Secondary Treatment

Following primary treatment, wastewater is often sent to what is known as secondary treatment. In secondary treatment, up to 90 percent of the organic matter in the wastewater can be removed by leveraging naturally occuring biological processes. Although many types of plant layouts exist to biologically treat wastewater, they all rely on a healthy, well-acclimated population of microorganisms that require careful management. Various inputs like dissolved oxygen, temperature, and nutrient levels are all critical to the efficiency of the process. A final step, known as secondary clarification, allows wastewater to settle before it is reintroduced into the environment or sent for further treatment, which is often referred to as tertiary treatment.
