Separation Methods in the Algae Technology

Abstract

Carbon dioxide is the air pollutant emitted in the greatest volume nowadays. Capturing and deposition of carbon dioxide require great financial effort. Spontaneous processes exist in nature that can be the basis of re-introducing CO2 into the biological system. A number of valuable products can be obtained including motor propellants. Nowadays petrol companies all over the world invest increasingly more funds into algae technology research, and there are researches going on in the energy, cosmetics, pharmaceutical, and food industry for marketable microalgae components. The viability of the technology is determined by its energy-needs which are mainly affected by the separation of the biomass from the reproduction medium. In this paper, we look into the circumstances as well as the effects of flocculationdensification and ultrafiltration on the algae suspension.
