Abstract
The invention relates to a biofilm based panel that is developed for reducing evaporation in dam reservoirs, and allows biomass production. The biofilm based panel of the invention comprises in general three main layers, a support layer (4), a nutrient layer (2) and a biofilm layer (1). Based on the climate in which the dams are located, a heat storage intermediate layer (3) may also be added. The support layer (4) is the top layer. The developed panel is positioned such that it partially covers the water surface.
Claims12
A multilayer panel for dams covering a part of a surface of liquid for reducing evaporation, wherein the multilayer panel comprises:
- a biofilm layer (1) comprising microorganism, cultivated on a surface of the multilayer panel facing the liquid;
- a nutrient layer (2) comprising nutrients for said microorganism, placed on the biofilm layer (1) such that it is positioned adjacent to the biofilm layer (1);
- a support layer (4) placed on the nutrient layer (2);
- and
- at least one floating support (6) carrying said layers in connection with the support layer (4), preventing these layers from contacting with the liquid and enabling the multilayer panel to float on the liquid by contacting the surface of the liquid.
