The process is based on the natural ability of water streams to self-purification and utilizes water stream turbulence and resulting air bubbles formation and comprises pollutants flotation directly from the stream, further froth collection by a froth entrapping element and polluting agents removal or movement with the froth with further precipitation at designated locations.

Description
A METHOD OF WATER STREAMS SELF-PURIFICATION
The present invention relates to water treatment for preparation of drinking, technical or other water by water streams clean-up from pollutants directly at the site. Water streams mean any creeks, rivers, springs or raw water transported by channel or pipe for treatment.
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. 4,690,756, dated Sept.l, 1987, an apparatus for a flotational removal of pollutants, nutrients, toxins from natural bodies of water and wastewater in situ is proposed. A gas is introduced through a diffuser into a body of water to form bubbles.
In the patent, U. S. Pat. No. 5,122,165, dated Jun., 1992, a process 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.
In the patent U. S. Pat. No. 5,482,620 dated Jan.9, 1996, a permeable ditch underwater water purification apparatus purifies source water using a granular filter layer. This apparatus includes impermeable ditch walls on a tapered bottom.
In nature running water is o8en mixed with air, froth on the water surface is abundant especially after some obstacles present at the stream bed, that causes the turbulence. 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 speed and character of flow, etc. Froth collection and possible removal or movement to designated locations 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 and is released forming further air bubbles because of naturally occurring changes in water speed along the water stream. To promote a formation of air bubbles into running water artificial changes in water speed could be arranged.
To collect flotational froth, one, two or any necessary number of froth collectors are installed on the top of the water stream along water current, at one or several sites where froth is collected. Froth collectors is any object installed at the water stream or floating there, the said froth collectors entrap all or part of the froth from the water. The froth collector may be constructed and placed in a way that allows the froth to be concentrated at the selected sites.
The froth further could be removed from the said froth collector, it could be pumped to froth collecting tanks, ponds or treatment plant.
In order to avoid the release of the aggregates of contaminating particles from the froth into water, the construction of the froth trap could include an elemem that would entrap the said aggregates, the said precipitates composing contaminants could be fi~rther removed or treated.
It could also be that the construction and installation of the flotational trap with or without the said precipitate entrapping element enables the froth to be moved to certain sites of concentration by surface water movement, for example, to the bank or banks of the water stream. If the velocity of water at such sites is low or only the surface layer is moving at all after decay of air bubbles contaminating aggregates would be accumulated at the bottom of such sites. It could also be that at such sites there would be an opening in the flotational trap allowing the froth to ~
moved downstream with the movement of surface water. In a case if this water slowly movement takes place along properly designed channel, the aggregates would precipitate to the bottom of the said shallow channel and could be further removed.
The said channel could have specially designed elements at the bottom (like ribs) that favors precipitation. The said channel should end downstream releasing surface water and surfactants into the main body of water.
