HIGH PRESSURE SPRAY EVAPORATION IN LOW VAPOR PRESSURE ENVIRONMENT ENABLES TREMENDOUS SAVINGS
IN CONSTRUCTION AND OPERATION EXPENSE
Spray Distillation Process Enables Ezekiel's Water Project Desalination Plan
Henry Lloyd, President and CEO of AquaSonics International, Inc. says they have done it. Their
Rapid Spray Distillationİ ( RSDİ) process desalinates water at a fraction of the cost of current
methods. RSDİ is based on the principle that saline water is ejected at high velocities in a
patented process. Rapid evaporation occurs and is condensed into drinking water. Dissolved salts
precipitate as a solid phase and are removed. This single stage process reduces disposal costs
and provides raw materials."
The RSDİ technology achieves in one step what current reverse osmosis and multi-stage flash
requires multiple steps to accomplish, and is three times more efficient in processing sea-water.
The thermodynamics and aqueous chemistry of the process is extremely straightforward. Bench
testing shows 95% efficiency in recovery of fresh water and separation of salts in a single
stage versus 36% efficiency for other processes.
Because of the simplicity of the process construction costs are estimated to be at least half of
present multi-stage flash and reverse osmosis systems. Operating costs are a fraction of
traditional technologies because of the high efficiency of RSDİ.Operating and maintenance costs
are also a fraction of traditional methods because of the almost complete absence of moving
parts. Aquasonics believes that three times the volume of fresh water can be generated with for
the same cost as traditional methods.. The projected impact on total costs would be to reduce
the overall expenditure for RSDİ desalinated water to one-quarter the cost of current methods,
making fresh water available where it is now scarce.

IDE is internationally recognized as a pioneer and leader in the delivery of Thermal Distillation plants. IDE's Low
Temperature Thermal Distillation units are available in two versions, energy supplied either by a unique electrically
driven mechanical compressor - Mechanical Vapor Compression (MVC), or by low pressure steam - Multi Effect Distillation
(MED). These systems are capable of producing boiler feed water from sea water in a single step.
Latest technology for reverse osmosis desalination is an alternative
approach for Ezekiel's Water Project desalination process.
