Diamond Electrode Wastewater Treatment Shines Bright

No business wants the word "toxic" associated with its operations. The world has grown very weary (and wary) of companies that aren't environmentally responsible. So while toxic wastewater as a byproduct of mining, oil refining, or other industrial processes isn't new, the impetus to treat these streams is steadily rising.

Blowback From Flowback: Push For Groundwater Alternatives

About 50 percent of the nation’s residents source their fresh water supply from groundwater wells, which have deteriorated throughout the U.S. over the past decade. For shallow wells, severe drought conditions have gradually depleted groundwater levels.

EPA's Water Report: A Good But Incomplete Start

One study cannot answer every question about water pollution risks from oil and gas drilling, nor should it be expected to. But as my colleague Nichole Saunders pointed out, the oft-quoted statement of EPA’s water study – that it found no evidence of “widespread, systemic impacts on drinking water sources”– implied to some that activities related to hydraulic fracturing had been declared risk-free.

Report Identifies Ways To Reduce Water Contamination From Oil And Gas Development In Texas

A new report from the Academy of Medicine, Engineering and Science of Texas (TAMEST) is shedding more light on what we know and don’t know about the potential health and environmental impacts caused by oil and gas development in Texas.

10 Produced Water Treatment Technologies: Evaluating The Pros And Cons

As the oil industry grows, so does the amount of produced water that must be treated. A variety of technologies are available for produced water treatment. Water Online shares a side-by-side comparison. 

Wastewater Disinfection And Energy Generation Make 'Hot' Couple

When the Pasteurization Technology Group (PTG) first presented their heat-based wastewater disinfection system to a group of environmental engineers, they didn’t get the response they expected.

Methods To Control Odors From Anaerobic Digester Plants And Prevent Nuisance To Nearby Communities

Anaerobic digestion is a practical and efficient technology to utilize considerable amounts of organic waste from intensive animal production and food processing and wastage during distribution/consumption, municipal waste, etc. to produce methane gas for electricity generation, local/process heating, and direct injection into the gas supply network.

99-Percent-Efficient Plant Shows Food, Beverage, And Agribusiness How To Recycle Wastewater And Profit From Green Energy

An outstandingly efficient industrial wastewater treatment plant using technology being introduced to Australasia is demonstrating to the food, beverage, and agribusiness processing industries how to turn waste into profit.

Make The Most Of Food And Beverage Effluent

As focus on resource recovery intensifies, food and beverage operations are under a particularly large microscope. An anaerobic digester designed for the food and beverage industry can create value out of the space’s unique wastewater.

Supplemental Aeration System Reduces High BOD Levels And Solves Odor Issues

A leading fruit juice company had expanded over the past ten years and increased wastewater flow from 7,000 to 11,000 gallons per day (gpd), without upgrading its wastewater treatment plant. Read the full case study to learn how after a Mazzei AirJection system was installed, dissolved oxygen levels increased in the aeration basins, which immediately eliminated the odors.

FGD Purge Treatment In Coal-Fired Power Generation

Stricter environmental policies and regulations worldwide are changing how industry approaches all aspects of business. Likewise, EU (European Union) environmental policies governing air, soil, and water quality have become progressively stringent.

These policy changes affect the power industry’s balance of meeting growing European energy demands with compliance to environmental standards. In order to conform with EU standards specific for flue gas, a coalfired generation plant (at the time owned by Endesa, Italia, S.p.A.) in Monfalcone, Italy, undertook the measure of installing a state-of-the-art FGD (flue gas desulfurization) system at their facility. This system would remove SO2 (sulfur dioxide) from the emissions for the 336 MW coal-fired power station.

How Energy Choices Influence Water Quality

Using earth-friendly energy and conserving water supports the fight against climate change and preserves our freshwater reserves.

Natural Gas-Fired Combined Cycle Power Plant Improves The Performance Of Water Treatment System

A natural gas-fired combined cycle power generation facility located in Idaho contacted QUA to find a solution to improve the performance of a water treatment system used to recycle the plant’s cooling tower blow down water.

Water Is Energy

More than 2,000 years ago, Greek and Roman engineers harnessed the power of water to drive grain mills, and the technology soon spread as far as China, where it was used to forge iron. By the 4th century, the Romans had scaled up water wheel technology to build a massive flour plant in Arles, France, powered by 16 overshot water wheels. During the Renaissance, Leonardo da Vinci sketched out visions of water-driven sawmills, forges, factories, and spinning works.

Filtration System For Thermoelectric Plant

AES Gener is the second generating company in Chile and the main thermoelectric generator, and provides 4.068 MW (including Guacolda S.A.), equivalent to a share of 22%, whereas 3.797 MW of thermoelectric capacity and 271 MW of hydroelectric capacity.

Retail Strategy: A New Focus On Hazardous Waste Regulations

America’s hazardous waste management program ensures the safe management of hazardous waste from the “cradle to the grave”. Many of these regulations were developed more than three decades ago, so it is important we ensure they continue to effectively protect human health and environment into the future.

Textile Manufacturing

The textile manufacturing industry encompasses many and diverse processes that rely heavily on the use of water, energy, chemicals, and other resources. Wet spinning, sizing, desizing, scouring, bleaching, mercerization, dyeing and printing are just a few. Monitoring and controlling the pH, TDS/Conductivity/Salt Concentration, ORP (REDOX), and Temperature of the aqueous solutions used in these processes conserves costly resources, controls quality, and reduces the amount of pollution that must be treated before discharge of effluent wastes. This can be done manually with handheld instruments or automatically with in-line monitor/controllers.

Water Reuse Within Reach: Guidance For Potential Practitioners

“Water Champion” Paula Kehoe looks to do for the nation what she did for San Francisco — to greatly expand water reuse opportunities and implementation. In this Q&A, she discusses her new role as chair of a national commission for onsite non-potable reuse, the San Francisco model, and the best practices and obstacles for sustainable water operations.

Sackett v. EPA: A Collection Of Commentary The Supreme Court recently passed down its latest verdict regarding what constitutes "waters of the United States" (WOTUS) and therefore what waterbodies the U.S. EPA has — or, more to the point, does not have — the authority to regulate. Here, I've collected various sets of commentary and reaction about Sackett v. EPA and the impact of the court's decision.

New Methods Extend Options For NPDES Compliance Testing

The National Pollutant Discharge Elimination System (NPDES), introduced as part of the 1972 Clean Water Act, has continued to evolve as new challenges and new technologies emerge. Its latest update, due to go into effect on July 19, 2021, expands the analytical test methods available to governing bodies, industries, and municipalities for compliance reporting under the NPDES permit program. Here is what that entails.
