GUTHRIE, Ky., Jan. 8, 2001 — The Logan-Todd Regional Water Commission selected USFilter to provide the first micro-filtration system in Kentucky for its new $55 million water treatment expansion.
The expansion is part of a water treatment regionalization of 12 water systems in the rural areas of Logan, Todd, and part of Christian counties in Kentucky.
The water source, the Cumberland River located 15 miles from the intended plant, required careful consideration of technology since it has a wide range of quality issues, including seasonal high turbidity. The $3.8 million state-of-the-art, Memcor� CMF (continuous micro- filtration) system was chosen because of its ability to guarantee pathogen removal and meet the stringent regulations.
"Building a new plant gave us a unique opportunity to evaluate all filtration options. Membrane filtration offered many advantages over more conventional systems that it came out the clear winner," said Mike McGhee, P.E., lead project engineer of McGhee Engineering, Inc.
Since the CMF system was the first micro-filtration installation in Kentucky, the Kentucky Division of Water required approval. To ensure the final system sizing and design would accommodate the water quality standards, a five-month pilot was performed to simulate a wide range of operating conditions using full-scale membrane modules. The Memcor� CMF system automatically detects and reports irregularities in performance, ensuring a four-log minimum removal of pathogen-sized particles.
The pilot unit included the polyvinylidenediflouride (PVdF) membrane material, which allows the use of chlorine as one of the treatment chemicals. Along with the pressure decay test (PDT), the trial on the PVdF membrane proved its durability, cleaning ability and performance to produce safer, better quality water.
The USFilter partners for this project include the design team of McGhee Engineering, Inc., Guthrie, Ky., PEH Engineers/Strand Associates, Louisville, Ky. & Madison, Wis. USFilter representatives who are participating in this project include Energenecs, Inc., Cedarsburg, Wis. and The Henry P. Thompson Co., Cincinnati, Ohio.
