Fracking Disclosures Show Widespread Use Of Hazardous Chemicals

Fracking, short for hydraulic fracturing, is a process in which workers inject fluids underground under high pressure. The fluids fracture coal beds and shale rock, allowing the gas and oil trapped within the rock to rise to the surface. Advances in fracking launched a huge expansion of U.S. oil and gas production starting in the early 2000s but also triggered intense debate over its health and environmental impacts.

Capacitance Level Switches Provide Reliable Water/Oil Interface Detection

There are a number of point level approaches to measuring the interface between water and oil for water dump control in the oil and gas industry. However, each has disadvantages — manual methods introduce human error, conductivity switches are rendered inaccurate by buildup, and float switches are susceptible to wear and tear. This white paper introduces capacitance level switches as an accurate and reliable alternative for water/oil interface detection.

Can SNOWater Fix Fracking Treatment?

As the popularity of hydraulic fracturing continues to strain available water supplies, a new technology may be the key to recycling produced water in an affordable way.

Wastewater Treatment In Oil Refineries

Refineries are among the major consumers of water that has both process and non-process origins. The average refinery requires 2.5 gallons of water for every gallon of crude oil processed. Depending on the type of crude oil, composition of condensate and treatment processes, the characteristics of refinery wastewater varies widely. The design and operation of modern refinery wastewater treatment plants are challenging and are driven by technology. This article will highlight the most common types of waste streams in a refinery and suitable wastewater treatment strategies.

Forward Osmosis: How It Works, And Why It's Important

Is this innovative desalination technique ready to topple incumbent technologies? An industry expert explains the benefits and potential of forward osmosis.

4 Benefits Of Electrocoagulation For Food And Beverage Wastewater Treatment

With a global population of over seven billion people, there are hundreds, if not thousands, of companies in the world that produce the food and beverages that are needed to meet this global demand. These companies require massive amounts of water to produce their products, and those products result in equal amounts of wastewater. It’s simple enough to just discharge the wastewater into a nearby stream or surface water source and be finished with it. However, with constantly changing environmental regulations and pressure to be more environmentally conscious, food and beverage companies face increasing requirements of beverage and food wastewater treatment.

Flow Meter Ensures A Smooth Running Recovery Process At Bakery Production Plant

Employing roughly 5,000 workers in 12 countries, Vandemoortele bakery and production plant owes its success to high standards of quality, innovative production technologies, and a flair for finding economic alternatives. The latest example is the SITRANS FC430 Coriolis flow meter.

Compact ST75 Thermal Mass Flow Meter Measures Natural Gas, CO2 And Waste Gases In Breweries

The versatile, green-friendly ST75 air/gas flow meter from Fluid Components International (FCI) accurately and reliably measures natural gas, carbon dioxide (CO2), and mixed waste gases in small line sizes to optimize brewing fermentation processes, product quality, and overall plant efficiency.

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.

How To Power Your Treatment Plant And Reduce Costs With Waste-To-Energy Technology

Electricity is a major cost for industry operations, and the cost of meeting environmental regulations is right up there as well. At the same time, industries are compelled to improve sustainability and lower their carbon footprints.

EPA Providing Guidance For Drinking Water After Radiological Emergency

What would happen if there was an emergency in the U.S. that caused radioactive material to contaminate drinking water supplies? What steps could your utilities and government take?

The Long Journey Of An Energy-Water Bill In Texas

Being an environmental advocate in Texas may seem like an uphill battle, and I make no bones about the fact it most certainly is.

Will Water Scarcity Be The Death Of Fossil Fuels?

Water stress, whether caused by drought, access limitation, or contamination, has been increasingly detrimental for an ever-growing range of industries. Recently, a report by CDP, in collaboration with Planet Tracker, shed light on the significant impact of water insecurity on the financial performance of more than 4,000 companies. Of particular note are those companies in energy or energy-adjacent sectors.

Selenium Removal Technologies: A Review

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.

A Roundup Of Energy, Water, And Climate Bills In The 84th Texas Legislative Session

We’ve almost made it to the midway point of the 84^th Session of the Texas Legislature. As many already know, the Texas Legislature only meets from January to May every other year, so a lot has to get done in these few months.

EPA Researchers Develop Method For Studying Agricultural Nutrient Pollution In The Midwest

Nutrient pollution is one of the most pressing issues currently facing U.S. waterways. Nutrient pollution primarily refers to when nitrogen and phosphorus, two elements that occur naturally, have adverse effects on water if they are overabundant. Excess nutrients are a result of runoff from fertilizers, detergents, wastewater, automobile emissions, and more. When these nutrients exceed natural amounts, it can lead to harmful algal blooms and hypoxia, which threaten aquatic biodiversity, as well as human health and industries like commercial fishing.

MBBR System Implements Nitrogen Reduction Plant Improvements

Hopewell Water Renewal (HWR) is a 50 MGD secondary wastewater treatment plant that treats the wastewater from local industries and domestic sources of the Hopewell, VA area. The plant began operating in 1977 and treats approximately 85% industrial waste. The facility achieves the treatment permit requirements for both BOD and TSS; however, treatment regulations have changed over the years and now require the removal of nutrients. HWR discharges effluent into Gravelly Run, a tributary of the James River and Chesapeake Bay Watershed.

EPA Scientists Develop New Methods To Evaluate Chemicals

EPA scientists are developing and evaluating new methods to evaluate chemicals for potential health effects. These methods are fast, cost effective, and reduce our reliance on traditional methods which use laboratory animals.

EPA Researchers Develop A Chemical Category-Based Approach To Prioritize PFAS For Data Collection

The Toxic Substances Control Act (TSCA) requires reporting, record-keeping, testing requirements and restrictions for chemicals of concern, including PFAS. To help meet these requirements, U.S. EPA researchers have developed a chemical category-based approach to help prioritize PFAS for further data collection efforts.
