In 2005 it produced ground breaking references in each of the three major desalination technologies: Multiple Effect Distillation, Multistage Flash, and Reverse Osmosis. This is even more impressive when you consider that the references were in three different geographic markets – the Middle East, the USA, and the Caribbean.- Global Water intelligence, 2006First MVC desalination plantFirst MSF desalination plantFirst MSF desalination plant in the Middle EastFirst MED desalination plant First Reverse Osmosis installationFirst SWRO installationAcquisition of Aqua-Chem water technologies division brings all thermal and membrane seawater desalination technologies under one foldRecognized by Global Water Intelligence with Distinction in the Desalination Company of the Year CategoryAquatech unveils designs for a single MED unit of 10 MIGD capacity1954 19591964 20062000 1997198619722008 Today more than ever, sea water is becoming a viable source of water supply for countries around the world. Aquatech is ideally positioned to answer this demand.Already a leading supplier of membrane technologies, we enhanced our commitment to desalination when we acquired the Water Technologies Division of Aqua-Chem in the year 2000. The addition of Aqua-Chem, a pioneer in thermal desalination, allowed us to become one of the few companies in the world to offer clients solutions in both membrane and thermal desalination.Our history in desalination is almost as impressive as our technical capabilities. In the late 1950’s we developed and patented Multi Stage Flash technology (MSF), installing the first large MSF plants in the Middle East in the early 1960’s. We patented the Multiple Effect Distillation (MED) process and built plants in the Middle East and Far East in the 1970's. Membrane technology development followed in the 1980’s. All of this history has made us a company with first class references in MSF, MED, and SWRO on virtually every continent.Today, Aquatech is not merely an expert on a particular desalination technology, but our experience and exposure to all major desalination technologies make us experts on desalination…..Thermal and Membrane Desalination Over 50 Years of Technology Leadership in DesalinationMED is the future of thermal desalination. Aquatech’s MED desalination technology using a spray film™ design has been developed and improved over decades of in-house research and onsite experience of such systems worldwide to provide an environmentally friendly system to meet the global challenges of a reduced carbon footprint.Multiple Effect Distillation (MED)3This 10,000 m /Day MED Installation, is Saudi Arabia’s first industrial BOOT project3This 10,000 m /Day MED Installation, is Saudi Arabia’s first industrial BOOT project3• Production capacity up to 10 MIGD (45,500 m /day) in a single unit• Significantly lower electrical consumption when compared to other desalination processes• Design flexibility to use low to medium pressure supply steam • Minimum down time and therefore a higher plant availability factor• High purity product water• Operates at a low top brine temperature (<70 °C) to minimize scaling and to prevent corrosion• Allows use of lower cost but reliable and proven metallurgy• Use of Thermo Vapor Compressor to increase efficiencyThe Future of Thermal DesalinationVENTEjectorsAfter-CondenserInter-CondenserThermo-Compressor1st Effect 2nd Effect 3rd EffectMotive SteamSea WaterCondenserDistillateDistillateHeat ExchangerCooling Water OutBrine BlowdownDistillate DistillateDistillateBrineBrine BrineSEAWATERPERMEATEUF FEED PUMPBASKET STRAINER ULTRAFILTRATION UNITSUF BACKWASH PUMPS UF PERMEATE TANK CARTRIDGE FILTERFEED PUMPSSODIUM BISULFITEANTISCALANTCATTRIDGE FILTER UNITSENERGY RECOVERYBOOSTER PUMPHIGH PRESSURE PUMPSEAWATER REVERSE OSMOSIS UNITSREJECTCAUSTICSODIUM HYPO. ACIDAquatech is committed to being the leader in membrane technology with a focus on breaking barriers related to pretreatment, energy recovery, and overall water recovery. We are progressively making strides in optimizing the lifecycle cost and increasing the reliability of SWRO installations. Our approach is to take complete responsibility of SWRO installations to ensure complete design integration….. from intake to outfall, Aquatech can take single point responsibility.Reverse Osmosis (RO)• More than a decade of experience with SWRO desalination installations on four continents• Capability to design and execute integrated desalination projects on an EPC basis • Potabilisation system design for Boron removal as per global standards• In-House programming capabilities lower overall start-up costs, improve reliability and ensure better plant availability• A dedicated Membrane Desalination Center of Excellence focused on the development of cutting edge solutions for large SWRO plantsSWRO Installation on BOOT Basis for King Abdulaziz International Airport, JeddahSWRO Installation on BOOT Basis for King Abdulaziz International Airport, JeddahComplete Solutions from Intake to OutfallAquatech MSF desalination technology was developed more than fifty years ago, and we were amongst the first to install large size MSF plants in Saudi Arabia, a key market for desalination. With our depth of technological expertise and experience in operating plants, we are positioned to offer the best support in design optimization and rehabilitation of existing facilities.•• Highly reliable, and simple to operate and maintain• Simpler supply water pretreatment• Minimum down time; so, higher availability factor• High purity product water• Provides thermal energy efficiency similar to the MED process• Operates at a top brine temperature <110 °C to minimize scaling and to prevent corrosionUses low pressure steam as heat sourceMultistage Flash (MSF) Over 50 Years of Experience36,000 m /Day MSF Installation, Saudi Arabia36,000 m /Day MSF Installation, Saudi ArabiaHigh PressureSteamVentVacuumSystemHeat Recovery StagesBrineHeaterLow PressureSteamHeated Sea Water• •190 -230 FFirstStageHeat Reject StagesSea WaterLast StageDeaerator VentPretreatmentChemicalBrineRecirculationMakeupCoolingWater OutBrineBlowdownDistillateCondensateHYBRID DESALINATION SYSTEM (TYPICAL)MED SYSTEMVENTEjectorsInter-CondenserAfter-CondenserThermo-Compressor MOTIVE STAMSEA WATERCondenser1st Effect 2nd Effect 3rd EffectDISTILLATE DISTILLATE DISTILLATEBRINEBRINEBRINEDistillateHeat ExchangerDISTILLATEProduct Water Blending (if required)BRINE BLOWDOWNTO OUTFALLCOOLING WATER OUT TO OUTFALLPRODUCT WATEREnergy RecoveryLOW TEMPT.

The hybrid desalination approach provides more flexibility and reliability in the supply of fresh water while optimizing plant operation. Further, the Hybrid approach provides flexibility to meet varying consumer demand for power and water in IWPP projects. Hybrid desalination can provide a better answer to the environmental challenges faced by industry by combining the best that thermal and membrane technologies have to offer.Hybrid Configurations• Optimization of life cycle cost for Integrated Water and Power (IWPP) facilities• High level of operational reliability and flexibility due to the presence of both thermal and membrane processes• Flexibility to adjust the final product water TDS by blending higher TDS RO product with very low TDS thermal system product• Higher plant availability factor compared to a standalone RO membrane system.• Utilization of carbon dioxide gas recovered from the thermal system in potabilization.40 MIGD MED in a 4 X 10 MIGD Configuration40 MIGD MED in a 4 X 10 MIGD ConfigurationSWROSWROAquatech’s Resource Recovery portfolio includes recovery of high purity brine or salt crystals from seawater for use in industrial applications.
