Aerobic Treatment Units (ATUs) are multi-chamber tanks that apply a series of processes to treat wastewater. An ATU is nearly similar to a conventional septic system in that it uses natural methods to treat wastewater. However, unlike conventional systems, ATUs also use oxygen to break down organic matter in a scaled-down version. ATUs are mostly used in areas where conventional, or gravity flow septic systems cannot be used. Since ATUs break down organic matter fast, the wastewater leaving the tank is cleaner. Here are some of the commonly asked questions about an atu in Maui.
How does an ATU work?
Wastewater enters the first tank, where heavy solids are removed via gravity. The clarified water then moves into the aeration tank where it is mixed with oxygen. This creates an environment where bacteria digest the biological waste. In this stage, much of the nitrogen in the wastewater is also removed. Finally, the effluent from the aeration chamber is pumped into a clarifier. Here, biological solids settle to the floor, and the treated water is pumped out of the tank to an absorption field.
What are some typical ATU maintenance practices?
Monitoring and maintenance are vital to the performance and durability of an ATU. Since ATUs are more complicated than the conventional systems, it is important to hire a certified ATU contractor to carry out the necessary maintenance. Some typical ATU maintenance practices include:
* Checking clarity of effluent
* Examining and cleaning filters on the aerator
* Inspecting electrical panel for functioning alarms
* Recording sludge level in the pretreatment and aeration tanks and refilling them when needed
* Quarterly fecal coliform testing for tanks with a disinfection unit
What are the main advantages of ATUs?
According to the Environmental Protection Agency, the primary benefits of ATUs include:
* Higher level of wastewater treatment than conventional systems
* Helps to protect water resources in areas of failing septic units
* Ideal for locations where septic systems cannot be installed
* Helps to extend the life of drain field
These are just some essential details to know about an ATU in Maui. It is important to hire a certified ATU specialist, to ensure that the new Aerobic Treatment Unit is installed correctly and within the set budget.
