Carocell solar desalination / purification technology

Carocell Panels - Solar Water Purification

After intensive research and testing, F CUBED developed the world leading low cost and environmentally friendly Carocell solar distillation technology.

The Carocell panels provide clean, drinkable water with no ongoing expense and requiring:

  • No filters
  • No membranes
  • No chemicals
  • No ongoing power source
  • No expertise

Carocell produces safe, high quality potable water from any source including seawater, groundwater and contaminated or polluted water.

The Company has undertaken projects sponsored by the World Bank, UNDP, World Concern, Water Aid, Oxfam, UNICEF, the Red Cross and various other NGO's often in conjunction with government sponsored initiatives.
Solar Water Farms (with Rain Water Harvesting)
Aggregating panels in a series (A Solar Water Farm) has the increased benefit of:
  • Increasing the volume of water produced;
  • Enabling rainwater harvesting to supplement the distilled water produced;
  • Enabling a fully automated solution incorporating a solar pump.
Community Shelters
Similar to a Solar Farm F Cubed has integrated solar panels to form a "Community Shelter" utilising the Carocell panels as the roof of the shelter to provide distilled water, rainwater harvesting and communal shade.
Zero Liquid Discharge (ZLD)
The Carocell panels can be implemented to enable ZLD, which:
  • Reduces significantly contaminated brine water flowing back to the source water (which is an increasingly common problem among other technologies)
  • Provides the opportunity to recover potentially valuable minerals such as fractionalised salts (sodium chloride and magnesium chloride – used for dust suppression in the mining industry) or lithium.

Distillation purifies Contaminated Input Water
No matter what the source (Seawater, Bore Water, Well Water, Surface Water) the Carocell Panels the contaminated water will be treated effectively without the need for filters, membranes or power:
  • Contaminated water is input into the panel at the top of the unit
  • An internal solar element (fabric) controls the flow and spread of the contaminated water inside the panel:
  • This allows time for the heat inside to evaporate the water; and
  • By ensuring the water is spread evenly across the panel provides for maximum efficiency/output.
Condensation/Evaporation (Distillation) = Purified Water
  • Solar energy passes through the transparent  upper sheet;
  • Heat inside the panel will range between 65-90 degree Celsius, causing:
  • The contaminated water to evaporate off the internal fabric (vapour); and
  • The vapour then condenses on the inside of the transparent sheet (distilled water);
By evaporating water – any solids, bacteria and pathogens in the water CAN NOT evaporate therefore the water is purified.
Panel Design Separates Distilled Water from Non-Distilled Water (Brine)
  • Distilled water will run down the upper sheets into a pure water outlet at the bottom of the unit;
  • Brine water will come flow down the fabric and exit via a separate Brine water outlet at the bottom of the panel; and
  • Brine Water can be fed back into the panel for further processing (ultimately leading to ZLD).
