    What is a Seawater Purification System?

    A seawater purification system is a water treatment plant used to eradicate contaminants present in seawater. Using purification systems, households and industries facing freshwater shortages are able to convert seawater into freshwater. Seawater accounts for over 97% of all earth water thus breakthroughs in generating fresh water from seawater are greatly welcome.

    Seawater harbors lots of dissolved salts and other harmful constituents, which significantly limit its use in natural form. The invention of seawater purification systems has augmented global efforts to turn seawater into fresh potable water for industrial, commercial, and personal use.

    What are the Advantages of Seawater Purification Systems?

    It is clearly evident that seawater purification systems have done the environment and its inhabitants’ great service than harm. Thanks to contemporary purification systems, the number of people exposed to freshwater shortages keeps decreasing. The benefits of seawater purification systems have been far-reaching, cutting across various industries, the agricultural sector, and commercial enterprises. Underneath we sample some of the advantages exhibited by seawater purification plants.

    • They have helped preserve freshwater reservoirs.
    • They have reinforced agriculture by providing safe water for irrigation.
    • They are long-lasting equipment, which permits users to make worthy returns on their investment.
    • They protect humans from contracting water-borne diseases such as cholera and typhoid.

    What Purification Techniques are Utilized in Seawater Purification Systems?

    There are multiple ways to purify seawater for industrial, human, and commercial consumption. Broadly, the purification techniques are categorized as biological, physical, chemical, and electromagnetic radiation processes.  Let us briefly look at the inherent seawater purification mechanisms.

    Thermal Distillation.

    Thermal distillation/desalination of seawater is founded on the evaporation of water. Dissolved solids found in seawater cannot turn into vapor hence only freshwater converts into vapor upon heating. The vapor is subsequently condensed and ultimately collected as fresh potable water. To purify seawater using thermal distillation, you can utilize either of the following processes.

    • Vapor compression.
    • Multi-effect distillation.
    • Multi-stage flash distillation.

    Figure 2 Thermal distillation.

    Reverse Osmosis.

    Reverse osmosis is the most popular seawater purification technology. The integration of high-quality seawater filters and semi-permeable membranes makes certain that both large and small contaminants are ejected from the seawater. Osmotic pressure is a key element in seawater reverse osmosis systems since they rely on pressure to flash out the pollutants and generate freshwater.

    Chemical purification of seawater includes chlorination and flocculation while electromagnetic processes involve the use of ultraviolet light.

    What are the Benefits of Using Reverse Osmosis in Seawater Purification Systems?

    Reverse osmosis is inarguably the predominant seawater treatment technique across the world. Its prominence is strictly a product of its effectiveness, efficiency, and dependability. The use of pre-filters in RO systems protects the equipment by eradicating elements that could potentially clog the membranes or corrode the equipment.

    Additionally, RO seawater purification systems are extremely effective in lowering the salt concentration levels of seawater. Reverse osmosis can eliminate up to 99.4% of dissolved solids and unwanted impurities present in seawater. The invention of energy-saving membranes and energy-recovery devices has essentially made RO systems cost-efficient by lowering operational expenditures.

    Figure 3 Reverse osmosis plant.

    Where are Seawater Purification Systems Used?

    The universal demand for freshwater has never been greater. Industrialization continues to proliferate as the human population increases. Unfortunately, existing freshwater sources only account for 2.5% of the earth’s water. On the contrary, over 70% of the earth’s surface is covered by seawater. This has prompted efforts to derive more freshwater for budding industries, coastal and arid populations.

    Below, we explore the various industries or sectors utilizing seawater purification systems as an alternative freshwater source.

    • Residential complexes.
    • Agricultural irrigation.
    • Food and beverages.
    • Car wash businesses.
    • Boats and ships.
    • Refineries and power plants.

    What are the Basic Features of Seawater Purification Systems?

    The high salinity concentrations of seawater demand that seawater purification systems are specialized to withstand high PH and TDS levels. For this reason, the majority of RO seawater purification systems have a maximum TDS level of 45,000 ppm and high operating pressure of up to 1200 psi.

    Additionally, seawater purification systems are fitted with pre-treatment mechanisms, which essentially eliminate large constituents and treat the high alkalinity of seawater. This helps prevent corrosion of the system and mitigates blockage of the perforated membranes.

    Back to the guide ⇪

    How Do Seawater Purification Systems Function?

    All seawater purification systems have similar objectives but employ different means to achieve the desired end result. Reverse osmosis purification systems operate by utilizing high-pressure pumps to force the seawater through a perforated membrane.  Prior to this, the seawater is first taken through a pre-treatment chamber where pre-filters remove relatively large pollutants. Using chemical dosing, the seawater is also pre-treated to reduce the corrosion effect.

    The semi-permeable membranes, in turn, eject dissolved salts and other smaller constituents thereby generating high-grade freshwater. Evaporative purification processes, on the other hand, operate on the basis of separating contaminants from water through evaporation. The condensed vapor is collected in separate gallons as freshwater while the contaminants are disposed of as distillate.

    Figure 4 Reverse osmosis purification process.
