제목 Flocculation optimization of Spirogyra Using Polyaluminium Chloride
초록 Flocculation is known to be one of the most effective ways to harvest microalgae. This study aims to reduce the amount of flocculant and optimize Flocculation conditions to maximize the yield of algal biomass. To achieve this goal, the Response Surface Methodology (RSM) was used to optimize the concentration of coagulant concentration, reaction pH and cell density for harvesting. Response Surface Methodology (RSM) was used to optimize concentrations of flocculant, reaction pH and cell density. Microalgae and Spirogyra varians were flocculated using polyaluminium chloride as an inorganic flocculant. According to the RSM results, the optimal flocculation conditions were calculated with an optical cell density of 0.33 at 5 ppm aluminum chloride, pH 7.5 and OD640. The obtained recovery yield of S.varians was 97.6% at the optimal condition.
