Scenario: You are a water treatment plant manager responsible for choosing a disinfection method for your facility. You are considering using either chlorine or ozone.
Task:
This exercise requires individual research and analysis, so there is no single "correct" answer. However, a strong answer would include a clear comparison of chlorine and ozone disinfection, addressing factors like: * **Effectiveness:** Both chlorine and ozone are effective disinfectants but differ in their effectiveness against specific microorganisms and their residual effect. * **Cost:** Ozone systems are typically more expensive to install and operate than chlorine systems. * **Environmental Impact:** Chlorine has a higher environmental impact due to the formation of disinfection byproducts (DBPs). Ozone breaks down quickly in water, leaving fewer byproducts. * **Byproducts:** Chlorine produces DBPs, some of which are considered harmful. Ozone produces fewer byproducts, but the formation of bromate is a potential concern. The report should then explain the decision based on the specific needs of the water treatment facility, taking into account factors like water quality, budget constraints, and environmental regulations.
