The globalization of the pharmaceutical industry has also influenced the API market. Many companies now outsource API production to contract manufacturing organizations (CMOs) located in countries with lower production costs. While this can lead to significant savings, it also raises concerns regarding supply chain integrity and regulatory compliance. Ensuring that these external facilities adhere to rigorous quality standards is crucial for maintaining the safety of the pharmaceutical supply chain.


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.


Given the critical nature of their role, water treatment plants must choose their chemical suppliers carefully. Several key factors should guide this selection process


Descaling with Sulphamic Acid An Effective Solution for Scale Removal


Coagulants, such as alum (aluminum sulfate) and ferric chloride, are also employed in sewage treatment. These chemicals assist in the removal of suspended solids, colloidal particles, and turbidity from wastewater. When added to the treatment process, coagulants promote the aggregation of small particles into larger flocs, which can be more easily removed through sedimentation. This process is particularly important in primary treatment phases, where physical separation of solids occurs.
