Platte River Power Authority Restores Cooling Reservoir, Reducing Maintenance Costs And Improving Wildlife Habitat

Top-performing coal-fired power plant finds that SolarBee^® solar-powered mixers combat blue-green algae in 500-acre reservoir without the need for chemicals or mechanical aeration.

Indiana Wastewater Monitoring Program: Sampling Community Sewersheds For SARS-CoV-2

A community wastewater system can provide valuable information about public health conditions in an anonymous and rapidly accessible manner. One area where this is especially powerful is infectious diseases, which are shed into wastewater systems. In response to the global COVID-19 pandemic, the scientific community has rapidly mobilized to determine if wastewater monitoring for SARS-CoV-2, the virus that causes COVID-19, could be detected and quantified in wastewater streams and sludge.

Peaking Factors And Hydraulics In Wastewater Screen Sizing

Dealing with fine particulate matter, nutrients, and pathogens is essential for wastewater treatment plants (WWTPs) striving to meet Clean Water Act (CWA) effluent standards. Before that stage, however, come important considerations about removing larger debris that can clog pumps, overload clarifiers, or disrupt other downstream processes.

Use Of Low Voltage Conductivity To Conduct A 10km Inspection Of Legacy Cured-In-Place Pipe For A Leak Assessment Project

In 2017, the Institute of Underground Infrastructure (IKT), Gelsenkirchen, Germany, utilized low voltage conductivity to test a variety of trenchless Cured-In-Place Pipe (CIPP) short-liners to locate and quantify leaks, several of which were utilized in a multi-million rehabilitation project in Kansas City, Missouri (USA).

Acoustic Inspection As A Solution For Rural Water

To improve efficiency, a Virginia utility adopted acoustic inspection technology (SL-RAT) in 2018, enabling a shift to condition-based maintenance.

Case Study: Steel Processor Wastewater Recycle

The reuse of industrial wastewater is becoming increasingly common because of water shortages, environmental necessities, economic incentives, government mandates, and societal desires. By David Christophersen, Technical Support Manager, Veolia Water Technologies

Easy And Trouble-Free Self Priming Centrifugal Pump Adjustments

Most manufacturers employ a semi-open impellers in their self priming centrifugal sewage and trash pump designs. While other types of impellers, (enclosed, open or recessed), are sometimes used, this type of impeller has a proven field record for clog resistance and high efficiency. By Kevin Clemons

Turbo Blowers Evolving For Large Sewage Plant Efficiency

Until recently, multi-stage centrifugal blowers and gear-driven single-stage turbo blowers have dominated larger wastewater treatment plant (WWTP) operations. Turbo blowers in the 50 hp to 300 hp range have historically been popular for their low total lifecycle cost in mid-range WWTP applications (from 1 MGD to 20 MGD).

Is ORP Really Your Best Option For Dechlorination Measurement?

In this application note, explore considerations for achieving more reliable accuracy when quantifying dechlorination results for applications ranging from RO membrane protection to wastewater discharge compliance.

Aerated Biological Nitrogen Removal

Excess ammonia in receiving waters causes algal blooms that decrease oxygen levels. For this reason, many wastewater treatment plants (WWTPs) must limit ammonia in discharge. Mike Rousey, Hach Company

VFD Energy Savings For Pumping Applications

In the early days of variable frequency drive (VFD) technology, the typical application was in process control for manufacturing synthetic fiber, steel bars, and aluminum foil.

Best Practices In Moist And Wet Gas Flow

The Wet Gas MASSter sensor is for use in applications that have a high level of moisture or condensation present in the gas flow stream that cannot otherwise be removed.

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.

LLT100 Laser Level Measurement In Water And Wastewater

In the water and wastewater market segment, the LLT100 laser level transmitter provides an efficient way to measure levels of liquids.

Instruments For Environmental Applications

Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality.

Wet Weather Treatment Using AquaStorm® Cloth Media Filtration

This application note from Aqua-Aerobic Systems highlights the effectiveness of the AquaStorm® Cloth Media Filter as a flexible, compact, and highly efficient solution for Combined Sewer Overflow (CSO) and Sanitary Sewer Overflow (SSO) events.

Determination Of Pesticide Residues In Honey, By An Automated QuEChERS Solution

The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.

Primary Wastewater Treatment: Influent Monitoring

The raw sewage entering a wastewater treatment plant comes from a variety of sources. In addition to effluent from domestic users, effluent from industrial users and storm water run off can be present.
