Isowater® Deuterium Oxide Refinery

Isowater® manufactures high-purity deuterium oxide (D2O) for commercial sale.

The company’s deuterium oxide refinery, which operates in accordance with Isowater’s ISO 9001:2015 accreditation, increases the deuterium concentration of below-market grade D2O. Isowater purchases this deuterium oxide following its use in industrial processes such as semiconductor manufacturing. These processes can reduce D2O purity to 50% and below.

Isowater’s proprietary refining technology enriches the downgraded deuterium oxide to a market-grade purity of 99.9%. The refining is done on behalf of customers or for sale to other customers. We also produce D2O at higher purity levels of up to 99.99% to meet individual customer specifications.

Environmental Sustainability

Our refining technology is designed to produce deuterium oxide at near-zero emissions. This represents a dramatic improvement over conventional hydrogen sulphide and ammonia-based enrichment processes.

Isowater’s refining process also exemplifies the principles of the “Circular Economy” by enhancing the environmental sustainability of both our company and our customers.

Optimized for Commercial Scale

Our D2O refining capability has been optimized for commercial-scale production. This advances us toward the production of sustainable long-term supplies that can meet the rapidly growing global demand for deuterium oxide.

Proposed Production of D2O from Natural Water

Separate from Isowater’s D2O refinery, our company has announced an intention to develop a 20 tonne/year deuterium oxide production plant. The proposed facility would produce sustainable long-term commercial supplies of de novo deuterium oxide from natural water, building on the company’s existing D2O refining technology.

The plant would be the world’s first deuterium oxide production facility targeting non-nuclear industrial and research uses of D2O. We are now in discussions to secure partners and customer agreements prior to reaching a final investment decision.
