Advanced perforation technology and a high strength polyurethane membrane are the secrets to the AEROSTRIP® fine pore diffusers high performance and long service life. Ovivo guarantees clean water transfer efficiencies of 8.5-10%/m (2.6-3.0% ft) side-water depth (SWD) in virtually all applications.
  • Highest proven oxygen transfer efficiency in the world
  • Longest service life on the market
  • Online maintenance with flexible diffuser operation
  • No dead zones

Aeration accounts for about 50% of a wastewater treatment plant’s energy bill and can consume significant maintenance resources to maintain performance. Reducing these operational costs while meeting today’s stringent permit limits is imperative for municipalities and industries today. AEROSTRIP® diffusers have been the leading technology to reduce operational costs and improve plant performance since 1996 with over 1,000 worldwide installations (over 60 in the United States).

  • Guaranteed standard oxygen transfer efficiency (SOTE) up to 10%/m (3%/ft) SWD
  • Membrane service life of 10 – 15+ years while maintaining peak perfromance
  • Perforation allows for intermittent operation and an automatic flex cleaning cycle
  • Evenly-spaced, floor mounted diffusers use the entire process volume

AEROSTRIP® diffusers use polyurethane membranes mounted on PVC or stainless steel bases. The membrane material offers about three times the strength of conventional EPDM membranes with less than one-third the thickness. The result is a long-lasting diffuser that retains its performance characteristics over many years.

AEROSTRIP diffusers can handle an operational flux range between 5 – 120 Nm3/m2/hr (0.3 – 7.1scfm/ft2), the widest range in the industry. In addition, AEROSTRIP diffusers are perfectly suited for intermittent operation without plugging or fouling of the pores. AEROSTRIP diffusers have been used extensively in SBRs, MBRs and industrial applications, as well as conventional activated sludge facilities.

Our floor mounted system makes for easy installation with many facilities opting to install the systems themselves. Upgrading their facilities with an AEROSTRIP system has allowed plant operators to save up to 50% on their energy bills, eliminate dead zones in their basins and eliminate much of their maintenance burden in favor of our online system.

The AEROSTRIP® diffusers are manufactured with a polyurethane membrane. Unlike EPDM membranes, polyurethane membranes have no softeners or plasticizers to leach into wastewater over time (the reason EPDM membranes require frequent replacement). AEROSTRIP diffuser membranes are proven to last 15+ years without replacement.

The advanced Austrian perforation technology and the thin membrane profile allow small bubbles to form without significant membrane fouling over time. The result is the highest guaranteed, proven, long-term oxygen transfer efficiency of any diffuser in the world. Perforation allows for a wide operational flux range of 5-120 Nm3/m2/hr (0.3-7.1 scfm/ft2) for every diffuser.

AEROSTRIP membranes are assembled onto either a stainless steel (“T” Type) or PVC (“Q” Type) base. Each diffuser is 15 or 18 cm (6 or 7”) wide and is made in lengths ranging from 0.5 m (1.6 ft) to 4.5 m (14.8 ft). Custom lengths are available. The heaviest diffuser we make is 12 kg (27 lbs). Every diffuser – yes, every individual diffuser – is pressure tested and operated while submerged in our test facility, and then hand-stamped with a unique serial number. ASCE oxygen transfer testing is also available in our 230 m3 (60,000 gallon) test tank.

AEROSTRIP diffusers are shipped to the site and installed according to the layout designed by Ovivo’s process engineers. Diffusers are typically mounted right on the floor, eliminating dead zones. Mounting bars may be used to mount multiple diffusers adjacent to each other to minimize penetrations into the concrete floor, to raise the diffusers, or for sloped floors. Stainless steel, HDPE tubing and PVC pipe is used for the air supply system. The strip shape allows for maximum flexibility in layouts as well as the possibility for high floor coverage.
