flocculation water treatment

  • Flocculation

    Flocculation and sedimentation are widely employed in the purification of drinking water as well as in sewage treatment, storm water treatment and treatment of industrial wastewater streams. Typical treatment processes consist of grates, coagulation, flocculation, sedimentation, granular filtration and disinfection.
