After receiving an NPDES operating permit that required the plant to remove total nitrogen (TN) to 5 mg/L from May through October the Narragansett Bay Commission chose AnoxKaldnes Hybas™ (Hybrid Biofilm Activated Sludge), an integrated fixed film activated sludge (IFAS) process, as their solution.
Two municipalities were faced with odor issues and required corrosion prevention in their collection systems. Monitoring in the sewer lines indicated peak H2S atmospheric concentrations of 300-500 ppm. Both clients desired H2S < 20 mg/L to prevent corrosion and preferably lower to prevent H2S odor.
The Picnic Point Wastewater Treatment Facility is located in Edmonds, WA and is operated by the Alderwood Water and Wastewater District out of Lynnwood, WA. The BioCon® dryer has been operational since 2013. The plant has a design flow of 4 MGD, expandable to 6 MGD.
The city installed a 3 to 6 MGD desalination facility for the production of drinking water and must overcome significant challenges as outlined in their 40-year Water Development Plan.
The James River Treatment Plant, owned by Hampton Roads Sanitation District, has upgraded to meet the Total Nitrogen mass load in order to produce an annual average concentration of 10 mg/l.
"The carbon footprint analysis was conducted considering both the embodied carbon for the construction and implementation of the alternatives as well as the operational equivalent CO2 emissions for power, methan (CH4) and N2O."
A carbon footprint analysis was performed comparing tertiary filtration technologies: the Kruger Hydrotech Discfilter and conventional sand filters. The Hydrotech Discfilter employs woven cloth filter elements installed vertically on multiple discs, supplying a large filter area with a small footprint.
Fairplay Sanitation District - Meeting ammonia permit limits in a small footprint at cold temperatures with ease of operation
The Fairplay Sanitation District was challenged in meeting their ammonia permit limits and wanted a process that would produce a stable effluent in a small footprint. Influent water temperatures were regularly recorded in between 6°C and 10°C. Due to these cold temperatures, nitrification was not being achieved on a consistent basis.

The City of Palm Coast, located on the east coast of Florida, expanded their existing Wastewater Treatment Plant (WWTP) to increase capacity to 6.83 MGD due to population growth, as well as add the production of reclaimed reuse water for use within the City.
