Coagulation typically occurs in the early stages of water treatment and involves adding coagulants to raw water. The main function of these substances is to destabilize colloidal particles—tiny, suspended particles that resist settling due to their negative electric charges. By introducing coagulants, which are often positively charged, these destabilized particles begin to clump together in a process known as aggregation.


Understanding Water Treatment Chemicals


Quality control is paramount in the production of APIs. Regulatory agencies such as the Food and Drug Administration (FDA) in the United States and the European Medicines Agency (EMA) in the European Union set stringent guidelines to ensure that APIs meet specific standards. These regulations dictate everything from the sourcing of raw materials to the manufacturing processes and final testing methods. Ensuring that APIs are free from impurities and produced in compliance with good manufacturing practices (GMP) is critical for the safety and effectiveness of pharmaceuticals.


In addition to coagulants like alum, flocculants are also widely used in sewage treatment. Polyacrylamide is a common flocculant that enhances the agglomeration of particles, making them easier to remove during the clarification process. By promoting the formation of larger and denser flocs, polyacrylamide can significantly improve the efficiency of solid-liquid separation, reducing the overall volume of sludge generated.
