Evaluation of Fractal Growth Characteristic of Flocs for Aluminium Sulphate and Ferric Chloride Using Microscopy Method

Coagulation and Flocculation processes are some of the important aspects of water treatment. The properties of flocs, such as size, structure, and strength have a significant effect on the solid and liquid separation process also it affects the basic operations of the industrial unit process. Floc structure is an important factor that influencing the coagulation effect and to identify the post-treatment load. The physical characteristics of the floc are therefore fundamental in determining their removal efficiency. Study of floc generated and its growth characteristics in the flocculation process plays an important role as it decides the removal policies, effect on subsequent processes, and ultimately the quality of water. The present investigation is to study the floc growth for two different aluminium and iron-based coagulants, Aluminium Sulphate and Ferric Chloride, respectively, using the microscopy method. This paper deals with the examination of two different kinds of flocs for strength, breakage, recovery, and floc growth rate.
