Aerobic Treatment Units


What is an Aerobic Treatment Unit (ATU)?

Aerobic Treatment Units (ATUs) are innovative, eco-friendly wastewater treatment systems designed to process household wastewater efficiently. These units harness aerobic bacteria to break down waste, ensuring a cleaner, more environmentally friendly discharge.

Aerobic treatment units (ATUs) are advanced wastewater treatment systems that use oxygen to break down organic matter in sewage. They mimic the natural processes found in rivers and streams but operate in a more controlled environment. Here’s how they work:

  • Pretreatment: The wastewater first enters a pretreatment tank where large solids are settled out or retained.
  • Aeration: The pre-treated wastewater then flows into the aeration chamber. In this chamber, a pump or blower introduces air, providing oxygen to support the growth and metabolic activity of aerobic bacteria. These bacteria consume organic matter, transforming it into carbon dioxide, water, and biomass.
  • Settling: After aeration, the mixture moves to a settling or clarifying chamber where the biomass (mainly bacterial cells) settles out from the treated water.
  • Discharge or Further Treatment: The clarified water can be discharged if it meets local environmental standards or may undergo further treatment like disinfection before release.
  • The aerobic process efficiently reduces: Organic pollutants, BOD (biological oxygen demand), and pathogens, making it effective for areas lacking access to municipal sewage systems.

 Aerobic Treatment Units Frequently Asked Questions:

Aerobic Treatment Units (ATUs) are advanced onsite wastewater treatment systems designed to break down and treat sewage and other organic matter more efficiently than traditional septic systems. Here are some frequently asked questions (FAQs) about aerobic treatment units:

Q: What is an Aerobic Treatment Unit (ATU)?

A: An ATU is an onsite wastewater treatment system that uses oxygen to promote the growth of beneficial bacteria, which break down and treat sewage and organic waste more effectively than septic tanks.

Q: How does an ATU differ from a traditional septic system?

A: ATUs use oxygen to support aerobic bacteria, while traditional septic systems use anaerobic bacteria. ATUs are typically more efficient and can treat wastewater to a higher quality, making them suitable for smaller lots or sensitive environments.

Q: When is an ATU recommended or required?

A: ATUs may be recommended or required in areas with poor soil conditions, small lot sizes, high groundwater, or sensitive ecosystems. Local regulations and environmental concerns play a significant role in determining when ATUs are necessary.

Q: How does an ATU work?

A: ATUs introduce oxygen into the treatment process, allowing aerobic bacteria to thrive and break down organic matter more efficiently. This aerobic environment results in cleaner effluent.

Q: Are ATUs more expensive than traditional septic systems?

A: Yes, The costs vary depending on the brand and model of the ATU, site-specific factors, and local regulations.

Q: Do ATUs require regular maintenance?

A: Yes, ATUs require regular maintenance Every 6 months, per the Department of health, to ensure proper functioning. Maintenance typically includes monitoring oxygen levels, checking for mechanical issues, and periodic cleaning or replacement of components.

Q: What kind of electrical power is needed for an ATU?

A: ATUs require electricity to power components like air compressors and pumps. The power requirements can vary depending on the system’s size and design.

Q: Can ATUs be used in high-water tables or flood-prone areas?

A: ATUs can be suitable for high-water tables if properly designed. Flood-prone areas may require elevation or flood-resistant components to prevent damage.

Q: Can I retrofit an existing septic system with an ATU?

A: It’s possible to retrofit an existing septic system with an ATU, but it depends on the specific system, site conditions, and local regulations. Consult with a wastewater professional for guidance.

Q: Are there any restrictions on the use of an ATU for residential or commercial properties?

A: Local regulations, zoning laws, and environmental restrictions may dictate whether you can use an ATU on your property. It’s essential to check with your local health department or regulatory authority.

Q: Do ATUs eliminate the need for septic tank pumping?

A: ATUs often include a septic tank component, and regular septic tank pumping is still necessary to remove solid waste and maintain proper system function.
