A mechanistic mathematical model was developed to predict the performance of cationic polymers for flocculating salt water cultivated microalgae. The model was validated on experiments carried out with Neochloris oleoabundans and three different commercial flocculants (Zetag 7557®, Synthofloc 5080H® and SNF H536®). For a wide range of biomass concentrations (0.49-1.37 g L(-1)) and flocculant dosages (0-150 mg L(-1)) the model simulations predicted well the optimal flocculant-to-biomass ratio between 43 and 109 mgflocculant/gbiomass. At optimum conditions biomass recoveries varied between 88% and 99%. The cost of the usage of commercial available flocculants is estimated to range between 0.15$/kgbiomass and 0.49$/kgbiomass.
开发了一个机理数学模型来预测阳离子聚合物对盐水养殖微藻的絮凝性能。该模型在使用油丰富新绿藻和三种不同商业絮凝剂（Zetag 7557®、Synthofloc 5080H®和SNF H536®）进行的实验中得到了验证。对于广泛的生物质浓度（0.49 - 1.37 g L(-1)）和絮凝剂剂量（0 - 150 mg L(-1)），模型模拟很好地预测了43至109 mg絮凝剂/g生物质之间的最佳絮凝剂与生物质比例。在最佳条件下，生物质回收率在88%至99%之间变化。商业可用絮凝剂的使用成本估计在0.15美元/千克生物质至0.49美元/千克生物质之间。
