Field-erected evaporative “wet” cooling towers, combined with heat exchangers, are an economical and efficient method to dissipate large heat loads at oil and gas refineries and chemical processing plants – as long as they’re free of harmful debris. Yet many cooling towers at these facilities are highly susceptible to poor performance and costly downtime due to problems associated with debris buildup and potential for debris to pass by traditional stationary water screens during the cleaning process, clogging heat exchangers.
For U.S. Flue-Cured Tobacco Growers, Inc. (USFCTG) sustainability is a guiding practice for tobacco production from seed to delivery. So when traditional chemical water treatment had proven problematic in air washers at its plant in Timberlake, North Carolina, the company thought outside the box for solutions to address a variety of issues while also supporting its sustainability goals.
While most rely on chemicals for water treatment, others are finding success in what can be accurately and fairly described as a green solution because it takes the form of a moss. More precisely, this plant-based alternative to chemical water treatment leverages the properties of sphagnum moss, and it’s being harvested, processed and sold as ProMoss™ to companies throughout North America by Creative Water Solutions (CWS), Plymouth, Minnesota.
Water treatment professionals understand that if applied correctly, solid-form products can be just as effective of a method to protect cooling and heating systems from corrosion and scale as their liquid counterparts. And with the additional sustainability, safety, ease of use, and shipping cost benefits of solids, hundreds of facilities are transitioning to these products each year world-wide.
ElectroCell Systems, Inc., manufactures a system for commercial, industrial and institutional facilities that is applied to conventional water-cooled chilled water plants. The system significantly improves efficiency in water and energy use with paybacks in the 2.0 to 3.5 year range. The system is not a substitute for chemical treatment; rather it is a Condenser Water Efficiency system, engineered specifically and solely to increase water and energy efficiency by addressing the uniquely challenging demands that exist only in the condenser water loop.
