FilmShear Technology: Maximizing Oxygen Transfer

FilmShear technology is a revolutionary approach to aeration design that optimizes the transfer of oxygen into water. It focuses on maximizing the surface area contact between air and water by generating thin, highly turbulent water films. These films are constantly broken and reformed, exposing a larger surface area to the incoming air bubbles, which ultimately results in:

  • Rapid and efficient oxygen transfer: FilmShear significantly enhances the rate at which oxygen is absorbed into the water.
  • Reduced energy consumption: The increased efficiency of oxygen transfer means less energy is required to achieve desired dissolved oxygen levels.
  • Improved water quality: Effective oxygen transfer plays a crucial role in eliminating unwanted substances and promoting a healthier aquatic environment.

How FilmShear Works:

FilmShear technology is implemented in diffuser systems through various techniques:

  • Turbulent flow generation: Diffusers are designed to create turbulent flow patterns that break the water surface into thin films.
  • Micro-bubble generation: Diffusers generate tiny air bubbles, maximizing the surface area contact with the water films.
  • Controlled air injection: Precise air injection ensures a continuous supply of bubbles and maintains the turbulent flow patterns.

The Impact of FilmShear:

FilmShear technology has a profound impact on the efficiency and effectiveness of aeration processes. It significantly increases oxygen transfer rates compared to traditional aeration methods, offering numerous benefits for environmental and water treatment applications.
