Secondary wastewater treatment is the second stage in wastewater treatment, following what is known as primary treatment. Secondary treatment takes suspended solids and dissolved organic material, captures the solids, and removes greater than 85% of the biological oxygen demand, also known as BOD. Secondary treatment is a biological process which utilizes bacteria to remove BOD followed by secondary clarification.
