Meeting lower discharge limits for cadmium to prevent fines
After new lower discharge limits for cadmium were introduced, a U.S. metal finishing facility providing aerospace and oil industry services reached out to Evoqua for help. Evoqua conducted treatability testing and filtration analysis, then implemented a selective media ion exchange solution using SCU vessels in a worker/polisher configuration to consistently meet strict ppb-level discharge requirements and restore compliance.

Meeting stringent phosphorus limits under a wide range of conditions
The Village of Waterbury Wastewater Treatment Plant (WWTP) is located on the Winooski River floodplain, which poses challenges from significant flooding during the spring runoff and storm seasons to strong algal blooms in late spring. During algal blooms, the plant encounters bright green lagoon effluent high in total suspended solids(TSS), resulting in treatment upsets and inconsistent permit compliance.

Mobile equipment reduces phosphorus in wastewater effluent
The city of Rosemount, Minnesota, was seeking treatment for phosphorus in the effluent discharge from the city's wastewater treatment plant. The customer's 0.75 MGD facility was permitted to discharge wastewater with a maximum average monthly total phosphorus level of 1.0 mg/l; however the effluent from the facility's newly installed disc filters was exceeding the NPDES permit limit.

Optimizing water meter accuracy: a data-driven approach to revenue recovery
This mid-sized utility located in Orange County, California has long been proactive in encouraging water conservation through regulations and outreach programs. Well over a decade ago, the utility became concerned with ongoing apparent water loss (water that is consumed but not properly measured, accounted or paid for) and the economic, social and environmental costs associated with this issue.

Sludge Handling in Perry, Oklahoma
The city needed to discharge sludge at two different rates–one rate for sludge returning to the headworks RAS and another rate for sending material to the sludge box. The system is designed to speed up dewatering biosolids as a replacement to the existing sand drying beds.

Phoenix improves arsenic concentration levels
Like many communities in the desert southwest, Phoenix, Arizona's water supply includes wells with arsenic concentrations exceeding 10 ppb. Long before the USEPA revised the arsenic rule from 50 parts per billion (ppb) to 10, the City of Phoenix began bench and pilot scale studies for arsenic removal options. Early investigations focused on well-known processes like activated alumina and ion exchange as well as less proven concepts such as coagulation-assisted microfiltration.
