    Arid, semi-arid, and coastal regions generally have limited freshwater sources. With populations in coastal regions and arid land steadily increasing, the need for alternative freshwater sources has never been greater. Owing to advanced water treatment technology, populations, and industries in coastal and arid regions can now source potable water from seawater.

    Seawater systems have been utilized for many generations but recent advancements have lessened their operational costs and elevated their productivity. This has triggered global adoption of seawater systems like communities, governments, and industries step up efforts to combat freshwater scarcity.

    Figure 1 Seawater system.

    What is a Seawater System?

    A seawater system refers to equipment deployed to convert seawater into high-grade product water for offshore and onshore use. At present, there are several seawater systems utilizing distinct processes to generate varying grades of product water.

    Although the application of seawater treatment goes back to ancient Egyptian and Greek times, contemporary seawater systems are completely different. They are highly resourceful, reliable, and more economical.

    They are flexible and versatile thereby receptive to distinct applications. Primarily, seawater systems exhibit higher TDS levels given the high salinity of seawater.  They gratify simple and complex product water demands such as drinking water and high-grade industrial water.

    Which technologies are Utilized in Seawater Systems?

    The almost infinite availability of seawater (over 97.5% of earth’s water) is the primary reason most water treatment technologies are centered on seawater. The technologies utilized by varied seawater systems exhibit distinct results and demand varying operational costs. Underneath, we briefly expound on the three commonly utilized seawater treatment technologies.

    Distillation.

    distillation process

    Distillation is a separation process that has been in existence for ages. It characteristically mimics the natural rain creation process by utilizing heat to evaporate water. The lower boiling point of water prompts the evaporation of freshwater consequently leaving the salts and other pollutants behind.

    The vapor is then condensed at lower temperatures and pressure to generate fresh product water (distillate). The solution left behind (concentrate) is then treated prior to disposal. Seawater distillation is primarily undertaken using three processes.

    • Vapor compression.
    • Multi-effect distillation (MED).
    • Multi-stage flash distillation (MSF).

    Reverse osmosis.

    For seawater desalination, reverse osmosis is the globally revered solution. Reverse osmosis was initially incepted in the 1970s but it has really taken off in the recent past. It is a membrane filtration process driven by pressure to shrink the TDS concentration of seawater. Typical seawater reverse osmosis systems eliminate up to 99.7% of dissolved salts thereby providing high-quality product water for distinct applications.

    Electrodialysis.

    Electrodialysis is highly thought of by experts and many predict it will be the future of seawater desalination. It is a membrane technology that ion exchange powered by electric currents. Seawater electrodialysis systems have brine and dilute compartments consisting of cation and anion exchange membranes. EDI is preferred because of its high recovery rate and impurity removal scores.

    Figure 3 Seawater electrodialysis process.

    What are the Application Fields of Seawater Systems?

    Presently, there are over 75 million people reliant on over 22,000 seawater desalination systems globally. Although the Middle East and northern Africa are the principal consumers of seawater systems, the global adoption rates keep surging up every year. The application of seawater systems varies from simple domestic projects to sophisticated industrial applications. Here are some of the renowned sectors intelligently utilizing seawater systems.

    • Production of drinking water in households.
    • Food and beverages.
    • Power generation plants.
    • Refineries.

    • Boats and water vessels etc.

    What are the Primary Features of Seawater Systems?

    The unique configuration of seawater demands that seawater systems are uniquely equipped to withstand high salinity levels. First, seawater systems are integrated with pretreatment units fully equipped with chemical dosing systems, pre-filters, and occasionally antiscalants.

    Additionally, they are endowed with extraordinary TDS tolerance levels, often 35,000ppm and occasionally 45,000ppm for seawater from the red sea. Seawater systems are manufactured in distinct designs like modular, containerized, and skid-mounted. They also have varying flow rates ranging from 1.4m3/day to 2,500m3/day.

    What are the Advantages of Using Seawater Systems?

    At times when basic human functions and vital industrial processes risk extinction due to water scarcity, seawater systems have provided a reliable solution. As freshwater sources are increasingly overwhelmed, the value of seawater systems in water-stressed regions becomes clearer. Underneath, we explore the numerous rewards, users of seawater systems are reaping.

    • They are comparatively affordable.
    • They provide high-quality water for personal, industrial, and commercial applications.
    • They eliminate dissolved salts and other objectionable constituents like bacteria and metals.

    Back to the guide ⇪

    Can Seawater Systems Generate Drinking Water?

    It is projected that over 75 million people currently depend on seawater treatment for fresh drinking water. Seawater systems ensure that the drinking water has acceptable levels of salinity and harmful contaminants such as microbes and volatile metals are nullified.

    In cases where reverse osmosis is used to desalinate seawater, the readjustment of mineral concentration may be necessitated. Typically, health organizations recommend 10 mg/L of magnesium and 30 mg/L of calcium.

    Figure 9 Drinking water from seawater systems.

    Back to the guide ⇪

    Which Pretreatment Processes are Used in Seawater Systems?

    Most seawater systems comprise a comprehensive pretreatment unit tasked with conditioning the feed water. Occasionally, seawater harbors volatile contaminants that if untreated can corrode the seawater system. For distillation systems, seawater with hardness minerals may cause scaling hence water softener systems are utilized as pretreatment solutions.

    For reverse osmosis systems, seaweed, debris, and particulates found in seawater can potentially clog the membranes. To avert this, sediment and media filters are incorporated into the pretreatment chamber. Other applicable pretreatment technologies for seawater systems are:

    • Microfiltration and ultrafiltration.
    • Iron filters.
    • Chemical dosing.

    Back to the guide ⇪

    What is the Maximum TDS Level of Seawater Systems?

    The salinity concentration of water, in general, is expressed by its concentration of total dissolved solids (TDS). Compared to other sources of water, seawater is the most saline hence seawater systems need high TDS tolerance levels.

    Customary seawater systems have a maximum TDS level of 45,000ppm, which is a reflection of the average TDS score of seawater. However, there is highly saline seawater such as the Red seawater, which averages TDS rates of 40,000-45,000ppm. For such waters, seawater systems with maximum TDS scores of 50,000ppm are necessitated.
