Plasma formed in a fluid

A method and apparatus for generating plasma in a fluid. The fluid (3) is placed in a bath (2) having a pair of spaced electrodes (4, 6) forming a cathode and an anode. A stream of bubbles is introduced or generated within the fluid adjacent to the cathode. A potential difference is applied across the cathode and anode such that a glow discharge is formed in the bubble region and a plasma of ionized gas molecules is formed within the bubbles. The plasma may then be used in electrolysis, gas production, effluent treatment or sterilization, mineral extraction, production of nanoparticles or material enhancement. The method can be carried out at atmospheric pressure and room temperature. The electrodes may carry means to trap the bubbles in close proximity. Partitions may be present between the electrodes.

Process to obtain water bodies larger than 15,000 m3 for recreational use with color, transparency and cleanness characteristics similar to swimming pools or tropical seas at low cost

The invention discloses a process to implement and maintain water bodies larger than 15,000 m3 for recreational use, such as lakes or artificial lagoons, with excellent color, transparency and cleanness properties at low cost, which comprises the following steps:
    • a.—providing a structure able to contain a large water body larger than 15,000 m3;
    • b.—feeding the structure of step (a) with inlet water having iron and manganese levels lower than 1.5 ppm and turbidity lower than 5 NTU;
    • c.—measuring water pH, ideally it should be within a range lower than 7.8;
    • d.—adding an oxidizing agent to the water contained in the structure of step (a), with which a 600 mV minimal ORP is controlled in water for a minimal period of 4 hours and in maximal cycles of 48 hours;
    • e.—adding a flocculating agent in concentrations within 0.02 and 1 ppm with maximal frequencies of 6 days and cleaning the bottom of the structure of step (a) with a suction device to remove precipitated impurities from the bottom of said structure, together with the additional flocculants and;
    • f.—generating a displacement of surface water containing impurities and surface oils by means of the injection of inlet water according to step (b), which generates said displacement in such a way to remove said surface water by means of a system for impurities and surface oils removal arranged in the structure of step (a), which together with step (e) replaces traditional filtering.
The present invention also discloses a structure to contain large water bodies comprising a system for the removal of impurities and surface oils by means of skimmers and the suction device to clean said structure.
