Water purification. ELECTRICAL adsorption, work in a conductive liquid

It is known that the dipoles are drawn into the area with the highest electric field gradient.

 We know that even the non-polar molecules in an electric field is polarized and become dipoles.

 Therefore, in the air or gaseous environment around charged bodies are always there will be a cushion (zone) of the compressed gas. The mechanism of its formation is the same as the formation of a zone of adsorbed gases in uncharged substances. If we imagine that the adsorbent surface is a set of micro-charges, the fields are just on the surface out into the environment, the analogy is obvious.

 Imagine an electrical panel as adsorption two conductive grid, arranged one above the other. Served on the grid high DC voltage. To be specific on the verge of breakdown: in the air about 2 kV per millimeter. Between the grids, a zone of condensed gas. The gas pressure in this pillow will be greater than in the environment.

In addition, if the experiment is performed in a mixture of gases, the gases with high polarization, the molecules of which the best of the dipoles will supersede this pillow other components.
 So it is possible to enrich (or depleting) gas mixture necessary components).
 It is possible to apply this principle in water or other liquids.
 For this element mesh should be covered with a thin layer of dielectric insulator. This prevents breakdown and short-circuit the plates of the capacitor of the grid. The grid can be fused in polyethylene, in ceramics, at other facilities. Grid must be hermetically sealed to avoid contact with the liquid. Possible to produce networks of well insulated wire with a multilayer insulation.
 What will happen, what phenomena can be observed in the liquid at a voltage on the grid?

  In the liquid there ions. Positive ions rush to the negative electrode, the grid, negative ions rush to the positive electrode. But there is no current! The electrical circuit is broken - electrodes create an electric field between the plates, but the electrodes are isolated. Networks formed around the space charge of the ions and dipolar molecules of the liquid. Process immediately and will decay.
 Now suppose that there are impurities in the liquid, the particles are more atoms and molecules. Let this be a slurry of mud, algae, dust and rust from pipes, etc. They are the best dipoles than single molecules. They replaced all of the areas worst dipoles maximum field. They are seated honey individual conductors of different grids - that's where the maximum field.
 The process is not instantaneous.

 The lower the temperature of the liquid, the better - Brownian motion will not destroy the movement of these particles, which are on the verge of the macrocosm and microcosm.
 The higher the voltage, the better.

 The closer the grid, the better.
 Grid rigidly fixed, no movement.
 No jet streams. We do not know yet the rate of adsorption of these impurities at a given voltage and the temperature.
 When the process is finished, take out the grid, relieve stress, purify them, and they are ready for the new process.
 You can always delete the micropump structure between the plates.
 If the rate of adsorption of unwanted impurities is high enough, you can use the device with running water. Of course, calculating the necessary supply of fluid to the data grid (mesh) with the voltage at a given temperature and a given area networks.
 Used in various industrial processes possible.
 But arises as an obvious way to clean drinking water (and water for technological needs).
 What are the advantages of electric adsorption?
 Multiple, virtually infinite number of cycles. Almost infinite amount of processed liquids.
 Ability to manage the process of change in voltage.
 Unlimited opportunity to increase the active area.
 Negligible power consumption (if there is no current, the electrical circuit is always running in idle mode, the only thing that will determine the loss).
 Insignificant cost consumer devices.
 Opportunity for global use of water bodies.
 Alluring prospects ...
