Choosing aeration

Selecting the right aerator for you is significant to make sure you’re getting the best out of your water treatment system. Unfortunately, there is no ‘one size fits all’ solution, so selection will come down to two main factors: job application and standard aeration efficiency (SAE).

Job application should be determined first so that the proper type of aeration system can be selected. It can be confusing deciding which aerator best fits your situation, so examples have been provided below:

EXAMPLE

SITUATION

Medium to large ponds where it is important to distribute oxygenated water away from the aerator

Multiple tanks and ponds, blower to be centralised and the compressed air to be directed where needed

Destratification will solve the bottom oxygen problem

Small volume of water where stocking density is high

Emergencies to raise oxygen level in small area

SYSTEM

Water-moving and paddle wheel types

Diffused aeration

Few Air Diffusers

Surface aerator

Once you have selected an aeration system from your job application, the standard aeration efficiency should then be considered to further narrow your choice to get the exact model that is best for you. The SAE can be calculated by measuring the aerator’s oxygen transfer and the amount of energy used per horsepower, per hour, under standard conditions. The higher the SAW, the high the oxygen transfer and hence efficiency.

Of course, the number of different situations is endless and the smallest difference could alter the aeration system that fits your needs. In terms of installation, our team is more than happy to come out and install your system correctly and efficiently with no hassle. However, should you prefer to install the system yourself, we can give you expert advice and assistance on doing so.
