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.

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.

LATEST INSIGHTS ON WASTEWATER
-
In areas with storm drains, the water can quickly overwhelm the drains, causing flooding hazards. For this reason, many towns have ordinances dictating how much ground can be covered with impermeable substrates.
-
Technology like advanced process control systems can streamline operations, create opportunities to lower costs and emissions, and ensure effluent quality meets the highest standards. Research also indicates that implementing an appropriate control strategy can help reduce N2O emissions.
-
Strategic flow monitoring helps wastewater utilities curb overflows, cut costs, and safeguard public health by turning accurate data into proactive action.
-
When seeking bids for a fair comparison, it’s important to evaluate the total cost of ownership.
-
Researchers have developed polyimide-based membranes for membrane distillation (MD) that overcome three persistent issues in membranes for water treatment and gas separations: the need for pore-forming chemicals that prevent recycling, performance degradation due to pore wetting and fouling, and the inherent trade-off between high water flux and selectivity.
