The secondary treatment stage is primarily biological, relying on microorganisms to break down organic matter. However, several chemicals are still employed to enhance this process. For instance, flocculants like polyacrylamide may be used to promote the settling of biomass, facilitating easier removal of residual sludge. Additionally, nutrient management is critical during secondary treatment, as excess nitrogen and phosphorus can lead to water bodies’ eutrophication. To address this, chemicals such as ammonium sulfate or magnesium hydroxide may be introduced to balance nutrient levels and avoid environmental imbalances.
