Abstract
Historically, while alternative media materials have been employed over the years with varying degrees of success, the principal fine pore diffuser medium has been porous ceramic. In the early-to-mid 1970s, diffusers with plastic porous media were installed in secondary treatment plants in Europe, primarily in Finland and Sweden. In order to document operation and maintenance experience with porous plastic media diffusers, plants in Europe were visited to observe and report on their experiences. This report discusses these observations and reviews on-site, long-term operating and maintenance information. The conclusions, in general, were that plastic porous media diffusers were performing satisfactorily. The application and design of aeration basins with porous plastic media diffusers appeared to be similar to those for ceramic media diffusers.
