F.B. Leopold has been awarded a contract to supply an ultrafiltration membrane system to Granbury, TX, located 40 miles southwest of Fort Worth.
Leopold designed and engineered the membrane system using results from extensive pilot plant studies at Lake Granbury, which is fed from the Brazos River. The Leopold 7.31 mgd ultrafiltration membrane system will treat lime softened feed water high in total dissolved solids, organics and suspended solids, providing a barrier against giardia, cryptosporidium and other waterborne pathogens.
The Lake Granbury Surface Water Treatment System (SWATS) is part of the Brazos River Authority.
Employing the HYDRAcap® membrane elements, manufactured by Hydranautics of Oceanside, CA, the Leopold UF membrane system with its barrier-style design uses hollow-fiber capillary membranes to remove a wide range of colloidal matter and pathogens.
The HYDRAcap based membrane system has been certified for greater than 99.99 percent (4-log) reduction of giardia and cryptosporidium, as well as 4-log reduction of viruses. It will reduce turbidity to levels typically less than 0.07 NTU, surpassing current and anticipated EPA standards.
For the Lake Granbury project, Leopold will supply a complete package including feed pumps, prefilters, membrane racks, backwash pumps, chemical feed systems, cleaning systems and controls and instrumentation.
The company designs and fabricates the system controls and integrates them with the plant's main control system. This ensures successful integration and operation with upstream and downstream processes. WW/
