CARTRIDGE CLEANING INSTRUCTIONS

HydroScientific filter cartridges in most applications and micron ratings can be cleaned and reused. We suggest that you clean cartridges when pressure differential is 12-15 psi above the differential pressure at start-up. In the event cartridges are to be replaced, allow the pressure differential to climb to 25-30 psi above the start-up differential or when flow has diminished to an unacceptable level.

Cleaning Instructions –
Cartridge Cleaning in Aqueous Applications

Clean cartridges with a pressure nozzle using standard hose and direct spray at an angle to remove dirt, sand, silt and any other particulate matter.
Please follow these directions for best results:

APPLICATION FOR POTABLE WATER

Refer to www.nsf.org Approved citric acid (NSF Standard 60).

APPLICATION TO REMOVE ORGANIC MATTER AND ALGAE

Use tri-sodium phosphate or similar strong detergent (2 lbs. to 10 gallons of water), 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 cartridge thoroughly with water.

APPLICATION TO REMOVE CALCIUM & MINERAL DEPOSITS

Soak cartridges in a solution of tri-sodium phosphate or similar strong detergent (2 lbs. to 10 gallons of water).

WARNING: DO NOT RINSE CARTRIDGES WITH ACID UNTIL OILS AND ORGANIC MATTER ARE REMOVED. USE DETERGENT FIRST AND FOLLOW WITH ACID SOAK FOR MINERAL REMOVAL. FLUSH CARTRIDGES WITH WATER AFTER MURIATIC OR TRI-SODIUM PHOSPHATE BATHS. GENERALLY, IT IS NOT POSSIBLE TO CLEAN HYDROSCIENTIFIC™ CARTRIDGES WHEN FILTERING PETROLEUM-BASED LIQUIDS AND TOXIC SUBSTANCES. DO NOT CLEAN CARTRIDGES THAT ARE ONE MICRON AND SUB-MICRON CARTRIDGES.
