    Abstract: Disclosed is a highly efficient method of and apparatus for transferring atmospheric oxygen to water by aerating a body of water at or near its edges to generate in the water''s upper stratum converging currents which move toward the central section of the body of water. Conventional pumping, brush-type or turbine-type aerators can be used, but for best results a novel apparatus of our design is used. Preferably, the converging currents are directed slightly off-center so that a whirlpool is formed at this section. Alternatively, a contaminated body of water can be aerated at a region about midway between the central section of the body of water and the periphery of the body of water to generate in the water''s upper stratum some converging currents which move toward the central section of the body of water and some diverging currents which move toward the periphery of the body of water.

    Abstract: Oil, solid particles such as biological slime and floating debris etc. are removed from water by an apparatus including endless chain means made up of a series of interconnected foraminous chambers holding a regenerable porous filter material such as polyurethane. Preferably the filter material has an outer large pore section and an inner small pore section. A plurality of buckets are attached to the chain means, and as the chain means moves through a closed loop path, these buckets catch debris and dump it into a holding bin. Simultaneously, the filter material absorbs surface and subsurface oil and the like from water traveling through the filter material. The filter material is regenerated by squeezing the filter material to release the oil.

    Abstract: In this system, waste-water, particularly refinery waste-water, is treated in a series of lagoons in which thrive microorganisms that feed on contaminants in the waste-water. The system is characterized by mobile aerator apparatus moving across the lagoons'' surfaces. These apparatus introduce air into the lagoons and churn surface water, and they have means which direct at least some of the churning surface water towards the lagoons'' bottoms. The underwater turbulence scours the lagoons'' bottoms and provides a way of controlling sludge deposits.
