Optimizing RO-Membrane Performance In Produced-Water Applications

Here are several important considerations for getting maximum value from produced-water RO treatments at minimal total lifecycle costs.

Has Fracking Gone 'Green'?

There are few topics more controversial these days than hydraulic fracturing ("fracking"). While the debate rages on as to whether fracking poses a risk to water quality, a new desalination technique addresses two other environmental concerns: water scarcity and greenhouse gas (GHG) emissions. Developed by researchers at the University of British Columbia (UBC), the breakthrough technology uses excess carbon dioxide created in the fracking process to desalinate the process water, making it available for water reuse. It also generates chemicals — hydrochloric acid and carbonate salts — that are valuable for many industrial applications.

Thermal Flare Gas Flow Meter Solves Measurement Challenges On FPSO Vessels

The accurate measurement and disposal of flare gases aboard floating production storage and offloading (FPSO) vessels is essential to manage these potentially hazardous combustible, flammable and toxic gases. Accurate measurement of these waste gases allows them to be processed efficiently and effectively to protect people and equipment aboard the vessel. Measuring of flare gas is also most often a strict regulatory requirement, as it can form the basis for payment of environmental taxes, climate quotas, etc.

Advances In Flowmeter Technology

This article disucsses two trends turning the flowmeter industry on its ear: advances in flowmeter diagnostics and the adoption of smartphone-like technology to improve access and communications.

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.

How Food And Beverage Companies Can Get Ahead Of The Water Scarcity Curve

High-quality water is critical to food and beverage production — both as an ingredient and a process enabler — so the sourcing challenges faced by municipal water systems pose an ongoing threat to the health of the industry. Fortunately, there are a variety of technology options now available to improve water security.

Dechlorination For The Food & Beverage Industry

For food & beverage manufacturers, product safety is paramount. Minimizing water consumption and improving product ratio & energy savings, which reduce carbon footprint, are also key goals of sustainable F&B operation.

Beware Of Problematic Wastewater Aeration Additives

Too much of a good thing can create new problems as quickly as it resolves old ones. Maintaining a proper balance of antifoaming agents and polymer additives is critical for sustaining the appropriate air bubble size and distribution needed to achieve dissolved oxygen (DO) requirements for neutralizing high biochemical oxygen demand (BOD) in many industrial and food processing wastewater applications.

Methods For Making Ultrapure Water

To break down the treatment options here are three popular ultrapure treatment processes from leading technology suppliers.

Boiler Feed Water Pump Local Instrumentation — Necessity Or Nuisance?

Anyone remember the old cars of the 1950s and 1960s? They all pretty much came equipped with an ammeter, an oil pressure gauge, a water temperature gauge, as well as a speedometer and a fuel level gauge. 

The Energy Reality Behind Cape Town's Water Crisis — And Why The U.S. Should Care

In Cape Town, South Africa, the countdown is on for Day Zero when water taps in the city of 4 million people are expected to run dry.

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.

Looking Back, Looking Ahead: Getting Answers To Evolving Water Issues A review of the WEFTEC tradeshow, current and emerging water threats, and the latest water and wastewater solutions from the VP of a fast-rising treatment provider.

Determination Of Polar Pesticide Residues In Food Of Plant Origin, By And Automate QuPPe Solution

The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.

How Is California Affected By The Clean Water Act Mess?

Just when we thought the jurisdictional and regulatory issues concerning the federal Clean Water Act and the resulting implications could not get more complicated, recent developments have put that possibility to rest.

Pulsafeeder’s Eclipse pumps provide successful chemical dosing at the Middlesex Water Company in Highland Park, New Jersey.

High Density Sludge Process Recovers >95% Of Water

Atlantic Richfield/Montana Resources are responsible for ensuring that the acidic water of the Berkley Pit, the largest landmark and legacy of the Butte, Montana mining days, does not spill over into the nearby Clark Fork River. Veolia Water Technologies worked together with Atlantic Richfield/Montana Resources and the U.S. EPA to develop the treatment system for the mining pit waters.

Unlocking The Potential Of Digital Pressure Transmitters Traditional analog devices are increasingly being replaced by digital solutions, and communication protocols like CANopen are playing a key role in this transition. This shift calls for engineers to assess whether digital pressure transmitters are the best fit for their specific applications.

Is Water Shortage The Next Big Short?

At the end of The Big Short, a postscript stated that one of the story's protagonists, Dr. Michael Burry (played by Christian Bale), was now focused on investing in only one commodity: water. That got my attention.

Farmers Can Save Water With Wireless Technologies, But There Are Challenges — Like Transmitting Data Through Mud

The Internet of Things is a network of objects equipped with sensors so they can receive and transmit data via the internet.
