In an unprecedented move, the U.S. Environmental Protection Agency (EPA) on April 25 simultaneously finalized four major environmental rules covering greenhouse gases (GHG), air toxics, wastewater discharges, and coal combustion residuals from fossil fuel-fired power plants. Among the rules is the EPA’s final Carbon Pollution Standards, which marks the agency’s third attempt to broadly curb […]

The Environmental Protection Agency (EPA) is proposing more stringent discharge standards for three types of coal power plant wastewater as part of an update to its Effluent Limitations Guidelines (ELGs). However, the agency also proposed compliance flexibilities, and in a separate direct final rule, moved to extend a deadline to allow more coal plants to […]

More projects to increase the supply of renewable natural gas (RNG) have been announced in Florida and South Dakota, as investments continue in technologies to produce a low-carbon fuel that could replace diesel and other fossil fuels. OPAL Fuels, headquartered in White Plains, New York, on Jan. 5 announced it has completed the ramp-up period […]

The Biden administration has rolled out in a final what it says is a “durable” definition of “waters of the U.S.” (WOTUS), potentially capping a legal and political battle that has raged for nearly two decades. The final rule issued by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of the Army on […]

The rise and rapid adoption of the circular economy—a systems solution framework that seeks to keep materials, products, and services in circulation for as long as possible—is triggering an interesting

Vancouver, B.C, Canada (May 3, 2022) – SHARC International Systems Inc. (CSE: SHRC) (FSE: IWIA) (OTCQB: INTWF) (“SHARC Energy” or the “Company”), a world leader in energy transfer with wastewater, is pleased to announce that the Company has received a purchase order from California | Columbia Hydronics Corporation (“CHC”), a representative of SHARC products in Alaska, Washington, Oregon, Northern California (north of San Luis […]

The Environmental Protection Agency (EPA) is set to establish more stringent standards on water pollution from coal-fired power plants. The EPA on July 26 announced it would reinstate Obama-era regulations that were rolled back by the Trump administration. An EPA official on Monday said the new rule would impact about 100 coal-fired plants. The agency […]

POWER’s 2020 Water Award goes to Saltworks Technologies for successfully piloting a novel application of a 50-year-old technology at a coal plant. The company’s solution promises to slash costs of treating

The liquid filtration process is an important step in various applications that reuse water within systems. This article provides details on the types of filtration systems available and the benefits of each

The Environmental Protection Agency (EPA) has issued long-awaited proposed revisions of two 2015 Obama-era rules that apply to effluent limitations guidelines (ELGs) for steam electric power plants and coal combustion residuals (CCR) management by electric utilities.  The agency coordinated the release of the two related revisions, which apply overwhelmingly to coal-fired steam power plants, after […]

LINDEN, NJ and FRANKLIN, TN – (October 17, 2019) – Aries Clean Energy was joined by local officials and dignitaries to break ground on New Jersey’s first biosolids-only gasification facility on Tuesday. The Aries Linden Biosolids Gasification Facility will bring environmental and sustainable benefits to the area by processing 430 tons of biosolids daily into […]

An innovative nuclear wastewater treatment approach that could provide a cost-effective alternative to fixed-column ion-exchange plants is poised to enter the nuclear market. Atkins, a company that

In a legal victory for environmental groups, a federal court has vacated key portions of the Environmental Protection Agency’s (EPA’s) November 2015-promulgated effluent limitations guidelines (ELGs) for steam electric power plants, deeming them “unlawful.”  The decision adds a dramatic new element of uncertainty in timing of the rule, which the Trump administration has said it […]

A new system to remove dissolved (ionic) mercury, along with other contaminants, from power plant wastewater is being developed. It is free of the drawbacks of using a traditional stannous chloride reagent

The Environmental Protection Agency (EPA) has issued an official timeline for rulemaking that would potentially revise the Obama administration’s 2015 effluent limitations guidelines and standards (ELGs) for steam electric power plants. In its May 2-released Final 2016 Effluent Guidelines Program Plan, the EPA said it will potentially revise the stringent Best Available Technology (BAT) effluent […]

Regulatory uncertainty, changing resources, and an industrywide drive to cut costs and boost flexibility and efficiency are among a growing list of challenges that are prompting new approaches to treat power

As water demand soars in every corner of the world amid widespread drought and water scarcity concerns, recovery and recycling of wastewater is increasingly becoming a valuable solution to alleviate pressures

Many informative articles have been published about options for treating flue gas desulfurization wastewater, but new technologies are rapidly changing the treatment possibilities. This article reviews key economic considerations and introduces an innovative treatment solution that lowers costs and the amount of waste generated. Flue gas desulfurization (FGD) wastewater varies widely depending on the source […]

Meeting the requirements of the Effluent Limitations Guidelines (ELG) means careful consideration of the various options. Both biological treatment and zero liquid discharge (ZLD) approaches have their place, but ZLD may offer more flexibility for the future. On September 30, 2015, the Environmental Protection Agency (EPA) issued the final effluent limitation guidelines (ELGs) rule for […]

NRG Energy will pay $1 million in penalties, install environmental projects worth another $1 million, and complete costly upgrades under a consent decree it entered into with the state of Maryland to resolve wastewater discharge violations at two coal-fired power plants owned by its subsidiary GenOn. The settlement results from a June 2013 complaint Maryland […]
