Coagulation and Flocculation in Water and -


Daniel Valtakari Dissertation & Presentation - SlideShare

With coagulation, destabilized particles begin to collide and create small masses, often called “pin flocs” or “micro flocs”, since they are barely visible to the naked eye at around 50 μm in size. Coagulation, Flocculation, and Sedimentation Subject Area(s) Environmental Systems, Chemistry Associated Unit Drinking Water Treatment Process Lesson Title Drinking Water Treatment: Coagulation, Flocculation, and Sedimentation Header Grade Level 10 (9-12) Lesson # 2 of 3 Lesson Dependency Lessons: 1. Deflocculation is an antonym of flocculation. As nouns the difference between deflocculation and flocculation is that deflocculation is the dispersion of an aggregate to form a stable colloid; the reverse of coagulation or flocculation while flocculation is a condition in which clays, polymers or other small charged particles become attached and form a fragile structure, a floc.

Coagulation means to curdle; it basically refers to a chemical process in which the destabilization of non-settleable particles takes place. These particles form clumps with the help of a coagulant. On the other hand, flocculation means to form flocs. Coagulation & Flocculation in Wastewater Treatment ¾For alum and iron salts −T is typically 15 to 30 min −G is typically 20 to 75/sec −GT is typically 10,000 to 100,000 ¾For lime −T is typically 1 to 2 min in rapid-mixing basins −T is typically 5 to 10 min in flocculation basins −G is typically ≥100/sec Staged coagulation-flocculation can enhance CEPT performance. For example, at primary clarifier overflow rates of over 6 m/h (3,600 gpd/ft2) during peak flow treatment, TSS and BOD removals of 80 to 95%, and 58 to 68% were achieved, respectively, using 60 mg/l ferric chloride, followed by 15 mg/l polyaluminum chloride, followed by 0.5 mg/l anionic polymer. Coagulation is a process to neutralize charges and then to form a gelatinous mass to trap (or bridge) particles thus forming a mass large enough to settle or be trapped in the filter. Flocculation is gentle stirring or agitation to encourage the particles thus formed to agglomerate into masses large enough to settle or be filtered from solution.

Coagulation is process carried out by using coagulating agents like alum which coagulates the impurities present in raw water treatment. Flocculation is a  The process of precipitation/coagulation/flocculation transforms dissolved contaminants into insoluble solids, assisting in the contaminant's subsequent removal  Mar 1, 2018 Flocculation is the chemical process of adding substances, known as flocculants, to cause the colloidal substances in the water to stick together,  Coagulation & Flocculation.
