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.
For instance, in the synthesis of an antibiotic, initial chemical reactions may yield one or more intermediates. These intermediates might require further modifications, such as the addition of functional groups or the alteration of molecular structures, to enhance the drug's antibacterial properties. By meticulously managing these intermediates, researchers can streamline the overall drug development process.
