Coagulation and flocculation occurs in successive steps, allowing particle collision and growth of floc. Suspended particles vary in source, charge, particle size, shape, and density. Flocculation: Physical processes such as mixing is used as a technique in flocculation. Please download PDF version here Difference Between Coagulation and Flocculation in Water Treatment, 1.“Flocculants & Coagulants.” ChemTreat. Coagulation means to curdle; it basically refers to a chemical process in which the destabilization of non-settleable particles takes place. Coagulation and flocculation steps are important aspects in the context of drinking and wastewater treatment since it allows the separation of suspended particles present in water effectively. (14868618507)’ By USEPA Environmental-Protection-Agency . In contrast, in flocculation, the de-stabilization is brought about by physical techniques such as mixing of the solution, and also sometimes by the addition of polymers. Flocculation is synonymous with agglomeration and coagulation / coalescence. 2. 5. Coagulation and flocculation are two main and important steps in drinking and wastewater treatment. Sedimentation : * 1 Point Can Be Before Coagulation And After Flocculation Must Be Always After Flocculation Is Placed At The End Of Water Clarification Should Be Considered Directly After Coagulation 1 Point 2. Groundwater and surface water contain both dissolved and suspended particles. You can download PDF version of this article and use it for offline purposes as per citation note. Coagulation is the neutralization of the electronic charge on suspended particles. Coagulation and flocculation are two processes commonly used in water treatment in order to get rid of unwanted suspended material in water. Meanwhile, flocculation is a mixing technique that promotes agglomeration and assists in the settling of particles. Flocculation, in physical chemistry, separation of solid particles from a liquid to form loose aggregations or soft flakes. Coagulation and flocculation process in water treatment. Figure 02: Drinking Water Purification Process. Compare the Difference Between Similar Terms. Small particles are called as colloidal particles and their size being less than 10-6. After coagulation the destabilized particles can collide, aggregate so flocs can be formed. During the flocculation procedure, the solution which is coagulated already is mixed gently. Flocculation is synonymous with agglomeration and coagulation / coalescence. Once the coagulants are added and the charges of the particles are neutralized, it allows the particles to interact with each other and stick together. What is Flocculation in Water Treatment The floc is subsequently removed in most cases by sedimentation. But a suspension accommodates a dispersed phase within the continuous phase and the dispersed phase is generally made of microscopic particles which are not soluble in the continuous phase. These particles form clumps with the help of a coagulant. For water treatment, coagulation is generally followed by flocculation. 1. As nouns the difference between aggregation and flocculation is that aggregation is the act of collecting together (aggregating) while flocculation is a condition in which clays, polymers or other small charged particles become attached and … 1 CE 370 Coagulation and Flocculation Part 2 Rapid Mixing and Flocculation ¾Rapid mixing is used to: −Disperse chemicals uniformly throughout the mixing basin −Allow adequate contact between the coagulant and particles −Microflocs are produced ¾Flocculation is … A solution is made when a solute dissolves itself completely in a solvent and becomes one continuous phase. These flocculates are easily disrupted, being held together only by a force analogous to the surface tension of a liquid. Coagulation and flocculation are an essential part of drinking water treatment as well as wastewater treatment. This allows the bridging and strengthening the floc which increases the weight of floc while also increasing the rate of settling. Coagulation and flocculation occurs in successive steps, allowing particle collision and growth of floc. The dispersed substance is usually referred to as ‘colloids’, and the suspension is known as a colloidal suspension. Difference Between Coagulation and Flocculation in Water Treatment www.differencebetween.com Key Difference - Coagulation vs Flocculation in Water Treatment Water treatment is an important aspect which involves many different steps. Flocculation: The process of agglomeration of the destabilized particles to such a size that separation by sedimentation and filtration is possible. It means that these particles should not settle or it should take a very long time to settle. Coagulation and flocculation provide the water treat-ment process by which finely divided suspended and colloidal matter in the water is made to agglomerate and form flocs. The coagulant reacts with the particles or colloids in the suspension and imbalances its chemical charge. If coagulation is incomplete, flocculation step will be unsuccessful, and if flocculation is incomplete, sedimentation will be unsuccessful… It requires the presence of both physical and chemical processes.
