Abstract
A method and apparatus are described for improving the aerobic and nutrient quality of a body of water in a reservoir which contains undesirable dissolved salts and harmful microorganisms, by incorporating into the water effective amounts of oxygen-generating microorganisms, microorganisms with an affinity for dissolved salts, and enzymes and nutrients for the microorganisms, and maintaining effective concentrations of the microorganisms, enzymes and nutrients in the water while the microorganisms convert the dissolved salts into insoluble salts which precipitate and to remove or deactivate the harmful microorganisms. The apparatus includes supply tanks containing water slurries of the microorganisms, enzymes and nutrients, conduits to convey supply water, slurries, enzymes and nutrients into the water, an optional spray to aerate some slurry as it sprays onto the surface of the water; and pumps in the conduits to maintain such effective concentrations of the microorganisms, enzymes and nutrients in the water. The system may be controlled by a computer. Typical of the applications for which this invention can be used is the rejuvenation and enhancement of irrigation water supplies …
