The Road to "Better Than 90% Treatment Efficacy"

The Road to "Better Than 90% Treatment Efficacy"

Improving Air and Water Quality Track

Because water quality is the sole source of poor air quality at indoor facilities, the control of volatile waterborne contamination needs to be part of any discussion about unhealthy quality. Both waterborne and airborne THM and nitrogen trichloride are known to have adverse effects on patrons, staff, equipment and the building envelope. Therefore, the benchmarks for both water and air quality should be addressed in a more pragmatic way by comparing certain parameters. This presentation will present options for minimizing waterborne contamination levels and hence airborne levels.

Most water treatment processes in US aquatic facilities fall short. Proven process steps like coagulation, flocculation and filtration optimization have been widely neglected as key technologies for improving pool and spa water quality while the focus has been mostly on disinfection, which may work poorly when filtrate quality is compromised. This presentation aims to provide water treatment guidance for owners, operators, engineers, designers and other stake holders in the aquatics industry to raise the expectations when building or redesigning aquatic facilities.
