HS-100

Hydrosil’s HS-100 is a granular natural zeolite. The HS-100 has a high capacity for removing ammonia/ammonium from liquid phase.

Zeolite filtration has also shown better performance than other medias such as sand and sand/anthracite media for particle filtration. The HS-100 is found in aquariums, residential drinking water filtration, wastewater treatment, stormwater treatment, mining trailing ponds, and agriculture industry. The HS-100 product is NSF 61 Certified for drinking water applications.

The HS-100 can be loaded in drums or vessels for treating water in free standing mode for a P&T system, pre-treatment mode, or as a polishing treatment. To learn more about common treatment system designs or how to use the filter media visit the Filter Media Applications Page.

What is Zeolite?

There are roughly 40 types of natural occurring zeolites in the world.  Natural zeolites are formed from sedimentary rocks or volcanoes which are essentially hydrated aluminosilicate minerals. There are 150 plus types of synthetic zeolites which are artificially made for specific purposes. Synthetic zeolites are manufactured to have uniform structure. Zeolites are hard solids which have high melting points. The material is unreactive and made with naturally occurring minerals. Zeolites are used in a variety of ways including water softeners, pet litter, catalysts, concrete production, and remediation.

Understanding Ammonia/Ammonium

Ammonia in water exists as ammonia (NH3) and ammonium (NH4+). Depending on the pH and the chemistry of the water, the equilibrium and the presence of ammonia and ammonium will vary in your water. With a neutral pH and typical environments, most ammonia occurs as NH4+. As temperatures increase and the pH in the water changes the amount of NH4+ will decrease and the concentration of NH3 will increase. Typically when testing is completely on a contaminated water source, the total presence of free ammonia (both NH3 and NH4+) are accounted for.
