Corrosion is the nemesis of aquatic facility owners and operators everywhere. In addition to the corrosive effect of chlorine-based chemicals in pool water which can cause aquatic equipment like filters to corrode, corrosive air pollutants (e.g., chloramine vapor, trihalomethanes) in indoor pool environments can also wreak havoc on exposed metals. Plus, the humid, warm, and chlorine-dense atmospheric environment of the mechanical room promotes corrosion.
When building an aquatic system for a commercial or residential project, the multiple types of commercial pool filters available today add a level of complexity to the design process. Should you go with a regenerative media filter or high-rate sand? Is stainless steel or fiberglass a better option? What about cartridge filters or ones that use diatomaceous earth (DE)?
