Chlorination involves adding chlorine (Cl2), sodium hypochlorite (NaOCl), or calcium hypochlorite (Ca(OCl)2) to water. When chlorine is introduced, it undergoes hydrolysis to form hypochlorous acid (HOCl) and hydrochloric acid (HCl) in water. Hypochlorous acid is the active disinfecting agent responsible for killing bacteria, viruses, and other microorganisms
In addition to disinfectants, various chemicals are used to treat suspended solids and turbidity in water. Coagulants, such as aluminum sulfate (alum) and ferric chloride, are added to facilitate the coagulation process, where small particles clump together to form larger aggregates known as flocs. These flocs can then be easily removed, resulting in clearer water. Flocculation agents can further assist in this process, enhancing the removal of impurities.
Another challenge is navigating the complex global regulatory environment. API wholesalers must be well-versed in the regulations of various countries to facilitate international trade while ensuring compliance. This can be particularly challenging given the recent shifts in trade policies and tariffs, which may affect the cost and availability of APIs.
