Power generation need not be another source of strain on diminishing freshwater resources. Well-established water reclamation technologies are enabling producers to conserve resources—and money. Meeting the

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 […]

A variety of approaches have been used to capture new benefits from combined heat and power (CHP) facilities. Some owners have transitioned to new fuels or added renewables to the mix, while others have implemented unique business models to spur development. As district heating systems are brought into the 21st century, the CHP sector seems […]

Compliance with one of the latest federal environmental regulations, the Effluent Limitations Guidelines (ELG), can be both costly and complicated. A newly available option offers features and capabilities that may make it a more attractive alternative than conventional approaches. In September 2015, the U.S. Environmental Protection Agency (EPA) finalized a new rule affecting flue gas […]

The Mátra Power Plant in Visonta, Hungary, uses a dense slurry system for handling fly ash and other coal combustion residuals. The DSS combines ash and water in a 1:1 ratio, creating a cement-like slurry.

According to a Duke University study, future climate warming will likely cause only minor reductions in power output at most U.S. coal- and gas-fired power plants.

To satisfy China’s more stringent water use and air pollution rules, developers of the new 1.3-GW ultrasupercritical coal-fired Changxing Power Plant used a novel forward osmosis–based brine concentration

A severe water crisis gripping India this year has forced several of the country’s hydroelectric and thermal power plants to shut down. At least 10 of India’s 29 states have been stricken by severe drought after the monsoons failed for two seasons in a row (as of the start of July, the monsoons had still […]

When commissioning a new power plant, requirements for purified water can be large—often more than an unfinished plant can supply. When it’s time to bring in outside help, proper planning can help avoid problems and keep budgets under control. With all the complexity inherent in the commissioning of a power plant, the last thing anyone […]

Droughts attributed to the El Niño phenomenon have gripped Venezuela’s neighbor Colombia. Bogotá in April prepared to ration power and instituted mandatory reductions in consumption, warning that
