Method of hydrodynamic evaporation
with the highest steam take off per m2 of evaporation surface among existing evaporation methods.


Intensified Evaporation

The key feature of the technology (know-how) lies in the intensified evaporation process which takes place on the surface of the supercavern - a large, up to 900 mm long vapor-air bubble that forms in the water flow behind the supercavitating element. Due to the reduced pressure in the cavity of this supercavern, the evaporation process is more efficient and less energy consuming. The hydrodynamic evaporation method provides the largest vapor removal per square meter of evaporation surface among existing evaporation methods - it reaches 1200 kg of steam per hour with a temperature difference of 6 - 12 ° C between the water solution and steam in the cavity.

Comparison to existing methods

General process description 

Water for purification/desalination is pumped through a preheater heated by condensing steam into an entry storage tank, from which it is fed through a heater at a temperature of 110 - 115 ° C under a pressure of 0.5 MPa to a hydrodynamic evaporation device. In it, as a result of the flow of water at a certain speed behind the supercavitation elements located in the stream, supercaverns arise. The drip-steam mixture is removed from the cavities through the branch pipes and is separated in the separator into steam and condensate. The droplets are collected in a manifold and returned to the reservoir. The steam is sent to a condenser, where it is cooled by salt water, which enters the system, and condensed. Condensate is collected in clean water tank. Water treated during the first evaporation cycle is repeatedly returned to the heater inlet and is pumped through the device. As a result, the concentration of salt in the solution increases. The concentrated brine solution is drawn from the system into a brine storage tank.

Key advantages

  • The flow balance is determined in the following quantities: from 100 m3 of seawater, 94 m3 of demineralized water and 6 m3 of concentrated salt solution are obtained. It is possible to obtain a dry residue of salts.

  • Consumables (such as membranes, cartridges, filters) are not used in the desalination of seawater and wastewater treatment.

  • The technology allows obtaining high-quality water with minimal energy consumption from various sources (ponds, rivers, lakes, underground sources, salt lakes, seas).

  • The concentration of organic matter in the incoming water can be up to 100,000 mg/l and the salt content up to 70,000 mg/l.

  • Electrophysical forces can destroy toxic substances, microflora and organic impurities.

  • The technology prevents the formation of organochlorine compounds (dioxins).
