For each application in a wastewater treatment plant, we can provide you the most optimal solution. Our oil-free screw technology with variable speed drive for example, lowers your energy consumption by 30% on average compared to other technologies!
We offer a full range of blower and low-pressure technologies, developed and produced in house by our engineers. These are ideal for wastewater treatment applications, given the lower noise and vibration levels or airflow regulation that are combined with a variable speed drive. Our products can be tailored to match all your needs!

The DZS dry claw blower is an ideal solution for applications that require a low air flow and pressure. 30-200 cfm | 7.3-33.3 psig
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.
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.
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.
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.
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.
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.
