As old gas & oil fields play out, newer methods must be used to extract resources from areas where they are locked in layers of shale. One current technique is known as “fraccing,” in which high pressure water is pumped into the well shaft to “fracture” the rock layers, allowing more natural gas to escape and be collected. However, this technique poses a number of environmental problems, including contamination of water with hydrocarbons, solid particulates, and scale producing ions — making it unsuitable for reuse.

The flare gas discussion is heating up again. According to the Bureau of Land Management (BLM), U.S. oil production is at an all-time high, and so are the harmful methane emissions from leaks, flaring and venting.

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 new generation of electrocoagulation-based water treatment has successfully treated wastewater and effluent from a remote onshore natural gas exploration and production project with over three years of continuous operation. To compound the challenges of treating this wastewater and effluent, the unit was required to operate in an extremely environmentally sensitive environment — a pristine tropical rainforest.

A high-tech “net” and the power of the sun are all that is needed to remove contaminants from water produced by fracking operations, oil spills, textile manufacturing, and other sources.

This is the second in a series of articles and case studies examining the emergence of sustainably-driven innovation within the wastewater treatment functions of the food and beverage industry as sustainability and production issues intersect and influence how companies manage their wastewater.

Every year, World Water Week, a conference organized by the Stockholm International Water Institute(SIWI), brings together experts from around the world to discuss global water issues. This year’s event focused on Water, Ecosystems and Human Development, with discussions concentrating on how business, NGOs and government agencies are collaborating to address water-related challenges.

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.

Read about a technology that dairy plants can take advantage of to optimize the treatment of their wastewater and assure consistent compliance to effluent discharge permits.

One Friday evening in the spring of 2019, Abhi Upadhyay, assistant professor of food microbiology and safety in the Department of Animal Science, found himself watching a video showing microbubbles for pet care and grooming. He started thinking about using this technology for food safety and spent the weekend researching its potential, current state of the field and appropriate grant opportunities.

Substances regulated or substances unregulated may ultimately impact the environment, health, and water supply of others. The following safety considerations are advised for those who store, handle, or transport potentially dangerous substances.

This paper shows how the four pillars of operator effectiveness lead operators to greater awareness, faster response and better decisions.

Since EPA released its proposed Clean Power Plan (CPP) in June of this year, the plan has been a hot topic in every state.

There's a hidden threat to Indian energy companies' revenues — water.

The client was in need of both a raw water and wastewater treatment system for its new 1,100-megawatt (MW) natural gasfired combined cycle power station that was being built to replace an existing 400-MW coal-fired plant that had been decommissioned previously. Veolia Water Technologies was contacted to engineer, procure and supply a 6,000 gallons per minute (GPM) raw water treatment system and a 1,200-GPM wastewater treatment system.

Five months after leaked chemicals contaminated the public water supply, West Virginia passed legislation to prevent future tank failures — and perhaps serve as a model for others. By Yves Pollart, P.E., BCEE

Nutrient pollution is one of America’s most widespread, costly, and challenging environmental problems. This pollution can occur when excess amounts of nutrients, such as nitrogen and phosphorus, run off from land into streams, rivers, lakes, and other water sources. To help water quality managers reduce nutrient pollution, EPA researchers developed the River Basin Export Reduction Optimization Support Tool (RBEROST), a regional online tool currently available for the Upper Connecticut River Basin that provides low-cost solutions to meet nutrient load targets.

The town of Cary, North Carolina, is an affluent municipality located southwest of Raleigh. The town is near the center of the Triangle region, a commuter area consisting of three major universities: Duke, UNC and NC State as well as the technology hub located in Research Triangle Park. The housing development of Preston is located adjacent to the Prestonwood Country Club, where housing values range between $300,000 and $1M. Bridle Creek Dr. is the main entrance to the community, and the golf course with Bridle Creek crossing though a triplet of 52”-54” CMP culverts. In 2016, a section of one of these culverts collapsed, creating a sinkhole on the side of the road. The collapse was quickly repaired with a new section of CMP, but the community was concerned that the remaining CMP sections were showing corrosion in the invert and it would be only a matter of time before a more serious collapse occurred.

Times have changed in Washington state’s Skagit County, perched just 25 miles south of the Canadian border. Skagit County, which extends across 1,920 square miles, maintains one of the largest and most diverse agricultural communities west of the Cascade mountain range. Over 90 different crops are grown in this fertile valley, including blueberries, raspberries, strawberries, tulips, daffodils, pickling cucumbers, and specialty potatoes.

We work with many clients across the continent, and it has become very simple to see a trend in their types of questions and concerns. From these trends, you many times find that an effect of an issue can mask the real problems that are occurring. Rolling element bearings heating up are a common occurrence that can have many different causes.  However, the heat, is really only an indicator and not the actual cause of the problem.

Guardian Industries Corp.’s float glass plant in South Carolina was in search of a crusher to aid in their glass production process. They needed a unit that could break up the electrostatic precipitator material and prevent pneumatic transport plugs. Without the efficient breaking of these lumps, the process was interrupted, wasting time and money.

The flare gas discussion is heating up again. According to the Bureau of Land Management (BLM), U.S. oil production is at an all-time high, and so are the harmful methane emissions from leaks, flaring and venting.
