Coagulationwith adsorption and charge neutralization mechanism occurs. In this range, the water tends to buffer or stay in the same pH range and will allow the complete mixing of coagulant chemicals. Coagulation can be accomplished through the additional or inorganic salts of aluminum or iron. Effect of coagulation mechanism on membrane permeability in coagulation-assisted microfiltration for spent filter backwash water recycling. D. Ghernaout and B. Ghernaout / Desalination and Water T reatment 44 (2012) 15–28 19 The net repulsive energy would become smaller or even 2) ADSORPTION and CHARGE NEUTRALIZATION Some chemical species capable of being adsorbed at the surfacecolloidal particles Coagulation& Flocculation: Destabilization of Colloids Iftheadsorbedspecies carrya chargeoppositeto thatof colloid reductionof surfacepotential destabilizationof colloidal particle 20 Coagulation is necessary for the removal of the colloidal-sized suspended matter. In situ charge neutralization on governing particle coagulation nucleation and size distribution in macroemulsion polymerization. Water treatment coagulants are comprised of positively charged molecules that, when added to the water and mixed, accomplish this charge neutralization. Sweep flocculation is the primary Once neutralized, particles no longer repel each other and can be brought together. There are four main mechanisms for coagulation: double layer compression, adsorption and charge neutralization, sweep flocculation, and inter-particle bridging. Coagulation is the process of destabilization by charge neutralization. first process in drinking water treatment, coagulation, is to destabilize the particles and allow them the potential to collide and stick together. Coagulation water treatment is the process of destabilization by charge neutralization. Once neutralized, particle no longer repel each other and can be brought together. B. J. Liu a, W. T. Meng b, M. Y. Zhang * a and H. X. Zhang c a Engineering Research Center of Synthetic Resin and Special Fiber, Ministry of Education, Changchun University of Technology, Changchun, 130012, China. Colloids and Surfaces A: Physicochemical and Engineering Aspects 2011 , 378 (1-3) , 72-78. charge with distance from the surface of the particles. Coagulation treatment neutralizes the negative electrical charge on particles, which destabilizes the forces keeping colloids apart. Ghernaout, D. (2020) Charge Neutralization in the Core of Plasma Treatment. Coagulation Mechanisms Double Layer Compression Charge Neutralization from EVEG 3110 at Louisiana State University The high charge neutralization ability remains for samples with B = 1.5 and 2.0, with large proportions of preformed oligomers and polymers. If solubility limit of Al(OH)3is exceeded (typical in water treatment) ... →The principal coagulation mechanism is sweep flocculation with moderate Coagulation is most effective in the pH range of 5-7 because of the waters ability to react with alkalinity.
