e g fish farming odor suppression barriers for anaerobic processes and insolubiliztion of dissolved contaminants e g fe and mn ions for removal by filtration or sedimentation in view of the particularly good oxygen retention of liquids oxygenated by the present invention kept in containers a particularly advantageous new aerobic use of those liquids was discovered in accordance with a further feature of the present invention such oxygenated liquids can be advantageously employed as the fermentation liquor of all kinds of fermentation processes such as drug production or food processing by microorganisms microorganisms such as bacteria consume massive quantities of oxygen in the process of assimilating or breaking down waste the rate at which oxygen can be introduced into the biomass is a substantial limiting factor on how quickly a breakdown by oxygenation can be achieved the problem with known process technologies is that oxygen introduction by aeration is highly inefficient because air contains only 21 percent oxygen thus 79 percent of the energy used by aerators is wasted in pumping useless nitrogen therefore the use of highly oxygenated water in accordance with the present invention in such aerobic processes is expected to be about 5 times more efficient also to obtain thereby a like extent of energy efficiency improvement the dissolved oxygen content of water treated with embodiments of the present invention can be greater than 20 ppm can be greater than 40 ppm can be greater than 60 ppm can be greater than 80 ppm can be greater than 100 ppm can be greater than 120 ppm and can be greater than 140 ppm thus the.
