin, Saltworks’ Technology Director. “There is zero direct contact of produced water with atmosphere which removes the risk of air emissions – and no need to manage distilled water which removes a lengthy and costly permitting process.”

The pilot included a full scale Saltworks’ Flex EDR Selective Stack, which acts as a “chloride kidney.” Within the stack, Saltworks’ novel monovalent selective anion exchange membranes pull chlorides out of the FGD wastewater under a DC electric field. Outside of stack, a robotized plant enables the process while adjusting to variable water quality and providing valuable data to the operator. The results will be presented at future conferences or contact Saltworks to learn more.

“Our government’s investment in this revolutionary clean innovation, developed right here in Canada builds on our plan to strengthen Canada’s economy though innovation,” said The Honourable Harjit Sajjan, Minister of National Defence. “This investment will not only help the oil and gas industry reduce wastewater and greenhouse gas emissions, it also will reduce costs for the industry, helping to maintain jobs and create new ones. Innovative companies like Saltworks demonstrate how a strong economy and a clean environment go hand-in-hand.”
