Aerobic Treatment Unit (ATU)

An Aerobic Treatment Unit uses oxygen to help bacteria break down waste. The process involves three main steps:

  1. Pre-Treatment: Solids settle and grease floats in the first chamber.

  2. Aeration: Air is pumped in, encouraging aerobic bacteria to digest pollutants.

  3. Clarification: Remaining solids settle out, leaving clean water ready for dispersal.

Benefits:

  • Removes more organic matter and pathogens than traditional systems.

  • Fits small properties due to smaller drainfields.

  • Protects groundwater and improves wastewater quality.

ATUs require routine maintenance every 3 to 6 months. Inspections, air pump checks, and filter cleaning are essential. Installation costs typically range from $10,000 to $20,000. Ongoing operation costs are higher than conventional systems because ATUs need electricity and regular upkeep.

Tip:
Choose an ATU if you want a reliable, environmentally friendly solution and have limited yard space.

Sequential Batch Reactor (SBR)

A Sequential Batch Reactor treats wastewater in timed cycles. The system fills with wastewater, treats it using aeration and settling, then discharges the clean water.

Pros:

  • Delivers high treatment efficiency.

  • Handles variable flows well.

  • Suitable for homes with fluctuating water use.

Cons:

  • Requires careful monitoring and control.

  • Needs regular maintenance and skilled servicing.

Estimated Costs:
SBR systems usually cost between $12,000 and $25,000 to install. Maintenance costs depend on system complexity and frequency of use.

Moving Bed Biofilm Reactor (MBBR)

The Moving Bed Biofilm Reactor uses small plastic carriers suspended in water. These carriers provide a surface for bacteria to grow and treat the wastewater as it flows through the tank.

How It Works:
Biofilm carriers move freely in the reactor. Bacteria on the carriers break down organic matter. Aeration keeps the carriers moving and supplies oxygen.

Advantages:

  • Effective treatment and adaptability.

  • Maintains high sludge concentrations, improving efficiency.

  • No need for sludge return equipment, making it easier to operate.

Disadvantages:

  • Performance depends on proper design and operation.

  • Energy consumption for aeration can be significant.

  • Maintenance includes reactor upkeep and occasional carrier replacement.

Estimated Costs:
Capital costs include the reactor, installation, and electrical connections. Operational costs focus on energy for aeration and maintenance. For small homes, MBBR systems can be cost-effective, especially when combined with membrane filtration.

Conventional Septic Tank

A conventional septic tank is the most common system for rural homes. Wastewater from the house enters the tank, where solids settle to the bottom and oils float to the top. Anaerobic bacteria break down the solids. The liquid then flows to a drain field for further treatment in the soil.

Pros:

  • Lower installation and maintenance costs.

  • Independence from municipal sewage systems.

  • Long lifespan with proper care.

  • Suitable for remote or rural locations.

Cons:

  • Requires regular pumping and maintenance.

  • Risk of leaks or backups if neglected.

  • Limited capacity for larger households.

  • Local regulations may restrict installation.

Estimated Costs:
Installation ranges from $2,500 to $6,000, but can reach $12,000 in some areas. Pumping every 2 to 5 years costs $200 to $500.
