Zeolite-61 (P/N HC10003) is a high purity natural zeolite. The surface area of Zeolite-61 is 100-times greater than
sand/anthracite thus allowing smaller particles to be trapped. Its larger surface area greatly improves water
clarity and increases the time between backwashes. This product is Certified to NSF/ANSI Standard 61.
BENEFITS
• Safe, natural, nontoxic, inexpensive replacement for
sand/anthracite and multimedia beds
• High surface area holds up to 55% its weight in
water and up to 2.1% nitrogen
• High potassium and low sodium content
• Long filter bed life (approx. 10 years)
• Reduced backwash time and frequency
• Certified to NSF/ANSI Standard 61
• Certified to NSF/ANSI Standard 372
APPLICATIONS
• Bottle water and drinking water plants
• Economical pre-filter for RO systems
• Well water and industrial wastewater filtration
• Cooling tower, chillers, heat exchanger water

Physical filtration barriers for accumulation or collection of
microorganisms in water that endanger human health have been
in focus during the last several years. Zeolite-61 will be an ideal
collector of pathogens such as Giardia, Cryptosporidium, and
other oocyst and protozoa and their spores. Most of these
organisms and their spores are in the size range of 0.5 to 10
micrometers (microns). In contrast, the water permeable pores
in Zeolite-61 are mostly smaller than 0.05 microns; therefore
the zeolite fragment or granule can surface collect a high
percentage of these microorganisms while the water passes
through the zeolite fragment. The U.S. drinking water standards
for microorganism pathogens and turbidity can be easily met
using a natural, low-cost material, such as Zeolite-61 rather
than sand which is chiefly quartz grains.
