The City of Belleville, Ontario, planned on re-developing downtown waterfront property into a public space, but there was one problem: the history of the site had led to groundwater contamination.  

This uranium, arsenic and gross alpha removal pilot study was conducted for the Schurz Elementary School treatment facility in Schurz, Nevada. The Schurz Elementary School well contains concentrations of uranium, arsenic and gross alpha in excess of the State regulated Maximum Contaminant Levels (MCL).

Water and wastewater plant operators often encounter challenging screening situations that aren’t well served by conventional products. This includes deep channel applications, where space is very limited, as well as high-flow applications. To address these growing demands, Parkson recently expanded its Aqua Caiman® line to include the Aqua Caiman® Vertical and Aqua Caiman® HD.

There is a newly-developed technology, the so-called PeriFilter® that will hit the market within the next few weeks. This offers many heretofore technological and economic advantages in the separation of solid phases from liquid phases with concomitant transformation of the solid phases into processable forms for further usage and/or products.  It may be used in the separation of solids from liquids in water purification and in wastewater treatment applications as well.

For most water or wastewater system operators, engineers, and repair crews, the only thing worse than facing a 24”-main emergency repair is facing an even larger one. To those who have never performed an emergency line stop and bypass, the idea of completing repairs with no service outage, no long-term shutdown, and no ‘boil water’ notice is almost beyond belief. To those who have, it’s a sigh of relief.

Edward Paro of Sulzer compares the strengths and weaknesses of two rival turbocompressor technologies: air foil bearings and active magnetic bearings.

Fairfield Wastewater Treatment Plant in Butler County, Ohio was having a lot of trouble with their grinders. The plant serves over 42,500 domestic customers, a number of commercial and industrial institutions as well as Mercy Hospital of Fairfield. They treat about five million gallons of wastewater collected in over 175 miles of sewer pipe each day.

Daurala Organics Limited, a chemical producer in Daurala, India, managers 2780m³/d flow in their activated sludge process plant.

As a young engineer on a farm in California's Central Valley grappling with the challenge of injecting fertilizer into irrigation water, Angelo Mazzei didn't consider how his career would ultimately turn his knowledge of water into a deep involvement in wine. But since he crafted first high-efficiency venturi injectors in the 1970s in his garage to help improve water, fate and business have pulled Angelo Mazzei toward wine from every direction.

Clean-in-Place (CIP) systems are critical for industries where hygiene and contamination control are mandatory—such as food and beverage, pharmaceuticals, and specialty chemical manufacturing. These systems automate cleaning through validated, programmed steps that ensure compliance with stringent safety and quality standards. This application note explores the challenges of CIP operations and demonstrates how Pulsafeeder’s NextStep pump technology addresses these challenges with precision, reliability, and cost efficiency.

Read an overview and maintenance tips for chain and scraper systems. 

Providing the best value to wastewater customers requires a team of operators that have a deep sense of ownership and are committed to continuous improvement. Such is the case for the operating staff at one wastewater treatment plant whose progressive attitude and a philosophy of “do it right” led them to an investment in online instrumentation and SCADA for compliance, monitoring, and control.

A new pipe-repair solution promises to save time and money, while also being sustainable, long-lasting, fully scalable, and safe for workers.

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.

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.

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

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

As flooding increases along coastal and river-adjacent communities, the need for low-cost, reliable monitoring and warning systems has become a critical factor for managing these issues in real time, without requiring major infrastructure overhauls.

Industrial power plants or co-generation power plants utilize steam for industrial purposes other than power production.
