    Salt Water Desalination: The Ultimate FAQ Guide

    In this guide, you will find all information you’re looking for about saltwater desalination.

    From, basic to advanced concepts – you will learn everything about saltwater desalination.

    So, keep reading to learn more.

    What Is Salt Water Desalination?

    Salt water desalination is the process of eliminating excess salt and other minerals from the water making it drinkable.

    It is also a chemical process that will change saltwater into potable water.

    Desalination entails treating brackish or seawater to create freshwater.

    For this reason, desalination firms employ several technologies from pre-treatment to membranes.

    What Are Some Types Of Salt Water Desalination Technologies?

    There are different saltwater desalination technologies, and others are still under development.

    Besides, there are two main saltwater desalination technologies namely thermal and membrane saltwater desalination.

    Both of these technologies have various subcategories and they all require energy to operate.

    Also, you will use renewable and conventional energy in these technologies.

    • Membrane saltwater desalination technology

    This process uses a permeable membrane that removes salts and other minerals from saltwater.

    Various membrane processes differ in terms of ion size, suspended particles, and molecules.

    Some of these processes include the following:

    Reverse Osmosis And Nanofiltration

    This is a relatively new process in saltwater desalination compared to the other technologies.

    Reverse osmosis applies pressure to drive the feed water via semi-permeable membranes to eliminate salts and other contaminants.

    Nanofiltration will eliminate divalent ions like sulfates, magnesium, and calcium.

    Besides, these processes have operating pressures of between 50 psig and 100 psig.

    Reverse osmosis plants comprise pressure-treatment units, high-pressure pups, membrane and post-treatment systems.

    This technology minimized the rate of corrosion than MED and MSF because of suitable temperature environments.

    However, it will produce 40 to 90 gallons of wastewater if you want to produce 5 gallons of fresh water.

    Illustration Of Reverse Osmosis salt Water Desalination

    Membrane Distillation

    This version applies membrane and thermal technologies that entail membrane-based and distillation desalination.

    Membrane distillation creates a temperature difference between the incoming supply solution on one side and space on the other end.

    The temperature difference causes vapor pressure difference causing vapor to move via membranes to condensation surfaces.

    This process uses hydrophobic membranes that allow vapor to pass through and exclude dissolved substances.

    Membrane filtration functions at low temperatures thus using less heat.

    It will also operate at low-pressure levels than other pressure-dependent processes.

    However, membrane filtration needs more space and the saltwater should be free of organic pollutants, which is a limitation.

    Electrodialysis (ED) Or Electrodialysis Reversal (EDR)

    This is a voltage-driven technology that uses electricity to eliminate salts via membranes to produce fresh water.

    ED operates using direct current where ions move through selective ion membranes to electrodes having an opposite charge.

    Besides, this system will repeatedly reverse the polarity of electrodes.

    Electrodialysis flow chart

    Thermal Salt Water Desalination Technology

    This method is also known as distillation and is one ancient method of desalinating saltwater.

    Besides, you will rarely use this method to desalinate brackish water as it is costly.

    Thermal saltwater desalination entails boiling, evaporating, and then collecting pure water from saltwater.

    Salt remains behind and you will collect the fresh distillate water.

    The subdivisions of thermal saltwater desalination include the following:

    Multistage Flash Distillation (MSF)

    This process entails distilling saltwater via several chambers.

    The successive stages of this process progressively operate at low-pressure levels.

    Here, you will heat feed water under high pressure then pass it via a flash chamber.

    This first flash chamber releases pressure making the water boil quickly causing rapid evaporation or flashing.

    Besides, this process repeats itself in the other successive chambers as the pressure level is low.

    The vapor you collect from flashing passes via heat exchanger tubes where it changes to freshwater after condensation.

    Incoming feed water is cool and will condense vapor in these tubes.

    This process produces about 64% of the global desalinated water besides consuming more energy requiring thermal and mechanical energy.

    Besides, use stainless steel for these plants since they are prone to corrosive effects.

    They also experience impingement and erosion attacks.

    Erosion happens due to turbulence of feed water within the flash chambers where it goes from one chamber to another.

    The benefits of MSF are:

    1. They are easy to construct and operate
    2. No moving components besides conventional pumps and connection tubes
    3. High levels of purification

    The limitations of MSF are:

    1. They are energy intensive requiring both mechanical and thermal energy sources
    2. Adding more stages increase the cost of operation and purchase
    3. High temperatures may cause scaling as salts will precipitate on tunes hence causing clogging

    Multiple Effect Distillation (MED)

     Multiple Effect Distillation

    This process has been in operation since the late 1950s.

    It operates like MSF but the process happens in several series that apply evaporation and condensation at low environmental pressure levels.

    Several evaporators in MED will progressively produce water at low pressures.

    The successive decrease in pressure makes water boil at low-temperature levels.

    Water vapor from the previous vessel acts as the heating medium for the upcoming vessels.

    More vessels mean a high and quality performance ratio and the evaporating water undergoes collection after condensation.

    Some benefits of MED are:

    1. It operates at low-temperature levels hence causing minimal corrosion and scaling
    2. Pretreatment and operation of MED is low since feed water quality is not that important
    3. It consumers less power yet performs better than MSF, meaning it is cost-effective

    Vapor Compression Evaporation Or Distillation (VC)

    This process can occur independently or in collaboration with other processes such as MED.

    The heat you use in this process originates from vapor compression and is not heat originating from steam within the boilers.

    Besides, you will use mechanical and steam jet compressors to condense water to produce suitable heat to evaporate saltwater.

    Mechanical compressors operate through diesel or electricity and are normally used to produce evaporation heat.

    In the evaporator, it will create a vacuum, compress the vapor, and then condense it in tubes.

    In a steam jet, venture orifices form water vapor before extracting it, thereby creating low-temperature atmospheres.

    Steam jets compress water vapor then condense in tube walls to produce condensation heat that will evaporate feed water.

    Besides, they have a small capacity, and have the following benefits:

    1. Low operational temperature minimizes the formation of scales and tube corrosion
    2. It consumes less power as the operating and evaporation temperature is low
    3. The simple method is reliable and suitable for small-scale saltwater desalination

    Solar Desalination

    This method is suitable for small-scale usages as it relies on the sun on to provide energy that evaporates saltwater to form freshwater.

    The vapor that forms will condense on clear glasses or plastic coverings then collects into a trough as condensate.

    Besides, the covering will relay radiant energy and enable the condensation of water vapor on its surface.

    This method is suitable for use in arid areas and the amount it produces varies a lot depending on its design and location.

    Solar Desalination Plant

    Cogeneration

    Here, the source of energy can produce electric power and perform saltwater desalination.

    Besides, you will produce electricity using high-pressure steam that operates the turbines.

    Boilers will produce steam at temperatures of up to 5408°C.

    As steam expands within turbines, its energy and temperature reduce.

    Also, you will use the steam for desalination processes and return the condensate into the boilers for reheating.

    Cogeneration uses less fuel and the energy costs for the desalination process are low.

    However, issues may arise because of permanent coupling between power and desalination plants.

    What Are The Benefits Of Salt Water Desalination?

    More than 300 million people globally depend on saltwater desalination for their daily water needs.

    Saltwater desalination assists in meeting this demand by minimizing the amount of salt in saltwater making it suitable for consumption.

    Also, saltwater desalination is important as freshwater supplies are in limited amounts and not distributed equally.

    Climate change causes extreme floods and droughts and saltwater desalination is a guarantee for clean fresh water at all times.

    Saltwater desalination also adds to the existing freshwater supply in different countries hence ensuring a constant supply of freshwater.

    Besides, it can produce a freshwater reservoir when the demand for freshwater is low.

    Back to the guide ⇪

    What Are The Limitations To Salt Water Desalination?

    Some limitations include the following:

    • The processes consume a lot of energy
    • It can cause aquatic environmental degradation if brine is not properly disposed
    • Health concerns as the desalinated water can harm humans
    • Production of a lot of unusable brine waste
    • It is costly to construct and operate a saltwater desalination plant
    • It may decontaminate groundwater reservoirs
    • The process strips essential minerals out of water

    Limitations To Salt Water Desalination

    What Is Wave-Powered Salt Water Desalination?

    This is a technology that relies on ocean waves to supply power that you will use for desalination.

    It uses free and renewable ocean wave energy making it cost-effective than other processes.

    This system uses wave energy converters to filter the saltwater.

    Besides, this process is still new meaning it can have more potential in the future.

    Back to the guide ⇪

    What Is The Process Behind Salt Water Desalination?

    Performing reverse osmosis to desalinize seal water entails several processes that include the following:

    Intake

    In this stage, you will draw seawater from oceans either directly, through beach wells, or from cooling plants.

    The design of the intake system will minimize marine life loss and fouling.

    Pretreatment

    This is an important stage and care within seawater reverse osmosis systems.

    It entails removing particulate substances that will foul the filtration membranes.

    Pretreatment units can use various methodologies to achieve suitable inorganic and biological reduction.

    Conventional units will apply multimedia filtration as others use special media filtration combining ultrafiltration or disinfection processes.

    Reverse Osmosis

    In this stage, you will separate salts from water and produce concentrated amounts of brine solution.

    Pretreatment ensures the filtration media is clean, thereby allowing clean water to pass through during reverse osmosis.

    Disinfection Or Post Remineralization

    After reverse osmosis, you will realize that the water has no salts and other important minerals beneficial for the human body.

    Also, these minerals will enhance the taste of the water and they include magnesium and calcium.

    Besides, these minerals balance the pH value of water which is more acidic after treatment.

    Organisms like pathogens can thrive in storage tanks that is why it is important to disinfect the system.

    Here, you can use one or a combination of the following:

    1. Chlorine
    2. Ozone
    3. UV light
    4. Chloramine

    Discharge

    After the saltwater desalination process, you remain with a high concentration of brine solution.

    It is important to handle the brine solution carefully as it is harmful to animal and plant life.

    One method of discharging it into oceans is using special outfall discharge brine units.

    Since oceans are large, they are self-regulating but some marine life is sensitive to high levels of salinity.

    For this reason, disperse the bine solution over large areas to maximize the dilution effect.

    What Are The Advantages of Salt Water Machines in Making Drinking Water?

    Technological advancements are making the production process cost-effective.

    The process has low costs than thermal units since they only need electricity and no thermal energy.

    It also ensures a steady supply of clean fresh water.

    Back to the guide ⇪

    What Happens After the Salt is Removed in a Brine Desalination Machine?

    The remaining substance after filtering out clean water has a high concentration of dissolved minerals and other types of contaminants.

    Concentrated management is an important factor when you want to determine a plant’s feasibility.

    Besides, you can dispose of the concentrate via deep good injections on the land or return it to the sea in a controlled manner.

    This is to ensure you do not affect marine life as the substance can have negative effects on the environment.

    If you produce the concentrate inland, you can dispose of it on surface water bodies, wastewater treatment facilities, or evaporation ponds.

    Also, you can mix brine with other water sources to lower salinity levels through diffusers.

    Diffusers will stimulate brine to mix with ocean water and are vital for dispersing brine at several discharge locations from saltwater desalination plants.

    Back to the guide ⇪

    Can Salt Water Desalination Machine Solve The Global Water Problems?

    Saltwater desalination consumes a lot of energy making the process costly and environmentally harmful.

    For instance, the average cost of an acre of desalinated water is up to 4 times as much as that of other water sources.

    Besides, ocean desalination is not efficient since you need at least 2 gallons of saltwater to produce one gallon of fresh water.

    For this reason, saltwater desalination plants cannot solve the water shortage in the world.

    Back to the guide ⇪

    What Is The Energy Consumption Of Salt Water Desalination Machine?

    The energy consumption of saltwater desalination is almost at 3 kWh/m3.

    This includes ancillaries and pre-filters that are equal to the energy transportation companies’ use when transporting water supplies over long distances.

    However, that local fresh supply of water uses an amount equal to or less than 0.2 kWh/m3.

    Besides, the minimum determined amount of saltwater desalination is around 1 kWh/m3, and this excludes pumping and pre-filters.

    Reverse osmosis technology consumes under 2 kWh/m3 allowing less space for more energy reduction.

    Besides, the different saltwater desalination technologies will consume varying levels of energy.

    Back to the guide ⇪

    How Do Small Scale And Large Scale Salt Water Desalination Machine Compare?

    Small-scale saltwater desalination is cheaper to construct and operate than large-scale saltwater desalination.

    Large-scale saltwater desalination is suitable for commercial purposes while the small-scale version is suitable for local purposes.

    Small-scale versions will consume less power than large-scale versions.

    Both of these processes assist in eliminating salt content from saltwater making it suitable for daily human use.

    Also, both of them produce brine as a by-product of the salt water desalination process.

    How Does Reverse Osmosis and Thermal Desalination Compare In Salt Water Desalination?

    Thermal desalination entails applying heat to vaporize saltwater then condensing it in a different chamber to produce fresh water.

    Reverse osmosis entails forcing saltwater through a semi-permeable membrane to eliminate salt and allow clean water to pass through.

    Back to the guide ⇪

    What Are Some Salt Water Desalination Processes That Are Still In Development?

    Some of these processes involve the following:

    Forward Osmosis

    This process uses a semi-permeable membrane to separate salt from water.

    However, it will not use an external pressure system to create the liquid driving force.

    It uses natural gradient pressure that is provided by a more saline draw solution like ammonium carbonate or special magnetic nanoparticles.

    High osmotic pressure makes water move via the membrane and you can separate the freshwater through various means depending on the source.

    How Forward Osmosis Works

    Freeze/Thaw

    This process relies on a phase change to achieve the separation of water and salt.

    The phase change here is from liquid to solid as crystal ice have no salt in their structure thus brine separates from ice.

    Besides, the energy you will use here is a fraction of that needed to change liquid to vapor.

    The challenge with this process is not to melt the ice crystals when washing and separation the crystals.

    Freeze/thaw processes include absorption, indirect freezing, and direct freezing.

    Capacitive Deionization (CDI)

    Carbon aerogels are suitable electrodes because of the following:

    1. Adjustable pore size distribution
    2. High surface area
    3. High electrical conductivity

    As salty water flows via these electrodes, ions get absorbed within the porous structure of the electrodes through the application of low electrical voltage.

    This causes the deionization of saltwater leaving you with clean fresh water.

    Supercritical Desalination (SCD)

    This process produces high pressure and temperature causing a clear distinction between liquid and gas.

    However, they are not suitable for absorbing inorganic salts requiring you to conduct precipitation to remove them.

    This allows you to produce solid waste and purified products.

    Back to the guide ⇪

    What Are The Environmental Impacts of Salt Water Desalination Machines?

    Salt water desalination machine consumes more energy thus it increases reliance on fossil fuels, hasten climate change, and greenhouse gas emissions.

    The water intake is a hazard to marine life as these organisms can get trapped as the system sucks in saltwater from the ocean.

    Brine is a threat to marine life and will lower water quality since it has high levels of minerals and salts.

    Also, since it is dense, it will smother life that is found at the bottom of coastal ecosystems.
