DESALINATION & ZLD SYSTEMS POWERED BY SOLAR ENERGY
Solarvap is the most efficient ZLD system in the market, as wastewater is treated with concentration technologies powered by solar energy. Solarvap provides huge environmental and economical benefits in the long term.
SOLARVAP®
Energy saving
Water management
Reuse of resources
Reduction of pollutants
SOLARVAP® is the most sustainable water desalination system as it uses the sun’s energy to provide power to desalination plants, thus avoiding any GHE emissions. SOLARVAP® is also an integrated and modular Zero Liquid Discharge solution, as it produces demineralized water from brines and wastewater.
It’s the first industrial desalination solution, totally performed, using the sun’s energy to treat wastewater and produce water of drinking quality, that’s why SOLARVAP® has become the most efficient ZLD system to date.
SOLARVAP® is the combination of two different technologies:
Sun2Heat® developed by Rioglass Solar: A turn-key solar solution to generate process heat for industrial applications.
Envidest® vacuum evaporators developed by Condorchem Envitech: Customized evaporators to treat hazardous wastewater generated in industrial processes.
SOLARVAP® is an advanced meeting of these two technologies; the most efficient solar thermal collectors and the most advanced evaporation technology.
APPLICATIONS OF SOLARVAP® SOLUTIONS
Sea water and brines desalinization.
Drying/replacement of brine evaporation ponds.
Effluent waste reduction by CSH evaporation.
Valuable compound recovery from waste water minerals, oils….)
Clean water production with R.O. from sea desalinization plants

Enhancing the RO system with a SOLARVAP® integrated system
RO systems can recover 40-45% of sea water containing a TDS of 35,000 mg/l. For each 1,000 liters of clean, desalted water produced, 1,200 liters of waste water is generated (TDS around 63,000 mg/l) and must be disposed of, usually by pumping it out into the sea again. This salty water is denser than sea water and lays on the seabed, disturbing the balance of the environment.
The 1,200 liters of waste water (TDS: 63,000mg/l) can be treated, reducing the final waste to 80 liters of sea salt and additionally produce 1,120 liters of distilled water. The total recovery of drinking water will be around 96,5% and produces 80kg of sea salt (commercial product) to achieve Zero Liquid Discharge.
SOLARVAP® HIGHLIGHTS
14,000m2 CSH using SOLARVAP® system produces more than 40,000m3 of clean drinking water per year.
Replacing evaporation ponds with SOLARVAP® evaporation

SOLARVAP® vs traditional evaporation pond
- Less than 25% of the area of the evaporation pond is enough to achieve the same performance with the SOLARVAP® system.
- Performance will be always better than an evaporation pond, as boundary conditions do not affect the process (high humidity, rain, low wind days…)
- Clean water is recovered after evaporation.
- Independent from water or brine quality, salinity or pH.
- Modular solar and thermal systems, allowing wide scalability.
SOLARVAP® HIGHLIGHTS
1m2 of land using solarvap system evaporates the same amount of wastewater as 4m2 of evaporation pond, and generates 4m3 of clean water per year.
