Seneca Light & Water, serving the region of Oconee County in South Carolina, operates a 20 million gallons per day (MGD) Water Treatment facility that uses the 18,500-acre Lake Keowee as its source.\u00a0 The original plant started in March of 1969 as a 4 MGD facility and has advanced to the current rating with several upgrades.<\/p>\n
The Seneca water plant uses aluminum sulfate as a coagulant to lower the turbidity of the water.\u00a0 After a series of processes, the waste aluminum sulfate is dewatered so that as little water as possible is hauled away with the solids.\u00a0 Historically, a plate and frame press had been used.\u00a0 Although that equipment provided a reasonably dry product, about 24% solids, the equipment was only able to run in batch processes, was labor intensive, and was not a clean process to work with.<\/p>\n
In 2012, Seneca began a search to identify new dewatering techniques that could replace the aging plate and frame presses.\u00a0 Several pilot studies were completed, and Schwing Bioset was invited to run their screw press pilot in May of 2013.\u00a0 The pilot proved successful with a result of 27% solids, which was better than the performance of the existing plate and frame press, as well as the other screw press that had been tested.\u00a0 The Schwing Bioset equipment was chosen as the best value and the new FSP 0403 screw press was designed into the new dewatering building that was commissioned in September of 2015.<\/p>\n
The dewatered alum sludge is hauled to the nearby wastewater treatment plant and mixed with the dewatered Biosolids and then hauled jointly to the landfill.\u00a0 Now in normal production, the FSP 0403\u00a0screw press is producing 30% solids on average with a high of 34%, which is even better than the pilot results.\u00a0 This is all being done with a polymer dose of 5 pounds of active polymer per ton, which has proven to be very cost effective thus far.<\/p>\n
Seneca Light & Water ha cumplido su objetivo de reemplazar su tecnolog\u00eda de marco y placa envejecida por una prensa de tornillo de alta eficiencia energ\u00e9tica que permite un procesamiento continuo.<\/p>\n
La nueva instalaci\u00f3n en Seneca, Carolina del Sur, es la segunda puesta en marcha exitosa de una planta de agua de Schwing Bioset en las Carolinas este a\u00f1o.<\/p>\n
