Why can polyaluminum chloride treat sewage do you know? Polyaluminum chloride manufacturers for your confusion, the role of polyaluminum chloride is through it or its hydrolyzed products of the compression of double electrical layer, electrical neutralization, coil net and adsorption bridge and other four aspects of the role completed.
The particulate matter that can be oxidized by oxidants to cause COD is precipitated and filtered out, thus reducing COD and particulate matter precipitation, and undoubtedly reducing SS. The so-called BOD refers to the oxygen amount required for organic matter in water to be decomposed by aerobic microorganisms, which reflects the amount of organic matter that can be biodegraded in water under aerobic conditions.
If these organics are removed by precipitation, the BOD is reduced. While polyacrylamide is a high-resolution flocculant, organic polymer flocculant has a large surface adsorption effect resulting from the formation of larger flocs between particles.
Any water treatment method has limitations, that is, not necessarily using flocculants and coagulants can reduce the indicators of the water, if all the organic materials in the water dissolve, do not become colloidal, and do not exist in the form of particles, adding flocculants and coagulants will have little effect.
