LIQUITECH FOM is
a highly porous permanent filter granulate with an active
AOP-coating, which acts oxidizing and catalytic on all substances
entrained in the water.
AOP (advanced oxidizing processes) means that even solutes such as the heavy metals lead, copper and
zinc, as well as iron, manganese, arsenic, etc. are converted into
solids. Under certain conditions, even toxic organic compounds
such as phenols, pesticides, solvents, diluents, oils, alcohols etc.
can be digested and removed. In addition, all microorganisms such as
bacteria, algae and
fungi, are eliminated by the strong oxidizing effect of the surface
coating. With a filtration fineness of 2-3 microns (compared to about
50 microns with filter sand), these impurities are filtered as well as
all other suspended matter, and very high filtration rates of 95-99%
are achieved over the entire pH range.
The oxidizing effect of the material is refreshed in each backwashing
by adding PROTABS OXY in the rinse water, thus remaining unspoiled
throughout the whole service life of the filter granulate.
