Water Savings

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.

Chiller & Cooling Best Practices Magazine interviewed Peter Armbruster (Director of Sales and Marketing) and Bob Smith (Director of Product Management) at Thermal Care to gain insights into best practices used to accurately evaluate and assess a plant’s cooling needs and ultimately provide the solution best matched to the application. 
This article examines challenges with phosphorous-based programs, key factors to controlling cooling water chemistry and the advantages of phosphorous- and zinc-free cooling water treatment technology.
Chillers are an essential component in many building Heating, Ventilation and Air Conditioning (HVAC) systems. They provide cooling to the building by working in tandem with pumps and cooling towers in a water-cooled chiller plant. Because of the chiller’s complexity and its role in cooling facilities, it is arguably the most important piece of equipment to maintain.
Among key initiatives at DENSO’s Maryville, Tennessee, facility is the use of an innovative ice-storage system engineered to provide environmentally friendly comfort cooling to employees at the company’s main production facility. The system also allows Plant 101 to reduce cooling costs per ton by 44%, while providing a payback of less than four years. It also resulted in an annual carbon dioxide (CO2) reduction of 18,000 tons.
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.
For decades, evaporative cooling has been the principal means to regulate the temperature of buildings. And with more than 50% of total building water usage dedicated to heat transfer, there are major opportunities for water savings.
Data centers are a lynchpin of our modern economy. Server rooms power small- to medium-sized businesses, enterprise data centers support major corporations and server farms host cloud computing services. Keeping up with the explosive growth of digital content, big data, e-commerce and Internet traffic is making data centers one of the fastest growing consumers of electricity in developed countries.
As the population continues to grow in the United States, industrial water use will need to continue to fall to help offset the increases in public-supply water use.  Water-cooled compressed air systems provide an opportunity for sustainability managers to reduce associated cooling water consumption and costs. If switching to air-cooled air compressors is not possible, understanding the costs and the alternative types of liquid cooling systems is important.
The demand for advanced computing power rises year after year, but the more powerful the system, the more heat it generates. As data centers grow, they place higher demands on cooling equipment. Packing as much kilowatt and computer usage into as small a space as possible is key to reducing the cost and size of the facility. In doing this, data centers increase the power density of their systems, drawing more power, and generating more heat per unit area.
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.
