This method can concentrate freshwater microalgae −1 Superabsorbent polymers Chlorella sp. at a relatively high biomass concentration of 90.23 g L . Without further dewatering, the con- Swelling kinetic centrated microalgae can be directly used to produce biofuels by oil extraction or fermentation. The kinetic Ionic strength characteristics of PSAPs swelling in diﬀerent solutions were investigated. The results indicate that the negative PSAPs recycling inﬂuence on absorbency caused by ionic strength was greater than microalgae concentration. Compared with the diﬀusion part, water absorbed by the relaxation of PSAPs was dominant and accounted for over 97%. Equilibrium
