Large, distributed water networks are not well-suited for conventional water monitoring processes which rely on manual sampling and lab testing. In particular, this midstream oil and gas company had a need to detect Iron, Selenium, and other heavy metals at a precise level comparable to a lab. In addition, it wasn’t feasible to manually test the entire water system at the requisite frequency. Finally, instrument reliability and unplanned downtime were an issue.

Calera Creek Water Recycling Plant, located in Pacifica, California, recently retrofitted to the Thermal Process Systems’ ThermAer™. This is California’s first installation of the second generation ATAD system.

Serving over 200,000 ratepayers, the City of Tacoma operates two award-winning wastewater treatment plants. The Central Wastewater Treatment Plant and the North End Wastewater Treatment Plant are considered state-of-the-art, but operate differently.

The City of Marengo, Illinois operates an activated sludge wastewater treatment plant that processes an average volume of 1.8MGD with a maximum capacity of 5.94MGD. In the fall of 2007, the operators of the plant began to observe reduced performance of their liquid-polymer feed system that was in place at the city’s facility. The Dynablend™ liquid-polymer unit was a good fit for the Marengo plant because of its reliability and performance over a wide range of polymers commonly used for sludge processing.

Today’s aeration equipment has overcome past concerns regarding energy efficiency and operating lifespan which are making deep aeration tanks an ideal solution for select wastewater applications.

Reclaimed water systems, powered by MBR technology, offer developers a sustainable, cost-saving solution that meets rising water demands, eases permitting, and aligns projects with future environmental expectations.

The Village of Johnson Wastewater Treatment Facility (WWTF) was among the first in the state of Vermont to meet newly enacted secondary treatment requirements when it began operation in 1970.

Planning how to address environment-impacting, water-infrastructure challenges — reducing stormwater runoff pollution, reducing sewer overflows, and protecting rivers and streams that serve as drinking water supplies for downstream towns — can be an intimidating task. A recent report from the Environment America Research & Policy Center cites many examples that can serve as beacons for municipalities large and small.

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

Hydrogen sulfide (H₂S) gas in wastewater environments is a familiar concern. But waiting until its odor is detected can be too late to exert as much control over it as desired. Fortunately, a new ability to monitor H₂S concentrations — in the liquid wastewater stream, in real time — is advantageous for wastewater professionals in terms of safety, cost, and consumer complaints. Here are four ways to capitalize on that capability.

Learn about filtering microplastics from industrial wastewater prior to discharge, and how this is one way to effectively reduce the volume of this waste material from entering our surface water.

This application note explores how Greenline pumps enhance odor control systems by delivering precise chemical dosing for odor mitigation and pH control, ensuring cleaner air and improved quality of life.  

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.  

Read about managing water discharge into a mixed water drainage system, electromagnetic flow measurement of water loads, and automated discharge control by way of a structure with overflow. 

A water purveyor was in urgent need of a chemically resistant flow instrumentation with a long life of service that allowed reliable and long-term stable dosing of the sodium hypochlorite solution.

The C445 motor management relay offers the most configurable protection options in the industry, with features specifically designed to protect critical pumps from costly damages due to dead-head and other underloaded or starved pump conditions.

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.

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.
