What is an Aerobic Septic System?

An aerobic septic system, also known as an aerobic treatment unit (ATU), is a wastewater treatment system that uses oxygen to break down and treat organic matter in the effluent. Unlike traditional septic systems that rely on anaerobic bacteria, aerobic systems encourage the growth of aerobic bacteria, which thrive in the presence of oxygen.

How Does an Aerobic Septic System Work?

1. Initial Treatment: The wastewater from your household is directed to the first chamber of the aerobic septic system, known as the primary treatment tank. Here, the solid waste settles at the bottom, while grease and lighter solids float to the surface. This initial settling process helps to separate the solids from the liquid effluent.

2. Aeration: Once the wastewater has passed through the primary treatment tank, it moves to the second chamber, called the aeration chamber. In this chamber, air is continuously pumped and mixed into the wastewater to provide oxygen for the aerobic bacteria. These bacteria then metabolize and break down the organic matter present in the effluent, converting it into simpler compounds.

3. Clarification: After the aeration process, the partially treated wastewater enters the clarifier tank. Here, any remaining solids settle to the bottom, forming a sludge layer. The clarified effluent is then discharged into a drainfield where further treatment occurs.

4. Advanced Treatment in the Drainfield: In the drainfield, the effluent is distributed evenly through a network of perforated pipes buried in trenches or beds. As the effluent percolates through the soil, it undergoes additional treatment by natural processes. The soil acts as a biological filter, further reducing harmful substances and pathogens in the wastewater before it is returned to the groundwater.

Benefits of Aerobic Septic Systems

Aerobic septic systems offer several advantages over traditional septic systems. Here are some key benefits:

  • Superior Treatment: Aerobic systems provide more efficient treatment of wastewater, resulting in cleaner effluent. The use of aerobic bacteria allows for the breakdown of a wider range of organic matter, including oils and fats.
  • Reduced Health Risks: The aerobic treatment process significantly reduces the concentration of harmful pathogens and bacteria in the effluent, reducing the risk of waterborne diseases and contamination.
  • Increased Longevity: With proper maintenance and regular servicing, aerobic septic systems have a longer lifespan compared to traditional septic systems.
  • Smaller Footprint: Aerobic systems take up less space than anaerobic systems, making them suitable for properties with limited land availability.
  • Environmentally Friendly: The advanced treatment provided by aerobic systems helps protect the environment by preventing groundwater contamination and reducing the pollution of nearby water bodies.

    • Maintenance and Care

    While aerobic septic systems are highly effective, they do require regular maintenance to ensure optimal performance. Here are a few maintenance tips:

  • Regular Inspections: Schedule regular inspections to check for any signs of damage, leaks, or malfunctioning parts.
  • Pumping: The primary treatment tank of an aerobic septic system will require periodic pumping to remove accumulated solids and sludge.
  • Cleaning and Declogging: Ensure that the aeration chamber and air pump are regularly cleaned to prevent clogging and ensure proper oxygen supply.
  • Bacterial Tablets: Some aerobic systems may require the addition of bacterial tablets to maintain a healthy bacterial population in the system.
  • Proper Waste Disposal: Avoid introducing non-biodegradable or harmful substances such as chemicals, oils, or medications into the septic system.

    • Conclusion

    Aerobic septic systems provide an efficient, environmentally-friendly way to treat wastewater. By harnessing the power of aerobic bacteria, these systems ensure superior treatment and minimize the impact on the surrounding ecosystem. Regular maintenance and care are essential for the long-term functioning of aerobic septic systems, allowing them to continue providing safe and reliable wastewater treatment for years to come.
