Waste water treatment compressed air

Sewage and Wastewater Treatment

Oil-free air blower solutions for each Sewage and Wastewater Treatment application both industrial and municipal. We offer clean air technology, with high energy efficiency and low total cost of ownership.

 

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

Up to 70% of the energy consumption in a sewage or wastewater treatment plant is used by air blowers. So, keeping energy costs down is key to keeping total operational costs low. To ensure we keep your operational costs down, we designed the most efficient and reliable machines on the market. This will ensure a faster return on investment!

Easy integration

Thinking about the installation of your air blowers might seem like something you do after you've purchased them. Thinking ahead will save you from unexpected costs. For instance, not all blowers are offered as complete packages. Making sure you have a complete package will ensure that everything you'll need for operation is included in your purchase. What are the hidden costs? What should be included before your blowers can be deployed into the treatment process?

Never run out of air

Minimizing emissions & breakdowns

Compressed air is an integral part of the wastewater treatment process. The first step towards a more reliable process is choosing the quality equipment that fits your needs. It's key to stay ahead of new governmental guidelines and regulations. The increasingly strict rules require your process to emit a minimal amount of carbon and the water to contain a minimal level of pollutants after treatment.

Optimal aeration control

Designing your aeration control system affects the efficiency of your process. More control means more knowledge and fewer chances of a complete breakdown. The more control you want, the more data you'll need. Traditional blower setups such as cascade sequences or unit control through gauges only allow simple measuring and control. Discover our tips and tricks to get more control over your system.

Minimal maintenance

Correctly maintaining your aeration installation ensures a smooth treatment process. Preventive maintenance is a great way toward a healthy installation. But taking the next step toward predictive maintenance will pay off in the long run. Discover how you can extend traditional service intervals and avoid those unwanted breakdowns.

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 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.
