Wet Weather issues have evolved over the last generation. From an environmental side issue twenty years ago, they have gained the forefront of environmental concerns. This paper will present the key steps to achieve a global approach to Wet Weather issues. Each of the best management practices available have been ranked and reduced to critical steps that can be implemented sequentially in order to achieve an optimized global approach to wet weather issues.

Combined and sanitary sewer overflows are natural hazards for wastewater collection systems. Without a comprehensive solution to monitor troublesome conditions, overflows can be triggered with little warning and lead to expensive and embarrassing situations. Fortunately, versatile analytical systems that capitalize on existing wastewater collection infrastructure hold promise for avoiding such negative impacts.

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.

The Bordeaux region of St. Thomas had a pressing need for a wastewater treatment plant that produces high effluent quality. Its existing plant was old and did not meet regulation nor industry standards. Fluence, together with its partner SD&C Inc., built an MABR-based wastewater treatment plant from the ground up, utilizing whatever existing pieces of equipment could be used from the old plant.

The students at the University of Miami will know firsthand the importance of rethinking the way we handle wastewater and water with a Net-Zero water treatment system on site.   The project showed the viability and feasibility to take buildings off the water grid to provide water recycling and how it can be achieved without raising the cost of high quality water.

Jet aeration improves nutrient removal by delivering superior oxygen transfer, intense mixing, and flexible process control—cutting energy use, enhancing BNR performance, and supporting long-term operational reliability.

Clean water is a necessary resource for life, business, and the environment in which we live throughout the world.

Recognizing pH's pervasive influence empowers operators to achieve consistent and reliable outcomes in every facet of water and wastewater treatment, underlining its indispensability for clean and safe water systems.

Variable area (VA) flow meters offer an economical solution in many hazardous wastewater applications, as well as a variety of other uses, but are often overlooked by engineers and plant operators who think a higher level of flow measurement technology is necessary. 

As oil prices remain high, we are in the midst of a nation-wide initiative to seek renewable sources of energy to increase energy efficiency and energy security. Renewable energy accounted for 13.2% of the domestically produced electricity in 2012. Among the sources of renewable energy is the production of biogas from landfill gas (LFG) or digester gas.

Energy costs continue to increase. At the same time, there is increased pressure to reduce utility bills without sacrificing operations or comfort.

This application note explores a test which demonstrated significant improvements in Oil-in-Water monitoring of industrial wastewater in comparison to the weekly grab sample analysis method.

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.

A wastewater treatment plant separates solids from the liquid, and consists of two basic stages: primary treatment and secondary treatment.

This application note will explore how active control programs lower operational costs of compliant contaminant removal. 

A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.

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.

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.

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.

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