Chitosan (a biopolymer) is an aminopolysaccharide that can be used for the treatment of colored solutions by coagulation-flocculation (as an alternative to more conventional processes such as sorption). Acid Blue 92 (a sulfonic dye) was selected as a model dye for verifying chitosan's ability to treat textile wastewater.

What are the Types of Chemicals used in Wastewater Treatment?

Flocculation of Wastewater Flocculants help to remove very fine particles from the wastewater treatment plant through charge bridging and magnetic neutralization. By adding flocculants, waste particles are encouraged to form into clumps or flocs that can settle out during the sedimentation process.

Quick Answer: What Is Flocculation And Why Is It Important ...

Flocculants, or flocculating agents (also known as flocking agents), are chemicals that promote flocculation by causing colloids and other suspended particles in liquids to aggregate, forming a floc. Flocculants are used in water treatment processes to improve the sedimentation or filterability of small particles.
