Case Studies


Bacon Processing Plant In 2005, World Water Works, Inc. provided a Turnkey wastewater treatment system to a Midwestern bacon processing plant. Throughout the next several years, the system successfully maintained discharge compliance even as production continued to grow well beyond the designed capacity of the system. By 2017, the system at the plant was overloaded by more than 50%. Even though the system continued to maintain compliance, the plant proactively decided to expand its wastewater treatment facility to ensure they met their growing demand and maintained their standing as exemplary corporate citizens and environmental stewards.

Frozen Vegetable Supplier A frozen vegetable company was the premier supplier of individually quick-frozen onions, potatoes, roasted potatoes and vegetable blends to large food service companies. At their processing facility, a significant barrier to growth was faced due to an aging wastewater treatment system, which could not treat the anticipated flows that a plant expansion and production increase would generate. The lagoon based system would also periodically discharge an offensive odor during periods of high loading close to local houses and residence. With so many potential negatives tied directly to the existing wastewater treatment system, the company sought a solution that would address immediate and long-term business needs and further improve its longstanding record as responsible corporate citizens.

Railcar Bearing Manufacturer A manufacturer of railcar bearings, wheels, and axles needed a wastewater system upgrade to treat for oil, grease, suspended solids, and dissolved metals in a mix of process water and storm water runoff. The existing wastewater treatment system in place at the facility consisted of a small equalization tank, traditional clarifier and sand filter. Oils and greases want to float in the wastewater stream unless additional chemicals are added to cause them to sink; thus, the clarifier had a difficult time removing them from the water.

Ephrata Borough Authority WRRF Ephrata Borough Authority WRRF, located in the MidAtlantic region of the United States, has been battling chronic sludge settling issues since undergoing a BNR upgrade in 2011 to meet new permit limits. During the winter months, SVI values have reached as high as 300 mL/g. During the upgrade, the facility was converted from BOD and Ammonia removal to total nitrogen (TN) and total phosphorus (TP) removal.

Aluminum Casting Facility The aluminum casting facility of a producer of semifabricated aluminum products utilizes a closed-loop contact water system that supplies water to multiple DC casting pits. An existing induced air flotation (IAF) system was used for the reduction of TSS, NTU, oil and grease, followed by a cooling tower. The treated and cooled water was then reused in the caster as contact water. The IAF had a removal efficiency of approximately 40 percent, required regular maintenance attention, operated at 125 HP and used an excessive amount of chemistry, resulting in extraordinarily high operating costs.

Hopewell Water Renewal Hopewell Water Renewal (HWR) is a 50 MGD secondary wastewater treatment plant that treats the wastewater from local industries and domestic sources of the Hopewell, VA area. The plant began operating in 1977 and treats approximately 85% industrial waste. The facility achieves the treatment permit requirements for both BOD and TSS; however, treatment regulations have changed over the years and now require the removal of nutrients. HWR discharges effluent into Gravelly Run, a tributary of the James River and Chesapeake Bay Watershed.

Alchemist Brewery Alchemist Brewery is a microbrewery specializing in brewing, packaging and distributing its award-winning IPA beer, Heady Topper. An unprecedented following of the signature ale drove the need for a larger brewery and retail sales center. The brewery operates with a profound respect for environmental responsibility, so with a new facility in the horizon, there was opportunity to explore wastewater treatment system options that would allow them to minimize their impact on the town’s wastewater infrastructure.

Town of Ladysmith Ladysmith, BC is home to nearly 8,000 people on the western coast of Canada and has a history of coal mining, forestry, rail and marine industry. An existing wastewater treatment plant (WWTP) provided treatment to the town’s wastewater before discharging to the Ladysmith Harbor. The plant removed primarily particulate matter and suspended solids from the wastewater to be driven to a composting site. The existing system met some needs, but would not be able to achieve the future BOD and TSS effluent limits proposed to the town.
