Cardston WWTP’s choice of a dewatering system to replace its belt press, Huber Technology Q-Press^®, has a striking comparison to the plant’s previous technology in both the footprint and the attention it requires. The Cardston staff also noticed striking improvements in water separation, end-product dryness and offensive odor by-product.  Read more about how the Q-Press^® helped Cardston become a better neighbor.

A few months ago I received a call from an angry user who was using one of our differential probes and a controller. Embedded in the probe is a thermistor that measures temperature.

Using a single programmable controller such as Schneider Electric’s M580 Safety Controller to manage both process and safety systems can help speed up deployment, improve reliability and sustainability of operations, enhance cybersecurity, and support greater productivity and transparency.

Storm water runoff from a 37-acre coal storage yard utilized as part of daily operations at an industrial site in Southwestern Pennsylvania posed a problem when the Pennsylvania Department of Environmental Protection (DEP) updated the facility’s NPDES permit.

Laboratory performance is critical for evaluating water treatment operations — from operational and disinfection efficiency to regulatory compliance reporting to human health and safety. Errors, oversights, or incomplete documentation can plague even the most finely tuned water treatment utilities. Here is a quick review of tools and techniques that can improve workflow accountability.

A North Carolina hog grower with a brood barn of 200 full-grown sows contacted Reliant Water Technologies seeking assistance with one of his waste lagoons. The plan was to locate an aerator on one end of the lagoon and allow for the forward flow of water from a coarse bubble airlift to ‘push’ the water forward.

Municipal wastewater treatment plant operators face significant challenges from a surge in clogs. Wipes that have been marketed as flushable, but don’t necessarily break down like toilet paper, are increasingly ending up in the waste stream. The proper mechanical solutions can help mitigate the problem and make operators’ lives easier.

Chemical programs are essential components of wastewater treatment. Whether the goal is phosphorus removal, odor control, improved solids settling, or final polishing, chemicals often play a vital role in meeting permit limits and ensuring stable operations.

Between 2001 and 2002, a faulty valve on a sump beneath a helicopter refueling oasis began slowly leaking jet fuel at the Wheeler-Sack Army Airfield of Fort Drum. When it was ultimately discovered in April 2006, it was estimated that approximately 350,000 gallons of jet fuel had been released into the ground, contaminating a three acre area of the base. newterra was contracted to provide remediation equipment to address the spill.

Learn how to choose a solutions provider that can act as a natural partner to both the WWTP and the design engineer for expansions, retrofits, or greenfield projects.

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.  

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.

The textile manufacturing industry encompasses many and diverse processes that rely heavily on the use of water, energy, chemicals, and other resources. Wet spinning, sizing, desizing, scouring, bleaching, mercerization, dyeing and printing are just a few. Monitoring and controlling the pH, TDS/Conductivity/Salt Concentration, ORP (REDOX), and Temperature of the aqueous solutions used in these processes conserves costly resources, controls quality, and reduces the amount of pollution that must be treated before discharge of effluent wastes. This can be done manually with handheld instruments or automatically with in-line monitor/controllers.

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.

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.

In wastewater treatment, aerobic digestion enables plants to increase their capacity by injecting oxygen into the wastewater head space.

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

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

Despite their importance in modern wastewater applications, not all DAFs are created equal. Factors, such as the components that make up these systems, will influence how well they work and how long they last.
