The objective of this white paper is the prediction of the wastewater treatment plant (WWTP) sludge production and subsequent power savings realized from operating the aerobic digesters via facultative digestion using technology from ENNIX⁽⁶⁾  INC. Development of the predictive spreadsheet permits one to demonstrate the power savings to potential users of the facultative digestion⁽⁶⁾ technology.

Until 2012, the Kaufman, TX, Wastewater Treatment Plant (WWTP) operated two separate aeration basins with mechanical surface aerators. As the plant’s equipment aged and required more frequent and expensive repairs and maintenance, the City of Kaufman followed its engineering firm’s recommendation to install a new, more efficient, fine bubble-diffused air system rather than simply replacing its old mixers with in-kind equipment.

Young’s Cove is a masterfully planned exceptional waterfront community situated in pristine Prince Edward County, on the shores of Lake Ontario. It has panoramic views, a children’s waterpark, miles of pathways, green spaces. It covers 7,000 feet of shoreline and fronts protected wetlands and preserves hundreds of acres of forest with birds and wildlife everywhere.

A pharmaceutical manufacturer was faced with major waste management concerns. They urgently needed a powerful shredding system capable of quickly and efficiently reducing bulky pharmaceutical rejects, packaging and literature to an unrecognizable condition. The company had recently purchased shredding equipment to replace older units, which were failing, but soon encountered unexpected problems. Pharmaceutical material passing through the carbon steel shredders often contained corrosive chemicals, which eventually eroded the units.

Read about a dewatering project that includes 57 kilometers of new railways with 34 kilometers of tunnels and 25 kilometers of high-speed lines. 

Small city selects full-featured and low maintenance UV treatment for its water reuse system that easily complies with demanding California Title 22 Regulations.

Business people love to talk about "disruption." They pride themselves on eating their competitors' lunch. Where their markets used to be about raving fans, now it's about inspiring craving fans, fueled by "hunger marketing" and the fear of missing out. There's a lot of dog-eat-dog philosophy...which is why it's important for companies to be willing to cannibalize their own technologies.

A growing number of wastewater treatment plant leaders are banking on newer technology to tap into previously unclaimed resources at their sites while addressing pressing needs such as increasing capacity and meeting more stringent treatment requirements. By looking at the process through a different lens and raising the bar when it comes to overall objectives, it is possible to shift facilities from being a cost center toward a revenue generator.

Built in the 1980s, Little Blue Valley Sewer District operates Atherton, which was designed to reduce the primary process chain to preliminary bar screening and aerated grit removal, while relying solely on secondary treatment performed in four, standalone 42-ft by 400-ft aeration/clarification basins. Read the full case study to learn how upgrading the activated sludge process with a combination of Xylem’s Flygt pumps and mixers created a solution for the city’s sewer district.

Handwheel or automated process valve? The worldwide trend is clearly moving towards automation, because it reduces energy and water consumption, especially rinsing water, and increases plant availability. Pneumatic automation of a fixed-bed filter is a good example of this.

A water purveyor was in urgent need of a chemically resistant flow instrumentation with a long life of service that allowed reliable and long-term stable dosing of the sodium hypochlorite solution.

QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.

Power plants and refineries around the world must manage and treat complex effluent waste streams from the Flue Gas Desulfurization (FGD) process. Flue gas is generated by the combustion process of fossil and fossil-derived fuels, such as coal, oils, and natural gas in power plants. Petrochemical refineries may generate flue gas from a number of different processes, including Catalytic Cracking, Steam Methane Reforming, and Heaters or Furnaces.

A water management company in Serbia used Panametrics' ultrasonic flow meter technology for stormwater management, ensuring reliable measurement and accuracy in challenging conditions. The technology allowed for live monitoring of water transfer and reduced the risk of flooding.

Industrial power plants or co-generation power plants utilize steam for industrial purposes other than power production.

Read about managing water discharge into a mixed water drainage system, electromagnetic flow measurement of water loads, and automated discharge control by way of a structure with overflow. 

Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry.

Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality.

The Moundsville Wastewater Treatment Plant in West Virginia chooses not to fix a broken blower unit, but rather to correct an outdated approach. The result is a savings of $50-60K a year in energy costs.

Water quality test strips have been around for decades. They are usually constructed from a porous media, including different types of paper, and undergo a color change when dipped into water containing the analyte of interest. These test strips have seen application in swimming pools, aquariums, hot tubs, remediation sites, and other commercial/environmental areas.
