Abilene and Wichita Falls, Texas, are expanding their water supply and treatment facilities
and face similar challenges: the lack of an available fresh water supply. Both communities
will be treating brackish surface water supplies for their expansion projects with treatment
product capacities in the 6-10 million-gallon-per-day (mgd) range. Planned treatment
includes dual-membrane processes: microfiltration (MF) or ultrafiltration (UF) for
suspended solids, and pathogen removal followed by nanofiltration (NF) or reverse osmosis
(RO) for dissolved solids reduction. The MF/UF systems at Abilene and Wichita Falls will
treat up to 8 mgd and 14 mgd, respectively. This paper discusses the preliminary feasibility
evaluation, pilot testing results, procurement of the full-scale MF/UF membrane equipment
using an evaluated proposal process, and design considerations for dual-membrane water
treatment plants. Includes tables.
