Current Challenges in the Desalination Industry
The desalination industry faces significant hurdles related to environmental impact, energy consumption, and high operational costs.
Brine Discharge
Appx. Daily
200M Tons
Brine disposal harms marine ecosystems, with approximately 200 million tons of highly saline water discharged daily, which disrupts aquatic life.
Carbon Emissions
Appx. Daily
50M Tons
Desalination often relies on fossil fuels, leading to a higher carbon footprint, with an estimated 50 million tons of CO2 emitted daily.
High Energy Consumption
Appx. Daily
57GW ~ 110GW
Desalination consumes 3-4 kWh per m³, making it extremely energy-intensive. Energy costs can account for up to 50% of total operational expenses.
Expensive Operations
Per $m^{3}$
$0.50 ~ $3.00
Desalinated water costs between $0.50 and $3.00 per m³ due to high energy and maintenance costs, which limits its widespread accessibility.
Why Net-Zero Desalination is Necessary
The need for net-zero desalination is driven by multiple factors, from growing global water demand to the severe environmental impacts of current methods.
Water Insecurity
Global water demand is projected to rise by 30% by 2050.
High Carbon Footprint
Desalination emits up to 76 million tons of CO2 annually.
Brine Discharge
Over 50 billion cubic meters of brine waste are discharged yearly.
High Energy Consumption
Desalination uses 10-15x more energy than conventional water treatment.
Global Policies & Regulations
Strict regulations are being implemented to protect the environment.
MediSun Pioneers Net-Zero Desalination
We have it all: our comprehensive solution integrates three key pillars to create a complete circular economy.
Water Recovery
Through efficient, low-cost sustainable desalination technology (FO, RED, S-EDM).
Energy Generation
Through net zero 24/7 sustainable power solutions (RED).
Resource Recovery
Through CCU for efficient mineral extraction from brine (Green, S-EDM).
Reverse Electrodialysis - WEGen RED Technology
Our proprietary **Salinity Gradient Power (SGP)** technology generates electricity from saltwater. This unique process creates energy from the difference in salt concentration between two fluids, such as when a river flows into the sea.
- 30% Energy Savings: Reduces specific energy consumption (SEC) by 30% in R/O Seawater Desalination plants.
- Zero Brine Discharge: Eliminates liquid waste, ensuring full brine treatment.
- Net-Zero Carbon Emission: Offsets 3.1kg of CO2 per tonne of brine water processed.
- Retrofit Compatibility: Seamlessly integrates with existing RO systems for easy adoption.
Turning Waste into Value: Recycling Brine for a Circular Economy
Brine is the new "Liquid Gold." It contains valuable mineral resources and energy that are typically discarded.
By recovering critical minerals from waste streams, our **WEGen Green** technology transforms high-concentration brine and $CO_2$ into valuable magnesium compounds.
Key Metrics
- For every $m^3$ of brine processed, MediSun extracts 8-15 kg of MgCO₃.
- The process captures 3-7 kg of $CO_2$ from 1 ton of brine.
This process supports a circular economy and offers a sustainable pathway to decarbonization.

MediSun's WEGen Technology: Complete Circular Economy
Our process ensures nothing goes to waste, turning salty wastewater into clean water, electricity, and valuable minerals.
The integrated system works in a four-step cycle:
- The system reduces the energy used for the RO pumps.
- Electricity generated from the RED technology is supplied back to the RO system.
- The process neutralizes $CO_2$ and extracts magnesium from brine in the CCUS process.
- Neutralized brine is discharged directly into the sea without dilution, with a salinity level similar to normal seawater.
