Evoqua's Orbal System For Biological Nutrient Removal

Water is precious to the 8000 residents of this town in central Utah, as it is to so many similar places in the arid Intermountain West. Town history attributes Salem City's 19th-century founding to its location as a suitable spot for damming up a local spring to create a pond, which is still the centerpiece of the town. 

In order to meet future wastewater treatment requirements, Salem City would need to meet much lower limits for ammonia, phosphorus and possibly nitrogen, which discharges into the local watershed. In addition, with an expectation of significant population growth in the next few decades, Salem wanted to keep its options open for reusing treated water.
