Sewage water, which includes domestic, industrial, and agricultural waste, typically contains a mix of organic matter, pathogens, nutrients, and various toxic substances. The treatment process is divided into several stages primary, secondary, and tertiary treatment. Each stage employs specific chemicals to achieve the desired purification levels.
After successful preclinical trials, the API enters clinical development, where it is tested in a series of progressively larger phases in human subjects. Each phase is designed to gather more data about the drug's safety and effectiveness. Depending on the results of these studies, the drug may eventually receive approval from regulatory bodies such as the U.S. Food and Drug Administration (FDA) or the European Medicines Agency (EMA), paving the way for commercial production.
