pH levels in water can significantly affect its quality and the effectiveness of other treatment chemicals. To optimize the treatment process, pH adjusters such as lime (calcium hydroxide) or sodium hydroxide are used to raise or lower the pH as needed. Maintaining a neutral pH range is critical since extreme pH levels can lead to corrosion of pipes, affect the efficacy of disinfectants, and influence the solubility of various contaminants.


- Kemira A Finnish company specializing in water-intensive industries, Kemira provides a range of water treatment chemicals, including coagulants and flocculants. They emphasize sustainability and aim to optimize water treatment processes while minimizing environmental impact.


Another essential chemical in sewage treatment is alum, or aluminum sulfate. Alum is a coagulant used in the primary treatment phase to facilitate the removal of suspended solids and colloidal particles. By causing these particles to clump together, or coagulate, alum aids in their subsequent removal through sedimentation. This is particularly important in reducing the turbidity of wastewater, thus improving the efficiency of subsequent treatment processes. The addition of alum not only enhances removal rates but also aids in the stabilization of organic matter.

APIs are responsible for the pharmacological activity of a drug. When patients take medication, they are essentially consuming a mixture that includes APIs, as well as excipients, which are inactive substances that serve as carriers for the active ingredient. It is the API that directly affects how the body functions and combats diseases. For example, in a common pain reliever like ibuprofen, ibuprofen itself acts as the API that alleviates pain and reduces inflammation.


4. Nutrient Additives In biological treatment processes, especially in activated sludge systems, the presence of nutrients, primarily nitrogen and phosphorus, is essential for microbial growth. Chemicals such as ammonium sulfate and phosphoric acid are sometimes added to maintain the required nutrient balance in environments where wastewater lacks sufficient levels.
