How Does an Aerobic Sequence Batch Reactor Work?

What Is It?

A sequencing batch reactor (SBR) is a type of activated sludge process for the treatment of wastewater. In other words, these reactors break down organic waste with natural processes. Generally, SBR’s are used as part of a treatment plant’s system with multiple reactors working on batches of wastewater from general sewage or large facilities.

How Does It Work?
The “aerobic” part of the name indicates the use of oxygen. Air is bubbled through the wastewater to activate the bacteria that breaks down organic material. After this material is reduced to harmless compost, it sinks to the bottom of the tank to be deposited later. The clear, safe water can then be used for irrigation or just discharged.

Why Is It Important?
Treatment plants handle large volumes of waste. Aerobic SBRs are environmentally safe and can process waste without using harsh chemicals. SBRs can also be designed to handle different volumes of waste over different amounts of time, helping the plant operate more efficiently.

How Are We Taking Advantage?
In our plight to help the environment, we are doing our part to take advantage of this technology. A step further in this process is to add a methane digester and a generator. Our sister company, Kline’s Services, based out of Pennsylvania, has entered phase 2 of its Renewable Energy System Project by using a methane digester to turn organic waste into biogas. The biogas is then used to fuel engine generators that produce up to 600kW of electricity all year round. According to their results, this is 4 times more power than Kline’s Services needs to function. The excess is siphoned off to a substation on the property and cycled back into the system, saving money and resources.
