APOLLO DISC-KLEEN FILTER OPERATIONS, MAINTENANCE AND TROUBLESHOOTING GUIDE

The discs are stacked on the spine. The discs are color-coded by mesh
size and are selected according to water fi ltration requirements. The spine
assembly has a spring compression unit and an internal piston which are
used to alternately compress and release the discs during fi ltering and
backfl ushing cycles.
FILTRATION MODE:
During the fi ltration process the discs are tightly compressed together by
the spring, forcing the water to fl ow through the grooves and traps the
debris.
BACKFLUSH MODE:
During backfl ush, the discs are separated by the releasing the inlet
hydraulic pressure. Multi-jet nozzles provide peripheral spray on the
loosened discs, causing them to spin, and release the retained solids,
which are fl ushed out through the drain.
WATER QUALITY
•
Good Water Quality:
Municipal water supply
or well water from a clean aquifer with no
sand, iron or manganese.
•
Average Water Quality:
Wells with small
amounts of sand (< 2 ppm) or clean surface
water which includes lakes, ponds,
reservoirs and canals.
•
Poor Water Quality:
Well water from a poor
quality aquifer (> 2 ppm) or surface water
in hot climates with increased biological
growth and no chemical treatment which
includes lakes, ponds, reservoirs and
canals.
•
Very Poor Water Quality:
Well water with
greater than 10 ppm of sand including
rivers, muddy canals, lakes and ponds with
severe run off deposits and raw municipal
wastewater.
•
Greater than 3 ppm Sand or Silt:
May
require a pre-fi lter such as a hydrocyclone.

Calculating Maximum Flow Rate (GPM) per Filter Unit:
Take the total # of Spines based on the fi lter size and multiple
that number by the Flow Per Spine based on the Water Quality
and Mesh.
