Compare and understand the most common calcium carbonate scale prediction methods for cooling waters. Learn where and why some methods are inaccurate, and understand how an accurate prediction method can optimize a calcium carbonate scale-control program as well as provide a cost reduction in cooling water treatments.

Predicting calcium carbonate scale in water systems has been done for more than 20 years — often with questionable or even inaccurate results rather than actual field observations.
Following an order in 2016, a 1,030 bbl/d bespoke produced-water treatment package was delivered to an integrated oil-and-gas services company in Malaysia. The package was supplied as part of a development project for a sizeable gas block located approximately 50 miles (80 km) off the Malaysian coast.
Foxconn will add a $30 million zero liquid discharge industrial water recycling system at the manufacturing facility under construction in Wisconsin. The company first proposed the ZLD system in its application for to the DNR in January.
As boilers age, they become less efficient, thereby increasing operational costs. Replacing the boiler is the obvious choice; however, it may not be necessary. If the boiler pressure vessel is in good shape, upgrading the burner and controls while adding heat recovery can not only restore a boiler to its original efficiency but probably improve it.
Any industry professional would quickly agree that water is the key ingredient to evaporative cooling system performance. For evaporative cooling equipment like cooling towers, evaporative condensers or fluid coolers, water quality is essential for proper heat transfer and the healthy service life of the equipment.
As fate would have it, the first article I ever worked on for Process Heating related to heat transfer fluids. “Check Your Fluid Before It Checks Production” appeared in our May/June 1995 issue, and it focused on the common tests that are performed on industrial heat transfer fluids to determine whether a fluid changeout was needed in a system.
Industrial water treatment via biocide optimization is among the topics planned for the AWT 2017 Annual Convention and Exposition. The event will be held September 13-16 at the Devos Place and Amway Grand Plaza Hotel in Grand Rapids, Mich.
