When the aerator pump stops the level of treatment in the tank falls substantially, risking discharge of inadequately-treated efflulent into the drainfield. If floating solids are discharged into the fields the field life is reduced as field clogging is sped up. The best you can and should do is return the system to proper operation.
What are the benefits of an aerobic treatment unit system?
The benefits of an aerobic treatment unit system are: Can be used on smaller sized lots as drain field size is smaller Can be used on lots with poor or inappropriate soil conditions (see perc test) Can be used on lots with a high water table or close to a body of water like lake, river or creek.

Should air be leaking out of my aerobic system?
No, air should not be leaking out of your aerobic system and into puddles on the ground. It sounds as if maybe groundwater is leaking into the aeration chamber and flooding it - you need to have the system inspected and leaks fixed as well as to direct surface runoff away from the septic.
What do you need to know about aerobic treatment?
An aerobic treatment unit needs a regular supply of wastewater. To treat wastewater effectively, the unit needs to maintain a stable population of microbes.Any extreme influxes of wastewater flow or strength will impair the unit’s performance. Your system can be affected by the amount, strength, and timing of the wastewater entering it.
What do you do when your aerobic septic alarm goes off?
If the alarm happens to be going off, the best thing to do is to push the red button or switch on the alarm box. This will turn off the alarm. There should be a red light and a green light located somewhere on the alarm box. The green light means that the alarm has power and should always be on.
How do I know if my aerator is working?
Warning Signs of a Septic Air Pump Malfunction Poor Air Pressure – This is the most obvious sign that something is wrong with your system's aerator. If the tank's air pressure levels aren't normal, the aerator isn't pumping correctly pressurized oxygen into the tank.

What happens if septic aerator stops working?
If the aerator in your septic system stops working, your system will naturally turn from an aerobic environment to an anaerobic environment, a much slower, much less efficient environment for breaking down the solids in your system.
What happens when septic pump stops working?
If the pump does not appear to be working at all, does not respond to any tests and is not pumping effluent, there may be a wiring problem.

Why is my aerobic system beeping?
Aerobic Treatment Systems usually consist of an aeration device that can be an external air pump or air compressor, or an internal unit such as a shaft aerator or a submersible aerator. The cause of an alarm on aerobic systems is either the failure of the aeration device or high water level inside the tank.
What is an aerobic treatment unit?
Aerobic treatment units, also called activated sludge tanks, are a common method of biological treatment used in municipal wastewater treatment facilities. According to Chapter 73 of the PA Rules and Regulations, traditional septic tanks can be replaced with aerobic treatment tanks.

Conserve water to avoid overloading the system. Be sure to repair any leaky faucets or toilets. Divert all non-wastewater sources of water , like roof drains, house footing drains, and sump pumps, away from the aerobic system.
What is the middle of an aeration chamber?
The middle, or aeration chamber, is where air is pumped into the chamber to provide oxygen for the aerobic bacteria. The air is brought into the aeration chamber at the bottom and either flows freely throughout the chamber "suspended growth" (Fig. 2.) or flows through a "fixed film media" (the black block in Fig. 1). Figure 2.
Why are ATUs not used?
A major reason that ATUs are not more widely used is concern about operation and maintenance by homeowners. ATUs are not passive and therefore require regular maintenance, and inspection. Abuse or neglect can easily lead to component failure or unsatisfactory performance.
Can a septic tank be replaced with an aerobic tank?
According to Chapter 73 of the PA Rules and Regulations, traditional septic tanks can be replaced with aerobic treatment tanks. In some cases, where the treated wastewater must be discharged into shallow soils, an ATU may make it possible to eliminate further pretreatment units within the system. Aerobically treated wastewater permits ...
Is ATU better than septic?
The quality of effluent leaving an ATU is considerably better than that discharged from a septic tank. Therefore, owners of on-lot systems with an ATU may reduce the size of their absorption fields by one-third, thus requiring a smaller absorption field than would be required if a septic tank had been used.
How long does an aeration system last?
Say your aeration system is designed, constructed, and is operating for five to 10 years without any maintenance or service. You might have minor maintenance along the way, like changing the oil in your car, but over time, problems can occur in your aerobic wastewater treatment plant if your system is not generating the same amount of air.
What happens if there is too much sludge in the system?
If there is too much sludge being formed and not enough being removed, it builds up in the system, which means you’ll have excess solids going in your effluent, creating foul odors and septic conditions and putting your effluent out of compliance, unless you routinely waste, dewater, and discharge it.
Can aerobic growth system be made into a membrane bioreactor?
In this case, much less sludge is produced. You can also add a membrane and make your aerobic suspended growth system into a membrane bioreactor, and that would be much easier to separate the solids than clarification and you can recycle those solids or you can waste those solids in a much more controlled way.

Deeply-rooted shrubs and trees should not be allowed to grow within the dispersal field. Divert surface waters (runoff and water from gutters) away from the tanks and dispersal field. Keep heavy traffic like automobiles and heavy equipment off the dispersal field.
How does aerobic treatment work?
Aerobic treatment systems consist of several processes that work together to provide a high-quality effluent: Removal of gross solids (trash): After the wastewater leaves the house through a pipe, it enters a trash or septic tank, where the solids in the wastewater settle to the bottom or float to the surface.
How to select an aerobic treatment unit?
To select an aerobic unit, first determine the amount of daily wastewater flow from your home or small business. The rate of daily wastewater flow is based on the home’s square footage or number of bedrooms, whichever is larger (Table 1). Then choose a Class I aerobic treatment unit that can handle that amount of flow.

Why do we disinfect the effluent of a spray field?
For these systems, the effluent must be disinfected to reduce the risk of human exposure to pathogens. Although a spray field is like a lawn sprinkler, it should be viewed very differently. The water being distributed is treated wastewater—not drinking water. Residents and pets should avoid contact with it.
What happens if your aerator isn't working?
More often than not, this alarm does not indicate your aerator is failing and that your system is facing catastrophic failure.
What is a broken timer in aerobics?
Broken Timer: The timer in your aerobic system ensures water is not released until the effluent is clear and clean enough for your system’s next phase, whether being directly released or transferred to a seconda ry treatment system .
Why is aerobic septic system anaerobic?
Because an aerobic septic system outputs cleaner effluent, a much smaller secondary treatment system (if any) is required than would be needed for an anaerobic system.

What happens if a sewage pump fails?
Sewage Pump Failure: If the sewage pump fails, it will cause the water in your system to rise, signaling your septic alarm. You may need to replace or repair your sewage pump to restore your system to functionality. Inadequate Air Pressure: Proper air pressure is necessary in order for your aerator to adequately oxygenate your system.
Can a septic system be a secondary treatment system?
Because aerator septic systems typically have much smaller secondary treatment systems (and sometimes no secondary treatment system at all), your system will either begin discharging raw sewage directly into the environment or into the secondary treatment system.
