Water Treatment Plant Operations Quiz! Trivia

What do you know about wastewater treatment, and do you think you can pass this quiz? A wastewater treatment plant cleans sewage and water so that they can be put back into the environment. These plants remove solids and pollutants, break down organic matter, and replenish treated water's oxygen content. If you would like to understand more about water treatment plant operations, this is the quiz for you.
