Apollo™ Disc-Kleen Filters

The Apollo Automatic Disc-Kleen Filter has a new modular design that allows you to filter more for less. Apollo filters have been used by growers successfully and reliably for 10 years.


Apollo™ Disc-Kleen Filters

Why Apollo™ Disc-Kleen Filters


The Apollo features a longer filter element (spine) with larger discs (rings) producing a larger filtration area which accommodates a higher flow rate so the total number of filter units is reduced – lowering the filter cost.


Only 30 psi is required for backflushing reducing the need to oversize the pump for adequate flushing and it also reduces the need for a Pressure Sustaining Valve.


The Apollo is lightweight with a small footprint making it portable and easy to move which is ideal for crop rotations and rental units in row crop applications.


Made from high-density synthetic materials, it’s corrosion-proof not just corrosion resistant. Chemical injection upstream of the filter unit will not damage any filter components.

Manual Disc Filters Operation

Apollo Disc-Kleen Filters Operation

Disc filters fall into the category of “depth filtration” filters because they add an additional dimension to the cleaning process. A filter element contains a stack of compressed discs with an overlapping series of grooves that force the debris to move through numerous trap points. This process increases the likelihood of capturing debris. Because of the increase in filtration surface area, the frequency of cleaning drops and cleaning is easier.

The discs are color-coded by mesh size and are selected according to water filtration requirements. The spine assembly has a spring compression unit and an internal piston which are used to alternately compress and release the discs during filtering and backflushing cycles.

Manual Disc Filters Operation
Filtration Mode

Filtration Mode

During the filtration process, the discs are tightly compressed together allowing clean water to pass through the discs and trap debris.

Backflush Mode

Backflush Mode

As debris in a filter increases, the backflush process is initiated. During backflush, the discs separate and jets of clean water spray and spin the discs removing the trapped debris which is then flushed out.

Apollo 3 Minus 1 Filter (3-1)

Apollo 3 Minus 1 Filter (3-1)

It’s a component filter used to make multiple filter configurations larger than a 4 unit system and for upgrading an existing system at a later date when higher flow rates are required. the 3-1 twin unit cannot be used as a stand-alone system.

Easier Access to the Discs

Easier Access to the Discs

The Apollo filter has a polymeric clamp that is lightweight and easy to use. A small wrench is needed to loosen the clamp bolt on each side. Then the clamp slides down the filter cover and the cover can be removed. Maintenance and troubleshooting are quick and simple.

Product Advantages

  • 10″ manifold for all filter sizes means easier installation with less inventoried parts
  • Modular design provides portability for easier field installations and has a smaller footprint
  • Water inlet and outlet versatility because grower chooses what works best for the application
  • Lightweight, easy to use polymeric (plastic) clamps secure the filter cover to the filter body
  • Less overall water used for flushing – shorter overall flush cycle ensures better uniformity of irrigation and less flush water to dispose or filter for reuse
  • Lower installation costs – pre-assembled and ready to install. Flange and bolt kits make assembling multiple filter units easy wth minimal additional installation costs.
  • Smaller footprint – easier and faster to install while saving money on concrete pad size
  • Eliminates leaks and rusting – synthetic materials are not damaged by chemical injection or organic materials in the water and will no corrode


  • Agricultural Irrigation for Permanent and Row Crops
  • Systems Requiring High Volumes of Water


Water Quality Guidelines

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-filter such as a hydrocyclone.
