Article Synopsis
- Citrobacter spp. can produce a unique cationic chitosan-like bioflocculant (BF01314) that significantly enhances the flocculation and dewatering performance of activated sludge, reaching effective results at low dosages.
- Under optimal conditions (pH 2-8, temperature 25-80°C), BF01314 shows notable improvements in sludge characteristics, including a dramatic decrease in capillary suction time and better sludge compactness compared to untreated samples.
- The bioflocculant displays strong flocculation activity (>99%) and follows a pseudo first-order kinetic model during sludge conditioning, with mechanisms like electrostatic charge patching and polymer bridging playing key roles.
The aim of this study was to investigate the use of a newly developed design game called BLOCKS to stimulate awareness of ethical responsibilities amongst engineering students. The design game was played by seventeen teams of chemical engineering students, with each team having to arrange pieces of colored paper to produce two letters each. Before the end of the game, additional constraints were introduced to the teams such that they faced similar ambiguity in the technical facts that the engineers involved in the Challenger disaster had faced prior to the space shuttle launch.
