Major water shortages are being faced throughout the world in both developed and developing countries. Desalination offers a reliable and sustainable source of water that is not climate dependent. As a result many utilities throughout the world are turning to desalination to improve the security of their water supplies and to avoid major social and economic disruption.

For more than 15 years, TTTGlobal has been delivering sustainable water solutions across the globe, covering every element of the water cycle. TTTGlobal engineers, scientists and planners are committed to providing sustainable, cost-effective and innovative water solutions that meet our clients’ water needs now and into the future.

Scope of Services
TTTGlobal has experience in both small and large-scale desalination projects covering the full life cycle of services including:

  • Feasibility studies, including site selection
  • Pilot testing
  • Detailed design
  • Contract administration
  • Construction phase services
  • Commissioning
  • Testing
  • Operational optimization and troubleshooting

    TTTGlobal Skills
    To be successful, desalination projects require a multidisciplinary approach. TTT Global is able to offer a multidisciplinary team to work with clients from conception to completion. Skills available include but are not limited to:

  • Water quality assessment
  • Intake and outfall marine infrastructure including hydrodynamic modelling to determine the fate of plumes, and prevention of recirculation
  • Technology selection and design
  • Site selection and investigations for suitability
  • Materials selection and durability assessment to meet design life
  • Environmental studies including impact assessment/ statements and monitoring
  • Community consultation
  • Electrical and water supply connecting infrastructure
  • Probable capital and operating cost estimates and procurement/contracting strategies
  • Owner’s engineering services

    Membranes Technologies
    Aqua Membranes is exploring two varieties of open channel spacers. Embossed membranes are more appropriate for low-pressure applications, including under-the-counter household RO systems and ultra-pure water in electronics and pharmaceutical production, since high pressure can cause the membrane dimples to collapse.

    World’s water reserves are consisted from 97.5 % from oceans and 2,5 % from rivers and lakes ! So, future is in seawater!

  • During the last decade, the number of desalination plants has been increased significantly and exceeded 10 Thousand plants in the world.
  • During the last decade, cost of producing drinking water from seawater , has been decreased from 4 US$/m3 to 1 US$/m3.
  • Desalination plants can be realized through Built-Operate-Transfer (BOT) method , with no burden to public institutions.

    Management Projection for 25 Years

  • First investment cost is around US$ 160 Million (Finance cost is not included )
  • Plant has 6 months feasibility period and 18 months project period. Turnkey delivery is 24 months . Backpayment is within 10 years ,first 2 years nonpayment.
  • Plant will cover its investment costs within 9 years. Estimated operating period is about 25 years .

    From Saltwater to Tap Water
    How does desalination plants convert saltwater to drinkable fresh water?

    1. 1. Pumping Seawater: Millions of gallons of seawater a day comes in through intake pipes. Protective screens minimize sucking in sea life and large debris.
    2. 2. Pretreatment: Water is filtered for sediments, bacteria and viruses. Solid waste is sent to a landfill.
    3. 3. Desalination: Seawater is pumped through concentric filters. More than 99% of the salt and minerals is removed.
    4. 4. Wastewater: Brine, the remaining water from desalination, is saltier than seawater, so it is mixed with industrial wastewater or other seawater to reduce salinity before it is returned to the sea.
    5. 5. Post-treatment: Water is chlorinated. Minerals can be added to match taste of existing water.
    6. 6. Storing and delivering water: Fresh water is stored and released into the municipal water system.
