GENERAL NOTES
These instructions cover the FILOX Range of filters, which includes model
numbers from CF1044 to CF 3072.
It is recommended that these instructions are read thoroughly before commencing
any work on the unit, particularly if you have no previous experience of installing and
using a filter.
3.1
Iron & Manganese Removal
Heavy metallic contaminants, and some non-metallic contaminants can be removed
from water using specific media. These media can be mixed in a multi-layer bed
which, when combined with an appropriate backwash or regeneration system, can be
tailored to solve a wide range of specific contaminant problems.
Iron and manganese and sometimes aluminium and hydrogen sulphide can be
removed with a catalytic filter media, which uses oxygen in the water to convert the
metal ions from the soluble to an insoluble form. The insoluble precipitate is then
filtered out onto the surface of the media. Depending on the composition of the raw
water a choice of media can be used.
Filox filter media is one of these medias and just requires backwashing with the raw
water to clear the bed. The operating parameters for Filox make it suitable for a
number of water types.
3.2
System Management
In order to remove accumulated deposits from the filter bed, the water flow through
the filter is reversed (backwashed). Water is run to drain at a high rate to separate
the filter media from the deposits. The control valve completes the backwash
cycle automatically at the intervals and times set during installation. Backwash and fast
rinse times are set for 16 minutes per cycle but can be altered to suit individual
requirements.
All filter valves have the option of an additional volt free microswitch, which can be
used to initiate a regen pump etc.
