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.

Isoflurane is also notable for its cardiovascular stability. It causes dose-dependent hypotension, and while it can affect heart rate, it generally preserves cardiac function better than most other volatile anesthetics. This property is particularly advantageous for patients with pre-existing cardiovascular conditions. Moreover, its use in a controlled environment allows anesthesiologists to manage blood pressure effectively through various supplemental agents.
