DESIGN OF ONE BILLION GALLON PER DAY FINE SCREEN FACILITIES FOR THE ADVANCED WASTEWATER TREATMENT PLANT AT BLUE PLAINS
The District of Columbia Water and Sewer Authority's Advanced Wastewater Treatment Plant at Blue Plains, with a design average daily flow of 370 million gallon per day (mgd), and design peak flow of 1,076 mgd, currently utilizes coarse back clean/back return bar screens to screen the influent combined wastewater entering its two screening facilities. As part of an upgrade to the plant's headworks, the screening facilities will be retrofitted with 6-mm fine screens, screenings conveyance systems and two screenings loading stations. The screenings facilities upgrades will be constructed concurrently with upgrades to other major plant processes and installation of a plant-wide computer control system. This paper presents the design features that were incorporated to increase the reliability of the screenings removal process while minimizing maintenance requirements. Additional design features integrated to overcome the constraints of constructing within existing facilities that must be maintained in continuous operation, during several concurrent plant-wide upgrades, are also presented.
