Heliospectra delivers intelligent controllable LED
lighting solutions, giving growers and researchers almost infinite spectrum possibilities. Making it ideal for when it comes to testing different light recipes for optimized microalgae growth. With optimum light, microalgae can thrive, grow, and in massive proportions eat much of the not so active content in wastewater - a context in were most ordinary plants or macroalgae would have died.
Submersed in a glass tube, the lights are doing their job inside a custom made wastewater treatment photobioreactor. Once a week the nutrient reduction in the wastewater is measured as well as the amount of algae after harvest (susp.). Heliospectra´s highly controllable LED
light raise possibilities to keep the light as a controlled factor in the photobioreactor, making the microalgae grow rapidly, and when refined become a resource such as biofuel/gas.
Transforming wastewater into an algae stew has many advantages. The wastewater could once again be transferred back into the society’s system, tightening the loop of recycling, and help decreasing nutrients leak to our valuable nature, causing overfeeding of our oceans and lakes with the result of algae blooms and stinking beaches.
In addition to Lund Municipality, Heliospectra, and SLU
, the project includes the European Spallation Source (ESS
), Lund University’s Faculty of Engineering (LTH
), as well as such companies as Alfa Laval, AnoxKaldnes, BioMil, Lunds Energi Group and Purac.
