Zeta Potential of Clay for Wastewater Treatment

Using the SZ-100 Nanoparticle Analyzer, the concentration of additive needed to reduce the zeta potential of wastewater suspended solids to zero can be reliably evaluated and so the efficiency of different additives can be readily compared such that the most economical option can be chosen. Particulate aggregation is typically achieved through the use of additives: coagulants (inorganic) and flocculants (polymeric). In this note, the effect of coagulant choice and concentration on the treatment of suspended clays is analyzed.
