Mechanisms coagulation Process
the colloids in water have electric charges on their surfaces, or covered with hydrophilic substance , they are dispersed stably due to repulsion of particles and Brownian movement
the process of coagulation is largely divided into surfaces charge neutralization of particles by absorbing to the particle, and to weaken the repulsion of particles by coagulation chemical . Unstabilized, particles by charge neutralization are called floc or coagulants generally used in the wastewater treament are for example into inorganic coagulants for example, ferric chloride
