Why is Aeration Used in Wastewater Treatment?

Aeration is one of the most common processes used in wastewater treatment and it’s an effective and naturally occurring method that can be harnessed in commercial wastewater systems of all types and sizes. The process of aeration involves adding air to wastewater, to promote microbial growth, which in turn breaks down organic matter and gets rid of contaminants in the water. This type of treatment can be used on its own or as a supplement to other processes, such as primary sedimentation and secondary treatment.

How does aeration treat wastewater?

At the most basic level, aeration helps break down organic matter in order to remove contaminants from your water by using extra oxygen. Aeration systems typically work by pumping air full of oxygen into a tank filled with wastewater; this activates the naturally occurring microorganisms which then go about performing aerobic biodegradation. Aerobic biodegradation of organic matter is far quicker and more practical than leaving the wastewater to degrade under septic conditions. The naturally occurring bacteria present in the wastewater decompose the organic matter present into carbon dioxide and water through a complex process of oxidation reactions.

How does an aeration system work?

An aeration system is typically a type of wastewater treatment that utilises air to increase the rate of bacterial growth. The main component of an aeration system is a pump to transport air from outside the tank into it. This enables us to get around one problem with traditional aeration systems: when we add more air to these tanks, it simply becomes mixed up with existing water that doesn’t contain much-dissolved oxygen. By pumping outside air into the tank, this problem is avoided. Air supply is achieved by either using a compressor or utilising tanks that allow for easy entry and exit for gas-producing microorganisms.

Why are aeration systems important?

Wastewater TreatmentOrganic matter in wastewater needs to be removed quickly and economically because it is detrimental to human health as well as being unsightly and even smelly at times! The main component of an aeration system is a pump that can transport air from outside the tank into it and some way of distributing oxygen evenly throughout the water.

Setting up an aeration wastewater treatment system

If it were not for the activated sludge process, which aerates water through pumps and piping to release oxygen into the water, an ample and evenly distributed oxygen supply would be missing from an aeration system and the process would be slow and ineffective. When used properly by experienced professionals, aeration is one of our most important tools for preventing contamination in both surface and groundwater resources.
