英文摘要	a response surface methodology (rsm) was used to evaluate the effects of ph and microalgal biomass concentration (bc) on alkaline flocculating activity for harvesting one freshwater green algae scenedesmus quadricauda #507 and one marine diatom chaetoceros muelleri #862. the ph value and bc were in range of 9.0-12.0 and 0.20-2.30 g/l, respectively. very high regression coefficient between the variables and the response indicates excellent evaluation of experimental data by second-order regressions. optimum conditions for flocculating activity were estimated as follows: (i) ph 11.6, bc 0.54 g/l for strain #507 and (ii) ph 11.5, bc 0.42 g/l for strain #862. the maximum flocculating activity was around 94.7% and 100%, respectively. furthermore, the addition of synthetic ocean water (sow) to the freshwater #507 culture can increase the flocculating activity from 82.13%-88.79% in low algae concentration (0.52 g/l) and 82.92%-95.60% in high concentration (2.66 g/l).
