Fractional Electrodeionization (FEDI) Technology For RO Permeate Polishing And Demineralization

Sabine Pass, a large LNG refinery in the U.S., required a membrane desalination solution to cater to its extensive process water needs in order to produce a large amount of liquefied natural gas for export.

Real-Time Heavy Metal Monitoring For Oil & Gas

Large, distributed water networks are not well-suited for conventional water monitoring processes which rely on manual sampling and lab testing. In particular, this midstream oil and gas company had a need to detect Iron, Selenium, and other heavy metals at a precise level comparable to a lab. In addition, it wasn’t feasible to manually test the entire water system at the requisite frequency. Finally, instrument reliability and unplanned downtime were an issue.

Where Is RF Technology For Oil And Gas Headed?

Read for a quick snapshot of the technology movement we are seeing in the oil and gas industry right now.

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.

New Technology Makes Wastewater From Oilsands Safer For Fish

In the northeastern corner of Alberta, nestled among the expanses of forests and wetlands, lies a major freshwater dilemma that Canada is currently facing. The reuse of water for oil extraction causes tailings ponds to accumulate higher and higher concentrations of harmful contaminants. As such, the water in these tailings ponds is dangerous, and often lethal, to birds, fish, frogs, and plants.

DO Or Die — Dealing With Aeration Basin Oxygen Deficiencies

Managing the treatment of wastewater — especially industry-generated wastewater that can elevate dissolved oxygen (DO) demands far beyond those of municipal/residential applications — is hard enough. Trying to do so during upset conditions is enough to put any water treatment professional on edge. Here are several preventive and remedial options to keep in mind before or after DO readings go haywire.

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.

Here's How Wastewater Facilities Could Tackle Food Waste, Generate Energy, And Slash Emissions

Most Australian food waste ends up in landfill. Rotting in the absence of oxygen produces methane, a potent greenhouse gas. While some facilities capture this “landfill gas” to produce energy, or burn it off to release carbon dioxide instead, it’s a major contributor to climate change. Valuable resources such as water and nutrients are also wasted.

Meat-Free Diets Could Cut Our 'Water Footprint' In Half, Say Scientists

Three thousand litres of water — that is the amount needed to produce the food each British person eats every day. This is according to a new study into the “water footprint” of diets in Western Europe, conducted by the European Commission and published in Nature Sustainability.

Alcoholic Beverage Fusel Alcohol Testing With Static Headspace

A static headspace method was developed using Teledyne Tekmar automated headspace vial samplers to meet the method requirements of the Alcohol and Tobacco Tax and Trade Bureau of the US Department of the Treasury (TTB) method SSD: TM:2001 for testing fusel alcohols in alcoholic beverages.

Saving Texas' Water Through Smart Energy Choices In 2016

2015 proved to be another weird weather year around the country, especially for Texas. 80 degrees and dry in Austin on Christmas Day, spring wildflowers in bloom, and kids playing outside in shorts — a surprise ending to a wild ride of drought followed by devastating floods followed by drought and then more floods.

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. 

Why Strategic Choices — And Water — Could Make People More Energy-Efficient

At my household, a new year means a new energy and water-use baseline. By that I mean, every month, I look at how much electricity and water I used in comparison to the same month the previous year — so I can try to be as efficient as possible. But I work in the energy field, and I know that’s not a typical New Year’s tradition. Most people don’t examine the trends of their energy-use or spend much time thinking about how to reduce it.

Activated Sludge Treatment In A Municipal Sewage Treatment Plant

A design/build contractor needed a quiet, efficient aeration system for a 250,000 GPD field erected WWTP that was to be located adjacent to a school. A restriction on ambient noise at the location of the proposed WWTP required a quiet aeration process. Read the full case study to discover how Mazzei solved the problem.

Filtration Media For Municipal, Industrial, And Landscape Water Treatment: Legacy And Novel Technologies

The growing demand for water across a variety of sectors combined with the increasingly understood complexity of emerging contaminants is creating a dynamic marketplace for filtration media. The goal of selecting the right filtration media is not to meet minimum standards but to achieve the right balance of performance, durability, and operational simplicity to ensure long-term compliance and cost-effective operation.

Providing Water And Wastewater Solutions For Our Military

If you want a job done right, you go to a professional — someone who specializes in the task and can make it a priority. Many of us do this when it comes to personal tasks such as oil changes, home repairs and more. The same should be said when it comes to our water systems.

Stepping Up Water Reuse — From Irrigation To Direct-Potable

Water reuse is trending up. Here are nine developments to watch in 2017.

The Payoff From Improved Chemical Dilution

Chemical dilution systems play a critical role in many municipal and industrial water treatment systems. However, older technology tends to be less reliable and accurate while being a drain on resources, whereas a more advanced solution can significantly improve performance and generate labor savings.

A Market On Edge: PVDF's Uncertain Future And The Ceramic Alternative By classifying PVDF as a PFAS “forever chemical” and including it under the proposed restriction, the EU has introduced the prospect of a multi-billion-dollar technology shift. While the outcome will depend on the final derogation periods granted, the proposal creates a defined regulatory horizon for PVDF membranes and forces the global water industry to evaluate alternatives.
