Question

Quizplus · Accepted Answer

Primary treatment mainly removes large solids and debris while secondary treatment involves the use of microorganisms to consume organic matter. This leads to a significant reduction in the amount of organic oxygen-demanding wastes in the wastewater. Toxic metals, synthetic organic chemicals, and organic pesticides are not as effectively removed by these treatment processes. Radioactive isotopes are not typically present in municipal wastewater.
