Understanding The 3 Tank Aerobic Septic System: A Comprehensive Diagram

What is a 3 Tank Aerobic Septic System?

Definition of a 3 Tank Aerobic Septic System

A 3 Tank Aerobic Septic System is a wastewater treatment system that uses the natural process of aerobic bacteria to break down and treat sewage. Unlike conventional septic systems, which rely on anaerobic bacteria, the aerobic septic system introduces oxygen into the treatment process, allowing for more efficient decomposition of organic matter.

Components of a 3 Tank Aerobic Septic System

A 3 Tank Aerobic Septic System consists of three main components: the primary tank, the aeration tank, and the clarifier tank. The primary tank is where the initial settling of solids occurs, separating the heavier solids from the wastewater. The aeration tank is where the aerobic bacteria thrive, breaking down the organic matter through oxygenation. Finally, the clarifier tank is responsible for further separating the clarified effluent from any remaining solids before it is discharged.

How Does a 3 Tank Aerobic Septic System Work?

Aerobic Bacterial Processes

The key to the 3 Tank Aerobic Septic System’s functionality lies in the aerobic bacterial processes that take place within the system. Unlike anaerobic bacteria, which thrive in oxygen-deprived conditions, aerobic bacteria require oxygen to survive and perform their role in wastewater treatment. With the introduction of oxygen, the aerobic bacteria are able to break down the organic matter much more efficiently, resulting in a higher treatment efficiency.

Each Tank’s Role in the System

Each tank within the 3 Tank Aerobic Septic System has its own specific role in the treatment process. The primary tank serves as the first stage of treatment, allowing for the separation of solids from the wastewater. The aeration tank is where the aerobic bacteria are introduced and where the majority of the treatment occurs. Finally, the clarifier tank serves as the last stage of treatment, allowing for the further clarification of effluent before it is discharged.

Flow of Wastewater in the System

The flow of wastewater within a 3 Tank Aerobic Septic System is a carefully designed process. Initially, the wastewater enters the primary tank, where the heavier solids settle at the bottom and are retained, while the lighter scum floats to the top. The partially clarified wastewater then flows into the aeration tank, where the aerobic bacteria are introduced. In this tank, the wastewater is continuously mixed and aerated, allowing the bacteria to decompose the organic matter. Finally, the clarified effluent flows into the clarifier tank, where any remaining solids settle to the bottom, and the clear effluent rises to the top for discharge.

Advantages of a 3 Tank Aerobic Septic System

Higher Treatment Efficiency

One of the main advantages of a 3 Tank Aerobic Septic System is its higher treatment efficiency compared to traditional septic systems. The aerobic bacteria thrive in the presence of oxygen, allowing them to break down the organic matter more effectively. This results in a higher level of treatment, reducing the contaminants in the wastewater and producing a cleaner effluent.

Reduced Nitrate Levels

Another advantage of the 3 Tank Aerobic Septic System is its ability to reduce nitrate levels in the effluent. Nitrate, a common contaminant found in wastewater, can be harmful to human health and the environment. The aerobic bacteria in the system convert the nitrogen compounds present in the wastewater into harmless nitrogen gas, thus reducing the nitrate levels in the effluent.

Lower Maintenance Requirements

Compared to conventional septic systems, 3 Tank Aerobic Septic Systems have lower maintenance requirements. The continuous aeration and mixing in the aeration tank help prevent the buildup of solids and scum, reducing the frequency of tank cleanings. Additionally, the aerobic bacteria in the system digest the organic matter more efficiently, resulting in less frequent pump-outs.

Installation and Set-Up of a 3 Tank Aerobic Septic System

Determining Proper Location

When installing a 3 Tank Aerobic Septic System, it is crucial to determine the proper location for the system. Factors such as soil type, groundwater level, and proximity to water sources need to be considered. The system should be installed in an area with well-drained soil and at a safe distance from water sources to minimize the risk of contamination.

Excavation and Tank Placement

The installation process involves excavating the area for the tanks and properly placing them. The primary tank should be placed at the inlet of the system, followed by the aeration tank and the clarifier tank in sequential order. Each tank should be level and securely placed to ensure proper functionality.

Connecting the System to the Household Plumbing

Once the tanks are in place, the next step is to connect the system to the household plumbing. This involves diverting the wastewater from the home’s plumbing to the primary tank of the aerobic system. Proper plumbing connections need to be made to ensure the wastewater flows smoothly into the system.
