In tertiary treatment, which is the final step, the aim is to further purify the treated wastewater, often making it suitable for discharge into natural water bodies or even for reuse. Ultra-filtration membranes and advanced oxidation processes often utilize oxidizing agents like chlorine or ozone to eliminate pathogens and organic pollutants. Furthermore, processes such as reverse osmosis may require the addition of specialty chemicals to ensure optimal membrane performance and prevent fouling.


In the case of finished pharmaceutical products, stability testing encompasses not just the API but also the entire formulation, including excipients, which are the inactive substances used to formulate the drug. The interactions between the API and excipients can affect the overall stability of the product. For example, moisture-sensitive APIs may require specific excipients that can provide a protective barrier against moisture uptake.

In recent years, issues surrounding the safety and environmental impact of water purifying chemicals have come to the forefront. Chlorine, while effective, can form harmful disinfection byproducts when it reacts with organic matter in water. This has led to increased interest in alternative methods of disinfection that minimize these risks. Additionally, the use of biodegradable flocculants and coagulants is being pursued to reduce environmental impact.
