With the convenience of sand and extremely low maintenance, outlasts sand and glass by many years and can be regenerated. Reduces backwashing.
Zelbrite for water filtration was being used by ancient civilisations 2,000 years ago. Modern sand filters filled with Zelbrite far exceed the performance of D.E. (Diatomaceous earth) filter. They are also much far more economical and require little maintenance (no addition of powder, or replacement of the filter material, etc.).
Note:
Zelbrite™ is an advanced filtration media that out-performs the traditional pool filtration mediums of sand and Diatomaceous Earth (DE). Zelbrite upgrades standard sand filters into high performance water purifiers that are the lowest maintenance and easiest to use.
>It has been precisely engineered to provide unparalleled performance in filters in response to market pressure for an efficient, ecologically sustainable and long lifespan media.
The stability and hardness of Zelbrite makes it the ideal media for nearly every water processing application, from domestic and commercial pools, potable water treatment systems to domestic and industrial wastewater treatment.
Each backwash consumes 20 – 25% less water. Higher dirt holding means fewer backwashes for any given application, up to half as many of which significantly reduce water consumption and loss of salt in saltwater chlorination systems.
Zelbrite lowers the output required from salt water chlorinators extending the cell plate life. No modifications are required to standard sand filters to accept Zelbrite - it can therefore can be used as an upgrade when the sand is replaced.
What is it? How does it work?
Zelbrite is manufactured to exacting standards from natural zeolitic material sourced from our mine at Werris Creek in New South Wales. This natural material was formed over 300 million years ago as a result of volcanic activity in the vicinity of a large freshwater lake. Over the passage of geological time, this material was overlain by hundreds of meters of other material giving rise to a zeolitic material of exceptional hardness and durability. In fact, a material exceptionally suited to "filtration" applications.
The active ingredient of the zeolite is "clinoptilolite", a mineral with very special properties. These include an exceptionally high surface area, an infinitely extending three-dimensional cage-like structure with large internal pore spaces, and the ability to chemically capture pollutants by a mechanism called "cation-exchange".

Zelbrite FAQ's
Zelbrite is the filter media of the future and has much more to offer.
Zelbrite 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 15kg bag of Zelbrite is equivalent in volume to a 20kg bag of sand.
Most filters have a name plate which will give you the size of the tank, e.g. 24in and also specify the amount of sand required, for example 140kg, which is 7x20kg bags of sand, or 7x15kg bags of Zelbrite.
Tests carried out by an Australian water quality centre prove that Zelbrite filters out dirt particles down to 2 microns. This compares with sand at 15 microns and diatomaceous earth (DE) at around 5 microns. Zelbrite also removes ammonium ions which inhibits formation of potentially harmful chloramine compounds.
Zelbrite is an Australian product. It is manufactured from naturally occurring zeolitic material which was formed as a result of ancient volcanic activity over 300 million years ago.
Are all zeolites the same?
No, Zelbrite is made from uniquely very hard zeolitic material. Most zeolites found throughout the world are soft and friable and are therefore unsuitable for use as pool filter media.
Why do I have to backwash and rinse three times when I first install Zelbrite?
As with new sand, you must backwash and rinse several times to clean out any dust. With Zelbrite these backwash and rinse cycles ensures that any adhering clay is removed, and importantly, the different particle sizes are separated - the finer material rising to the top of the filter tank and the coarser grains settling to the bottom covering the laterals.
Do I have to modify my filter?
No, all domestic and commercial sand filters are suitable for use with Zelbrite.
What does Zelbrite Regeneration mean?
Zelbrite is able to adsorb ammonium ions from water however over time it will become saturated and unable to take up more ammonium ions. The process of regeneration removes the adsorbed ammonium ions, effectively 'refreshing' the Zelbrite. Even if Zelbrite is not regenerated, say once every one or two years, this will not affect its superior filtration performance.
f I want to regenerate my Zelbrite, how do I do it?
The procedure is very simple. It comprises adding sufficient pool salt to the filter to produce a 10% concentration, leave stand overnight before backwashing two or three times.
Can I use Zelbrite with a Saltwater Chlorinator or Ioniser?
Yes. Some of our distributors are also leading filter and saltwater chlorinator manufacturers and they recommend their chlorinators and ionisers be used with Zelbrite filters.
f I have a saltwater pool do I still need occasionally to regenerate my Zelbrite?
Yes, saltwater chlorinators typically produce water with a salt level of around 4-6000ppm which is not concentrated enough to regenerate the Zelbrite.
How often do I have to replace Zelbrite?
Filter manufacturers have always recommended that sand should be changed every 4 to 6 years. Zelbrite will give you 8 to 10 years or even longer.
Will I have to backwash as often if I change from sand to Zelbrite?
No, Zelbrite's superior filtration capability results in fewer backwashes being required. You should expect an extra 4 weeks between backwashes.
Do I use more water to backwash and rinse with Zelbrite?
No, tests actually show that you can save up to 50% of water when using Zelbrite.
Yes, Zelbrite is used in many commercial pools. Among the latest to choose Zelbrite are:
Does Zelbrite have any effect pH?
No, Zelbrite is pH neutral.
No, Zelbrite is manufactured entirely from a naturally occurring zeolitic mineral resource. The manufacturing process does not involve treatment with, or addition, of any form of chemicals or other materials.
EVALUATION
Comparison of Filter Medias with same or close Effective Size. Glass as a coarse or medium AWWA media is ineffectual and is being sold as a fine media not conforming to AWWA standards.
Zelbrite is the only filter media that has been approved by Smart WaterMark as a water saving product. (See www.smartwatermark.org for more information).
*All filter performance based on Rapid Sand Filter Rate, 2.5 to 4.0 l/m2/sec
Zelbrite is manufactured from Werris Creek Zeolite which is one of the hardest Zeolites in the world, with a hardness of around 7 on the Mohs scale.
Not all Zeolites are the same and cannot all claim to have the Smart Approved WaterMark. Zelbrite has been awarded this mark after extensive testing.
Zelbrite is sourced from ancient 304 to 360 million year old Werris Creek Zeolite. Many other Zeolites like those from Indonesia or New Zealand are much younger and generally softer.
Glass media has recycled glass mainly bottles as its raw material. This means there is no control over the glass used and this can range widely in its quality, hardness, and source of supply.
A requirement of glass for bottles is that they have a hardness of less than 5 mohs to be ductile enough for transport, point of sale handling, and safety in the home.
Zelbrite is one of a suite of filter media’s produced by Zeolite Australia Pty. Limited conforming to AWWA standards.
Some glass media’s claim to have attained overseas accreditation but do not have Australian WaterMark certification and do not conform to the AWWA standard.
Sands and Zeolite have only 1 production stage, glass has an extremely high production energy and is an inefficient process (SilicaGlassRecyclingCrushing and Grading)
Werris Creek Zeolite is a proven product with close to two decades of continuous use in Australian filters.
Glass as a filter media was introduced by Australian Glass Manufacturers (AGM) in the early 1980’s and had proven costly to both contractors and suppliers and was subsequently withdrawn from the Australian market.
At end life of the filter media Zelbrite is simply a Zeolite which is approved for agricultural use where ground glass can only be disposed of to landfill.
Any media with a Coefficient of Uniformity greater than 2.0 is unsuitable as an efficient filter media.
Coefficient of Uniformity dictates the dirt holding capacity of a media; the lower the ratio the more even thfilter media grain size, hence the inter-particle space is increased.
In recent times the Australian Skin Council has embarked on an education plan to help ward off skin cancers using all forms of suntan lotions and block out. Although this is very important to stop sunburn it has caused problems with pool filtration but can simply be overcome by de-greasing the filter media.
All filter medias are effected. Cartridge filters, sand media, glass media - even Zelbrite filter media.
This can be done simply by using a detergent (there are many different brands on the market) but for best ad safest results, we recommend FilterKleer .
From experience this needs to be done every 12 months to clean all the oil and grease out of the media and is best done during the warmer months when the water temp is over 24 degrees. This will help release the build up which will cause the backwashing to become more frequent. With more frequent backwashing you will use more water, more chemicals which puts up the cost of running a pool.
For an average commercial filter you would need to use 1 to 2 litres of FilterKleer per filter depending on bathing loads. This can be put into the strainer pot before starting backwashing - when the pump is started up the detergent will enter the filter from the bottom washing up through all the filter media removing the build up of grease and oil which will then be pumped out through the backwash line and down the drain.
