Learn how Hydra-Stop’s insertion valve provided new control points to mitigate future disruptions during a service line emergency.

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.

Memosens technology converts the measured value to a digital signal and transfers it inductively to the transmitter. With signal alarms in the event of transmission disruption, Memosens offers safe data transfer for increased availability of the measuring point and trouble-free processes. With Memosens 2.0, measuring points become completely future-proof and ready for IIoT.

Learn how a WWTP achieved remarkable cost savings with strategic utilization of advanced technology and wastewater intelligence. 

Learn how a WWTP increased visibility into its wastewater network to track the source of contamination. 

This project brief highlights how the town of Alpine utilized a CWRSF loan to replace the existing WWTP and address the failure of several local septic systems with MBRs.

A mid-size water system in the southeast was looking to pull together multiple measurements in a single panel. After reviewing off-the-shelf solutions, they realized there was nothing that met their requirements.

Have you ever installed a valve, only to have issues later because it was the wrong valve for the job? There are many options and several conditions that need to be considered when purchasing the right valve for the right application.

After the Missouri Department of Natural Resources reclassified the effluent receiving stream in the city of Sullivan, officials learned that its wastewater treatment lagoon required a more advanced treatment process to comply. They selected a continuous-flow sequencing batch reactor (SBR) system that utilizes a modified activated sludge biological treatment. The new infrastructure has provided cost-saving results for the ongoing removal of nitrogen and phosphorous.

This paper describes a newly developed microprocessor-based thermal dispersion mass flow meter that uses four temperature sensing elements in its flow sensor instead of the traditional two elements and automatically manages changes in gas selection, gas temperature, gas pressure, and outside temperature.

Precise pH control is critical in biomanufacturing processes to ensure product quality, consistency, and safety. This application note explores the challenges of pH management across bioprocessing stages and introduces Pulsafeeder’s NextStep pump as a reliable solution for accurate chemical dosing and process stability.

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.

Level controllers have evolved to meet today’s environmental challenges and industry demands. Learn how they support improved process management and, ultimately, a better bottom line.

FLEX-TEND® flexible expansion joints are designed to protect structures and pipelines from differential movement whether this movement is earthquake induced or the gradual motion of soil subsidence. This bulletin offers a concise listing and discussion of the important features and materials of the double and single ball assemblies.

Learn how a wastewater treatment plant in eastern Switzerland relies on the targeted use of flocculants to prevent sludge washout. 

Aeration has been a primary method for treating municipal and industrial wastewater for over a century. It is a natural way to reduce biological oxygen demand (BOD) and control odors. In the SBR process, aeration helps foster nitrification by bubbling air through the mixture of wastewater and activated sludge, encouraging the multiplication of aerobic microbes which consume nutrients and convert ammonia into nitrites and nitrates.

SensyMaster helps to improve the operating costs of the most cost intensive process in sewage plants: Aeration. High-measuring performance and state of the art technology helps customers increase plant efficiency.

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.
