Evaporative cooling towers are key components in the effective operation of plants in the electric power, industrial process and manufacturing industries.
Multiple methods of dealing with waste stream discharges are examined in light of the recent clampdown on industrial processes. By Brad Buecker, process specialist, Kiewit Power Engineers
The client was in need of both a raw water and wastewater treatment system for its new 1,100-megawatt (MW) natural gasfired combined cycle power station that was being built to replace an existing 400-MW coal-fired plant that had been decommissioned previously. Veolia Water Technologies was contacted to engineer, procure and supply a 6,000 gallons per minute (GPM) raw water treatment system and a 1,200-GPM wastewater treatment system.
The use of low salinity water in Enhanced Oil Recovery processes has been a recent topic of discussion. The potential to increase recovery rates by altering the reservoir characteristic from an oil-wet to a water-wet state, along with potential cost savings, has garnered attention in recent years.
The South Coast Steam Power Plant, Puerto Rico, decided to replace an old, antiquated ion exchange-based demineralization plant with a membrane-based demineralization system.
In 2010, one of the Power Plants of Puerto Rico Electric Power Authority (PREPA) faced a crisis due to biological growth in their power plant’s cooling tower. The plant was using straight hypochlorite, which was not effective at controlling biological growth.
The Villoresi Channel, located north of Milan, was designed with the main purpose of agricultural irrigation while providing water to the city of Milan. The paths running along the canal were also used for recreational purposes and cross through some of the most beautiful natural parks in Lombardy.
The substitution of conventional biocide treatments with MIOX Mixed Oxidant Solution (MOS) has resulted in a biocidal cooling tower water treatment process that costs less and is more effective than isothiazoline and bromine biocides.
Water’s high heat capacity, high thermal conductivity, and historically low cost make it popular for process heat exchange. Power plants, especially those for liquid cooling applications, withdraw a large fraction of the total demand for water necessary for agriculture, industry, recreation, hygiene, drinking, and wildlife.

To meet China’s growing need for electric power generation, the Guohua Ninghai Power Plant has a total planned operating capacity of 4 x 600 MW [Phase 1]. The plant is located south of Shanghai in Ninghai township, Ningbo city, Zhejiang province and serves the electric power needs in the region.

Whatever the setting, and however contaminated your water, BakerCorp has a solution. That's the message shared by Mehrzad Emanuel (Vice President, Filtration), Doug Herber (Vice President, Water Treatment Technology), and Bruce Lesikar (Director of Engineering) in this video presentation from WEFTEC, where they discuss BakerCorp's electrocoagulation technology and its mobile treatment platform with Water Online Chief Editor Kevin Westerling.
Water from cooling towers attracts and absorbs airborne contaminants on a continuous basis. Typically, 85% of suspended solids in cooling water and hot water loops are smaller than 5 microns. Scientific studies have shown that these small particles (5 microns and less) are the adherent contaminants fouling the water loop and process cooling system.
Founded in 2017, under the consolidation of global water industry leaders Emefcy and RWL Water, Fluence was established with a vision to become the key global provider in decentralized water and wastewater solutions.
O’Brien, Texas is just one of thousands of small communities in the United States that struggle to find the resources to ensure that the water coming out of the tap is safe to drink. The recent budget proposal by the Trump administration will only make matters worse. Watch this documentary short produced by Tom Rosenberg and Earth Institute fellow Madison Condon details one shrinking town’s drinking water crisis.
You can’t control what you don’t know and when it comes to gas mixtures, control is of vital importance. But how can you get a handle on all of the elements you’re processing at a given time?
Unbeknownst to many, coal ash is one of the most prolific industrial wastes affecting wastewater quality in the country, with more than 100 hundred million tons produced each year. And treating for the byproduct is paramount, with health concerns and stringent regulations in place governing its removal.
Utilities are faced with myriad threats looming in the future, but chief among them is increased stress from population growth. In Denver, comprehensive planning for that future is underway.
Amid growing concerns around algal bloom, industrial operations are under pressure to stop using phosphorus-based water treatment technology. But transition to an alternative can be daunting.
India is making great strides to aggressively expand its renewable energy capacity. But the country's power sector remains highly reliant on thermoelectric plants, with high demand for water for cooling. That means that droughts, like the one caused last year by weak monsoons, can shut off the power, hampering the economy and potentially endangering lives.
Resiliency is a hot button word right now. Ten years ago, advocates focused on “adaptation,” or the idea of adapting to the coming effects of climate change. Now the focus is on “resiliency,” the ability to bounce forward — not backward — when something disastrous happens.
We’re entering the home stretch of the 85th Session of the Texas Legislature.
It may sound intimidating, but water that has been treated to “ultrapure” condition is more than necessary in many applications. This highly-cleansed product is a fundamental part of many industrial operations, from the medicine we need to get well to the power we rely on in our daily lives. But, as the name implies, it’s no small task to get average influent to the ultrapure level.
By harvesting heating, ventilation, and air conditioning (HVAC) condensate, industrial operations can take advantage of a cool, convenient source of clean water.
By making strategic choices to maximize energy-water efficiencies, we can help protect our supplies in advance of our next drought. Here are three ways that work.
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?
Deep in the Israeli desert is an academic institute that is building peace in the region by putting nature at its center. The Arava Institute, in partnership with Ben Gurion University, brings students from Israel, Palestine, Jordan, and around the world to find common ground around environmental problems and build trust — and peace — from there.
At my household, a new year means a new energy and water-use baseline. By that I mean, every month, I look at how much electricity and water I used in comparison to the same month the previous year — so I can try to be as efficient as possible. But I work in the energy field, and I know that’s not a typical New Year’s tradition. Most people don’t examine the trends of their energy-use or spend much time thinking about how to reduce it.
After acquiring TELOG last year, Trimble has combined its traditional GIS/GPS navigation technology with TELOG’s remote monitoring solutions to create Trimble Unity, a smart network for monitoring water systems.
