How does septic tank work?: Septic tank material:
Septic tanks can be made of different materials BUT the 2 basic materials are concrete and poly. poly is a plastic and can come in different colors. Blue, Green, and Black poly waste tanks are the popular colors. The black poly septic tanks may be designed to be above ground and take the weather.
Fiberglass waste tanks:
Fiberglass waste tanks are popular for Aeration Treatment Units. Aeration Treatment Units are mini sewer treatment plants that breed the good septic bacteria that help keep your drain field clean and working. Aeration Treatment Units and very good for the environment when installed and operated properly.
The septic baffle:
With each type of septic tank, there is at least one baffle to stop or slow down the waste that enters from the home or building, The septic baffle is the main filtering device in a waste tank, and I say second to a septic tank filter. Your septic tank is a giant filtering device that keeps your drain field clean. There can be multiple baffles in a septic tank. The septic baffle and the septic tank filter are the environment’s best friends.
The journey of human waste thru a septic tank.
Wastewater comes in from the main septic waste line and enters the septic tank. The waste at this point may hit a drop tee or just hit the baffle. You can have both.
The first step of filtering the septic waste is very important. Septic bacteria must start their work of breaking down the waste. This will take some time to break down. It may take a day to weeks to months and even years for non-human waste to break down.
Mother Nature makes her own rules on speed. You as the septic tank owner must make her happy. A monthly dose of septic tank bacteria that she approves of and your tank, may perform like it was sized for. We suggest BioForce Bacterial Waste Liquefier. It is a low cost septic tank treatment.
The baffle can be 2 feet off the wall of the waste coming in to in the tank or in the middle of the tank. There can even be another baffle 2 feet before the septic tank tee leaves the waste tank. The septic tank space between the baffles is where the waste gets broken down to a liquid state and what is floating or has sunk down to the bottom of the tank will still be broken down to a liquid that can pass the next baffle and go thru a septic tank filter in the tee leaving the tank.
This is why adding once a month a septic tank product called BioForce Bacterial Waste Liquefier to keep your septic tank operating at it’s best.
Septic tank bacteria will work 24/7 to break down the waste. This is why it is absolutely important to use a septic tank product every month and limit your use of anything that is “Anti Septic”.
A septic tank before an aeration treatment unit is also called a “Trash Tank” and the above process will still happen. Another septic tank after the trash tank is where an aeration treatment unit will be.
