Economical Aeration Systems

Diffusaire Ltd. – Founded in 2009 within the Kinrot Ventures incubator in Israel to commercialize its patent pending OTECH aeration technology. OTECH based products target global markets such as wastewater treatment plants (WWTP) and fish farms. Addressable markets are well over US$1.0 billion per year. The OTECH user benefits are 50% reduction in energy costs as well as an increased capacity/throughput, simplified maintenance and reduced CO2 emissions.

The Problem
Energy used by WWTP in the US alone is estimated by DOE at 1.5% of the total US electricity consumption. This translates to more than 3,000 MW of electricity, at an annual cost of about US$1.6 billion.  Aeration accounts for 50% of the energy cost in wastewater treatment plants.

 Solution & Technology
OTECH’s aeration system diffuses air into pumped liquids. The system extends contact time between bubbles and liquid by a factor >2 thus reducing the energy required for aeration by ~50%. An additional benefit of the OTECH system is a 20-40% reduction in installation costs, compared to current solutions.

Target Markets
New facilities as well as retrofits to existing facilities in the following target markets:

  • Municipal wastewater treatment plants
  • Industrial wastewater treatment plants
  • Intensive growth fish farms
  •  Potable water treatment plants

Initial commercial installations are expected in 2011, Diffusaire is signing up initial customers for pilot installations – please contact us if you are interested.
