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.

One of the most compelling benefits of PQQ is its powerful antioxidant properties. Antioxidants play a crucial role in neutralizing free radicals, which are unstable molecules that can cause oxidative stress—a contributing factor to numerous chronic diseases, including neurodegenerative disorders, cardiovascular diseases, and even cancer. By providing robust antioxidant support, PQQ helps to protect cells from damage, potentially reducing the risk of these conditions and promoting long-term health.
