Filtration Media Zeolite-61
Particulate Reduction Media
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.
Bottle water and drinking water plants
Economical pre-filter for RO systems
Well water and industrial wastewater filtration
Cooling tower, chillers, heat exchanger water filtration
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.
