Time-Tested Technology: 25 Years of Trickling Filter Media Success

The Bissell Point Wastewater Treatment Plant is the largest wastewater treatment facility in Missouri with an average flow rate of 123 MGD. In the mid-1980s, the facility expanded to provide secondary treatment. The goal of the upgrade was to select a reliable process that would achieve high-rate BOD removal.

Rental Blowers Provide Timely Solutions For Temporary Aeration Concerns

With a continuous flow of air required to maintain dissolved oxygen (DO) levels, the last thing a wastewater treatment plant (WWTP) operator wants is to come up short of the volume needed to sustain good microbial growth. With today’s ready availability of high-efficiency rental blowers, losing blowers to unplanned downtime or being unable to test new aeration systems before commissioning are no longer the threats they once were.

The Importance Of pH Measurement During Industrial Treatment

Nearly every industry requires water and wastewater treatment to some degree. From food and beverage to pulp and paper operations, influent and effluent must meet certain conditions to adhere to regulatory and/or performance requirements, and water used during the process must conform as well.

Here's To Microbrews And POTWs

As local breweries grow in popularity, their initial focus on hand-crafted recipes can quickly shift to business realities such as the costs and logistics of process wastewater treatment. Publicly owned treatment works (POTWs), brewery owners, and consulting engineers all have roles to play in making that trajectory smoother for up-and-coming craft and microbrewers.

Fluence's MABR For Wastewater Treatment features Passive Aeration And Saves Up To 90% On Energy Costs

The Bordeaux region of St. Thomas had a pressing need for a wastewater treatment plant that produces high effluent quality. Its existing plant was old and did not meet regulation nor industry standards. Fluence, together with its partner SD&C Inc., built an MABR-based wastewater treatment plant from the ground up, utilizing whatever existing pieces of equipment could be used from the old plant.
