If coagulation is incomplete, flocculation step will be unsuccessful, and if flocculation is incomplete, sedimentation will be unsuccessful. This is then followed by sedimentation (see Sedimentation Chapter). The net resultant force is attractive out of the distance x. Coagulation is a process to neutralize charges and then to M4 & Introduction 3. Sedimentation, or clarification, is the processes of letting suspended material settle by gravity. Coagulation Chemical treatment typically is applied prior to sedimentation and filtration to enhance the ability of a treatment process to remove particles. Beyond this point the net resultant force is repulsive. Coagulation Definition Process of destablising colloidal particles (slow settling, non-settling) so that particle growth can occur as a results, smaller particle begin to form larger or heavier floc (agglomeration) which will be removed by sedimentation. Coagulant: Chemical that is added to destablise the colloidal particles in water or wastewater so that floc formation can result. Suspended material or floc is typically created from materials in the water and chemicals used in •The value of pH during coagulation optimal pH-range for Al: 6 - 7.8 Fe3+: 4 - 10 Fe2+: > 8.5 •Temperature •Mixing conditions In practice the coagulation process involves a rapid mixing, flocculation, sedimentation and filtration step. Worldwide, a combination of coagulation, sedimentation and filtration is the most widely applied water treatment technology, and has been used since the early 20th century. CBC, HEMOGLOBIN A1C, SEDIMENTATION RATE, RETICULOCYTE COUNT, HIV VIRAL LOAD, VITAMIN B3, ABO GROUP & RH TYPE. Two steps typically are employed: coagulation and flocculation. Coagulation, Flocculation, & Sedimentation. Trace the pathophysiology of Hemophilia and identify clinical manifestations and risk factors of the said disease; and 5. PT, PTT, FACTOR II ACTIVITY, FIBRINOGEN, D-DIMER FOR COAGULATION DETERMINATIONS. Coagulation, Flocculation and Sedimentation Dr. John T. O’Connor, PE . Sedimentation 1 Sedimentation . Phlebotomy is comprised of 170 staff members spread out over 37 sites. Discuss the etiology, anatomy and physiology of the blood and the coagulation cascade; 4. Coagulation and flocculation occurs in successive steps, allowing particle collision and growth of floc. Sedimentation in water Treatment 4.5 Design tanks 4.5.1 Plain Sedimentation: Example 4.2: Design pre‐sedimentation tanks to be used to remove grit and sand from a river water that is used to produce 20000 m3/d di kidrinking water .Use the overflow rate and Coagulation and Flocculation The Figure 8.4 shows the interparticulate forces acting on a colloidal particle. & flocc. Need for Coagulation and Flocculation • Remove particulate impurities, especially non-settleable solids, and color from water being treated • Coagulation chemicals cause particles to destabilize and clump ... PowerPoint Presentation Author: Suspended material may be particles, such as clay or silts, originally present in the source water. Some of these steps are sometimes combined in … Many water treatment plants use a combination of coagulation, sedimentation, filtration and disinfection to provide clean, safe drinking water to the public. Coagulation and flocculation • Removal of colloids • The individual colloids must aggregate and grow in size • Coag. Identify the medical and nursing management appropriate for the disease.. Hemophilia is an inherited blood clotting disorder, changes in the Factor VIII and IX gene. are used to agglemorate colloids prior to separation of solids • Coagulation: the addition and rapid mixing of coagulant • for destabilization of particles • for initial aggregation of the destabilized particles The repulsive forces are due to the electrostatic ZP The attractive forces are due to van der Waals forces acting between the particles. 4. ...
