Introduction

Aerobic septic systems are an alternative to traditional anaerobic systems. They utilize oxygen-loving bacteria to break down organic waste more efficiently, resulting in a cleaner effluent. However, homeowners may notice odors coming from their aerobic septic systems, which can be a cause for concern. We will explore the article: Do Aerobic Septic Systems Smell?

Understanding Aerobic Septic Systems

Aerobic septic systems rely on the presence of oxygen to facilitate the decomposition of waste. These systems typically consist of a treatment tank, an aerator or septic air pump, and a drainfield. The aerator introduces oxygen into the system, promoting the growth of aerobic bacteria that break down the waste effectively.

The Role of Aerators in Aerobic Septic Systems

The aerator, also known as the septic air pump, plays a vital role in the functioning of septic system aeration. It supplies a continuous flow of air into the treatment tank, ensuring that the aerobic bacteria have the necessary oxygen to thrive. Without a properly functioning aerator, the system can become problematic, leading to foul odors.

Lack Of Oxygen: A Common Cause Of Odors

If the septic air pump or aerator stops functioning for an extended period, usually around 14 days, the aerobic bacteria within the system can die. As a result, the septic system transitions from aerobic to anaerobic, where anaerobic bacteria take over the decomposition process. Anaerobic digestion produces methane and hydrogen sulfide gas, which have distinct odors.

The Difference Between Aerobic And Anaerobic Bacteria

Aerobic bacteria thrive in the presence of oxygen and are highly effective at breaking down organic waste, resulting in a cleaner effluent. On the other hand, anaerobic bacteria operate in environments with little to no oxygen. They digest organic waste differently and produce by-products such as methane and hydrogen sulfide gas, which contribute to foul odors.

The Odor Of Hydrogen Sulfide Gas

One of the gases produced by anaerobic digestion is hydrogen sulfide, which has a strong odor resembling rotten eggs. If you detect this smell around your aerobic septic system, it is a clear indication of a malfunctioning aerator or a shift to anaerobic conditions within the system.

Identifying A Malfunctioning Aerator

To determine if your septic air pump or aerator is malfunctioning, there are a few signs to watch out for. These include:

  • Strong Odor: A foul smell, particularly the smell of rotten eggs, around your aerobic septic system indicates a malfunctioning aerator. This odor is caused by the release of hydrogen sulfide gas.
  • Unusual Noise: If your septic air pump is making unusual or loud noises, such as grinding, rattling, or screeching sounds, it may indicate a struggling or malfunctioning aerator. Unusual noise can be a result of mechanical issues or worn-out parts.
  • Alarm System: Many aerobic septic systems are equipped with alarm systems that notify homeowners of any issues. If your alarm is constantly sounding or has gone off, it may be due to a problem with the aerator.
  • Visual Inspection: Check the aerator for any visible signs of damage, such as broken parts or disconnected power supply. Additionally, inspect the air diffuser to ensure it is clean and free from clogs.
