Primary coagulants neutralize the electrical charges of particles into the water which causes the particles to clump together (Schulz and Okun, 1984). The list below lists the most commonly used blood collection tubes, their additives and uses in laboratory: 1. The following table describes the types along with examples: Based on the nature of the interaction between the dispersion medium and the dispersed phase, colloids can be classified into lyophilic and lyophobic. Water treatment coagulants are comprised of positively charged molecules that, when added to the water and mixed, accomplish this charge neutralization. ¾Types of Coagulants • Primary coagulants: neutralize the electrical charges of particles in the water which causes the particles to clump together. Therefore, chemical coagulants are often added to overcome the repulsive forces of the particles. In the present investigation, assessment of three different natural coagulants namely seeds of Moringa Oleifera, Arachis Hypogaea (Peanut), Zea mays (Corn)has been carried out. Polymeric coagulants are sometimes added in low dosages (< 10 ppm) to remove particles down to 0.5 μm particle size as compared to 10 μm without the coagulant upstream of a cartridge filter. Manufacturers can produce a wide range of polymers that meet a variety of source-water conditions by controlling the amount and type of charge and the polymers molecular weight. See our Privacy Policy and User Agreement for details. The commonly used metal coagulants fall into two general categories: those based on aluminum and those based on iron.
