Aerobic Sewage Treatment System

Aerobic septic systems, or ATUs, are essentially small, residential wastewater treatment facilities. They add oxygen to the septic system to encourage the growth of aerobic bacteria that break down the organic waste in the sewage. This results in a cleaner effluent.

The system’s aeration chamber introduces oxygen into the sewage, allowing bacteria to multiply and break down the waste. Solids fall into a clarifier and are recirculated to the aeration chamber. The effluent, now free from organic waste and therefore odorless, rises into a chlorinator for disinfection. Once chlorinated, the now clean water moves to a holding chamber to be discharged later.

ATUs provide a septic tank alternative for sites where a conventional drain field can’t be installed, making it possible to have wastewater treatment at sites with even the most difficult soil or topographical conditions.

Drip Distribution System

A drip distribution, or drip disposal, septic system is similar in structure to a conventional septic system, but it includes an aerobic pre-treatment chamber and filtering device to further treat the wastewater. The treated water is then sent to an array of drip irrigation tubes to distribute the water over a large area. This water is clean enough to use for irrigating a lawn or non-edible plants. Plants remove excess nitrogen from the water, further purifying it.

Advanced Material Media Filtration

These systems use materials such as sand, peat or synthetic textiles to filter effluent before it is released into the leach field. Not only can these be installed where conventional systems cannot be, they’re also less expensive in locations where gravel isn’t readily available.

Mound Septic System

Mound and raised bed septic systems are like conventional systems, except that the soil is specially prepared to create an area where the effluent is treated. The sand-lined filter bed is one of the most popular choices. In this system, small distribution pipes are set into a layer of gravel that sits over a layer of sand. The whole area is covered completely with topsoil to form a mound.

Plastic Leach Field Chamber

This system uses a standard septic tank, but instead of the conventional pipe leach field, the leach field is made of interlocking polyethylene arches that provide a continuous drainage area. The chambers create an empty space for the effluent to flow through, so there’s no need for gravel or geotextile.
