H2O Innovation Inc, a designer of water treatment solutions based on membrane filtration technology, has announced its largest ultrafiltration contract to date.

The contract with the City of San Diego, California, USA, is worth C$9.1 million. It involves the design, manufacture and commissioning of a 12-train hollow fibre ultrafiltration system that will treat 40 MGD (151,416 m3/day) of nitrified, tertiary filtered, ozone-enhanced biologically active filtration wastewater.

This contract brings the Canadian company's project sales backlog to $56.8 million.

The San Diego North City Pure Water Facility is designed to address the need for a new, locally controlled, drought-proof water supply. A 1.0 MGD water purification demonstration facility was developed in 2009. As a result of this demonstration project and successful pilot testing, the city awarded the contract to H2O Innovation.

It follows a number of US contract awards this year. In June, the company announced two new wastewater projects in the US, together worth a total of $3.9 million, and in April six US contracts worth C$4.8 million.

Headquartered in Quebec City, H2O Innovation operates three manufacturing facilities: Ham-Nord, Quebec; Minneapolis, Minnesota; and San Diego, California. It also maintains regional offices in Calgary and Burlington in Canada, and San Diego in the US.
