Coagulation, Flocculation, & Sedimentation. Sedimentation 1 Sedimentation . Coagulation Chemical treatment typically is applied prior to sedimentation and filtration to enhance the ability of a treatment process to remove particles. Two steps typically are employed: coagulation and flocculation. CBC, HEMOGLOBIN A1C, SEDIMENTATION RATE, RETICULOCYTE COUNT, HIV VIRAL LOAD, VITAMIN B3, ABO GROUP & RH TYPE. Coagulation is a process to neutralize charges and then to Many water treatment plants use a combination of coagulation, sedimentation, filtration and disinfection to provide clean, safe drinking water to the public. ... BLUE. 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. & flocc. Coagulation and flocculation • Removal of colloids • The individual colloids must aggregate and grow in size • Coag. Coagulation and Flocculation The Figure 8.4 shows the interparticulate forces acting on a colloidal particle. The repulsive forces are due to the electrostatic ZP The attractive forces are due to van der Waals forces acting between the particles. 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. •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. Coagulant: Chemical that is added to destablise the colloidal particles in water or wastewater so that floc formation can result. Phlebotomy is comprised of 170 staff members spread out over 37 sites. 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. If coagulation is incomplete, flocculation step will be unsuccessful, and if flocculation is incomplete, sedimentation will be unsuccessful. Suspended material may be particles, such as clay or silts, originally present in the source water. M4 & Introduction 3. Sedimentation, or clarification, is the processes of letting suspended material settle by gravity. Beyond this point the net resultant force is repulsive. COAGULATION Coagulation and flocculation occurs in successive steps, allowing particle collision and growth of floc. Some of these steps are sometimes combined in … Trace the pathophysiology of Hemophilia and identify clinical manifestations and risk factors of the said disease; and 5. Discuss the etiology, anatomy and physiology of the blood and the coagulation cascade; 4. 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 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 4. 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: Coagulation, Flocculation and Sedimentation Dr. John T. O’Connor, PE . Suspended material or floc is typically created from materials in the water and chemicals used in PT, PTT, FACTOR II ACTIVITY, FIBRINOGEN, D-DIMER FOR COAGULATION DETERMINATIONS.
