Breakthrough Technology Is Good For Fracking — And The Environment

The Department of Energy (DOE) is funding a demonstration project that remediates acid mine drainage water, providing both source water and useful byproducts for hydraulic fracturing operations.

Resolving High PH For Mining Operations

For an open-pit taconite mining operation in Minnesota, high pH groundwater required round-the-clock pumping to comply with discharge permit limits. After management installed a control system to neutralize the pH, the treated water leaving the site now meets permit limits. Read this case study to learn more about the installed system and results.

Helping Breweries Cut Natural Gas Costs And Waste Gas Emissions

No matter whether consumers choose a pilsner, an ale, or another popular type of beer, there is a critical focus at nearly all breweries today on their production process energy (natural gas) costs and plant environmental compliance (waste gas emissions). Failing to pay attention to the efficiency of these processes at breweries or any other type of food and beverage processing plant can lead to cost competitiveness issues and hefty regulatory fines.

Refinery Wastewater: Benefits Of Remediation By Electrocoagulation

Crude oil is a fossil fuel formed from long-dead organisms subjected to intense heat and pressure underground. This resource is the main ingredient in the production of gasoline, diesel fuel, lubricants, kerosene, propane, and asphalt. All of these products can be made in a single refinery through a complex branching series of chemical processes. The central refining process is atmospheric distillation whereby the crude oil is fractured into different components based on their differing boiling points. Each of these fractions will be sent along to separate process to be turned into the different oil products. Therefore, remediation of refinery wastewater from these different processes can be quite complex.

Breakthrough Recyclable Polyimide Membranes Transform Wastewater And High-Salinity Water Treatment

Researchers have developed polyimide-based membranes for membrane distillation (MD) that overcome three persistent issues in membranes for water treatment and gas separations: the need for pore-forming chemicals that prevent recycling, performance degradation due to pore wetting and fouling, and the inherent trade-off between high water flux and selectivity.

Determination Of Hexanal In Foods Utilizing Dynamic Headspace

Hexanal is one of many well-documented aromatic components that contribute to flavor and aroma in common consumer food products containing omega-6 fatty acids. Hexanal content is also used to measure the oxidative status of foods rich in omega-6 fatty acids.

Fresh Air, Fresh Fish

Farming operations to plan and control fish reproduction have been around since the 15th century and are a sophisticated, mechanized arm in the food production industry today. In Poland, traditionally, trout farms are relatively small family businesses where product quality remains high during every stage of the process. Learn how Kaeser’s rotary blowers turned a rural fishpond into an automated aqua farm by delivering air to ensure the fish are raised in the best possible environment.

Maximizing Speed And Accuracy In Microbiological Testing

A quality outcome is only as reliable as the components and processes used to create and test it. When it comes to municipal drinking water, food, beverages, wastewater effluent, and other industrial applications, having reliable microbiological testing reference materials to benchmark quality control (QC) processes is essential. Here are some important points to consider when establishing or managing QC programs.

Use Of Pure Oxygen To Resolve Capacity And Odor Problems

The Escalon Industrial Waste Water Treatment Facility’s service area is seasonal and centered on tomato and pickle processing. The production season (roughly mid-July through mid-October) sees high hydraulic- and BOD loads that strain the facility’s capacity. During the high season highly variable BOD load depletes DO and causes permit violations and odor complaints. Praxair installed 4 X 15 HP Medium Velocity Oxygenation (MVO™ oxygenation system), with the ability to deliver up to 6 TPD of oxygen to supplement the existing aeration capacity at the facility.

From Waste To Power: How Floating Solar Panels On Wastewater Ponds Can Secure Electricity

Wastewater ponds may seem an unlikely place to look for solutions an electricity security crisis. But their underutilized surfaces could help tackle two problems at once — high power prices and algal growth.

CleanFlo™ Monoscreen® Case Study

When the polar bears at the Brookfield Zoo were introduced to their new habitats at the Great Bear Wilderness, they had no idea how much more fulfilling their life would become.

Power Resiliency Tips For Water And Wastewater Utilities

Are you prepared to keep services up and running if the grid goes down?

Power-Gen Efficiency Boosted By Clamp-On Flow Meters

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. 

City Of St. Cloud Relies On Thermal Flow Meters For Digester Biofuel Co-Gen Power Process

The City of St. Cloud, Minnesota, straddles the Mississippi River near the center of the state a little more than 65 miles north of the twin cities of Minneapolis-St. Paul. The city’s forward thinking staff began looking for sustainable green energy solutions in 2003. After planning and initiating a series of projects over several years, the site is today producing renewable energy with a 20 kW rooftop solar array, a 220 kW solar array and biofuels electricity generation.

Unlocking Efficiency: The Advantages Of Peristaltic Pumps Peristaltic pumps have emerged as a revolutionary solution in industrial pumping, offering a myriad of benefits over traditional pump technologies. Fundamental to these pumps is a simple yet ingenious component: the hose. By using advanced hose designs, these pumps can significantly increase longevity and decrease operational costs. Let's explore how these innovative pumps are reshaping industrial pumping and driving efficiency across a range of applications.

Proposed Changes To The Risk Management Program (RMP) Rule

The Risk Management Program (RMP) is a law created to protect the greater community from the accidental release of highly hazardous chemicals. Under the Clean Air Act, Section 112(r)(7), there are requirements for the employer to have accident prevention plans for every facet of handling these chemical hazards.

Water Intelligence For Controlled-Environment Agriculture Systems (CEA)

The average U.S. farm spends between $300 and $1,000 per acre on all of the equipment and inputs needed to grow crops in an openfield system. For a vertical farming system, this cost commonly reaches millions of dollars per shelf acre equivalent.

Filtration For World's Largest Recirculating Whitewater River

Understanding How Predictive Analytics Tools Benefit Power Utility Asset Management

The impact of utility industry restructuring is being felt on several levels. The upside of distributed generation growth and the diversification of power sources are also resulting in the downside of loading issues, less switching flexibility and the potential for reverse power flow. New predictive asset analytics tools allow utility personnel to address these issues before they become problems. This paper reviews how these tools can be applied to both utility operations and maintenance.
