The market assessment of this innovation has been self-declared by the provider and has not been independently verified. For more details, please contact the innovator directly.
Floating hexagonal modules of 0.3 m2 are placed in the water reservoir one by one. Once modules are joined each other up to cover all the water surface, water losses due to direct evaporation are reduced, and the penetration of sunlight and photosynthesis (and hence algae growth) are prevented. Modules adapt well to water level changes by staying in the irrigation reservoir slopes. Overall, the system is able to bear wind speeds up to 90 km/h and have a minimum lifespan of 10 years.
Limitations/conditions under which this innovation does not work or is less effective
A loss of performance may be expected at wind speeds higher than 90 km/h (maximum physical load), or for periods of use greater than 10 years (although expected lifespan of the polymer is 15 years).
Added value
Modular units are lighter than other existing floating modular covers, and their implementation in reservoirs is easier than other floating membranes and shade covers. Maximum effectiveness has been achieved combining an optimal design with an advanced polymers transformation process. These advantages make the manufacturing of modules cheaper and more economically feasible than other current solutions. Modules adapt to any reservoir geometry -already built or under construction-. No additional engineering modifications in reservoirs are required.
