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…

Research and development in the brewing industry is peaking, driven by efforts to improve quality, efficiency and sustainability Within the chemical process industries (CPI), the brewing industry is among the sectors with the deepest historical roots and the most entrenched…
The industrial uses of onsite-generated ozone are continuously growing. This article outlines applications for ozone in the CPI and discusses the advantages and disadvantages of using this gaseous chemical Ozone is most commonly thought of as the stratospheric barrier to…
Thermal hydrolysis of wastewater sludge before it enters anaerobic digestion units can increase the rate of residuals-to-biogas conversion (biogas production) and increase the feed concentration, the combination of which significantly reduces anaerobic-digester reactor volume. An advanced thermal hydrolysis process (THP)…
