Meurer Research Inc.’s inclined plate settlers and hoseless cable-vac sludge collectors are being installed to replace aging equipment, improve effluent quality and enhance solids removal at the Richmond, Virginia, water treatment plant. The MRI system is designed for a maximum peak flow of 140 mgd. To retrofit the four sedimentation basins, MRI equipment is being installed in one basin per year over a four-year period. The phased approach enables the Richmond plant — one of the largest water producers in Virginia — to be upgraded without interrupting operations. Retrofitting of the second basin will be completed this year. Installation in the first basin was completed in 2015. The final two basins will be completed in 2017 and 2018.
