Chlorination of waste streams is considered effective for odor control primarily because chlorine oxidizes many chemical compounds present in the water. This oxidation process breaks down odor-causing substances, such as sulfides and organic matter that contribute to foul smells in wastewater. By converting these compounds into less odorous or non-odorous substances, chlorination effectively diminishes the overall odor emanating from the waste streams.

While masking odors with a strong scent might briefly alleviate the situation, it does not address the root cause of the odors, making it a less effective long-term solution. Chlorine's reactivity is crucial in this context; it is not non-reactive, as oxidation relies on its reactive nature to break down unwanted compounds. Additionally, while chlorine can influence pH levels, its primary role in odor control is through oxidation rather than chemical neutralization of pH.
