Stuart Humphries, Orthos Director of Filtration Technology, dissects a 13-slide presentation by Xylem-Leopold containing a multitude of misinformation and other misleading content against nozzle-based, reinforced-concrete, monolithic underdrain filter systems.
Be sure to check out the other blogs mentioned in this video including “Orthos vs Leopold” in which Orthos goes head to head with Leopold for a job in Shelbyville, Kentucky.
In this exchange with valued Orthos representative Tarn Victor of JBI Water, Humphries counters the false content with:
Accurate design methodology
Valid technical reasoning
Performance data
Installation videos, pictures, and graphics
ORTHOS believes in delivering a filter system that will last 100 years, not 10-20 (if you can get that far with plastic block underdrains).
LIFE CYCLE COST WINNER, EVERY TIME
Remember Orthos’ HUGE life cycle cost benefits — At the end of the filter’s life cycle (~25 years), in contrast to a complete plastic block underdrain overhaul, nozzles are simply replaced as the monolithic floor remains part of the civil structure.
