PuroziteTM is a zeolite based filter media developed especially for water treatment by Starke Filter Media. Zeolite is a group of naturally occurring minerals composed of aluminum, silicon, and oxygen. They have a unique crystalline structure with a high surface area and a network of interconnected pores.

Why choose PuroziteTM?


Filtration to 2 microns

Lab tests performed by Water Quality Centre mimicked both in and above ground pool conditions. Results showed a filtration of dirt particles down to 2 microns filtering out giardia, cryptosporidium, and ammonia.

Increased efficiency

Our product has been proven to improve the filtration flow rate by a minimum of 30%; generating faster more efficient filtration. Additionally, because of the hardness of the product it doesn’t degrade at the same rate as other media such as sand.

Graded to retrofit existing systems

The cost of swapping to our media is not prohibitive. The product is graded to retro fit existing sand filters so you don’t have to spend excessive amounts of money to reap the reward.

Superior Filtration

With all the unique properties of purozite, the pool water not only gets a superior “physical” treatment but an additional “chemical” treatment, resulting in cleaner pool water.
No other filtration medium on the market (such as sand and diatomaceous earth (DE) can produce this “double whammy” treatment of pool water!

Purozite in Waste Water Treatment

Industrial waste waters contain toxic heavy metal ions such as lead (Pb), cadmium (Cd), chromium (Cr), nickel (Ni), copper (Cu), and zinc (Zn). Municipal waste waters contain high amounts of ammonium. These toxic elements must be removed from aqueous solutions before disposal; otherwise they can cause serious environmental problems. They can contaminate water sources.

The ion-exchange process is the most attractive, simple and cost effective method to remove the toxic elements in waste water. Purozite mineral contains exchangeable cations, such as Na+, K+, Ca2+, and Mg2+, in its structural framework. Ammonium and heavy metal ions in wastewater is replaced by these cations during ion exchange.

How much Purozite do I need in my filter ?

Our product has a lower bulk density than sand, hence you require 75% by weight of the amount of sand required, and this will vary depending on the size of the filter. A 25 kg bag of Purozite is equivalent in volume to a 40 kg bag of sand.

Purozite is a highly porous mineral. Dust inside the pores can blur the water at first usage. In order to prevent blurring of the water, please back/wash the mineral until the dust in its pores is completely removed.

Packaging is available in 25 kg bags, and is consistently delivered on time.
