Particles in water, such as clay, usually have a negative charge. Se hela listan på differencebetween.info 2017-12-10 · Coagulation is a chemical process and flocculation is a physical process, In coagulation, the process involves the utilization of a coagulant that has the ability to destabilize the charged particles which are not settleable whilst flocculation involves a similar destabilization process that is achieved through physical mixing and by adding organic polymers. Flocculation is synonymous with agglomeration and coagulation / coalescence. Basically, coagulation is a process of addition of coagulant to destabilize a stabilized charged particle.

Flocculation vs coagulation

Coagulation, Flocculation, Sedimentation, and Filtration A large portion of particles suspended in water can be sufficiently small that their removal by sedimentation or filtration is not practicable. Most of these small particles are negatively charged, which is the major cause of the stability of suspended soil particles. COAGULATION, FLOCCULATION AND CLARIFICATION OF DRINKING WATER By Terry L. Engelhardt, Application Development Manager, Drinking Water Photo by author The intent of this paper is to provide cursory information about coagulation, flocculation and clarification. This knowledge will provide a basis for understanding the needs of the Coagulation and Flocculation 1.

When flocculation is in progress the mixing The equipment allows for the well-known 'jar tests' to be conducted on water samples requiring treatment to determine the correct coagulant dosage. A laboratory investigation of the treatment potential of a coagulation process in the context of stormwater treatment was undertaken.

This enables their removal by sedi-mentation, dissolved air flotation or filtration. Colloidal Coagulation and flocculation are often used in combination. In some cases, the use of a coagulant or flocculant is sufficient to form settleable and floating floccules. The aim of coagulation is to destabilise a colloidal solution, so that polluting matter can bunch together to form floccules.
