New dissolved oxygen technology from New Brunswick

Tor-Eddie Fossbakk  PurGRO2 is both a method and a system designed for use in aquaculture in order to improve and to optimize the raising, growing out and live shipment of fresh water and salt water species. It is comprised of low-pressure and high pressure components, which may be employed separately or in conjunction with one another. This improvement typically characterized by increasing growth rates, higher stocking densities and reduced mortality, is brought about by employing inVentures Technologies’ innovative Gas inFusion Technology to optimize and enhance the ‘atmosphere’ at each stage in the aquaculture process. What to Expect From a PurGRO2® System § Higher tonnage of fish produced per year due to higher growth. § Increased stocking density if desired because of the ability to manipulate atmospheres. § More available dissolved oxygen (8 mg/L +) results in fish that are less stressed out and less susceptible to disease. § Low energy required per kg of oxygen delivered at high DO levels. § Ability to increase the efficiency of existing oxygenation systems. § Effective removal of ammonia § Improved bioreactor efficiency The equipment, just like the technology, is quite simple, small and effortless to operate, according to the company.
