It is estimated that nearly 75,000 miles of wastewater and water pipelines have been lined with Cured-In-Place Pipe (CIPP), with nearly $3 billion spent annually on the trenchless renovation method, worldwide. Recognizing the growing use of CIPP and inability of CCTV inspection to accurately or consistently certify trenchless rehabilitation as defect-free, this paper chronicles the emergence of new guidelines to test, certify, and accept CIPP lining projects, using Focused Electrode Leak Location (FELL) inspection.

California water reuse program provides multiple benefits, serving as a model for other municipalities.

For almost 50 years, CPS Energy of San Antonio has drawn water from the San Antonio River to recharge two man-made lakes that provide cooling water for their power plants.

Leprino Foods, the world's largest mozzarella cheese producer, operates two plants that share one wastewater pipeline – a 16” SDR11 High Density Polyethylene Pipeline (operating at approximately 160 PSI). During dirt work an “auger” hit the wastewater pipeline and drilled an 8” diameter hole in the line. Leprino needed immediate access to a repair fitting for this line.

Today, the drive toward more advanced technology is stronger than ever, as we expand our use of predictive modeling and data-centric solutions.

In August of 2007, the Michigan Department of Environmental Quality issued seasonal ammonia discharge limits for the Coldwater Wastewater Treatment Plant (WWTP), which included a daily maximum ammonia concentration of 2.0 mg/L between the months of May and November.

Learn why choosing or changing a defect catalog can have far-reaching implications for regional infrastructure.

In Part 2 of the Get Pumped Up series, explore the hidden flaw in traditional infrastructure planning: it’s too slow for today’s dynamic conditions.

The successful management of the world’s marine environment has unique challenges when compared to land based environments. The oceans encompass a huge area to manage, their political boundaries are blurry, and conditions in one small area can have serious impacts on much larger, far removed areas.

The New Rochelle Wastewater Treatment Plant is located in the Westchester County, New York, discharging to the Long Island Sound. It serves a population base of 65,000 people and is permitted to treat average flows of up to 20.6 MGD. Operating with primary clarification and pure oxygen-based activated sludge treatment since a 1979 upgrade, the plant only removed BOD and TSS from the wastewater.

For more than 20 years, USP Technologies’ comprehensive biosolids odor and corrosion control solutions have been extremely effective at reducing sulfides and other odor causing compounds in municipal and industrial wastewater treatment systems.

Tightening phosphate limits require high-precision monitoring to ensure compliance and economical chemical dosing. Refined photometric methods now offer superior accuracy at ultra-low ranges, providing the stable data necessary to optimize wastewater treatment processes.

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.

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.  

The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.

Hexanal is one of many well-documented aromatic components that contribute to flavor and aroma in common consumer food products containing omega-6 fatty acids. Hexanal content is also used to measure the oxidative status of foods rich in omega-6 fatty acids.

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

UV AOP performance verification requires a robust test matrix covering design, operating, and control conditions. This process includes on-site execution, sample analysis, and troubleshooting to achieve successful regulatory approval.

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.

Pesticide residue laboratories are required to undertake analyses of an ever increasing number of samples. The analyses typically involve use of multi-residue methods (both GC-MS and LC-MS) to test for over 500 pesticide residues.
