Severe weather events are some of the largest looming threats to civilization in the next many decades. The power of water is humbling, something that anyone who has ever been through a flood knows well. Floods can wreak havoc on urban communities, destroying homes, but also destroy environments, damaging wetlands and natural habitats.

For water system operators, contract engineers, OEMs, and reverse-osmosis (RO) membrane suppliers alike, the difference between expectations for RO membrane element performance and quantifiable performance in the actual operating environment can be fraught with surprises. This article addresses guidelines for establishing realistic RO warranty performance criteria and achieving those criteria in real-world applications.

By using Toray's low-fouling polyamide composite membranes, the WTPs at the AMATA estates operated the RO systems for more than five years before requiring replacement of the RO elements. This low rate of replacement has considerably helped the end-user save operational and capital costs and is noted as one of the most successful wastewater reuse plants in Thailand.

The Carrollton Wastewater Treatment Plant located in eastern Ohio, was upgraded from conventional activated sludge technology.

The Buxahatchee Wastewater Treatment Plant in Calera, Alabama was built in 1960. It upgraded in 1985 to a 0.75 MGD capacity extended aeration system with integrated clarifier and traveling aeration bridge for nitrification.

The City of Warren Water Recovery Facility in Michigan, treats and protects the waters of the state. Read the full case study to learn how the City of Warren Water Recovery Facility has been able to attain accurate data at a high repeatability rate since the installation of the Promag W unrestricted mounting 0 x DN electromagnetic flowmeter.

Ross Valley Sanitary District in San Rafael, California services approximately 47,000 mostly residential customers over a 27 square mile service area. They have 5 major pump stations, which is where Ross Valley found themselves having the most trouble. The existing channel grinders were simply not reliable. “It was a constant headache,” said Philip Marcantonio, Senior Collection System Worker. “The pumps were ragging up sometimes twice a week and sometimes twice a day.” The plant reported that the machines were not efficient at all. “It was a lot of extra work on us to keep the stations going,” Marcantonio said. On top of that, the constant downtime was causing even more than extra work; it was costing the district a lot of money. They knew this was not a sustainable system to keep their plant and stations running.

Finca Empacadora de Tilapia Milagro is one of the fastest growing and successful tilapia projects in Central America since its operation started in 2015.

A static headspace method was developed using Teledyne Tekmar automated headspace vial samplers to meet the method requirements of the Alcohol and Tobacco Tax and Trade Bureau of the US Department of the Treasury (TTB) method SSD: TM:2001 for testing fusel alcohols in alcoholic beverages.

Lack of sufficient straight pipe run made it impossible to successfully apply the preferred magnetic flow meter (magmeter) to accurately measure the flow of raw sewage.

Explore how additional costs for analytical conductivity measurement can be eliminated. 

Microbial contamination of food and beverage products is a potentially catastrophic occurrence resulting in foodborne illness or food spoilage. The same nutritive properties that render cheese and dairy products such a valuable food also provide an ideal growth medium for microbes if contamination occurs.

The Littleton/Englewood wastewater treatment plant, Colorado, put in place processes to effectively monitor the levels of ammonia in their wastewater treatment.

The 2000PV is a restraint for PVC pipe and the standardized mechanical joint. This product is the result of years of testing and evaluation and its performance has been proven by thousands of hours of proof tests, as well as third-party evaluations. This report describes the 2000PV through the 12" size.

Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons.

This application note explores the importance of maintaining a delicate balance in reverse osmosis systems to protect RO membranes.
