Following coagulation, sedimentation typically occurs. This is where the heavier flocs settle to the bottom of the treatment tank, allowing clearer water to be siphoned off from the top. To further enhance the removal of pathogens and dissolved substances, chlorination is frequently employed. Chlorine is a powerful disinfectant that effectively kills bacteria, viruses, and other microorganisms that may be present in water. However, it is crucial to control the concentration of chlorine, as excessive amounts can lead to the formation of harmful byproducts.
An active ingredient, also known as an active pharmaceutical ingredient (API), is the specific component in a drug that produces the intended pharmacological effect. For instance, in a common pain reliever like ibuprofen, the active ingredient is ibuprofen itself, which functions by inhibiting enzymes involved in inflammation. Without the active ingredient, the drug would have no therapeutic value.
