Mixers Clear FOG And Reduce Operating Costs By More Than 80%

The Cypress Creek WWTP in Florence, AL, uses an extended aeration activated sludge process with a design capacity of 20 million gallons per day (MGD). Cypress Creek serves mostly residential customers, but about 15 percent of its influent comes from industrial sources, and their discharge to the plant contains large amounts of fats, oils, and grease (FOG).

Addressing Fouling Challenges In Water Treatment With RO Membrane

Reverse osmosis (RO) membranes are widely used in potable water, wastewater, and industrial applications. However, a major issue in the application of RO membrane technology for desalination and wastewater reclamation is membrane fouling. It limits operating flux, decreases water production, and increases power consumption. Membrane fouling also increases the need for RO plants to perform periodical membrane CIP procedure. These problems decrease process efficiency, increase operation cost, and raise environmental issues related to the CIP solutions disposal.

WTP Chooses A-758 Plus™ Lime Slaker Systems To Replace Existing Systems

The Albert R. Davis Water Treatment Plant (WTP) in Austin, Texas, is one of three water treatment plants supplying drinking water to the greater Austin metropolitan area. The plant was built in 1954 and has had multiple upgrades over the years, increasing its capacity to 118 million gallons per day (MGD).

A Fairy Tale Ending At A Pump Station

When the Otay River Pump Station had a floating blanket of grease problem, they turned to the Vaughan Chopper Pump to help eliminate it — while also being a cost-effective solution.

Award-Winning Design Helps WWTP Protect Chesapeake Bay Watershed

Arlington County’s Water Pollution Control Plant (WPCP) in South Arlington, VA, is located on 35 acres of land squeezed into a commercial/residential neighborhood less than a mile west of Ronald Reagan Washington National Airport. The facility treats flows from nearly all of Arlington. In addition, nearly 20 percent of the plant’s flow comes from neighboring localities such as Alexandria, Fairfax County, and Falls Church. Effluent from the plant is discharged into Four Mile Run to the south, which feeds into the Potomac River and, ultimately, the Chesapeake Bay.

Small Footprint, Big Results: California Casino Wins With MBR

Quechan Casino Resort, a gaming facility located on Native American owned land in Winterhaven, California, began its wastewater treatment operations in January 2009.

Stormwater Wetland Reduces Sewer Overflow By 84 Percent

Through hydraulic computer modeling, MWH Global helped alleviate stormwater flooding in Cambridge, M.A., by creating the Alewife Reservation Stormwater Wetland to enhance water quality and provide recreational benefits to the community.

White Paper: Performance Of Floating Horizontal Aerators In Aerated Lagoons And Oxidation Ditches When selecting aeration equipment to use for a specific application, issues to address include reliability, serviceability, capital cost, system appurtenances, and cost of operation and maintenance. Another important consideration is oxygen transfer rate (OTR). Horizontal floating aerators have relatively high transfer rates and have been used successfully in aerated lagoons and oxidation ditches. Using equipment with high OTR values reduces the horsepower input that is required and subsequently lowers capital cost and O&M costs. Mixing of wastewater in lagoons and oxidation ditches is also important to maintain solids in suspension

Overcoming Inconsistencies In Digester Gas Measurement

Thermal mass flow meters do a good job of measuring gas flows in water treatment and wastewater treatment applications. Measuring digester gases, which can contain moisture ranging from vapor to droplets, however, makes the job a bit tougher for all gas flow measurement technologies. Identifying the right solutions to deliver accurate, repeatable and reliable readings without having to reengineer the piping system becomes much easier and more economical by following these helpful guidelines.

Analyzing Total Organic Carbon In Sea Water

The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.

Lab Gas Sub-Metering Accuracy Improves With Thermal Flow Meters To Save Money

Facility administrators will find the advanced ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) helps them improve the accuracy of specialty gas point of use and sub-metering operations to achieve accurate billing in their labs for better cost tracking and control.

Removal Of PFCs With Activated Carbon

In recent years, various perflorinated chemicals (PFCs) have come under increasing scrutiny due to their presence in the environment, in animals, and in human blood samples. There are two major classes of PFCs: perfluoroalkyl sulfonates such as perfluorooctanesulfonic acid (PFOS) and long chain perfluoroalkyl carboxylates such as perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA).

A Non-Intrusive Solution For Measuring Wastewater Flow In A WWTP's Iron Pipes

A municipal association needed to understand if wastewater was being equally distributed across two cast iron pipes within its wastewater treatment plant. Learn how clamp-on ultrasonic measurement helped successfully measure the flow.
