This session will focus on the design and operation of mechanical screens and associated screenings handling equipment to effectively remove flushable wipes and rags from the raw wastewater stream. We will review various mechanical screening technologies commonly used in the wastewater industry, and compare their design features and O&M requirements.
Understand the design features and O&M requirements of various mechanical screen technologies.
Understand the design features and O&M requirements of screenings conveyors and screenings washer/compactors.
Understand the impacts of mechanical screen selection have on treatment plant hydraulics and collection system hydraulics just upstream of the headworks.
