We provide engineered solutions to water and wastewater aeration problems including: evaluation of conditions, concept development, system design, product manufacturing, installation and service. We are committed to furnishing state-of-the-art and best available oxygen transfer and mixing technology from concept to installation and start-up.

Dew has installed equipment and aeration systems in over 150 companies. We have a long list of satisfied customers who benefit from our engineering, manufacturing and installation services.

Dew manufactures a number of high efficiency products and complete systems using the latest and best available oxygen transfer and mixing technologies.

Dewtex Grid

High efficiency coarse bubble floor grid systems for applications from mixed-limited to high rate aeration, including solids suspension.

Dewtex Float

Floating aeration systems for wet installations (drop-in designs) where no bottom contact is possible or desired, and when your aeration tank, basin or lagoon cannot be dewatered or removed from service.

Dewtex Aeration Systems

Custom designed aeration systems – blowers to diffusers – single source turnkey supply and extended warranty.

Dewtex Diffuser Membrane Kits

For retrofitting and membrane replacement applications.

Dewtex Tube

Static tube aerators for activated sludge, digester, equalization and other aeration and mixing applications.

Applications Engineering

Engineering studies are performed to select the proper Dew product or system to meet your aeration needs. Engineered solutions are developed for new installations and for replacement of existing diffuser elements.

Applications include:

  • Activated Sludge
  • Equalization
  • Pretreatment
  • Aerobic Digestion
  • Sludge Holding
  • SBR, SBBR & AS Processes
  • Chemical Oxidation
  • Mixing
  • Solids Suspension
  • De-stratification
  • Odor Control
  • Remediation


Custom Retrofit

Dew has developed a series of custom retrofit equipment and installation options. The solutions are tailored for each aeration upgrade whether done in the dry, or when the aeration system cannot be taken off line without interruption of the treatment process operation.

Where possible, reusable components of existing systems are retained and/or modified to reduce overall project cost. Also, existing systems can be supplemented with new Dew products to increase oxygen transfer capacity and mixing, and to improve overall oxygen transfer efficiency.

Whether you have diffused aeration or other types of aeration equipment, Dew can boost oxygen transfer and improve mixing by redesigning the aeration system and installing more efficient system.

Dry installations simplify the retrofit process and save even more money.
