Abstract Energy consumption from non-renewable fuels is increasing, so there a need for new energy source microalgae. The microalgae Chlorella vulgaris has high lipid content ranging 2-77% of the dry weight biomass, but it small size, 2-10 micrometers, which makes uneconomical at harvesting stage. One cheaper, effective, and environmentally-friendly methods bioflocculation. bioflocculation was ...

In the phosphate industry, thickening process is vital to increasing solid slurry concentration and recovering water that as clear possible. The performance of depends mainly on coagulation–flocculation effect. based flocculant agents concentrate particles: flotation washing plant rejects large flocs, which accelerate their sedimentation velocity. industry worldwide uses synthetical flocculants...
