Greener chemistries and equipment advances provide more sustainable water-treatment options for chemical processors Chemical processors face tough challenges when it comes to the water used in the facility — namely, water scarcity and ever-increasing regulatory requirements associated with discharging effluent.…
Due to the scarcity of global water resources and the ever increasing need to protect the environment, zero-liquid discharge is becoming more and more important. ANDRITZ was active in this field long before “ZLD” became the buzzword it is today.…
The National Alliance for Water Innovation (www.nawihub.org), a partnership of the Department of Energy’s Oak Ridge National Laboratory (ORNL; Oak Ridge, Tenn.; www.ornl.gov), Lawrence Berkeley National Laboratory (Berkeley Lab; Berkeley, Calif.; www.lbl.gov), the National Renewable Energy Laboratory (NREL; Golden, Colo.;…

The threat of water scarcity may not be a top concern for those who have readily available freshwater to meet their daily needs. But for about two billion people who currently live in areas experiencing high water stress and the…
Online monitoring of steam and water chemistry in a steam system is important for safe and reliable operation of steam generators High-pressure, high-temperature steam is a critical commodity at power plants and at many chemical process industries (CPI) facilities. Examples…
In the last two years, SNF Group (Andrezieux, France; www.snf.com) has added 75,000 metric tons per year (m.t./yr) of powder-grade polyacrylamide (PAM) production capacity globally to match the increased demand for EOR (enhanced oil recovery) applications. By the end of…
Water-treatment programs for cooling towers have evolved in recent years, favoring non-phosphorus programs today. This article reviews the impact on water chemistry and operating reliability Cooling towers are a critical component of many industrial facilities. Cooling towers evaporate only pure…
The NSF International (Ann Arbor, Mich.; www.nsf.org) joint committee of stakeholders that maintains the American National Standards for drinking water treatment and reverse osmosis (RO) devices recently updated two standards to include test methods and other requirements for the reduction…
Many desalination technologies have been developed, but they usually require a large amount of energy. Forward osmosis (FO) has the potential to become an excellent alternative desalination technology due to its lower energy consumption. Nano structured materials have also attracted…
