The Future Of Fracking: Evaluating Emerging Technologies

How can the U.S. and other countries profit from hydraulic fracturing AND protect water resources? New technologies hold the key to environmentally responsible shale-gas production.

Diamond Electrode Wastewater Treatment Shines Bright

No business wants the word "toxic" associated with its operations. The world has grown very weary (and wary) of companies that aren't environmentally responsible. So while toxic wastewater as a byproduct of mining, oil refining, or other industrial processes isn't new, the impetus to treat these streams is steadily rising.

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.

Making The Best Of A Bad O₂ Situation

A balanced wastewater process is a beautiful thing — plenty of biochemical oxygen demand (BOD), plenty of O₂, and all those hungry little microbes are fat and happy. But what can be done when dissolved oxygen (DO) takes a nosedive and there’s not enough O₂ to satisfy industrial and food processing BOD? Here are some preparations to consider before wastewater treatment goes completely out of whack.

Frozen Vegetable Supplier Exceeds Effluent Requirements With MBBR

A frozen vegetable company was the premier supplier of individually quick-frozen onions, potatoes, roasted potatoes and vegetable blends to large food service companies. At their processing facility, a significant barrier to growth was faced due to an aging wastewater treatment system, which could not treat the anticipated flows that a plant expansion and production increase would generate. 

Are You On The Hook For U.S. EPA Effluent Limitations Guidelines?

While wastewater effluent standards mandated by the U.S. EPA and individual states eventually come down to a number, it pays to understand how those standards are established and the challenges of meeting them in real-world applications. Here is a look at the multiple pieces of that puzzle, including their wastewater treatment implications for industrial-scale meat and poultry processing operations.

Dairy Crest Davidshow Creamery in Camelford, England is the largest cheddar cheese manufacturer in the UK.

5 Approaches to Treating Wastewater in Beverage (Dairy) Production

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

FEDI System Has Been Running Successfully For Six Years

Brazos Electric Cooperative Power Plant in Cleburne, TX is a nominal 258 MW combined cycle gas fired power plant operating on AGC (Automatic Generation Control) load requirements. The plant uses approximately 54 million gallons of water per year for boiler feed water and NOx control of its combustion turbine.

Automatic Self-Cleaning Scraper Strainers Filter Smallest Particles To Largest Debris

Unlike backwash systems, scraper strainers reliably resist clogging and fouling when faced with micron-sized particles, oversized solids, and high solids concentration.

From Drought To Deluge: Gauging The Impact Of Western Rains For a number of years now, we have heard of dwindling water supplies in the western part of the U.S., but 2023 brought "atmospheric rivers" that (literally) flooded the Golden State and filled 12 of its 17 major reservoirs above their historical averages for the start of spring. It's a double-edged sword when such extreme weather arises, and obviously important to learn from the experience to better prepare for future events and plan for both resiliency and sustainability.

Cloth Media Filtration Removes Coal Ash And Coal Fines At Power Plants

Coal-fired power plants generate coal fines and coal ash from a number of sources, including coal combustion residuals (CCR), particularly fly and bottom ash from coal furnaces, and coal pile runoff during rain events. In support of an industry-wide effort to reduce, improve, and remove coal ash ponds, a variety of technologies have been tested and employed. Read the full application note to learn more.

Hydro-Electric Power Station Benefits From The Use Of Siemens Flow Meters

A power plant plant experienced an accident when a pipe broke after it was sand-dusted during maintenance. The pump location, including the turbines and control room, was completely flooded. Read about the customer's search for a cost-effective flow measurement solution to drive a safety shut-down valve in case the pipe should break again.

EPA's ENTACT Study Breaks New Ground With Non-Targeted Research

EPA scientists are leading a multi-phase project to evaluate the ability of non-targeted analysis laboratory methods to consistently and correctly identify unknown chemicals in samples. EPA’s Non-Targeted Analysis Collaborative Trial (ENTACT) was formed in late 2015 and includes nearly 30 academic, government, and industry groups. Non-targeted analysis involves analyzing water, soil and other types of samples to identify unknown chemicals that may be present, without having a preconceived idea of what chemicals may be in the samples.

New Methods Extend Options For NPDES Compliance Testing

The National Pollutant Discharge Elimination System (NPDES), introduced as part of the 1972 Clean Water Act, has continued to evolve as new challenges and new technologies emerge. Its latest update, due to go into effect on July 19, 2021, expands the analytical test methods available to governing bodies, industries, and municipalities for compliance reporting under the NPDES permit program. Here is what that entails.
