One of the improvements that have been made in septic systems is the method of introducing dissolved oxygen into the septic tank. This process is called “Aeration”. Septic tanks have been around for over 150 years but it wasn’t until the 1950’s that aeration was implemented in residential tanks.
So why aeration? Simply put, aeration supports the growth of aerobic bacteria. You can learn about aerobic bacteria here. When you understand the importance of aerobic bacteria you’ll understand why aeration is so important. It goes something like this. As more dissolved oxygen is added to the system, more aerobic bacteria can live which in turn consume more organic matter which results in a cleaner quality effluent and ultimately a more efficient system.
Aeration is typically achieved through the use of a pump or aerator. As you’ll see, there are various aerator types and we’ll discuss those in another article.
