High Intensity Air Injection Spargers - Outotec

Sparger technology has developed significantly since the introduction of these first simple pipe systems. Although the first sparger design with automatic protection in case of air-supply failure was developed in the 1970s, this system suffered problems with wear. The concept of automatic closing was further developed in the 1990s.
