  • Techno-economic feasibility study of providing variable frequency drive for high pressure pump, SWRO plant at NDDP, Kalpakkam

    The cost of product water is a key factor in determination of acceptability of any desalination system and plant. In case of Sea Water Reverse Osmosis plants, most of the energy consumed is in the form of electricity. The High Pressure Pump (HPP) is the single major energy consuming equipment with a share of above 75%. Hence reduction in energy consumed by HPP will have a substantial effect on ...

  • Improvement in motor performance during high-pressure pump starting at NDDP, Kalpakkam

    The major energy requirement required for a seawater reverse osmosis plant is in the form of electrical energy. The primary energy requirement in the process is the electrical energy fed to high-pressure pumps to pressurise the feed seawater to the membranes. This high-pressure pump, being a high inertia load, requires very high torque at the time of starting. This requirement results in ...

  • Seawater Desalination

    Seawater covers 71% of the planet surface and represents 97% of the world's water,and seawater has a lot of resources to be explored.Along with recycled wastewater, it is one of the few rainfall-independent water sources.However,in the current condition,seawater cannot be used directly because of the high salinity.To solve it,many methods of desalination are adopted. ...

  • High performance boron removal from seawater by two-pass SWRO system with different membranes

    Boron in the desalinated water produced by the seawater reverse osmosis (SWRO) system is one of the most challenging issues for drinking or irrigation water uses. In recent years, many post-treatment methods and designs for boron elimination have emerged and attracted lots of attention, but only a few cases have demonstrated high performance and economic efficiency. The main aim of this work was ...

  • Cleaning biofouled membranes early improves plant operation. Comparison of autopsy and cleaning results on a small BWRO and large SWRO

    Abstract It is a fact that all new reverse osmosis membranes start to foul as soon as they start operation. The only variable is the rate at which they foul. Most RO plants operate at a differential pressure (ΔP) of 1.5 - 3 bar. Cleaning usually occurs when the ΔP is 10-15% above the design specification. This paper explores the benefits of early identification of foulants ...

  • Seawater reverse osmosis system for supplying potable water for airport in saudi arabia

    The Background Saudi Arabia General Authority of Civil Aviation (GACA) is responsible for constructing, managing, operating, and maintaining airports and air navigation infrastructure in Saudi Arabia. The city lacked adequate water production and distribution systems around the airport. GACA’s objective was to increase water production to meet projected growth in demand, and ...

  • Overview of seawater desalination status and challenges

    Introduction World oceans contain over 97.2% of the planet’s water resources. Because of the high salinity of ocean water and the significant costs associated with seawater desalination most of the global water supply has traditionally come from fresh water sources – groundwater aquifers, rivers and lakes. Today, however, changing climate patterns combined with population ...
