The coagulation and flocculation is the process used for waste water treatment by using chemicals. However, this is done before the sedimentation process as it improves the ability to remove contaminates from the water. In addition, the coagulant chemical holding the electrical charge which is positive adds up and disables the electrical charges which are negative on the particles. However, the forces are disrupted that possesses the collision separately. Likewise, the chemicals of the flocculation are majorly having two types such as anionic as well as cationic. The chemicals of the coagulation having three major types such as organic coagulants, inorganic coagulants, and combination of both of them. In addition to this, the global coagulants and flocculants market has been witnessing a significant transition from conventionally used chemical flocculants including ferric chloride as well as alum, towards natural products that are derived from plants. On the other hand, demand for natural flocculants and coagulants gas spiked in the recent years and it is expected to remain this trend during the prediction period.

Moreover, Asia Pacific market known for the highest revenue-generated region for coagulants and flocculants solution and it is predicted to record the maximum growth over the stated period. Coagulants and flocculants are mostly developed to facilitate the partition of suspended particles existed in a solution. However, these particles are extremely tiny, and the steadiness of such suspended particles is an outcome of their charge and the size between them. Furthermore, treating a solution to eliminate suspended particles requires chemical flocculation and coagulation on the basis of the nature of colloids present in the solution. Thus, the chemicals for flocculation and coagulation processes are significant in effluent water treatments such as sludge thickening, lime softening, solid removal, solid dewatering, as well as water clarification. Flocculants work by collecting the huge number of destabilized particles together and causing them to drop out of the water solution. However, some of the majorly used flocculants for water treatment are come colloidal clays like bentonite, activated silica, and some metallic hydroxides with a composite structure such as ferric hydroxide, alum, and others.

Thus, the process of flocculation and coagulation is very cost-effective and simple. It effectively separates many types of particles from the water solution. Increase in demand from end-use industries such as power generation, municipal water treatment, chemical processing, mine water treatment, and others is a crucial factors driving the expansion of the global coagulants and flocculants market. However, the substantial amount of investment in water infrastructure over regional level in emerging countries including India, China, Indonesia, Vietnam, and other strives to enhance availability of pure and hygienic drinking water sanitation as well as supplies facilities. The vital municipal water treatments are membrane treatments, desalination, water processing, and sewage treatment. Vietnam region is known to have the huge natural reserves of several energy resources including mining, coal, oil, natural gas, and water for hydropower generation. Coal is one of the major resource for power generation. Consumption of coagulants and flocculants has increased significantly in the Vietnam region.
