Effects of Different Types of Coagulants on the Nutritional Quality Tofu Produced in the Northern Part of Nigeria In many cases, two or three types may be used at the same time in a plant. SUBMITTED BY:-ASHISH BANSODE M.E.—WATER RESOURCES ENGINEERING 2. Moringa oleifera, Cicer arietinum, and Dolichos lablab were used as locally available natural coagulants in this study to reduce turbidity of synthetic water. coagulants, such as polyaluminum chloride (PACl, in the case of Al-coagulants) represent a relatively type of coagulation reagents, which were developed in order to increase the efficiency of coagulation-flocculation process. 3. Polyelectrolyte, Koaret PA 3230 was used as the coagulant aid. When added to water, these highly charged ions to neutralize the suspended particles. However, polymers are generally more costly than inorganic coagulants. 95% ethyl alcohol best fixative for cytology; Formalin best fixative for histopathology; Hopwood Classification of Fixatives: 1. Natural coagulants show bright future and are concerned by many researchers because of their abundant source, low price, multifunction and biodegradation. Coagulation process of soymilk containing various coagulants was characterized by viscosity under a shear rate of 2 s −1 at 37 °C. ), tartaric acid (l & 2%) and acetic acid (2%) gave higher total solid recovery than sour whey. College of Food Engineering, Harbin University of Commerce, Harbin, 150076 China. Still, the most common coagulant in the United States, it is often used in conjunction with cationic polymers. COAGULANTS• These are substances which promotecoagulation.• They are indicated in hemorrhagic states.• Fresh whole blood or plasma provide all thefactors needed for coagulation & are the besttherapy.• Also, they act immediately. Coagulants such as alum, ferric sulfate, and cationic polyelectrolytes all work by suppressing the zeta potential of the colloidal system to a value sufficiently low that the colloidal particles will collide and then coalesce under the influence of slow stirring. The three variables … types’ primary coagulants and coagulant aids. … Primary coagulants neutralize the electrical charges of particles into the water which causes the particles to clump together (Schulz and Okun, 1984). Four widely different water supplies were studied in terms of alkalinity, turbidity, and concentration and nature of natural organic matter (NOM). Water … Chemically, coagulants are either metallic salts (such as alum) or polymers. What are anticoagulants used for?
