Abstract:

Screening is one of the most important components of a wastewater treatment facility and is essential to reduce downstream maintenance problems. To minimize downstream maintenance problems and improve aesthetics in downstream processes, there is a growing tendency to install screens with finer openings. In addition, some newer wastewater treatment processes, such as membrane bioreactors and biological aerated filters, require screen openings in the range of 3 mm or less.

There are a number of fine screen technologies available and selection of the most appropriate technology requires careful consideration of site specific objectives and constraints. When using fine screens, a careful review of the screenings handling systems is also required to minimize the overall volume of screenings, reduce captured fecal matter and reduce odours.
