Everything You Need to Know About ATU (Aerobic Treatment Units)

Understanding ATU (aerobic treatment units) can be slightly difficult. Some people refer to these units as aerobic septic systems, which is an incorrect term. An aerobic treatment unit is quite similar to a standard septic tank system. However, rather than using the anaerobic process that’s usually employed in septic systems, these use an aerobic process. Aerobic treatment units are mostly found in rural areas where access to proper sewage lines is limited. If public sewers are not available in a particular area, homeowners generally opt for aerobic treatment units or septic tank systems.

How Do They Work?

There are four main phases involved in ATU (aerobic treatment units). The first step is pre-treatment, in which large solids are removed from the water. The next stage is aeration, in which aerobic bacteria dissolve the biological waste in the water. The second-to-last stage is the settling stage, when all undigested solids and substances are allowed to settle. The final stage is the disinfection stage: a powerful disinfectant (usually chlorine) is used in the water to create an antiseptic effect.

Types

There are several different types of aerobic treatment units that you can choose from. The fixed film systems are the most common and are generally used in rural areas. However, you can also opt for a continuous flow, suspended-growth aerobic system or a retrofit system. The retrofit systems are portable and are typically smaller than their fixed film counterparts. If you want to get new ATU (aerobic treatment units) installed in your house, you should contact the plumber. The plumber will first ask about your water requirements and then recommend a suitable aerobic treatment system for your house. Installation doesn’t take more than a day, so you won’t have to wait long at all. To know more about aerobic treatment units visit Valley Isle Pumping. You can also connect with them on Facebook.
