Video Case Study: SPIRALIFT® SR Provides Septage Receiving Solution

The Willits, California Wastewater Treatment Plant services over 10,000 residents and receives 750 loads of septage each year, but found they had a serious problem. Heavy septage from “honey trucks” was dumped by haulers into its wet well which clogged the plant’s pumps and caused flow channels to overrun. The plant also lacked oversight as to who was pumping and what was being pumped into its system. It could not control the pH level of the wastewater. 

WWTP Reaches Clog-Free Operation With Self-Cleaning Impellers

As with many plants modified for activated sludge treatment, the existing infrastructure at the Adams Field Wastewater Treatment Plant in Little Rock, AR, allowed rags and other debris to clog the impellers of the submersible pumps. One of the plant’s two 15-horsepower pumps was replaced with an 18-horsepower RAS submersible pump with a self-cleaning impeller, virtually eliminating the clogging problem by simply pumping away any debris that reaches the pump intakes.

Optimizing Aeration Reliability In Food And Beverage Wastewater Applications

In addition to penalties for non-compliance, wastewater treatment plant (WWTP) operators in the food and beverage industry risk excessive losses caused by problems at the wastewater treatment facility.

Optimizing RO-Membrane Performance In Produced-Water Applications

Here are several important considerations for getting maximum value from produced-water RO treatments at minimal total lifecycle costs.

When To Consider An Alternative To Thermal Dispersion Meters

Maintaining a firm grip on blower output within digesters at wastewater treatment plants is the key to stable dissolved oxygen levels that support an optimal biological cycle. However, the most common type of device used to measure aeration in the activated sludge process — thermal dispersion flow meters — is not always the best fit. The good news is that wastewater plant operators have multiple alternatives.

Ensuring Healthy Aquaculture: The Role Of Water Quality Monitoring

Real-time monitoring with fluorometers and turbidity sensors ensures optimal water quality in aquaculture, enhancing fish health, preventing disease, and promoting sustainable seafood production.​

Aerzen Combines Blower Technology And A New Control System For Energy Saving Operation Even In Case Of Load Changes

If modernizations in wastewater treatment plants are due, as a rule the permanently reducing limit values of ammonium, nitrate and phosphate are pushing the investment decisions.

Emergency Bypass For Sewer Facility Circumvents Natural And Manmade Obstacles

When operators at the Rivanna Water & Sewer Authority (RWSA) in Charlottesville, Virginia discovered a compromise in the 54-inch secondary effluent water line at their Moores Creek Advanced Water Resource Recovery Facility, they took immediate action to address the problem.

How To Save Time, Save Money With Pilot-Plant Testing

When developing water or wastewater treatment processes for entirely new applications or modifying existing processes to accommodate changing water characteristics or regulatory discharge requirements, understanding capital investment, operating cost, and long-term performance is critical. Here are several ways to view pilot-plant or lab-scale testing as viable approaches to better outcomes with lower risks.

Maximizing Your ROI On Test Equipment

In today’s economic climate, it’s tempting to want to buy the cheapest test equipment you can now. But, how can you tell what the true cost of test equipment is? You have to consider how widely your water and chemical consumption will vary as the readings on your instrumentation does. By Heather Rekalske, Myron L Company

Pikeville, Kentucky Medical Center Leak Found Despite Ambient Noise

Leaks found in 60 psi high density PE pipe by FELL in less than three hours. Acoustic and CCTV failed to find any leaks after more than a year of investigation. Read the full case study to learn more. 

AquaSBR Systems Above 10 MGD

This application note will explore installations of AquaSBR Systems worldwide in a variety of municipal and industrial applications. 

Comparison Of Ultra Low Range Total Chlorine Residual Limits Of Detection And Quantitation Across The Water Industry

Limits of Detection and Quantitation are key to understanding analytical instrumentation capabilities, especially when non-optimal process control can lead to damage of sensitive equipment due to insufficiently accurate readings.

Repair Or Rethink

The Moundsville Wastewater Treatment Plant in West Virginia chooses not to fix a broken blower unit, but rather to correct an outdated approach. The result is a savings of $50-60K a year in energy costs.

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.

Reducing And Reusing Water In Steel Manufacturing

The art of manufacturing steel for industries is well over 100 years old. Within this time, the steel business has fulfilled consumer needs, including construction, transportation, and manufacturing. The steel manufacturing process is quite intensive as it requires a lot of water to cool down the application. Steel plants constantly look for strategies that can help sustain the steel for a longer time by efficiently improving water and energy consumption.

Ion Exchange Resins Reduce Pollution From Refineries

A single operational oil and gas refinery produces millions of gallons of contaminated wastewater a year, leading to environmental pollution concerns. Ion exchange resins are a metal- and ion-removal solution to help clean this wastewater for plant reuse or safe disposal. This application guide explains how resins can be used to demineralize refinery water in process, boiler, and cooling water applications.

MEGA-STOP Bell Protection System Aids In Pipe Joint Assembly

Water and wastewater piping come in a variety of materials, joints, and diameters. They can meet a multitude of demands and needs for the country's infrastructure.

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.
