EPA Researchers Explore Technology To Destroy PFAS

Per-and polyfluoroalkyl substances, otherwise known as PFAS, are a large group of human-made organic compounds with properties that make many of them toxic and persistent in the environment. PFAS have been manufactured and used since the 1940s in items such as fire-fighting foams, adhesives, cosmetics, paper products, and stain and water repellants. Until now, researchers have been unable to destroy PFAS in a way that has potential for larger scale use. 

DIMMINUTOR® Saves Monterey County Time, Money, And Manpower

The pump stations at Monterey Regional Water Pollution Control Agency (MRWPCA) were having a problem with their channel grinders. The twin-shaft, drum-style channel grinders were used in the ten pump stations in the region that feed into the main Monterey Regional plant.

Case Study: Real-time Continuous Nitrate Monitoring Provides A Window On Nutrient Loading In Lake Pontchartrain Louisiana's Lake Pontchartrain Basin lies at the mouth of the Mississippi Delta and squarely in the sights of water quality experts from around the world. The Lake Pontchartrain Basin is an esturarine system that has been significantly disturbed by the construction of the Mississippi River Gulf Outlet in the 1960s as well as agriculture, logging and development in the area. The lake's increasing salinity and shrinking wetlands have garnered significant attention, as has the nitrate-laden water rushing past the basin through the MRGO just below Pontchartrain's southern shore

Financing Stormwater Retrofits In Philadelphia And Beyond To reduce the environmental and public health threats posed by polluted stormwater and to comply with the Clean Water Act, cities nationwide are making significant investments to reduce stormwater runoff.

Using Digital Tools To Optimize Odor Control In Collection Systems

By utilizing digital tools, wastewater utilities can optimize their odor control program, which can reduce chemical usage, minimize compliance risks, and protect the community.

Reliability Delivered for Wayne County, MI CSO Facility

The Wayne County Downriver WWTF in Wyandotte, Michigan, is a CSO facility servicing 13 area communities with an average flow of 40 MGD. For wet weather and storm events, the plant is rated for 225 MGD—second only to Detroit in the state of Michigan. The plant is home to seven screens: four used during everyday flow, and an additional three accessed primarily during storm events.

FMCW Or ToF? Which Radar Level Technology Is Best For Tank Gauging In Custody Transfer Applications?

Measuring the level of tanks used to hold fluids for custody transfer can be expensive. This is not due to the cost of the measurement instrumentation, but to what inaccurate measurements can cost the company. Picking the right instrumentation for applications is important. Which radar level technology should you choose for tank gauging in custody transfer applications? Frequency Modulated Continuous Waveform (FMCW) or pulsed Time-of-Flight (ToF or PToF).

Targeting Need-Based Maintenance To Reduce Sewer Overflows

Whether addressing sanitary sewer overflows (SSOs), combined sewer overflows (CSOs), or storm sewer systems, the idea of advanced strategic insight is key to minimizing damage or public health risks caused by overflow events. Here is a look at how concentrating on the most at-risk areas first — with a focus on overflow prevention — can offer better control for wastewater utilities of all sizes, as it is doing for the city of Houston, TX.

Precision Accuracy Flow Measurement Through Ultra Mag Implementation

Explore why he Hach Ultra Mag is a fan favorite in numerous industries such as municipal water and wastewater, amongst others.

Expanded Use Of Split Seal Technology For Large Pumps And Agitators New advances in split mechanical seals have expanded its application for use in both water and wastewater systems. These systems move vast amounts of fluid through pipes and tanks. Water-based fluid systems comprise the largest fluid transport systems in the world with wastewater streams being the largest. While the systems’ designs can vary by region, most use centrifugal pumps to move fluid. Many of the centrifugal pumps are very large and difficult to assemble, so they have not typically been sealed by mechanical seals which require total equipment disassembly. However, split mechanical seals have advanced so that these pumps can now be sealed without equipment disassembly.
