Over the years, because of fast growth of population and industrial activities, we have increasingly polluted ou waters. Conventional water treatment processes become indequate with the identification of new contaminants in the water. To overcome these challenges, a particular emphasis is accorded to the implementation of environmentally, eco-friendly and less-energy technologies for water treatment processes. In this context, we investigate wether new chemical treatments employing organic polymers are efficient enough to provide green solutions for waste water recycling. We focus our attention on stabilized colloidal suspensions that show no sedimentation rate. In order to destabilize these colloids, two mechanisms are mainly involved: coagulation and floculation. These mechanisms depend on the aggregation rate between particles modelised by the Smoluchowski's coagulation equation. In this paper, we study the number concentration of coagulated particles and we show more the time step decreases, more the error on moments of order 0 decreases for a certain number of particles.
