2.5. Jar Test procedures on kaolin clarification
Jar Tests were used to evaluate the flocculating efficiency of the
bio-flocculants in clarification of kaolin slurry and were conducted
with a commercially available Jar Tester (ET 720, Lovibond, Germany)
at room temperature. The kaolin suspension was used as a
representative colloidal material because its surface characteristics
are well-understood and is commonly used to evaluate the characteristics
of newly developed flocculants (Lee et al., 2010; Yang
et al., 2009).
