Abstract

This review aims to highlight entropy in the Brownian motion (BM) and coagulation process background. In water treatment processes, pertinent questions relating to entropy, BM, and coagulation are often asked: Since entropy measures disorder of a system, does disorder manifest in polluted water with its stable colloids, microorganisms, molecules and ions? Are BM and molecular agitation favourable to separation processes? Since high salinity (as in seawater) decreases the disorder, would be increasing surface water salinity a convenient water treatment process? This review has found some links between entropy, BM, and coagulation such as: entropy is neither ‘disorder’ nor does it has anything to do with ‘mixed-up things’ like disorderly desks or shuffled cards. This review has also detailed the ordinary physical and chemical events whose spontaneity can be seen to be due to energy dispersing or spreading out. Coagulation/flocculation processes are employed to separate suspended solids from water whenever their natural subsidence rates are too slow to provide effective clarification. Adding salts to simply increase the ionic strength is almost never a practical option and other additives would be used; however, in seawater, where ionic strength is higher due to its proper dissolved salts, coagulation process is easier. Photovoltaically aided distillation process using large basins simulating sea open sky distillation process would be the greenest and healthiest water treatment technology.
