title: Clogging and cleaning of fine-pore membrane diffusers.
abstract: Causes for the increase of the pressure loss of fine bubble diffusers made of elastomers were investigated. Methods are described for removing clogging material from membrane diffusers and/or attenuating or even avoiding the formation of clogging deposits. On the basis of some practical examples the procedure is discussed and obtained reductions of pressure losses are specified.
