Water is essential for life, but not all water sources are similar. For companies, industries, and municipalities that utilize water desalination and water treatment, it is critical to understand that seawater and brackish water have a big difference between them. Despite both having salt, their salinity levels, sources and treatment methods are different.
At ADVANCEES we specialize in seawater and brackish water treatment solutions, offering advanced reverse osmosis (RO) systems to purify and desalinate water for industrial, agricultural and municipal use. Let’s first break down some differences between seawater and brackish water. Then we’ll begin discussing some of the newer and most effective seawater and brackish water treatment options.
Seawater vs Brackish Water: What’s the Difference
1. Salinity Levels
- Seawater: Seawater contains a high salt level, approximately 35,000 parts per million (ppm) of dissolved salt. It’s found in seas and oceans and must go through high-pressure desalination in order to effectively remove salt and minerals.
- Brackish Water: Brackish water contains a lesser salinity level, between 1,000 and 15,000 ppm. It is a mixture of freshwater and seawater, and can be found in estuaries, coastal aquifers, and some inland bodies of water.
2. Sources
- Seawater: Comes from oceans and is abundant but requires extensive treatment for potable and industrial use due to high salinity and contaminants.
- Brackish Water: Found in estuaries, rivers meeting the ocean, underground aquifers, and inland lakes with high salt concentration.
3. Treatment Complexity
- Seawater Treatment: Due to high salinity seawater requires seawater reverse osmosis (SWRO) systems with high pressure pumps and specialized membranes.
- Brackish Water Treatment: Brackish water is less salty than seawater but still requires brackish water reverse osmosis (BWRO) systems with lower pressure and energy.
4. Industrial and Commercial Applications
- Seawater Desalination Uses:
- Coastal cities with freshwater shortages
- Large-scale municipal water supplies
- Industrial applications such as processing of oil & gas
- Agriculture in arid coastal areas
- Brackish Water Treatment Uses:
- Inland water treatment for drinking and irrigation
- Industrial water supply for factories
- Power plants and mining operations
- Groundwater desalination for rural communities

Conclusion
Understanding the difference between seawater and brackish water is essential when choosing the right desalination system. Whether you need seawater desalination (SWRO) or brackish water filtration (BWRO), ADVANCEES provides cutting-edge solutions to meet your water purification needs.
The global demand for sustainable water solutions has never been greater, particularly in areas where freshwater is scarce, and brackish water is the primary resource. Traditional methods of water treatment are effective but very energy-intensive, thus expensive to operate.
Enter solar reverse osmosis systems, a game-changing solution that actually uses the energy from the sun to make brackish water clean. Solar-powered systems ensure energy efficiency with higher steps in reverse osmosis technology, setting the scene for water treatment in the times to come.
What is Solar RO?
Solar reverse osmosis (RO) is a water purification process that uses solar energy to power high-pressure pumps, which force water through semi-permeable membranes. This filtration process removes dissolved salts, minerals, and impurities, producing clean water suitable for drinking, irrigation, and industrial applications. Solar RO systems provide a significantly economic and environment-friendly alternative as compared to the traditional methods of desalination in the case of brackish water treatment.
Application of Solar RO Systems in Brackish Water Treatment
Brackish water, though much more abundant with salinity between freshwater and seawater, is seldom utilized because of the complexities in its purification. Solar reverse osmosis systems are designed to meet such challenges; ADVANCEES offers different solutions for different clients: two standouts being
SSWRO: Solar Seawater Reverse Osmosis System
The SSWRO system is designed to treat seawater and high-salinity brackish water sources. Available in capacities ranging from 15,000 to 66,000 GPD, these systems are well-equipped to handle extreme environmental conditions. Fully automatic controls make the SSWRO units require very minimal operator intervention and are thus ideal for deployment in remote or coastal areas where a reliable freshwater source is vital.
SBWRO: Solar Brackish Water Reverse Osmosis System
The SBWRO system is a brackish water treatment scheme with reduced energy consumption compared to other seawater desalination systems. Capable of supplying between 4,000 to 26,000 GPD, the SBWRO units are an energy-efficient solution for inland areas with limited access to freshwater. It is thus ideal for meeting water demands in areas with scarce freshwater supplies, providing clean, potable water through sustainable solar energy.
Why Solar RO is the Future of Brackish Water Treatment
1. Renewable and Sustainable Energy Source
Traditional RO systems depend on electricity or diesel generators, both of which are expensive and environmentally taxing. Solar reverse osmosis systems harness the power of the sun, reducing reliance on fossil fuels and lowering carbon emissions. This makes them an eco-friendly solution for treating brackish water in areas where sustainability is a priority.
2. Cost-Effective Water Treatment
Solar RO systems significantly reduce operational costs by utilizing free solar energy. In regions with high sunlight availability, industries and communities can achieve long-term savings on energy bills, making these systems a financially viable option for water treatment.
3. Adaptability for Remote Locations
Brackish water is almost always found in remote or off-grid areas where traditional water treatment infrastructures are not available. Solar-powered RO systems, an example of which is ADVANCEES’ SBWRO, are portable and easy to install with a minimum of maintenance. Their adaptability will ensure access to clean water even in the most challenging environments.
4. Scalable Solutions for Diverse Needs
Solar reverse osmosis systems can be scaled up for the water needs of small communities, large municipalities, and industrial facilities. Advancees offers modular and customized solutions that cater to various capacities, ranging from small-scale installations to large-scale operations.
5. Technological Advances and Durability
The solar-powered RO systems from ADVANCEES are equipped with an inbuilt energy recovery device and high-performance membranes to boost efficiency. These solar-powered plants will provide reliable performance and a long lifetime even under very adverse environmental conditions.
Brackish Water Solar Reverse Osmosis Process
The process of purification in solar reverse osmosis systems is divided into three major stages:
- Pre-treatment: Large particles, sediments, and organic matter are removed from the brackish water through the first step of filtration. This stage protects the RO membranes from fouling and scaling.
- Reverse Omosis Filtration: High-pressure solar-powered pumps force the water through semi-permeable membranes. Membranes catch salts, minerals, and other impurities and let the cleaned water through. Then, the concentrated brine is safely discharged.
- Post-treatment: Water is stabilized by correcting pH and disinfection to make it qualitatively suitable for drinking, irrigation, or industrial purposes.
Applications of Solar RO Systems for Brackish Water
- Agriculture: It supports irrigation in arid areas through the use of purified water, increasing yields and saving fresh water.
- Industries: Provides high-quality water for manufacturing at a lower operating cost, which will help to meet the target for sustainability.

COMMERCIAL
This project was built to deliver treated water for an irrigation system in a farm
The RO unit Includes the appropriate high-pressure pump, FRP pressure vessels, spiral wound thin film composite RO membranes, Sch 80 PVC low pressure feed piping, and high-pressure piping or hose.
This RO system is skid mounted assembled, hydro-tested and functionally tested before leaving our factory.
The RO system supplied includes PLC based controls and is capable of automatic operation with minimal operator intervention. Safety devices are provided to protect the RO system and its components from common fault conditions.
Level controls, located in the owner’s permeate storage tank, will send a control
signal to the RO system control panel to begin the start sequence.
At the start signal the feed valve will open and membrane flush valves will open. At the end of the pre-flush cycle the membrane flush valve will close.
As water pressure builds in the RO high pressure feed pump suction line, a pressure switch senses the line pressure of the water entering the pump. This switch activates a timer which delays further start sequences until all water lines and pressure vessels reach normal start-up pressures. At the end of the time delay, a start control signal is sent to the RO high pressure feed pump starter.
The RO high pressure feed pump then starts and supplies the necessary feed water
pressure to the membrane array.
The RO feed water is split into two streams, permeate or purified water and concentrate or reject water. The RO permeate flows to the permeate water storage tank. The concentrate is disposed of in accordance with local environmental regulations or method of reuse. When the permeate storage tank is full the level switch sends the shutdown signal to the RO control panel and the system then begins it’s post-flush cycle which removes all concentrated contaminants from the system. Once complete, the system waits for the next start signal.

Is Desalination a Sustainable Solution to Water Scarcity?
The fact that the world is undergoing a water shortage is not news. Honestly, it makes sense. The population in our cities and urban areas continues to grow exponentially. Of course, this puts a considerable strain on the existing water supplies. Of course, the quality and quantity of water are simply becoming inadequate. Desalination may be a solution.
Water Scarcity
Of course, this is a significant issue. Clean and fresh water is essential for survival. Many are searching for solutions to this problem. One which has been frequently raised is the process of desalination of salt water. However, many wonder if desalination is a sustainable solution to water scarcity. Of course, there are desalination pros and cons.
What is Desalination
In order to evaluate this idea, we must understand exactly what desalination is. Quite simply, desalination is the process of removing salt from seawater. Of course, there are different types of desalination. At first glance, this seems like the perfect solution. After all, seawater is plentiful all around the world.
Desalination Pros & Cons
Of course, the response to this solution has been quite varied. While there are a number of positives, there are negatives as well. On the plus side, the process is considered safe. Integrating it into current water systems does not come with significant health risks.
However, the process can be costly, thus it may not be the answer for those countries who struggle economically. The process also has some environmental issues including its reliance on fossil fuel energy. While alternatives (solar and wind power) are being developed, it is not widely available.
Of course, it is necessary to dispose of both the brine produced by desalination and the hazardous contaminants produced by it. Incorrect use of this method results in the death of numerous marine species. Definitely shows problems with desalination wrongly implemented.
Of course, the wrong retrieval of the seawater to be desalinated often kills local marine life – the fish, animals, and organisms simply get swept up during the water collection process. Without a doubt, each of the above-mentioned issues individually would result in questioning the process’s appropriateness. The combination of them all properly addressed makes less leery to desalination. Is desalination good or bad?
Of course, overcoming this issue is extremely difficult, and solutions will most certainly continue to be debated around the world for the foreseeable future. That said, one thing is imminently clear. A problem with regard to the water supply exists and finding answers grows more critical each day.
