Applicatons

FILTER COAL H is used as the top layer in dual media filters. It is particularly well suited for swimming-pool water treatment by removal of disinfection byproducts such as chloramines, trihalomethanes and adsorbable organic halogen compounds (AOX). Degradation occurs by adsorption as well as catalytic decomposition on the media's phase interfaces.
