Concept of a technological system for microalgae biomass production with the use of effluents from fermentation tanks

摘要

The presented technology is aimed on the one hand at purifying the effluents from fermented sludge to the quality enabling their discharge to a river, and on the other hand at ensuring the production of high concentrations of algae biomass. The produced algae biomass will be used as a substrate in the process of methane fermentation. The main factor which minimizes the possibility of introducing crude effluents into photobioreactors is a high content of organic compounds and the suspension. The removal of these contaminants from wastewater will proceed with both physical methods via floatation and biological methods with the use of a biofilm. It is expected that biogenes will be effectively removed from effluents through the growing biomass of microalgae.
