Abstract: This review discusses the Brownian motion and coagulation/flocculation (C/F) in water/wastewater treatment. In water/wastewater treatment processes, pertinent questions relating to Brownian motion and C/F are often asked. Some of these questions are: Brownian motion and molecular agitation are favourable or not to separation processes? As high sali... Show More

This article belongs to the Special Issue Cleaner and Sustainable Production

Abstract: This review concerns the using of Zeta and streaming potentials in the coagulation process control. Coagulation process is usually explained by charge neutralization mechanism. The negative charge may be quantified by Zeta potential or streaming potential measures. Prior to the advent of streaming current monitors, Zeta meters were the primary inst... Show More
