Septic Tank Deodorizer

Are you experiencing foul odors coming from your septic tank? This is caused by the bacteria that break down the sludge and waste in your tank. Normally, this process is carried out by anaerobic bacteria. These bacteria do break down waste, but often produce that characteristic rotten egg smell in the process.

How does anaerobic decomposition occur in the tank?

Anaerobic bacteria develop in a septic tank as sludge accumulates on the bottom and forms a thick, oxygen-poor layer. In this sealed, airless environment, oxygen-consuming bacteria disappear, allowing anaerobic bacteria to take over. The sludge creates an ideal living environment for these bacteria, in which they can break down organic waste without oxygen.

Adding aerobic bacteria can help by speeding up the decomposition process and reducing odor—provided there is enough oxygen. This can be achieved using aeration systems, which improve the balance between aerobic and anaerobic processes and help reduce the volume of sludge.

Prevent odors with aerobic bacteria

To prevent anaerobic bacteria from breaking down waste, you need to outcompete them with aerobic bacteria. These also break down the waste in your tank, but without causing unpleasant smells. Our advice is to regularly add septic tank bacteria to maintain a healthy balance. This helps prevent both odors and blockages.
