This can be used for boiler makeup, NOxcontrol, cooling tower makeup and process use. The remaining five percent is a slurry concentrate that may be sent to a smallsolar pond, reduced to dry solids in a crystallizer or spray dryer, or used for ash wetting.Brine Concentrators Can Recycle:• Cooling tower blowdown• Oil and gas fieldproduced water• Demineralizer waste• Reverse osmosis reject• Electrodialysis reject• FGD wastewaters• Boiler blowdown• Softener waste• Plant drains• Salty effluents• Mine drainage• Landfill leachateBenefits: • Corrosion resistant titanium—High grade constructionmaterials mean GE brine concentrators will last for decadesand provide reliable operation. • Scale control—Proprietary seeded slurry technology controlsscale, often limiting cleanings to only once per year. • Patented brine distributors—Individual tube distributors ensure a smooth flow of brine, avoiding scale formation.• Variable waste flows—GE’s largest single brine concentratortreats 1,200 gpm, while small units treat as little as 10 gpm.• Energy-efficient operation—In the vapor compressionconfiguration, the brine concentrator uses 21 to 37 BTU per pound of waste feed. This converts to 50 to 90 kWh per1,000 gallons of feed, which is 25 to 50 times more efficientthan conventional single-effect, steam-driven evaporators• Ability to run on electricity or steam—Typical operation is by mechanical vapor compression, but brine concentratorsmay also run on steam in a multiple-effect configuration.• Fully automated operation—Maintain precise system controlwhile minimizing operator interactionCrystallizerMeeting stringent zero-liquid-discharge requirements also requires a crystallizer, to reduce brine concentrate to a dry solid.Recovered water can be recycled back to plant processes, while an easy-to-handle dry solid can be safely disposed of in anapproved landfill.• Ease of use—With simple color graphic controls and anautomatic wash system, GE’s crystallizers are easy to operate.• Ease of installation—Skid-mounted, fully packaged systemswith all auxiliary equipment and controls.• Valuable product recovery—Systems can be designed torecover specific salts from a waste stream.• Expertise in zero liquid discharge—GE has more than 35 years of experience developing and implementing thermaltechnologies to solve zero liquid discharge challenges forcustomers worldwide.Complying with stringent wastewater treatment regulations and reducing water usage are critical considerations in industrytoday. Numerous environmental regulations, rigorous permittingprocesses, and lack of water availability, among other factors, are driving many industrial facilities to implement zero liquiddischarge (ZLD) systems as a solution.GE’s ZLD systems eliminate liquid waste streams from your plantand produce high purity water for reuse. In many cases, yourplant’s water consumption can be reduced by up to 90 percent—saving money and helping to protect the environment. You mayeven be able to capture valuable by-products and sell them tooffset your costs.With more than 35 years of experience in the design, delivery,commissioning and service of ZLD systems, GE provides acomprehensive portfolio of technologies for ZLD applications,including brine concentrators, evaporators, and crystallizers.Proven performers andhighly reliable, GE ZLDsystems offer 95%availability and are up to 30 percent more energyefficient than conventionaldesigns. These technologiescan often be combined with other GE equipment,such as ultrafiltration (UF),reverse osmosis (RO),electrodeionization (EDI)and ion exchange to provide the optimal solution. Our specialistscan tailor a system to fit your wastewater characteristics, flowrates, and end-product requirements.As the pioneer of thermal ZLD systems, GE is continually developingnew thermal solutions that respond to changing market needs. Ourextensive global experience can help you tackle the challenges ofstringent discharge regulations, process optimization and effectivewater and wastewater management. GE ZLD systems can helpsimplify the permitting process, thereby accelerating your plantdevelopment schedule and alleviating environmental concerns.Our strong vendor relationships enable strategic sourcingagreements and, in turn, offer you the most competitive pricingavailable. With multiple contracting methods, a variety of systemoptions, and highly experienced design and delivery teams, GE can custom-design a system for your maximum benefit.Robust Solutions for Demanding ApplicationsGE’s large installed base of robust systems is proven to performacross a broad range of applications, including: • Power • Synthetic fuels• Primary metals processing • Microelectronics• Chemical• Pulp and paper• Coal mining• Battery manufacturing• PVC manufacturing• Uranium mining• Petroleum and petrochemical• Oil refining• SAGD heavy oil recovery• Cogeneration• Fertilizer• Solid waste (leachate and secondary sewage effluent)• Coal liquefaction• Ethanol productionCompressorVentDistillateWastewaterHeat ExchangerDeaeratorBrineDistributorsWasteBrineRecirculationPumpDistillatePumpVapor CompressorSteamCondensateHeatingElementWasteRecirculationPumpFeedFlash VesselMist EliminatorShenhua Coal Liquefaction Project, Inner Mongolia, 590 gpm, 2009Huntington Power Station, Huntington, UT, 200 gpm, 1974 Indiantown Generating Plant, Indiantown, FL, 580 gpm, 1995Gila River Power Station, Gila Bend, AZ, 2,400 gpm, 2003PEMEX Cadereyta Refinery, Monterrey,Mexico, 116 gpm, 1998Experience, Reliability, Results Achieving ZLD: Equipment Overview
