Building a Sustainable, Affordable Desalination Model For a Greener Future in the US
Learn MoreBy late 2024, an unprecedented drought affected nearly every U.S. state, impacting over **150 million people** and **318 million acres of crops**. This crisis, intensified by saltwater intrusion in rivers like the Delaware, threatens the drinking water for nearly 14 million people and makes desalination a critical solution.
The seawater desalination membrane market is projected to exceed **$5 billion by 2028**, driven by increasing water scarcity. While Reverse Osmosis (RO) holds the largest market share due to its established technology and high efficiency, energy consumption and the environmental disposal of brine remain significant concerns.
The high energy consumption of traditional desalination methods is a major roadblock. Energy requirements for reverse osmosis vary with feedwater salinity—higher salinity levels demand more pumping power. The global average SEC for desalination by RO is **5.5 kWh/m³**.
Our technology provides comprehensive solutions to the industry's biggest problems, from high energy intensity to the environmental impact of brine disposal.
Achieve up to a **30% reduction** in Specific Energy Consumption (SEC) and Transform Brine into Valuable Resources.
The WEGen RED technology is a proprietary renewable energy device that addresses energy consumption and carbon emissions head-on. It leverages Reverse Electrodialysis (R.E.D) to turn saltwater into clean energy.
Our process reduces the energy consumption from a baseline of **3.5 kWh/m³** to an average of **2.45 kWh/m³**.
Our system eliminates liquid waste, ensuring full brine treatment for resource recovery.
Our process offsets **3.1 kg of CO₂** for every tonne of brine water processed, supporting a sustainable, circular economy.
The WEGen technology seamlessly integrates with existing Reverse Osmosis systems for easy adoption and scale.
Desalination plants discharge **142 million tons of brine daily**, harming marine ecosystems. Meanwhile, there is a high demand for magnesium, of which **85%** of the world's supply comes from China, posing significant supply chain risks. MediSun's technology solves both problems.
Magnesium is a critical mineral for industries like aluminum, steel, and pharmaceuticals, but its supply is highly concentrated.
By recovering critical minerals from waste streams, our **WEGen Green** technology transforms high-concentration brine and CO₂ into valuable magnesium compounds. This process not only eliminates toxic waste but also offers a sustainable pathway to decarbonization and resource recovery.
For every cubic meter of brine processed, MediSun extracts **8-15 kg of MgCO₃**, turning waste into a valuable resource.
WEGen Green transforms brine from a desalination plant into a resource, extracting magnesium and capturing CO₂, redefining Carbon Capture, Utilization, and Storage (CCUS) with sustainable innovation.
Our pilot project in Gwang Yang, Korea demonstrates the effectiveness of our process with impressive performance metrics, showcasing its viability for large-scale applications.
Nothing goes to waste. MediSun's integrated system turns salty wastewater (brine) into clean water, electricity, and valuable minerals—all from one process. The salinity of the final discharge is returned to normal seawater levels without the need for additional mixing.
