Specifics of the septic system aeration process

septic system aeration

A home septic system is a water treatment system located on your property.  The main components usually include a pipe running from your house, a large septic tank, a drain field, and some septic systems include a pump for septic system aeration.

Step 1:  Waste water is sent to the septic tank

All wastewater from your home runs to a main pipe that carries it to the septic tank.  This includes water from sinks, toilets, dishwashers, showers, and washing machines. Because all the water from your house is going to an enclosed tank, you should be cautious about what solids or chemicals you send down the drain.  The size of the tank depends on the number of people who use it on a daily basis, but they are usually between 750 and 1,250 gallons. In a typical septic system, the tank is usually divided into 2 compartments, but if your system includes a Hiblow septic aerator, the tank usually has 3 compartments.  The tank is usually made of either concrete or fiberglass and is buried between a few inches and a few feet underground.

Step 2: Breakdown and separation of solids sometimes includes septic system aeration

In the first compartment of the septic tank, wastewater settles into three layers: fat and oil on top, liquid in the middle, and solids on the bottom. Most larger solids are left on the bottom of this first compartment where bacteria work to break them down.  In a typical septic system, the wastewater then flows to a second compartment where it settles further and anaerobic bacteria continue to break down solids until the process is complete.

Some septic systems include a Hiblow septic aerator in one of the compartments which adds oxygen to the tank.  This Hiblow pump allows bacteria to work aerobically (with oxygen), often making them more effective at helping to “clean” the wastewater.

Step 3:  Effluent is released from the home septic system

When the wastewater is cleared of solids and ready to leave the tank, the water that is left is called effluent.  The effluent flows or is pumped out of the tank and into a drain field.  The drain field is made up of rows of perforated pipes buried a few inches below the ground.  These pipes allow the water to drain into the soil. The soil filters the water and naturally occurring microbes help to clean it before it mixes with the groundwater.  The size of your drain field and its location on your property depends on the size of your septic tank, the type of soil in your yard, and the water table in your area.

Even though there are some slight differences depending on the construction of the system, the overall process of using an aeration septic system to filter the home’s wastewater is largely similar.
