What Are The Differences Between Slat Tray Vs Random Pack Media?

Water ChartThe first step is understanding the chemical analysis of the water you are going to treat. If this is an aeration process for iron (Fe) removal than it is vitally important to understand the concentration, pH, and alkalinity of the water, in addition to the amount of calcium carbonate, or other minerals, that may be present.

For heavy fouling conditions a slat tray media selection can save you both down time and costs. Slat trays provide an anti-fouling benefit based upon the design intended to “shed” particulate as it is formed. They still need to be cleaned in heavy conditions, but far less often and cleaning is easier. If the tower process application is requiring high removal efficiency then loose fill media may be the only choice, unless a pretreatment tower with slat trays is installed in front of the process. Each application must be evaluated on its own merits and reviewed for potential fouling and anticipated operating cost.

Pack MediaLoose fill random pack media, if fouled completely will block water flow and air, and can in some circumstances become so heavy that the weight can damage the internals of a tower. This of course will cause a shutdown and more expenses to remove and repair. Normal service cleanings under a service contract is highly recommended. For more information or to learn more contact the professionals at DeLoach Industries Inc. at (941) 371-4995.
