The final touch: algae culture on urine and RO concentrate for pigment production
ThemeEnergy & Nutrient Factory, Innovation / new techniques
Summary
Ammonium will be recovered from the Reverse Osmosis (RO) concentrate thrugh the algae culture that will use it for its growth. Moreover, the possibility will be tested to use source separated urine as substrate for the algae culture. The aim of this research is to study the growth of the microalgae G. sulphuraria on urine and RO concentrate and thereby recover nutrients. The recovered product is the blue pigment phycocyanin. Phycocyanin is used as fluorescent dye, food additive and colorant, and cosmetics.
