Organic Scavenger Installation, Operation and Maintenance Guide
7.0 Further Installation Notes
7.1 MECHANICAL
7.1.1 Foundation/Drainage
The organic scavenger will not require any special foundations, provided
that a firm, level area which is capable of supporting the working weight is
available.
Unwanted water from the regeneration process must flow to drain, and
so an open drain or gully, capable of passing the necessary flow is
required. The drain may be at a level no higher than 500mm above the
softener valve.
A second drain is required for the brine tank overflow. This is a safety
drain which will only discharge water if there is a malfunction in the
control valve. Where possible this should be installed through an
outside wall like a cistern overflow, where it will give a visual indication
of any failure.
7.1.2 Operating Space
Access will be required to refill the brine tank, and to carry out
adjustments or maintenance on the equipment. It is therefore
recommended that a minimum of 500mm clearance be allowed in front
of the unit for this purpose.
7.1.3 Incoming Water
The raw water to be fed to the organic scavenger must comply with the
following:‐
1. Available at all times at a flow equal to the required service flow
or greater
2. At a pressure between 1.7 and 5.5 bar
3. Temperature between 1 and 40˚C
4. Suspended solids less than 1 ppm
5. Iron less than 0.2 ppm, Manganese less than 0.1 ppm, Free Chlorine less
than 1 ppm if temperature is less than 15˚C, less than 0.3 ppm if
temperature higher (up to 30˚C)
