Abstract

We compared Dunaliella tertiolecta LB999 and Tetraselmis sp. KCTC12236BP harvesting efficiency using cross flow filtration (CFF) method. Filtration membranes with pore size of $0.45{\mu}m$ and $0.2{\mu}m$ were selected to determine the efficiency of membrane for harvesting. Cross flow filtration using Dunaliella tertiolecta LB999 with $0.45{\mu}m$ membrane under transmembrane pressure 0.25 bar was the optimal condition for the laboratory system and the harvesting efficiency was 84.7%.
