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 20 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.

The backwash process consists of two stages:-
Backwash - Water flows upwards through the media bed, and out to a drain.
As it does so it separates the deposits from the filter media and cleans off any
particles of dirt or pipework corrosion products, which may have accumulated
during the service cycle.
Fast Rinse - This follows the backwash cycle and entails rinsing away any
residual deposits from the media and re-packing the media bed. This is
carried out down flow with water flowing through the media in the direction of
service.

Most filter application systems are supplied with a time clock
configuration valve, which initiate regeneration at a pre-set time (usually
2:00 AM) after a pre-set number of days. The frequency of regenerations is
fully adjustable, but a minimum of once every 3 days is recommended.

5.1.1 Foundation/Drainage
The filter will not require any special foundations, provided that a firm, level
area, which is capable of supporting the working weight, is available. (See
Engineering Data, Section 11.2)
Unwanted water from the backwash process must flow to drain, and so an
open drain or gully, capable of passing the necessary flow is required (see
Process and Operating Data, 11.1, for relevant flows). The total flow of
