This paper begins by providing a brief overview of the Dublin Road Water Plant (DRWP) located in Columbus, Ohio. Project objectives were to
upgrade the DRWP capacity from 65 to 90 mgd,
meet existing and proposed regulations for
nitrate,
atrazine, and disinfection byproduct
control and total organic carbon (TOC),
consider innovative processes, and to
minimize capital and operations and
maintenance costs. Project challenges included
expanding the plant within current site constraints,
maximizing the use of existing facilities,
maintaining plant capacity during construction, and
considering Ohio Environmental Protection Agency (OEPA) approvability. Upgrade and expansion analysis included a three-phased approach of
condition assessment,
feasibility study and
pilot testing. Pilot testing included
three alternatives: Dissolved Air Flotation Clarification, Solids Contact Softening,
Recarbonation, Filtration, Sidestream Reverse Osmosis; Enhanced Microsand Clarification, Filtration, Reverse Osmosis; and, Immersed Ultrafiltration and Reverse Osmosis. Includes 4 references, figures.
