optimized technology, or HOT, can sanitize carbon towers and
control bacteria growth and organic fouling.  by Harry DeLonge
Faced with an increasing need to maintain carbon and carbon
towers in a sanitary condition, the food and beverage industry
requires a consistent, reliable sanitization method, and heat
optimized technology (HOT) helps address this need. Carbon
towers are very efficient in removing chlorine, chloramines and
a wide range of organic contaminants.Yet, they are vulnerable to
bacterial growth and organic fouling, and therefore require
backwashing and periodic sanitization. When fed with surface
waters, they also require steam stripping to remove accumulated
volatiles such as trihalomethanes (THMs).  HOT is a patented
process used for sanitizing carbon towers to control bacterial
growth and organic fouling. By combining the carbon tower’s
backwash and sanitization steps with
