GE partnered with the Wharton School's Initiative for Global Environmental Leadership (IGEL) for an industry leaders' discussion about the energy/water nexus in unconventional oil & gas production.

The client is one of the largest combined electric and gas companies in the United States, servicing 1.8 million gas customers and 2.2 million electric customers in more than 300 urban, suburban and rural communities. Following a successful site visit, the Client contracted Veolia for the treatment of up to 2725m³/h (12,000 gpm) of sewage plant effluent for cooling tower make-up.

Large, distributed water networks are not well-suited for conventional water monitoring processes which rely on manual sampling and lab testing. In particular, this midstream oil and gas company had a need to detect Iron, Selenium, and other heavy metals at a precise level comparable to a lab. In addition, it wasn’t feasible to manually test the entire water system at the requisite frequency. Finally, instrument reliability and unplanned downtime were an issue.

Late last month, a panel of regulators appointed by Governor Rick Scott narrowly approved the first changes to Florida’s surface-water quality standards since 1992. Marked with adamant support on one side and passionate protest on the other, the sweeping amendment has left questions about how clean Florida’s water will be.

Ambient dust from construction and from the environment was contaminating the campus cooling tower system resulting in contamination buildup in the cooling tower equipment. This required significant labor hours to clean and frequent blowdown, resulting in higher water usage than was desired.

A global beverage company produces, markets, sells and distributes a variety of beverages including beer, malt, soft drinks, fruit juices and mineral water. The brewery has utilized several types of SITRANS F flowmeters from Siemens to regulate all aspects of the brewing process for more than a decade, including SITRANS F C Coriolis meters to monitor the sugar concentration in wort prior to fermentation.

The dairy industry undertakes a number of activities that involve converting raw milk into milk, butter, cheese and yogurt using processes such as chilling, pasteurization, and homogenization

Microfloat Dispersed Air Flotation (DAF) System is an effective, affordable, and reliable physical/chemical pre-treatment technology for removing up to 90% free-floating FOG, 60% TSS, and 30% BOD*– all at a much lower cost than traditional DAF systems.

In 2012, Americans consumed well over 79 billion servings of tea, which is just over 3.60 billion gallons.

Industrial companies need reliable water treatment technology, since failure of a water system may result in downtime for production, with significant financial impacts. Ultraviolet (UV) technology is used for water treatment in various industries such as microelectronics, food & beverage, pharmaceuticals, and many other industry segments.

A natural gas-fired combined cycle power generation facility located in Idaho contacted QUA to find a solution to improve the performance of a water treatment system used to recycle the plant’s cooling tower blow down water.

After an international tender process, the Israel Electric Company (IEC) chose Fluence to design, manufacture, and supply containerized ultrapure water production systems for use as makeup water for heat-recovery steam generators (HRSG) and for NOx emission reduction at recently upgraded power plants across Israel. More than 15 units of 20 m3/h production modules, each fitted in two 40-foot shipping containers, were provided to seven power plants. Their compact design allowed for ease of installation, operation, and maintenance while meeting the customer’s demanding engineering standards.

A look at the market dynamics and drivers for ultrapure water treatment reveals multiple industries with growing demand, including one that stands above the rest.

When an energy storage facility in New York, USA was looking for a way to improve the efficiency of their power generating turbines they did not have many options to choose from. Because of the sheer size, the space limitations and performance requirements of the application, the only option was to install a SITRANS FS230 clamp-on ultrasonic flow meter from Siemens. 

This Hamilton Project memo presents nine economic facts that provide relevant background context to the water crisis in the United States.

Chicago continues its long tradition of innovative biosolids management by introducing a new model for sustainability and community service.

Imagine H2O recently announced the 10 finalists from more than 90 worldwide entrants to its Water Data Challenge. Here’s a brief overview of each company and what they offer.

Los Angeles Sanitation collects, cleans, and recycles solid and liquid waste generated by residential, commercial and industrial users in the city of Los Angeles and surrounding communities. The system serves over four million residents. The Bureau of Engineering for the Department of Public Works is responsible for maintaining the sewer and stormwater systems owned by the city. Over the last several decades, the city has worked to rehabilitate and replace much of its aging sanitary sewer system. As the progress continues, the city is now doing more work on the larger diameter piping structures in its system. These larger diameter rehabilitations are significantly more costly than the smaller diameter repairs and many of the systems employed by the city are significantly budget constrained.

The West African City of Abidjan in Côte d’Ivoire has historically provided drinking water to its five million residents from water treatment plants that use hydrated lime systems. But because of the high content of carbon dioxide in the local groundwater, up to 160 ppm, setting the water to calcium carbonate equilibrium using hydrated lime was economically, operationally and environmentally challenging for the city of Abidjan.

A global beverage company produces, markets, sells and distributes a variety of beverages including beer, malt, soft drinks, fruit juices and mineral water. The brewery has utilized several types of SITRANS F flowmeters from Siemens to regulate all aspects of the brewing process for more than a decade, including SITRANS F C Coriolis meters to monitor the sugar concentration in wort prior to fermentation.

The use of hydrogen peroxide to supply supplemental dissolved oxygen (DO) to activated sludge and other biological treatment systems is well documented and has been successfully practiced for decades.

A Phosphorus mine in Wyoming needed to treat high selenium concentrations leaching into the surface water. Read the full case study to learn how Toray projected to save the plant energy costs for years.

A study conducted by the state of Washington’s Department of Ecology and the EPA assessed the efficacy of PPCP treatment removal rates of various wastewater treatment processes.

Five decades ago, ion exchange using charged resins was one of two processes used in the water industry for water treatment.

U.S. and Canada industrial sector withdrawals have declined 30 percent over the last three decades to 152 BGD. This trend, which is expected to continue, has been sparked by water-related technology improvements at facilities, company strategies to mitigate water supply risks, and outside pressure to better manage wastewater effluent through regulations and rising discharge costs.
