Three UV systems were pilot tested at the South Valley Water Reclamation Facility (SVWRF) in Salt Lake City, Utah: two low-pressure low-intensity systems (one with horizontal lamp orientation, the other with vertical lamp orientation), and one low-pressure highintensity system. Wastewater effluent at SVWRF is high quality (75 to 85% UVT) but very hard (averaged 309 mg/1 as CaCO3 during the pilot study). Therefore, the pilot study was primarily structured as a fouling study, and testing objectives included estimation of fouling rate, and comparison of performance and operational characteristics for the three pilot units. It also evaluated the effectiveness of the LPHI pilot unit automatic cleaning system (which is mechanical only) under these hard water conditions. Pilot testing occurred over a four-month period during the summer of 2000.

Results indicated a small amount of fouling from mineral deposits. Significant biological fouling occurred on UV systems without operating automatic cleaning mechanisms, when the lamps were off for more than one week.
