One of the key objectives of chemical dosing in water treatment is to adjust the pH levels of water. Acidic or alkaline water can be corrosive or lead to the leaching of harmful metals from pipes. Common chemicals used for pH adjustment include sodium hydroxide (caustic soda) for raising pH and sulfuric acid for lowering it. Maintaining the proper pH range (typically between 6.5 and 8.5) is crucial for optimal water quality and safety.
The regulatory landscape surrounding APIs is also evolving, with agencies like the FDA and EMA emphasizing the importance of quality and consistency in API production. Recent initiatives aim to streamline the approval process for new APIs while ensuring rigorous safety and efficacy standards. This regulatory support is crucial in bringing innovative therapies to market and ensuring patient safety.
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.
