This paper describes an application of microfiltration to convert a facility designed
to treat wastewater to a potable water treatment facility. The project was initiated
in order to reduce the utility's reliance on groundwater and provide a high quality
drinking water source. The project involved extensive process equipment
selection evaluations to determine the optimal configuration for water treatment.
The recommended process includes preliminary screening, dissolved air flotation
with enhanced coagulation, microscreens, pressurized microfiltration, granular
activated carbon, and disinfection with sodium hypochlorite. Major project
challenges included process selection and incorporating the proposed facilities
into the existing structure. Includes tables.
