Advanced Treatment Systems
- Advanced Treatment may include physical or chemical processes.
- Often referred to as: Advanced Treatment Systems (ATS) or Advanced/Aerobic Treatment Units (ATU’s).
- ATU’s utilize aeration and manipulation of bacteria in order to biologically treat waste water to higher standards than a conventional primary treatment system.

Unlike chemical approaches to water disinfection, UV light provides rapid, effective inactivation of microorganisms through a physical process.Sep 1, 2020
Which bacteria is used in aeration tank?
With a normal influent load of pollutants, the dissolved oxygen content in the aerated section of most plants should be kept between 3 and 5 MG/L. Anaerobic bacteria are normally used in an anaerobic digester to reduce the volume of sludge to be disposed of and to produce methane gas.Jun 14, 2012
Is sewage and wastewater the same?
Sewage is the part of wastewater that is contaminated with feces or urine, but is often used to mean any wastewater.
What is an ATU?
Advanced Treatment Units (ATUs), referred here to as an individual residential system, are small biological treatment systems used to treat wastewater to a higher degree than a traditional septic system. They are ideal for small sites and difficult soils.
Why would I need or want an ATU versus a traditional septic system?
ATUs are used in many states to achieve a higher-quality wastewater than what exits traditional septic tanks. In fact, they are necessary in some areas — either because of the sensitivity of the environment, or because of site conditions. ATUs are also designed to reduce nutrient loadings, whereas traditional septic systems are not.
What is the required maintenance?
As with all septic systems, an ATU’s proper functioning relies on regular maintenance. Due to its advanced components, an ATU needs more maintenance than a traditional septic system.
What is anaerobic treatment?
Conventional septic tank treatment is anaerobic, which means it is done in the absence of oxygen. ATUs use oxygen to foster the growth of bacteria that thrive in oxygen-rich environments. These bacteria break down and digest the wastewater inside the ATU as they are suspended in the liquid.
How is nitrogen removed from a septic system?
Treatment systems for nitrogen removal are generally done through a sequential process that mimics the natural nitrification/denitrification process using engineered systems. The first step in the sequence uses aerobic processes to transform the organic nitrogen and ammonia products in the septic tank effluent to nitrates and nitrites, which is the nitrification step. A variety of treatment devices can be used to accomplish this aerobic process, such as sand, gravel filters or ATUs.
Where is treated effluent collected?
Treated effluent is collected at the bottom and returned to the recirculating tank where the cycle begins again. After the effluent has gone through the filter several times, a controlling mechanism sends the effluent to the soil for final treatment.
What are the different types of aerobic treatment units?
What to know when choosing an aerobic treatment unit. There are three basic aerobic treatment unit operation styles: suspended growth, fixed-film reactor and sequencing batch reactor. All three types usually have a septic tank ahead of them that separates large solids.
What is sand used for in a septic system?
Sand is commonly used as a filter media . Effluent from the septic tank flows into a pump tank and is evenly applied over the sand surface. A timer is used to dose the entire surface of the filter intermittently. This draws oxygen from the atmosphere through the sand medium and its attached microbial community.
How does UV radiation kill pathogens?
The most common method for final treatment used in on-site systems to remove harmful pathogens is ultraviolet radiation. The germicidal properties of UV irradiation have been recognized for many years. The radiation penetrates the cell wall of the organism and is absorbed by cellular materials, which either prevents replication or causes the death of the cell. The water must be relatively free of turbidity for UV radiation to effectively reach and destroy the organism. Because UV light has a limited distance to be effective, the most disinfection occurs when a thin film of water is exposed for treatment.
What is an AX20 system?
AX20 Treatment Systems are primarily intended for residential applications that require an advanced secondary treatment system, including new installations, retrofits, or repairs. They’re also used in small commercial applications. AX20 units are ideal for sites with poor soils and small sites, especially those that require a compact “filter on top of tank” configuration.
How many gpd does an AX20 pod treat?
A single AdvanTex AX20 pod treats wastewater flows of up to 500 gpd (1890 L/day). AdvanTex Treatment Systems are modular, however, and can be installed in multi-pod arrays to handle higher flows.
Why is wastewater treatment important?
Advanced wastewater treatment is necessary as society mitigates the impacts of increased population, urbanization, industrialization, and the depletion of potable water. Wastewater treatment can not always treat wastewater efficiently, which can generate a number of concerns including odor issues and health problems.
What is advanced wastewater treatment?
The American Institute of Chemical Engineers defines advanced wastewater treatment as “any process that can reduce impurities in wastewater below [what is] attainable through conventional secondary or biological treatment.”.
What happens if a septic tank leaks?
Leaking tanks pollute your yard and the groundwater. They also allow groundwater to flow into your tank, which overloads your drainfield and shortens its life. Your septic tank also needs to have access risers to-grade (showing above the ground) that are equipped with durable, bolted lids.
What is an orenco treatment system?
Orenco’s AdvanTex ® Treatment Systems provide environmentally sustainable treatment of residential wastewater flows. They’re the ideal solution for difficult soils, small sites, system upgrades and repairs, new installations, pretreatment, nitrogen reduction, and disinfection. One of the major benefits of AdvanTex is that it provides, consistent, reliable advanced treatment under real-world conditions, not just in a controlled testing environment. And one reason for that is AdvanTex Treatment Systems process and discharge small amounts of treated wastewater throughout the day, so surges don’t overwhelm your system. The treated effluent is so clean it can be reused for subsurface irrigation (where regulations allow) or discharged to shallow, inconspicuous trenches.

Constructed Wetlands
- A constructed wetland is a basin or a cell that is constructed specifically to treat wastewater. It contains microorganisms, culture media, and plants that serve the function of treating the incoming effluents. If the constructed wetland is supposed to collect subsurface flow, a layer of graded gravel media or porous media is filled in the cell to resist the corrosive and dissolving wa…
Lagoon Or Stabilization Pond
- Lagoon is used either as a final treatment and dispersal option for wastewater or as one of the methods in advanced pretreatment of wastewater. The technique is preceded by a septic treatment system to remove large solids. Lagoon is a large basin of wastewater that treats the wastewater through chemical, physical and biological treatment processes. This process conver…
Media Filter
