Cyanobacteria are freshwater microorganisms that can bloom and produce toxins that contaminate water. There is thus a need for methods to remove cyanobacteria, by flocculation for instance. Here, we prepared new flocculants by modifying waterwork sewage sludge. Flocculant (A) or (B) were prepared by treating 3 g of preprocessed sludge in hydrochloric acid and heating at 200 or 250 °C for 3.0 h. Flocculant (A) and (B) were used to remove Microcystis aeruginosa colonies by adding 0.75 mL of flocculant to 100 mL of algal culture and incubating fo...
