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.

Sun-Activated LilyPads Remove Contaminants Without Chemicals

Puralytics LilyPads are hardly noticeable in the ponds, lakes, and catchment areas where they are deployed. Made of mesh and plastic, the flat, 1-meter diameter disks could even be confused for their plant namesake if not for their white color.

Connected Oil Fields In Peru

In May 2017, China National Petroleum Corporation announced it would invest $2 billion in an oil and natural gas block in the southern part of Peru.

New Technologies Set To 'Disrupt' The Industry

For the unfamiliar, the term “disruptive technology” initially sounds quite bad, as though it describes something that gets in the way. Far from impeding progress, however, disruptive technologies actually accelerate progress exponentially by disrupting the status quo. Think personal computers vs. mainframes, or cell phones vs. land lines.

Doublethink In The Desert: The Myth Of Recycling In The Permian Basin

Everyone is familiar with the water cut statistics: three to seven barrels of produced water emerge from the ground per barrel of oil. This oft-cited statistic is useful to appreciate the scale of the volumes of water produced in the Permian Basin. However, it does not tell the whole story.

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

3 Innovative Ways PepsiCo Is Implementing Circular Water Systems The pervasive and increasing incidence of water stress could perhaps be the most clear-cut consequence of climate change. As weather patterns become increasingly erratic and destructive, floods and drought are continuing to deplete water resources. We're no longer seeing predictable rainy and dry seasons to balance water tables. Couple this with growing and migrating populations that create an ever-increasing water demand, and the result is the undeniable water stress we're seeing globally.

Brewery Reuses Water For Factory Wash-Down

Looking to reduce its water footprint, Shepherd Neame Brewery invested in a complete membrane bioreactor (MBR) wastewater recovery and re-use plant. Learn how the new plant's aeration system has helped to reduce the brewery's water-to-beer ratio to an industry-leading value of 3:1.

Challenges And Solutions To Treating Beverage Wastewater

Discover how one beverage manufacturer was able to balance producing a quality product while also undertaking the challenging of reclaiming and treating its effluent.

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.

Ultrasonic Flowmeter And Solar GSM Datalogger Deliver Continuous Monitoring And Compliance For Hydroelectric Plant In Türkiye

A hydroelectric power plant in Türkiye needed to establish a system for real-time monitoring of water consumption and turbine performance to enhance its operational efficiency. Crucially, the State Water Authority also required continuous, 24/7 remote access to water usage data for supervisory and regulatory compliance.

Cooling Tower Crisis: How Hydrogen Peroxide Scrubbed Away The Bacteria Buildup

A West coast power plant needed an immediate solution to clean its cooling tower that was fast, cost effective, and did not require removal and manual cleaning of the tower's fill material. 

Global Crisis And Modern Solutions At The Water-Energy Nexus

GE Water & Process Technologies and the World Resources Institute (WRI), an independent research organization studying sustainability, jointly produced a white paper called “Water-Energy Nexus: Business Risks and Rewards.” The paper hones in on the shared interest of the two groups, namely the supply of freshwater counted on by the energy industry, which in turn fuels water treatment operations, a relationship that’s known as the “water-energy nexus.”

Waste Heat Recovery For Desalination From Steam Power Plants

Currently, in the Kingdom of Saudi Arabia about 1.5 million barrels of oil are consumed daily to generate electricity to drive reverse osmosis desalination plants.  This represents about 15 percent of KSA’s daily oil production.

Size Matters At EPA

Despite being shorthanded and missing goals, the EPA hasn’t slowed its ambition. In fact, the agency is taking on more responsibilities.

High-Capacity Filtration Plus Ultraviolet Disinfection For Cooling Towers Means More “Uptime” For Server Farms

Most of us use computers or smartphones on a daily basis. But we usually don’t know what goes on behind the scenes — the technology that allows us to use cloud computing or even Google search. And we certainly aren’t aware of the infrastructure needed to support that technology — like cooling towers.

Cost-Effective Telemetry For Agricultural Applications

Implementing telemetry — the ability to transmit flow meter readings — allows water managers in irrigation districts and small rural systems to work smarter, not harder, by aggregating critical, real-time flow information. Until recently, telemetry was expensive and plagued with problems. However, advanced technology offers an ideal solution.

Evaluating The Advantages Of Decentralized MBR Wastewater Treatment

Much of the progress on wastewater effluent quality under the Clean Water Act has focused on centralized facilities in larger cities. Now, decentralized systems are expanding options for municipalities, developers, and engineers to support high-quality wastewater treatment in locales that can’t sustain conventional septic systems or make it too costly to build or access centralized wastewater treatment plant (WWTP) or water reuse facilities.

Aire-O₂ Triton® TR Series Combined With Diffused Aeration Improves Chemical Effluent Quality

Daurala Organics Limited, a chemical producer in Daurala, India, managers 2780m³/d flow in their activated sludge process plant.

Total Systems Approach To Wastewater Treatment

The total systems approach (TSA) to wastewater treatment is focused on offering industrial clients a fully integrated wastewater solution — one that includes all pieces of the puzzle, rather than simply a set of uncoordinated components and systems.
