Upgrading A 100-Year-Old Pump Installation In New Orleans

Finding just the right pump for an application can be quite a challenge, especially when the building presents several constraints. Sulzer updated a near antique installation.

Pilot Studies In North Carolina With Hydrex™ Odor Solutions

Two municipalities were faced with odor issues and required corrosion prevention in their collection systems. Monitoring in the sewer lines indicated peak H₂S atmospheric concentrations of 300-500 ppm. Both clients desired H₂S < 20 mg/L to prevent corrosion and preferably lower to prevent H2S odor.

EZ Valve Installed To Maintain Medical District's Water Supply

When a North Texas city identified the need to create a permanent control point as well as isolate an area so a repair could be made to a water main, they called on Texas Hot Taps for a solution.

City Of Windsor, Ontario, Improves Water Quality In Great Lakes With PolyBlend® Polymer Preparation System

The City of Windsor in Ontario, Canada, owns and operates two wastewater treatment plants.

Town Of Kittery, Maine Relies On Lime Feeders For pH Control For More Than 25 years

The Francis L. Hatch water filtration plant is in the coastal town in York county Maine and has an average capacity of 2.6 MGD. This is a surface water plant that utilizes hydrated or “slaked” lime (calcium hydroxide) to maintain the pH level around 7.0. For over 25 years, the district has used two of the UGSI Chemical Feed model 32‐055 Feeders to mix dry hydrated lime with water to create a lime slurry solution that can then be added to the finished water treatment.

Why A Little Knowledge About Sensors Can Be A Dangerous Thing

Every day our technical support people answer questions on the selection of sensors for pH, ORP, conductivity, dissolved oxygen and turbidity. No issue generates more confusion than cell constants for conductivity sensors. The vast majority of returns we process are for conductivity sensors that were ordered with the wrong cell constant. It turns out that cell constants are something that we all read but that most of us don’t really understand. Pick the wrong cell constant for a probe and your analyzer will happily give you numbers to 3 significant digits. The only problem is those numbers are wrong.

Precision Under Pressure: Engineering Custom Solutions For Pipe Emergencies

Emergency pipe repairs demand speed and accuracy. Custom engineered fittings ensure reliability in non-standard conditions, minimizing downtime, avoiding costly damage, and restoring service with precision and efficiency.

Michigan Utility's New Pumps Underscore Advancements In Wastewater Handling

Ypsilanti’s pumps, originally put into service in 1982, became priority candidates for replacement after operating ten years beyond their expected 20 year service life. The Ypsilanti Community Utilities Authority (YCUA), included the project in the utility’s Master Plan.

Plant Operations And Maintenance Staff Benefits From New Headworks

The high cost of maintenance and unsatisfactory performance of the aging equipment in the Bonnybrook headworks made it clear that significant changes were in order. The older poorly performing headworks allowed screenings to pass to the downstream process units causing operational and maintenance problems. By installing the Huber RakeMax® and matching WAP washpress, Calgary’s process performance immediately improved.

Seal The Deal: Shielding Against A Mag Meter's Achilles Heel

When it comes to metering water flow — drinking water or wastewater — full-bore mag meters offer many advantages. While the underlying technology based on Faraday’s Law of electromagnetic induction is shared among all styles of full-bore mag meters, specific implementations have impacts on longevity and accuracy. Here is what to look for when the time to choose arrives.

Veterinary Drug Residue Analysis Using The AutoMate-Q40: An Automated Solution To QuEChERS

QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.

Bridge Crossings And The Proper Use Of EX-TEND®, FLEX-TEND®, And Force Balanced FLEX-TEND Products

Of particular interest when it comes to bridges is the locating of pressurized water lines on and under bridge structures. Pressurized pipelines can present a number of unique challenges to the design engineer and utility owner.

Environmental Applications Of The Agilent 1290 Infinity UHPLC: The Evolution Of Chromatography This application note presents examples of the use of UHPLC (ultrahigh performance liquid chromatography) for environmental applications using the new Agilent 1290 Infinity LC. By E. Michael Thurman and Imma Ferrer Center for Environmental Mass Spectrometry Department of Environmental Engineering University of Colorado Boulder, CO, USA

Ultrasonic Level Measurement In Water And Wastewater Plants

Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry.

Filter Installations Remove Solids From FGD Scrubber Effluent

Power plants and refineries around the world must manage and treat complex effluent waste streams from the Flue Gas Desulfurization (FGD) process. Flue gas is generated by the combustion process of fossil and fossil-derived fuels, such as coal, oils, and natural gas in power plants. Petrochemical refineries may generate flue gas from a number of different processes, including Catalytic Cracking, Steam Methane Reforming, and Heaters or Furnaces.

Application Note: Preliminary Performance Study On An On-Line TOC Analyzer In Pharmaceutical Applications Total Organic Carbon (TOC) analysis is an effective technique for detecting and measuring the presence of organic contaminants in waters used throughout industrial processes, municipal water uses, and for determining residual concentrations of organic material on the surfaces of equipment used in the manufacture of active pharmaceutical ingredients. By Jeffrey Lane, Steve Skalski, and Gary Engelhart, OI Analytical

Process Optimization For Flow Measurement

The Saalfeld-Rudolfstadt Association in Germany must rely on cutting-edge technologies that optimize flow measurement in order to allow for smooth processes and supply 82,000 inhabitants with clean drinking water. 

What Are You Doing To My Pipe: Can PVC Pipe Be Loaded?

The argument has been used that PVC pipe is delicate and can’t be subjected to any kind of loading. In EBAA's years of testing we have found that is not the case at all. PVC can take an extreme amount of strain.

Pile Cloth Media Filtration Effectively Removes COD And TSS From Oil Refinery Wastewater

This application profile focuses on two test sites with different treatment requirements and describes how Aqua-Aerobic Systems’ OptiFiber® pile cloth media filtration was used at both sites to address the removal of harmful constituents from refinery wastewater.

Reducing And Reusing Water In Steel Manufacturing

The art of manufacturing steel for industries is well over 100 years old. Within this time, the steel business has fulfilled consumer needs, including construction, transportation, and manufacturing. The steel manufacturing process is quite intensive as it requires a lot of water to cool down the application. Steel plants constantly look for strategies that can help sustain the steel for a longer time by efficiently improving water and energy consumption.
