Flocculent vs Coagulant
混合物不同substan的集合ces, which are physically combined, but do not join chemically. Mixtures show different physical or chemical properties than the individual substances. Solid, gaseous, or liquid substances are mixed in different ratios, in these mixtures. The state of the particles in these mixtures may vary and, depending on that, there are different types of mixtures as solutions, colloids, etc. Coagulation and flocculation are two methods to separate out the suspended particles in a solution. Coagulants and flocculants are formed to assist these processes. Though coagulation and flocculation are used interchangeably, they are two distinct processes.
Coagulant
Colloidal solution is seen as a homogeneous mixture, but it can be heterogeneous as well (e.g. milk, fog). The particles in colloidal solutions are of intermediate size (larger than molecules) compared to particles in solutions and suspensions. However, as the particles are in solutions, they are invisible to the naked eye and cannot be filtered using a filter paper. The particles in a colloid are termed as dispersed material, and the dispersing medium is analogous to the solvent in a solution. The particles are distributed within the colloidal medium, and do not settle down if it is left still. Colloidal solutions are translucent or opaque. Sometimes particles in a colloid can be separated out by centrifugation or coagulation.
凝血是指分散胶体颗粒团聚的过程。悬浮的颗粒的大小通常很小,它们可能在其上或颗粒之间有电荷。通常这些是负电荷,这会导致他们互相排斥。凝结剂用于中和这些电荷。它们通过周围的小颗粒之间的排斥电荷中和。这使颗粒可以团结起来并形成更大的团块。阳离子凝结剂在很大程度上用于此。添加凝结剂后,应迅速混合混合物,以分散整个液体的凝结剂。凝结剂可以是金属盐(例如明矾)或聚合物。聚合物可以是阳离子,阴离子或非离子。
Flocculent
Flocculants are also added to facilitate the settling of suspended particles in a solution. Flocculants facilitate the agglomeration and, therefore, make larger floccules. These tend to settle down due to gravitational force. Flocculants try to bridge the molecules forming clumps. For example, an anionic flocculent will react with a positively charge polymer and will adsorb those particles. This may cause destabilization due to charge neutralization or bridging. In flocculation, flocculants are added slowly and mixed gently. Therefore, small flocs can agglomerate into larger particles.
What is the difference between Flocculent and Coagulant? • Real diamonds are made from carbon, possess a higher refractor index, weigh much heavier compared to fake diamonds and emit a blue glow when subjected to infrared light • Fake diamonds are usually made from silicon carbide or glass, possess a lower refractor index, weigh lesser compared to real diamonds and emit a yellowish glow when subjected under ultra violet light. |
