AquaDisk® Filters Reduce TSS And NTU For Power Plant Process Water

Shepard Energy Centre (owned by Enmax and Capital Power Corporation) is located in Calgary, Alberta, Canada. It began operating in March 2015 and is capable of generating over 800 megawatts of electricity to Alberta residents using natural gas. The facility utilizes (2) combustion turbines featuring a combinedcycle technology to generate electricity, and in addition, processes waste heat through a steam turbine to produce even more electricity. This electricity generation process makes Shepard approximately 30% more efficient than traditional coal-fired plants, and reduces overall fuel costs. Not only is Shepard’s plant more efficient, but better for the environment by emitting less than half of the CO2 emmissions per megawatt hour compared to a coal generated facility. Sulphur dioxide and nitrogen dioxide emissions are also reduced.

Blowback From Flowback: Push For Groundwater Alternatives

About 50 percent of the nation’s residents source their fresh water supply from groundwater wells, which have deteriorated throughout the U.S. over the past decade. For shallow wells, severe drought conditions have gradually depleted groundwater levels.

Moving Towards Effective Management Of Produced Water

You cannot produce oil without water, because water is present naturally in both onshore and offshore oil reservoirs. This naturally occurring water is called produced water. Produced water has a simple to complex composition that is variable, and it is considered as a mixture of dissolved and particulate organic and inorganic chemicals (Al-Ghouti et al. 2019) with an average of 7 to 10 barrels of produced water being generated for each barrel of oil during the course of an operation (Guerra, Dahm, and Dundorf 2011).

New Hampshire Puts $350 Million To Work From A Successful Lawsuit Over MTBE Contamination

From cleaner water to infrastructure upgrades, good stories are easy to find after the state of New Hampshire set out to hold polluters accountable for contaminating groundwater with methyl tertiary-butyl ether (MTBE), a gasoline additive now banned or limited in several states. Through private well testing, watershed protection and new water facilities, the people of the Granite State are turning the tide on water contamination and restoring the safety and reliability of their drinking water supplies thanks to bold action to make sure polluters pay for damage.

Co-Digesting Food Waste With Wastewater Solids To Produce Energy

Inspired in part by California’s Senate Bill 1383, which was enacted to reduce organic waste and methane emissions, co-digestion is fulfilling those goals while converting wastewater treatment plants into water resource recovery facilities.

Potable Reuse Gets A Taste Of The Charles River

It was named by the infamous explorer Captain John Smith after the Massachusett tribe of Native Americans, then subsequently renamed by King Charles I of England after himself. As Boston grew, the mighty Charles River proved a vital force behind its expansion, and its long and winding history a reflection of the city’s own.

Repair Of Major Damage To High Density Polyethylene Wastewater Pipeline

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.

Increasing Consumption Of Processed Food To Proliferate Peracetic Acid Market

Domestic cooking has taken a back seat across several developed economies, given the steady rise in the female workforce and subsequent lack of time. This, along with significant improvement in disposable incomes, has been playing a critical role in accelerating the shift toward processed food and beverages. 

Potato Chips In Peru? Headworks Solves A Multinational Food & Beverage Company's Space And Effluent Quality Challenges

Although industry only accounts for 20% of water consumption globally (vs. 70% for agriculture and 10% for domestic consumption), most multinational industrial companies are now focused on ensuring they provide effective environmental management wherever they are in the world.  

The Future Of Hydroelectric Power: Balancing Generation With Environmental Impact As global climate goals and the environmental impact of hydroelectric systems draw increased attention, the conversation for energy leaders and water resource professionals has shifted from expansion to optimization, where smarter infrastructure and adaptive strategies must work together to reduce harm without compromising output.

Coal Ash Pond Polishing Filter System

A power plant's wastewater was being contaminated by coal ash generated from power plant operations. The plant was searching for a treatment/polishing system to maintain a TSS of less than 25 PPM. 

Natural Gas-Fired Combined Cycle Power Plant Improves The Performance Of Water Treatment System

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.

Offshore Platform Fire Safety Sprinkler System Depends On Liquid Flow Assurance Switch

Offshore platforms around the globe are essential to the production of oil/gas and the global energy supply chain, but they represent a daily hazardous operating environment to the employees that work there 24-x-7. The potential dangers range from a mix of toxic and combustible gases, including, but not limited to, deadly hydrogen sulfide (H2S) to explosive methane (CH4), and other mixed hydrocarbon gases that are easily flammable.

Design And Care Of Reverse Osmosis Systems, Part 3: Operation And Monitoring

Reverse osmosis (RO) systems offer power plant owners and operators a reliable and well-proven water treatment solution. However, designing and caring for an RO system requires a thorough understanding of a plant’s water supply and the technology’s capabilities. The final article of this three-part series will address RO system operation and maintenance best practices.
