Waterco has devised a filter bed of Zeoplus and Garnet able to achieve effective filtration down to 5 microns with the added benefit of Ammonium adsorption.
Superior Filtration plus Ammonium Reduction
Garnet (0.2 - 0.6mm) is the means to very fine filtration. However, a filter bed entirely made up of Garnet (specific gravity 4.0) would result in increased head loss, backwash flow rates and a decreased service run.
Therefore a lighter (specific gravity 2.4) and coarser (1 - 2.2mm) upper layer of Zeoplus is implemented to lower head loss, backwash flow rates and extend the service run.
Waterco conducted the following tests on Zeoplus/ Garnet’s filtration and ammonium adsorption capabilities:
1. Filtration Effectiveness below 5 microns The combination of Zeoplus and Garnet produces a filter bed capable of filtering particles between 5 and 10 microns.
2. Ammonium Adsorption Zeoplus is able to absorb ammonia and this decreases the level of chloramine in the swimming pool leading to: *Reduced chlorine demand, *Reduced skin eye irritations, *Reduced “Chlorine” odour.
Zeoplus/Garnet Percentage Removal at: 20m3 /hr/m2 - recommended filtration velocity for residential and commercial water conditioning. 36m3 /hr/m2 - recommended filtration velocity for commercial pool and spa filtration
