reduce filtration costs. For best results, direct spray into pleats to
dislodge sediment. Alternatively, allow the cartridge to dry and brush
off filter cake from the surface of the media.

15.3 Cleaning
Clean cartridges with pressure nozzle using standard hose. Direct spray at an angle to remove
particulate. Follow these directions for best results:
Oils in aqueous solutions:
Soak cartridges in a solution of tri-sodium phosphate or similar
strong detergent (2 lbs. to 10 gallons of water). Soak up to 12 hours. Rinse after soaking.
Organic matter and algae in aqueous solution:
Use tri-sodium phosphate or similar strong
detergent as described above, plus 1 pint of liquid chlorine to kill organic matter and algae. Soak
cartridges 1 hour or longer until surface is no longer slippery. Rinse after soaking.
Calcium & mineral deposits:
Follow directions for oils described above. Rinse cartridges
thoroughly for approximately 10 minutes in a solution of one part muriatic acid to 20 parts of
water. Rinse cartridge thoroughly with water.
CAUTION
Remove all oils and organic matter with detergent before rinsing cartridges with acid soak for
mineral removal. Flush cartridges with water after muriatic or tri-sodium phosphate baths.
Generally, it is not possible to clean cartridges filtering petroleum-based liquids, toxic
substances and when using one micron and sub-micron cartridges.
