PAC adsorption bridging role: adsorption bridging mechanism mainly refers to the adsorption and micelle polymer material with a bridge connected. Can also be understood as the same number of particles of two large middle due to have a different number of particles are connected together. High-molecular flocculant has a linear structure, they have some parts with the micelle surface acting chemical group 30% of PAC, when a high polymer in contact with the particles, groups with specific micelle surface the mutual reaction of adsorption, while the remainder of the polymer molecules are stretched in the solution, the other surface may have vacancy adsorption particles, so that it plays a role of bridging the polymer connection. If small particles, the extended portion of the polymer particles sticking vain second, then sooner or later part of this stretch will be adsorbed particles originally PAC on other parts of the polymer can not play the role of a bridge , while the particles and in a stable state. Polymer flocculant dosing excessive, the particles will produce another stable surface saturation phenomenon. Already bridging flocculation of particles, such as by intense prolonged agitation, cross-linked polymer surface may disengage from the other particles, heavy and roll back to the original surface where the particles PAC prices, resulting in a steady state again . PAC color is yellow or light yellow, ferric chloride as a dark brown or dark red, ferric chloride PAC is based in the actual water treatment applications evolved, which combines aluminum Advantages of ferric coagulation and, aluminum ions and iron ions form has improved significantly, the degree of polymerization is also greatly improved. Easily soluble in water. It has a floc formation block, high adsorption performance, sludge dewatering filter good performance characteristics, especially when dealing with high turbidity water and low turbidity water, the treatment effect is obvious. In fact, PAC and PAFC are two different concepts, PAFC is a new type of inorganic polymer coagulant, the solid product is brown, red-brown powder.
