For the production of energy source,we must reckon with the energy balance of the whole process. Densification and processing of microalgae can consume 50% - 70% of the energy that can be extracted from the cells,?therefore the cultivation should use such a little energy as it possible. In closed cultivation systems,?there are three main energy intensive steps: artificial illumination, dissolution of gas compounds and mixing. We have carried out our measurements in our lab-scale screening photobioreactor system for the investigation of the most energy effective program for aeration. We have found the aeration program considerable solution for lower energy consumption in?algae cultivation.展开更多

The CO2 from stack gases of the various flows of manufacturing and the nitrogen from certain technical wastewater are necessary for the plants even as algae. The transaction of CO2 with this object and the utilization stand a good chance by hungarian clime with the teamwork from the technical environment. The technology is a new solution in Hungary which eases utterance of the impurities. As a result of our research we expanded alga polities which utilize the CO2 from refinery’s stack gas and they grow intensively in the continental clime, too. The critical points of the technology are the concentration of the algae suspension and the extraction because of the high investment and operating costs and high operational time. The algae technology in this direction depends on this step. Our aim is to separate the algae mass faster and more economical from the starter solution. The optimization of the separating operations and technologies takes notice of the environmental and economic aspects.展开更多
