New Bio-Flocculatious Effect and Its Examination
Abstract: Algaetechnology is a significant scope of the international research and developmental work because it’s a green technology that reduces the utterance of impurities and works as a renewing energy source. 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.
