Anaerobic digestion breaks down organic matter in the sewage treatment process through natural decomposition. A wide variety of materials can be processed in anaerobic digesters, producing methane gas that can be recovered and used as an energy source.
Formula 12 is a specialized blend of high-performance microorganisms designed for the biological treatment of fats, oils, and grease in anaerobic digesters. It contains surface tension depressants and penetrants that loosen and liquefy heavy grease deposits, facilitating their biodegradation. This fully biodegradable product is safe for both people and the environment.
