WATER FILTER MEDIA
WATER FILTER MEDIA
FILTER AG+
Filter AG+ is a superior filtration media to standard Filter AG. It is designed to lower the levels of
turbidity in water even further. It will filter down to a nominal 3 microns and remove smaller particles
of turbidity. On borehole applications, we recommended using a Filter AG+ unit to protect against
dumps of turbidity, even if none is present on the water analysis.
The media traps the particles of turbidity in its filter bed. The total surface area of the bed within the
vessel will dictate the peak flow rate of the unit. Bed depth is only required for capacity, not flow rate.
Trapped turbidity particles are then released when the water flow is inverted, lifting the filter bed and
backwashing to drain through a control valve. It is important to take this into account when specifying
a system, as for it to continue to work for the lifespan of the media, there will need to be adequate
backwash flow and pressure.
Filter AG+ is ideal for turbidity removal and pre UV filtration on larger units, as it can remove particles
less than 5 micron, that prevent shadowing in the UV chamber.

PYROLOX PLUS
Pyrolox Plus is a washed manganese dioxide, similar in properties to Filox. Primarily used for iron
removal it will also remove some manganese as a by-product of the iron removal.
Pyrolox Plus allows a higher service flow rate than normal Pyrolox and has been sieved to a higher
level so needs less backwashing when commissioning.
If pH is elevated to a raised level then the effectiveness of the media is improved. Iron is trapped in
the dense manganese dioxide filter bed due to the size of the iron molecules. Thus, not allowing it to
go to service. However due to the density of the media, backwash flow rates are extremely high, and
need to be taken into account when specifying systems. It is usually more beneficial to run two
smaller pyrolox systems in parallel than one large one due to backwash requirements.
