Parkson recently had a very successful pilot test at the facility of a bio-feedstock supplier of waste products turned into fuel. The Rotoshear® unit, equipped with a .060” wedgewire screen, successfully removes solids directly from Industrial Waste Hauling trucks to recover grease. Screening this material before it enters the receiving station allows the facility to focus on proper treatment of the industrial wastewater rather than the expensive downtime to drain and clean their receiving pond.
In the discussion about limited resources and energy saving in sewage treatment plants innovative sewage treatment methods are increasingly becoming a focal point. In Germany, there are about 1,200 sewage treatment plants which are designed for 10,000 to 50,000 PE, about one third of them have a sludge digester. Thus, there is a potential of about 800 sewage treatment plants that remains for a change from aerobic sludge stabilisation to processes with anaerobic sludge stabilization.
City staff were looking for an idea to remedy the logistical issues in the Tarpon Springs Wastewater Treatment Plant located in Pinellas County and known for being a small Greek community on Florida’s Gulf Coast.
Despite the destruction of Hurricane Harvey in August 2017, Duperon® wastewater screening systems in the cities of Cuero and Refugio, Texas – approximately 150 miles southwest of Houston – were virtually unaffected by the storm. Duperon’s FlexRake® bar screens, installed at both locations as well as dozens of other sites in and around Houston, remove objects like rags, paper, plastics, and metals to prevent damage and clogging of downstream treatment equipment. Both communities found essentially no damage to their wastewater screening equipment.
Spent hops and general brewery wastewater are natural by-products of the beer-making process and must be reused or disposed of accordingly. Some brewers are charged substantial fines for dumping high-solids wastewater into the city sewer system. With Parkson Rotostrainers, over 90% of the Biological Oxygen Demand (BOD) of wastewater can be filtered out, greatly reducing the city sewer charges. Many breweries can even sell much of the spent grain and other captured solids to local farms as livestock feed, thereby profiting on an otherwise ‘waste’ product.
Scum is not a substance that anyone in a wastewater treatment plants wants to deal with. Scum, the greasy substance that floats to the surface of clarifiers, gets nastier as it accumulates. Some smaller wastewater treatment plants mix their scum back into other processing streams while other larger plants treat their scum separately. The City of Fort Worth takes a unique approach in managing its scum and now turns what was once a liability into an asset.
The City of Dixon, Illinois, located 100 miles west of Chicago, went on-line with an upgraded 4.5 MGD wastewater treatment plant in February 2002.
Oostburg’s Black River Falls facility is a lean operation with limitations in space for screening technology and in the staff resources available to manage, maintain and report on the Village’s processes. Even though space was limited, Oostburg knew that putting a headworks screening solution in place would improve their operational efficiency. Oostburg found the perfect solution using the Huber Technology RoK4 confined space vertical screen.
In 1997, back before text messaging and cell phones, Duperon Corporation installed the FlexRake® FP Full Penetration Coarse Bar Screen into its first wastewater treatment plant at the City of Adrian, Michigan. The same equipment is in operation today, with all of its original components, with the exception of a motor/drive head bearing replacement.
Billerica, Massachusetts embodies an ideal American suburb – picturesque streets, quaint houses, inviting storefronts and a central city square perfect for socializing with fellow neighbors and visitors. Located just 50 minutes north of Boston, Billerica is also a prime spot for young families who want the convenience of a close-by city with the atmosphere of a restful community.
Cherokee County, GA, conducted an extensive on-site pilot evaluation of several available process options and technologies, including various plate settler designs. Read the full case study to learn how enhanced nutrient removal (ENR) integrated design continues to deliver water quality of <0.1 mg/L Ammonia, <0.07 mg/L Phosphorus and <0.5 NTU. Not only does the WWTP consistently meet EPA direct discharge limits on BOD, Total Nitrogen, Phosphorus and Turbidity, but these final effluent values readily exceed surface water discharge permits levels.
The Coors Brewery facility in Golden, Colorado utilizes the Duperon® FlexRake® FPFS to treat the process influent resulting from their brewing operation.
