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.

Wastewater Treatment Applications
Membrane Bioreactors
Membrane bioreactors feature an ultrafine membrane filter installed at the discharge end of a standard aeration basin. Pumps installed on the membrane filters create a slight vacuum and pull the effluent through the membrane. The ultrafine holes in the membrane do not allow the biological microbes to pass through the membrane
Efficiency and reliability is key for low cost of ownership
Up to 70% of the energy consumption in a wastewater treatment plant is used for aeration. Additionally, five to ten times the purchase price of a blower will be spent on the energy consumption of the units. Keeping energy costs down is key to keep total operational costs low. We are committed to keeping your operational costs down by offering one of the most efficient and reliable machines on the market, making your investment profitable as soon as possible.
Reducing the environmental impact of wastewater treatment
Efficient water management becomes increasingly important due to scarce availability of resources and the rising financial pressure. When counting on an air supply to keep the bacteria alive during the treatment process oil contamination is not desirable. That is why our products are oil-free, helping you, in addition to reducing your energy consumption, to further reduce your impact on the environment.
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 airflow 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. It's also worth noting that there are two types of aerators: surface aerators and diffused aerators. The latter uses almost half the energy of surface aerators.
Activated Sludge Process
Air and microorganisms are used to biologically oxidize organic pollutants, producing waste sludge containing oxidized materials; in simpler terms, the suspended solids are separated from wastewater via a sedimentation process. 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. These are 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
MBR is a version of the conventional activated sludge system where the solid and liquid separation is completed via a membrane (micro- or ultrafiltration). This results in advantages for process control and product water quality but high energy consumption and intensive bio-treatment process. Another benefit of MBR is that this method can be scaled to fit any size wastewater treatment plant.
Moving Bed Biofilm Reactor (MBBR)
Biofilm carriers (small plastic balls) are utilized to breakdown any pollutants in the wastewater, and the carriers are dispersed throughout the basic via a diffuser grid. MBBR can be scaled to fit any wastewater treatment facility.
Anaerobic Digestion
This process treats the sludge and other waste created during the wastewater treatment process. Microorganisms break down this waste into CO2, methane, ammonia, and other gases; these biogases are treated via filters prior to being injected into a generator; they can also be removed and flared to reduce greenhouse gas emissions.

Montville Wastewater Treatment Plant
The Montville Water Pollution Control Facility uses six Sequencing Batch Reactors (SBRs) to treat their wastewater. The influent flows have significantly higher loading than average due to industrial users from a paper plant and also a nearby casino due to those high loads. They need much more air than your average wastewater treatment plant. Atlas Copco met with Superintendent Derek Albertson about to discuss the application and why Atlas Copco’s ZB VSD+ blower was the perfect the needs of the facility.

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.
