Mechanism of Formation of Electrolysis Bubbles in Water and the Use of their Properties for the Development of New Technologies in Microgravity

Michael Shoikhedbrod

Abstract


The author's earlier theoretical description of the mechanism of formation of negatively charged electrolysis hydrogen bubbles and control of their size under terrestrial conditions confirmed experimentally, made it possible to conclude that negatively charged bubbles of electrolysis hydrogen, floating up in a fluid, encounter solid particles on their way with dimensions much larger than bubbles induce a positive charge on the surface of a solid particle. As a result of the action of the arising electrostatic force of attraction and the force of surface tension, a complex is formed: a solid particle, hung with negatively charged hydrogen bubbles, with a significantly increased lifting volume. Under terrestrial conditions, the formed complexes, due to their increased volumes, float to the surface of the fluid because of the action of the Archimedes force, and solid particles are separated from the fluid. The conducted studies permitted to use of these unique properties of electrolyzed hydrogen bubbles for cleaning of industrial wastewaters and sewage, clarification of juices and vines, juice, and unicellular alga concentrates production. The separation of solid inclusions from fluid under microgravity conditions plays a decisive role in the purification of fuel and special fluids from solid inclusions in the life support and power supply systems of the International Space Station. However, under microgravity conditions, the Archimedes force is absent and it is necessary to look for new applications of the properties of electrolysis hydrogen bubbles for the separation of solid inclusions from a liquid under these conditions. The paper discloses the mechanism of formation of negatively charged electrolysis hydrogen bubbles and the use of their properties for separation solid inclusion from fluid under microgravity conditions, confirmed experimentally, permitted to establish the movement of negatively charged electrolysis hydrogen bubbles in a fluid in a horizontal direction towards to the anode due to the arising electrostatic force of attraction and the formation of negative shield complexes: hydrogen bubbles + solid particle, and the movement these complexes towards to the positively charged anode. In this case, the main role in the separation of solid inclusion from the fluid is played by the conical shape of the separator, which allows draining all liquid: purified in the near-cathode zone and concentrated by solid particles in the near-anode zone, into different ampoules. The conducted research permitted the construction of a special concentrator-separator capable of operating on the International Space Station.
