Coagulant is process in which destabilization is achieved by the addition of salts which reduce, neutralize or invert the electrical repulsion between particles
The colloidal particles are normally less than one micron in size and undergo Brownian motion. The energy of this motion is sufficient to prevent the particles from settling under gravity and particles remain suspended for long periods of time. Colloidal suspensions can be stable or unstable.
In the water treatment industry, the terms coagulation and flocculation imply different mechanisms. |
