Description
FLOTATIONAL CLEAN-UP OF RUNNING WATER
The present invention relates to environment protection by flotational clean up of running water from pollutants. Running water means rivers, creeks, springs, small streams, industrial and waste streams, mining effluents, sewage and any other streams.
In the patent, U.S. Pat. No. 4,244,819, dated Jun., 1981, a floating anti-pollution barner for combating water pollution is disclosed. The floating pockets of the barrier, the openings of which are downwardly disposed, are given their shape and kept in shape by masses of a material which is lighter than water.
In the patent, U. S. Pat. No. 5,122,165, dated Jun., 1992, a process system and apparatus for removal of toxic volatile compounds and surfactants from a contaminated liquid stream is described. This process system involves liquid pumping; gas purification by a foam collector; etc.
Flotational separation techniques, especially the techniques such as those in U. S.
Pat. No. 5,306,422 dated Apr., 1994 and U.S. Pat. No. 5,538,631 dated Jul., allow to treat the waste water.
In the patent U.S. Pat. No. 5,840,156 dated Nov., 1998, a froth flotational process for deinking wastewater using multiflow pressurized deinking module is disclosed.
To the best knowledge of Your Petitioners all currently existing methods of water treatment utilize diverting water to some treatment facility and there is no method acting directly at water in rivers, creeks, springs etc. Meantime in nature running water is often mixed with air, froth on the water surface is abundant especially after some obstacles present at stream bed, where turbulence occurs. These elements are also characteristic to flotational process and the basic idea of proposed invention is to utilize naturally occurring flotational process of pollutants or to enhance this flotational process by adding surfactants, providing changes in water speeed and character of flow, etc. Froth collection and removed are thus the next step in a clean-up process.
For performing flotational processes, this method uses flotational agents that are either already present into the water as a result of industrial or naturally occurring biological activities or flotational agents are added to the water. Air is taken into the water stream arid is released forming further air bubbles because of naturally occurring changes in water speed along the water stream. Turbulent character of water stream ensures capturing of polluting agents by air bubbles.To promote air delivery into running water either artificial changes in water speed are arranged or air is delivered directly by pumping it into the water wherein the air bubbles form air curtain across water current and create turbulence, or air bubbles and turbulence are created indirectly by pumping water saturated with air under high pressure (dissolved air flotation).
To collect flotational froth, one, two or any necessary number of froth collectors 40 are installed on the top of the water stream. Froth collectors protrudes from one bank of the stream to the other, thus making it impossible for the froth to by-pass the froth collector. The froth collector may be constructed and placed in a way that allows the froth to be concentrated at the selected points.
The froth further has to be removed from the said froth collector, it could be pumped to froth collecting tanks, ponds or treatment plant.
The flotational clean up of spills into running water where flotational agents are added to contaminated spots of water and flotational traps are installed downstream to intercept the contamination, where flotational trap is the air or water saturated with air delivering pipe installed across the stream, and froth collectors installed further downstream.
