Abstract:

Wastewater treatment plant personnel and consulting engineers have a common desire: Select a grit removal system to remove as much grit as possible from their operations. No comprehensive study has been made to date analyzing what sizes of grit is predominate in the various regions across the USA and which grit removal system is best suited to remove the majority of grit. Grit composition information in conjunction with required minimum velocities in the plant influent lines is critical and must be known in an effort to make informed decisions. This valuable information will be used for both headworks design as well as consideration given to which type of grit removal system removes the majority of grit, and on what sizes of grit are being removed.
