Coagulants are chemicals that help in the removal of suspended solids. They work by neutralizing the negative charges on particles suspended in water, causing them to clump together. This process, known as coagulation, is crucial in municipal water treatment plants where reducing turbidity is vital. Common coagulants include aluminum sulfate (alum) and ferric chloride. These materials not only assist in particle removal but also help in the subsequent process of sedimentation, where larger clumps of particles settle at the bottom for easy removal.
2. Synthesis This is the core step where chemical reactions are utilized to create the desired API. The synthesis can be complex, often involving multiple steps and requiring the use of various raw materials and solvents.
