Solar desalination or salt recovery may be recovered using free sunshine but that is where free ends. As in any water recovery project the cost of traditional equipment for the processing commercial quantities of clean water and the cost per gallon of water produced is competitive and the technology is proven and works well is situations where environmental concerns are minimal. ZERO LIQUID DISCHARGE AND REJECT BRINE DISPOSAL COSTS WILL HAVE GREATER IMPACT THAN ENERGY PURIFICATION COSTS IN THE DESALINIZATION OF SEAWATER OR WASTEWATER   Zero Liquid Discharge is not free and costs are best controlled by combining the Vapco vapor compression system for first phase desalination/concentration and SunDragon Zero Liquid Discharge Salt Factories for salt and constituent recovery. The current practice of discharging reject brine to the sea is being disputed and challenged by many environmentalists. They claim that reject brine is harmful to the environment and marine life. It is only a matter of time before the environmentalist win. Ocean disposal of reject brine is also under heightened scrutiny by governments world wide as evidenced by mounting fees and fines. Many plants currently discharging to coastal waters are being threatened with closure. Vapor compression systems, as furnished by Maloney Process Inc. (MPI) Engineering, is recommended and specified for SunDragon zero liquid discharge systems. MPI units discharge the 300,000TDS concentrate at the highest temperature, which ideally suits Sundragon’s requirements. Every 1 million US gallons of sea water contains approximately 291,900 pounds of salt-like materials. Zero liquid discharge translates to 145 tons of dried salt to dispose of as solid waste. At fifteen cent cost per cue of electricity, Vapco vapor compression produces distilled water at .006 cents per gallon. If your electric cost is seven and one half cents per kWh, the cost per gallon of distilled water is .003 cents per gallon. The cost of brine disposal without zero liquid discharge may be higher than the cost of the purified water. For example, the Vapco system rejects 120,000 gallons of 210F brine per million gallons of treated seawater, based on 35,000 ppm. The hotter the reject brine, the more efficient the salt or constituent recovery. SunDragons utilize solar power or waste heat for the recovery of dissolved solids. Hot brine allows the SunDragon evaporation to proceed in a more cost efficient manner. A SunDragon requires a reject brine with a minimum 300,000TDS for cost efficient Zero Liquid Discharge. Solids recovered are disposed of as solid waste or may be of additional value. A major advantage of a SunDragon is Zero Liquid Discharge producing solid waste for disposal, needs no discharge permitting, monitoring, compliance cost and time. The resulting near-dry salt bulk density is about 40 lbs/ cu.ft. That represents about 7,300 cu. ft. of salt/million gallons for disposal, or about the volume of 54,700 US gallons of water.

 

SunDragon Solar Salt Factory's No Salt Brine Solar salt and mineral recovery system. zero discharge waste brine Solution Mining Potash   salt, potash, trona, and magnesium salts SunDragon use a versatile, practically nontoxic heat transfer fluid thermally stable at temperatures up to 315°C (600°F). The technology is simple and easy to install and requires much less space than evaporation ponds. Evaporation ponds require months to reduce water to the desired levels for processing of the minerals to be recovered, SunDragon takes hours to accomplish the water reduction desired, however water is recovered for reuse.   Avoid permitting problems, discharge restrictions, fines and surcharges! SunDragon salt factories now have a brine heater for a 24 hour solution to the discharge brine problems of desalination and water purification. We have combined solar and conventional heat sources(gas or electric) for continuous operation salt and mineral recovery. Our salt makers rely on state of the art vapor compression units, evaporation in one pass, for the hot reject brine that makes our salt makers work more efficiently, manufactured by Maloney Process Inc. of California . Maloney Process Inc. of California also manufactures our brine heaters for 24 hour operation for the recovery of salts and minerals. Brine heaters are used after sundown and in conjunction with sun up drying for solid waste disposal or value added processing. Our state of the art vapor compression units and brine heaters handle a broad spectrum of constituents. A system for a zero discharge waste water treatment system. Once the testing program is complete allow 4-6 weeks for delivery For more information E-mail: sundragonsaltfactory@yahoo.com Phone 561 271 8131 find out how.     SunDragon Salt Factory's as a concentrator for lithium bearing mineral brine Process for solar staged concentration of lithium chloride brine salt and mineral recovery system.   LITHIUM SOURCES Actual and potential sources of lithium are from continental brines, geothermal brines and oil field brines. Lithium brines exist in the Paradox Basin, Utah. The recovery of these lithium brines can be accomplished without pounding using vats for precipitation. SunDragon Hybrid Salt Factory's are a brine concentrator which makes this system possible. Lithium Bearing waste Brine the Smackover Formation (Jurassic) in south-central Arkansas.

Minerals such as calcium, silica, and magnesium hydrogen sulfide and iron will send most manufactures of RO and VC to the drawing board for a new quotation. There is no stable pricing in the industry Problem 2, discharge of liquid brine: A liquid concentrate of greater tds than the influent that has been desalinated or purified has to be disposed of.   SunDragon Salt Factories No Problem 1, broad spectrum of constituents: 100% Green No chemical pre treatment required, broad spectrum of constituents acceptable. No Problem 2, discharge of liquid brine: No liquid brine: solids only.   Municipal Wastewater Treatment RO systems and the discharge stream disposal: the difficulties in managing the large amounts of concentrate produced     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 The cleanest water and the greenest discharge solution!   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     For more information E-mail: sundragonsaltfactory@yahoo.com Phone 561 271 8131
