How Long Does the Average Aerator Last in a Home Sewage Treatment System and What Causes Failure?

How Does An Aerator Work?

The function of aeration systems is to add oxygen to wastewater, which allows microorganisms to break down waste more quickly and efficiently than standard septic systems. There are 3 compartments in this system. The first is the pretreatment compartment, and this part functions pretty similarly to traditional anaerobic septic tanks. In this place, heavier particles settle at the bottom and lighter substances stay on the surface. After this step, the partially treated water goes to the aeration compartment, where an aerator oxygenates the water, which hastens the decomposition of the organic waste. The last compartment is the clarifier chamber, in which any leftover solids fall to the bottom and clean water moves on to a secondary treatment.

Average Lifespan Of An Aerator

When we’re talking about a life span, if you are talking about a well-maintained aerobic system, we expect it to last 3 to 5 years. However, with good care, certain ones have a much longer lifespan. Giving a specific age is quite hard because the actual lifespan is determined by a number of elements, including brand, model, usage intensity, and maintenance procedures, as well as other outside factors.

What Are Some Of The Factors That Can Cause The Failure Of The Aerator?

Faulty Wires: Wires of the aerator can be damaged or corroded over time, causing electrical difficulties. As a result, the aerator will eventually start creating trouble. So, if you see any damaged wires, call a professional septic company. 

Clogged Air Filter: Since an aerator provides oxygen, it naturally needs an air filter to keep dirt and impurities out of the system. If this filter becomes clogged, it can cause the aerator to fail.

Worn or Damaged Parts: An aerator has multiple components like bearings, seals, or impellers, which can get damaged over time and create aerator failures.
