Chemical coagulation is a crucial process in water treatment, hence the need for research on its optimization and increasing efficiency. This study explores coagulant/flocculant particle size, mass, and density’s impact on coagulation kinetics. The study employed a computer program that simulates the perikinetic coagulation processes. The simulation’s reliability was confirmed based on the classical Smoluchowski–Müller equations. Destabilization kinetics of the simulated sol revealed linear relation-ships. The coagulation rate adhered to both first-order (R₂ = 0.97) and second-order kinetics (R₂ = 0.98). Coagulant/flocculant particle size, mass, and density significantly influenced coagulation kinetics and efficiency. A tenfold increase in coagulant radius led to a fourfold rate increase.
