Wastewater aeration Brisbane involves adding air directly to wastewater to allow aerobic bio-degradation of the pollutants in the wastewater. Aeration of wastewater is an essential component of wastewater treatment. The main aeration benefit is that it is a natural method of removing pollutants from wastewater. Using chemicals is not safe because they react with other systems and they can be harmful when used in large amounts. On the other hand, the aeration process uses microorganisms within the wastewater to degrade the contaminants.

Types of aeration systems

There are different types of aeration systems that you need to know. We have three essential types of aeration systems – a spray aerator, a diffused bubble aerator and a packed tower aerator. It is crucial to understand the difference between all these types of aerators because each system functions differently and comes with its benefits.

Packed tower aeration systems

This type of aerator is a system that has a tower filled with packing material. The towers can be up to about ten feet tall and this means that you will need enough space in your plant if you want to use these aeration systems. The packing material that is contained inside the packed tower can be between half an inch and three inches in size. It can also consist of small pieces of ceramic and plastic. Whilst different materials can be used in the packed tower aerator system there is no benefit toward using either material over the other.

It has been found that smaller materials allow better efficiency but they also increase energy costs for the water solutions company. When it comes to using this system then the wastewater falls from the up-most section of the tower whilst air is continuously blown upwards into the water for aeration. The contaminants in the wastewater will then transfer the air from the water before they can be moved outside.

Diffused bubble aeration systems

These types of aeration systems are likely to be the most popular systems that consist of a lot of chambers and a diffuser that air is blown through. The diffuser creates small bubbles that flow through the chambers. The bubbles carry contaminants and chemicals that you are trying to remove.

After the contaminants flow through the vent system, they are sent into the outside air. When there is a high number of chambers in the diffused bubble aerator, the system becomes more efficient. On the other hand, a small number of aerators are usually outfitted with a switch that trips an alarm in case the chambers are close to flooding. Whilst there are several different types of these aerators, each of them operates similarly.

Spray aerators

These are common types of wastewater aeration Brisbane systems and they are designed to remove small amounts of volatile pollutants. When using this system, water enters at the top of the system before it can materialise from the spray heads in a fine mist. The treated water is then collected within a tank that is situated under the head of the spray.
