Selenium, a contaminant of concern in industries such as mining, oil refining, and power generation, is removed from wastewater principally through either biological or chemical/physical processes. This article will describe those technologies, several technology providers, and other sources of information.

Petrogas LLP, one of the world’s largest oil rehabilitation companies, required demineralized water for a new boiler component to its Turkmenistan refinery.

Questions about if and how hydraulic fracturing activities can contaminate drinking water have been top-of-mind for many since the practice started getting widespread public attention about a decade ago. Recognizing the validity of those concerns, EPA undertook a study to see how the full ‘hydraulic fracturing water cycle’ could potentially impact our drinking water resources.

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.

A new report from the Oklahoma Water Resources Board’s Produced Water Working Group indicates that oil and gas companies looking for ways to dispose of large volumes of wastewater should focus on recycling those liquids within the oil and gas fields, and not use it for irrigation or other surface applications where human and environmental exposure is a risk.

In addition to penalties for non-compliance, wastewater treatment plant (WWTP) operators in the food and beverage industry risk excessive losses caused by problems at the wastewater treatment facility.

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.

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.

From the parlor to the pasture, numerous advancements in dairy farm management are helping drive up dairy farm efficiency in North America, and that’s helping drive down environmental impact.

Dairy Crest Davidshow Creamery in Camelford, England is the largest cheddar cheese manufacturer in the UK.

The power sector looks to zero liquid discharge and taps municipal reclaimed water as a water reuse strategy.

This article is the first of two in a Women’s History Month series that showcases a handful of the National Renewable Energy Laboratory’s (NREL's) outstanding women researchers in water power.

By harvesting heating, ventilation, and air conditioning (HVAC) condensate, industrial operations can take advantage of a cool, convenient source of clean water.

The EPA has proposed a regulation  that, if passed,  would set the first federal limits on the levels of toxic metals in wastewater discharged from power plants in over three decades. 

Talking to a friend a couple of weeks ago, the malaprop "canary in the gold mine" popped into the conversation. That was worth a chuckle, but then a moment of reflection. What a perfect way to describe California, nicknamed The Golden State by eager miners during the Gold Rush of the 1840s and '50s, that has been yielding a steady stream of riches from its farms, forests, mines, and minds ever since.
