The authors would like to thank City of Cleveland Division of Water and the Central Utah Water Conservancy District for providing staff, logistical support, and other assistance during pilot studies at their facilities in Spring and Summer of 2007. The City of Cleveland also provided a cash contribution of $20,000 to the project. The City of Boulder contributed similar staff time and logistical support during full-scale testing of DAF for SFBW treatment at one of their facilities. Two other utilities listed below (South Central Connecticut Regional Water Authority and Passaic Valley Water Commission) provided full-scale data from evaluations of plate or tube settlers for SFBW treatment at their facilities. Utility staff providing direction and support for these activities at each of these utilities are listed below:

  • City of Cleveland, Division of Water, Morgan Water Treatment Plant, Cleveland, OH – Maggie Rodgers, Tyrone Butler, Bob Mehota, and Dr. Edwin Guasp
  • Central Utah Water Conservancy District, Utah Valley Water Purification Plant, Orem, UT – David Hardy and Monica Hoyt
  • City of Boulder, Betasso Water Treatment Plant, Boulder, CO – Suzanne Givler and Randy Crittenden
  • South Central Connecticut Regional Water Authority, New Haven, CT
  • Passaic Valley Water Commission, Clifton, NJ
  • Santa Fe Irrigation District, Rancho Santa Fe , CA - Cor Shaffer
  • Aquarion Water Company, Monroe, CT

Infilco-Degremont (IDI), ITT WWW Leopold (Leopold), and Siemens Water Technologies provided equipment and staff, and other logistical support for pilot studies conducted during this project at the Cleveland, OH and Orem, UT locations listed above. These three manufacturers also provided staff time to provide information used to develop drawings and cost estimates for the tested high-rate processes. Pilot test reports were provided by I. Kruger, Inc. (Actiflo), Leopold (standard-rate DAF), and Infilco-Degremont (DensaDeg). Bench-scale membrane modules were provided by Koch Membrane Systems and CeraMem Corporation (purchased in April 2008 by Veolia Water Solutions, now part of HPD Membrane Technology Center).
