One of the key factors in ensuring its functionality is the presence of various types of septic enzymes. These enzymes play an essential role in breaking down organic waste matter, enhancing the natural bacterial activity within the system, and preventing clogs and backups. In this article, we will explore the most common types of septic enzymes and their functions.

1. Lipase Enzymes:

Lipase enzymes are responsible for breaking down fats, oils, and grease (FOG) that may enter your septic system. FOG is a common byproduct of cooking and can accumulate over time, clogging drains and causing blockages. Lipase enzymes work by breaking down the molecular structure of FOG into smaller particles, making it easier for bacteria to digest, and preventing the accumulation of scum in the tank.

2. Protease Enzymes:

Protease enzymes are specifically designed to break down proteins found in household wastewater. These enzymes are highly effective in breaking down proteins that can potentially cause clogs and septic system malfunctions. By breaking down proteins into amino acids, protease enzymes help maintain a balance of microbial activity in the septic system.

3. Amylase Enzymes:

Amylase enzymes are designed to break down complex carbohydrates such as starches and sugars. These enzymes help prevent the build-up of heavy, solid materials that can clog drains and pipes. By reducing the size and complexity of these substances, amylase enzymes facilitate their digestion and decomposition by bacteria within the septic tank.

4. Cellulase Enzymes:

Cellulase enzymes are responsible for breaking down cellulose, which is commonly found in toilet paper, tissues, and other plant-based materials that enter the septic system. Cellulose is a complex molecule that can be difficult to break down naturally. However, cellulase enzymes work by breaking the bonds within cellulose molecules, allowing bacteria to digest and decompose them more effectively.

5. Hemicellulase Enzymes:

Hemicellulase enzymes work hand in hand with cellulase enzymes to break down plant-based materials that enter the septic system. These enzymes can efficiently degrade hemicellulose, which is another complex carbohydrate found in various household waste substances. By breaking down hemicellulose, these enzymes help maintain the flow and functionality of your septic system.

6. Urease Enzymes:

Urease enzymes are responsible for breaking down urea, a common waste product found in urine. Waste material containing urea can lead to excess nitrogen in the septic system, which can harm the various biological processes responsible for treating wastewater. Urease enzymes work by converting urea into ammonia and carbon dioxide, minimizing the impact of excessive nitrogen in the septic system.

7. Phosphatase Enzymes:

Phosphatase enzymes play a vital role in breaking down organic phosphates present in wastewater. Phosphates can accumulate over time and cause issues such as eutrophication in water bodies when they enter the environment. By breaking down organic phosphates into smaller compounds, phosphatase enzymes prevent these substances from negatively impacting the overall health of your septic system and surrounding environment.


Septic enzymes are essential for the proper functioning of your septic system. Different types of enzymes work together to break down a wide range of organic waste materials, promoting microbial activity, preventing clogs, and ensuring the efficient treatment of wastewater. By understanding the functions of these enzymes and using septic products that contain them, you can help maintain a healthy and trouble-free septic system for years to come. Regular maintenance and enzyme treatments can go a long way in prolonging the lifespan and optimizing the performance of your septic system.
