Anthracite-based filter media in accordance with EN 12907
EVERZIT® Special PLUS is a thermally treated filter media based on anthracite coal. It was developed primarily for treatment of swimming pool water by removal of disinfection byproducts such as chloramines, trihalomethanes and adsorbable organic halogen compounds (AOX).
EVERZIT® Special PLUS is used as the top layer in dual media filters.
The hydraulic properties of EVERZIT® Special PLUS are virtually identical to those of EVERZIT® N (Type I) which has been successfully used in filtration for decades.
Therefore the existing filter can normally be used for EVERZIT® Special PLUS without need for modification. Degradation of the disinfection byproducts occurs by adsorption as well as catalytic decomposition on phase interfaces in the media.
