Method and apparatus for desalination of seawater
View Patent ↗A method and an apparatus for the modification of seawater, brine, or alike, to render it suitable for irrigation, industrial use, or for further treatment in a drinking water purification plant, as well as to extract desired substances from brines, such as boron, and to clear waste from mining processes, by reducing environment endangering contaminants, like petroleum hydro-carbons, or radioactive substances, as well as inactivating microorganisms and virus in biosolids, by means of exposing the substances to high-intensity macrosound, i.e., alternating mechanical energy radiation at (ultra-) sonic frequencies. The treatment enhances the separation of salt, or/and other desired materials, from the water, and activates in situ the adsorption of the materials on sorbefacient substances supplied to the desalination process in form of dust of pulverized, liquefied, or vaporized substances, or by elements (of walls) of treatment chambers, or filters. The separation of the adsorption material together with the adsorbed salt, or/and any other extract from the liquid, is accomplished by common techniques, such as sedimentation, decanter, filter, or (electrostatic) separator.
1. An apparatus comprising:
a chamber comprising:
a first inlet for a sorbent material,
a second inlet for a liquid to be treated, and
an outlet;
a rotatable comminuting grinder disposed in the chamber capable of producing an alternating mechanical energy radiation at ultra-sonic frequencies and modifying a liquid; and
a sieve disposed in the chamber wherein the grinder is disposed in the sieve.
2. The apparatus of claim 1 , wherein modifying comprises desalinating the liquid.
3. The apparatus of claim 1 , wherein modifying comprises decontaminating the liquid to meet health and environmental requirements.
4. The apparatus of claim 1 , wherein modifying comprises removing heavy metals, including radioactive elements, and liquids, or pathogens.
5. The apparatus of claim 1 , wherein the sorbent material comprises at least one of lignite (coal), or lava (volcanic rock), and pumice (igneous, extrusive volcanic rock).
6. The apparatus of claim 1 , wherein the sorbent material comprises one of solid phase, an element of the surrounding chamber, cell, or place, where the treatment is applied, and the sorbent material is one of liquefied, or vaporized phase.
7. The apparatus of claim 1 , further comprising a separator coupled to the outlet.
8. The apparatus of claim 1 , further comprising a dehydrator coupled to the outlet.
9. The apparatus of claim 1 , wherein the grinder comprises a pair of beater disks.
10. The apparatus of claim 9 , wherein the beater disks comprise a rotor and a stator and the rotor may be operated at on the order of 3800 revolutions per minute.
