Technical Merits
• Expenses of the electric power less than 100 J/kg per a product.
• Tolerance to the dissolved substance level in initial sea water or wastewater.
• Cost of the freshened water at level 1.5-3 $/m3.• High quality of the freshened water.
Confidential 8
Technology Description
• Initial sea water moves to a bottom part of the apparatus where it is agitated with the special agent under action of ultrasound. Thus the hot ice (clathrate) is formed.
• The formed suspension is moved by a pump in the evaporator of a freezing machine which is located inside of the apparatus and in which heat leaves, evolved in reaction.
• Hot ice crystals are separated from suspension on the filter located above the evaporator, and move upwards for washing.
• Cooled water moves in a crystallizing tank.
• Hot ice crystals are melted in a melter-condenser and fresh water is separated from special agent and it is transported to consumer.
Confidential 9
Advantages
• Conditions for carrying out this process are approximated to normal ones (pressure not above 3 atm. and temperature in the range from 0 to 30С).
• Simple hardware equipment.
• Water with the small contents of heavy isotopes Н2,H3 and O18.
Confidential 10
Advantages
• Low energy consumption on desalting of high salty water without its preliminary treatment.
Confidential 11
Experimental Results
• Energy consumption on producing of 1 kg of desalinated water depending on the degree of extraction of fresh water from an initial brine and its salinity
Confidential 12
Stage of Development
The pilot unit is developed. Properties of the clathrate are investigated.
Confidential 13
Next Steps for Development
Development of the commercial plant concept and patenting in the USA by the results of works performed (STCU project 3515).
Search of the partner in the USA together with the collaborator.
Development of the commercial plant (for example, IPP project).

Development Costs 2
• Demonstration plant at any location to produce 36,000 gallons/day [136 m3/day] or 40 acre-feet/year [49300 m3/year] if operated continuously
• Commercial plant at unspecified location to produce 3.6 million gallons/day [13600 m3/day] or 4,000 acre-feet/year [4.93 million m3/year]
• Commercial .plant at unspecified location to produce 7.2 million gallons/day [27300 m3/day] or 8,000 acre-feet/year [9.87 million m3 /year]
