Getting started: how to find the right blower for your site

Before you look at the technical details of a solution, it's a good idea to go back to basics. Looking at the data plate of your existing units will give you some information, but not the full picture. What is the current capacity you need at your site? How do you compare blower performance data? With a few guidelines, you'll be able to spot the best offer in no time.

The true cost of your aeration air

There are many ways to look at the cost of aeration air. The number of running hours plays a vital role in your purchase decision. But cutting costs goes beyond looking at the price tag of a new blower installation. Discover our tips for a more sustainable process.

Applications

Diffused aeration

As bacteria can't survive without oxygen, a continuous oil-free air supply is important for the quality of your wastewater treatment process. The supply of wastewater can vary during the day so it's crucial that your blower installation can handle a variable air flow demand. We offer you both fixed speed blowers with a high turndown as well as energy efficient variable speed drive blowers.

Filter backwashing

Backwashing refers to pumping water backwards through the filter. Oil-free air prevents filter media from becoming dirty and unusable. It is a form of preventive maintenance so that the filter media can be reused.

Aerated lagoon

An aerated lagoon is a treatment pond that promotes biological oxidation of wastewaters. The diffused aeration system's efficiency has a direct impact on the quality and level of wastewater treatment that the lagoon achieves.

Activated sludge process

Air and microorganisms are used to biologically oxidize organic pollutants, producing waste sludge containing oxidized materials. The air in conventional activated sludge systems must be oil free to avoid contamination of the water.

Sequencing Batch Reactor (SBR)

SBRs are activated sludge processes designed to operate under non-steady state conditions. Operated in true batch mode with aeration and sludge settlement in the same basin. During the aeration phase, airflow is diffused in the tank. Thanks to fixed speed units the energy consumption is much lower, generating a competitive cost advantage.

Membrane bio-reactor (MBR) systems

A version of the conventional activated sludge system where solid and liquid separation is done by a membrane (micro- or ultrafiltration). Resulting in advantages for process control and product water quality but high energy consumption and intensive bio treatment process.
