Equipment required:

10,000 gpd vapor compressor

1000 gallon recycle tank
500 gallon brine tank

Useful information

1 cubic foot water = 7.48 gallons

1 gallon water = 8.34 pounds

1 cubic foot of water weighs approximately 62pounds

1 cubic foot of concentrated solids to 5% moisture weighs approximately 100 pounds

Sand w/ Gravel, wet = 125 pounds per cubic foot

Sand w/ Gravel, dry = 108 pounds per cubic foot


 

10,000 gpd at 1000ppm = 8,340 pounds solids per 1,000,000,000 gallons (83.4 pounds of solids per 10,000 gallons).


A 10,000 gpd vapor compressor generates 9,000 gallons of distilled water and 1,000 gallons of reject brine water at 10,000 ppm if the influent is 1,000 ppm.

 

This 1,000 gallons of 10,000 ppm reject water must be compressed , yielding 900 gallons of distilled water and 100 gallons of reject brine at 100,000 ppm (84 pounds).

 

900 gallons of 10,000 ppm reject brine should be added to the 100 gallons of 100,000 ppm reject brine water in the 1,000 gallon tank, producing 1000 gallons of reject brine water at 15,000 ppm (approximately 150 pounds solids).

 

The 1000 gallons of reject brine water at 15,000 ppm will be compressed to 100 gallons of 150,000 ppm reject brine.

 

900 gallons of 10,000 ppm reject brine should again be added to the 100 gallons of 150,000 ppm reject brine (approximately 225 pounds solids) This batch should be compressed and stored in the 500 gallon brine tank for solids recovery.

 

The final reject brine is at 210 degrees Fahrenheit and will cause rapid evaporation. Supersaturation may be achieved with no additional heat.

Vapor Compression Water Distillers processes more clean water and has the least amount of reject brine of any water purification equipment on the market.

Water heaters for desalination and solidifying constituents in water for solid disposal

When you don't have enough sun and you want to remove salt from the reject water you can use a gas water heater to dry the salt and minerals from your reject water.

 

 

No permitting for discharge stream disposal!

The cost and time of discharge permitting and a legal war with environmentalists will pay for a 500,000 gallon a day water purification system and YOU CAN BE FLOWING WATER IN LESS THAN 90 DAYS.

Why we use Vapor Compression Distillation (VCD) technology:

The most economical source of quality, distilled water, is VCD. VCD can handle the broadest spectrum of constituents however VC requires energy. The land and capital cost savings by use of VC distillation is significant when used for water heating with SunDragon technology.

 

 

 

SunDragon works best with vapor compressions hyper-saline brine discharge at 212 Degrees F

 

Pounds of Salts and Solids per 1 Million U S Gallons of Water Desalinated

Based on ppm/tds


Brackish: 1,000ppm = 8,335.8822 Pounds of Salt

Brackish: 5,000ppm= 41,679.411 Pounds of Salt
Highly Brackish:15,000ppm = 125,038.234 Pounds of Salt
Saline: 30,000 ppm = 250,076.468 Pounds of Salt
Sea Water: 40,000 ppm = 333,435.291 Pounds of Salt
Brine: 300,000+ ppm = 2,500,764.681 Pounds of Salt
