All septic tanks are aerated either one way or the other.
That is because there are three types of bacteria in every septic system which process waste: aerobic, facultative and obligate anaerobic.
Aerobic bacteria require oxygen (compressed air) and are more aggressive/effective than anaerobic bacteria (which do not require oxygen). Typically there are very few of these type of bacteria in your septic tank. In a conventional septic system most of the bacteria are facultative.
Facultative bacteria also require oxygen but they can get it from non-aerated water by stripping oxygen molecules from other sources which directly produce the "rotten egg odor," also known as hydrogen sulfide gas (H2S). If you aerate the facultative bacteria they will stop producing the H2S and odor, and only produce an earthy smell like dirt.
There are now solar powered aerators available as after market products to eliminate H2S odor by directly aerating the influent flow in the septic tank and supplying the facultative bacteria with oxygen. Just place the air diffuser near the incoming or influent end of the tank. There is a solar aerator that is sized to minimize mixing and solids suspension in your treatment tank. Unlike high air flow, line power aerators, no effluent filter is required, because no matter where you put the diffuser in the septic tank no solids are suspended.
In the presence of oxygen, these bacteria are 20 times more aggressive at consuming waste materials.
Under aerated conditions the treatment in the tank is increased and effluent leaving the tank will be cleaner, this in turn takes the load off the soil treatment area improving overall life of the system.
With a solar septic tank aerator you never pay a power bill. Standard line power electric units require a electrician to install, will cost you more than $500.00 yearly for electricity and need elaborate ground fault protection to meet safety codes.
Solar septic tank aerators are an easy way to aerate any septic tank from the surface. They are designed for outdoor use. A well designed system has a self positioning diffuser with float, you simply drop the diffuser attached to the float and weighted bubble tubing in the septic tank influent inspection opening. Oxygen transfer is sufficient to treat up to 500 gallons per day of flow. This is equal to taking 15 ten minute showers, 5 loads of laundry, and 25 flushes per day, at a waste strength of 100 mg/l BOD. Other applications include placing diffuser in the septic tank wet wells, effluent distribution boxes, pumping chambers, dosing pits, and overloaded "dry wells."
Air flow is automatically managed by diffuser and included float system so air is completely dissolved, off gassing is odor free, and suspended solids treatment and removal is enhanced.
Check for a solar aerator system that includes one pole mounted linear air pump, integral solar panel, flex cap non-plugging coarse bubble mixing diffuser with float, and 20 foot of ¼ inch flex weighted tubing. System suitable for replacement of other advanced aerobic 500 gallon per day units. Seek a system with manufacturer 1 year warranty on all parts, 3 year warranty on pump motor, 5 year warranty on solar panels, 180 day money back warranty, system that is extremely quiet & efficient, free shipping, no sales tax except in Illinois!
