In the frozen food industry, Listeria is a particularly challenging bacteria as it does not go dormant at low temperatures. Bacterial counts also naturally increase throughout processing and packaging, which requires the operator to closely monitor bacterial levels and conduct complete shutdowns for CIP when necessary.

Headquartered in Mitchelstown, Co. Cork, Ireland, Dairygold’s production facility converts approximately 960 million liters (254 million gallons) of milk annually into top quality dairy products.

Clarksville, Virginia is a community home to many industries, such as candy manufacturer Russel-Stover. When the aerated lagoon – used to pre-treat wastewater – became overloaded, the town turned to Evoqua for solutions. While the effluent wastewater is hardly hazardous to your health, it is a very common problem for candy manufacturers as it contains a very high proportion of Biochemical Oxygen Demand (BOD) and Total Suspended Solids (TSS).

The protein processor’s existing 75 gpm boiler feed RO system was aging and struggling to meet peak demand for treated feedwater. It also lacked the capacity to support a planned plant expansion. To address this, the processor decided to install a new primary RO system and keep the legacy unit as a backup.

Lamb-Weston required a wastewater treatment solution at its plant in Taber, Alberta, Canada. Its potato processing wastewaters are characterized by high concentrations of biodegradable chemical oxygen demand (COD); suspended solids (SS); and fat, oil, and grease (FOG). This type of wastewater has proven to be an ideal candidate for anaerobic digestion.

Minimizing downtime while maintaining excellent plant sanitation and smooth operations are critical in processing fresh produce, such as tomatoes, which have a limited harvest season of approximately 100 days. With hundreds of tons of tomatoes arriving by truck daily, the plant needed every advantage to ensure cleanliness and keep it running like clockwork. As traditional biocides simply retard microbial growth, periodic plant sanitization shutdowns are required since these biocides do not completely kill the bacteria. In attempt to improve the overall efficiency and cleanliness of the plant....

CMS Energy needed to design and build a water treatment system to feed the turbines at the 155-megawatt Livingston Generating Station. The system had to withstand extreme cold and satisfy stringent environmental regulations. It also needed to meet a peaking station's intermittent need for reliable demineralized water.

High-purity water is essential for producing steam that will not scale turbine blades with silica, minerals, and other contaminants. A large power generating company in North America used a competitor's continuous electrodeionization (CEDI) system for that purpose.

Water quality is important not only in terms of safety but also has significant impact on the taste, product integrity, cleaning, and sanitation in the beverage industry. The water that has been contaminated with varieties of pathogenic bacteria can pose a threat not only to human and animal health, but also effects the product down time like the water used in the boilers and cooling towers...

Xcel Energy is a leading provider of electricity and natural gas to customers in the Midwestern US. As part of their expansion plans for the Comanche Station, a coal-fired electric generating station located in Pueblo, CO, Xcel Energy contacted Evoqua Water Technologies to explore cost effective solutions for their water treatment needs.
