Zelbrite (zeolite) and Swimming Pool Thailand filters

There is no better product than zeolite on the market today for use in traditional  ]swimming pool sand filters.

Proven by  independen sudies and researched by laboratories and universities.

Our  Zelbrite Zeolite is manufactured by 

ZEOLITE AUSTRALIA PTY LTD

and is directly  imported from  them.

It  is marketed under many different brand names. This is because the Zeolite company  allows companies to market the product under their own brands, and zeolite offers their customers the possibility  of packaging  the the product  under their customers' brands. This is a perfectly  legitimate and normal trading process used for many services and products world-wide.  remember the Austin  Min, the Morris Mini, the Riley  Elf, and the Wolsley Hornet? These were all  the same car in  the 1970s and 1980-s; the only  difference was the badge and the radiator grille.

Whatever barnd zeolite is marketed under,  such  as Davey Zelbrite filter media   Zeobrite, ZeoSand, Zeolite Sand, ZeoPure, ZeoCem Eco  it  is all  the same product. However, other bnrands sold as  as Zeolite Pool Filter Media is actually ground volcanic tuff that may  comprise only  a small  percentage of actual  genuine zeolite.

Normal swimming pools sand filters sold by Swimming Pools Thailand only  require 70 -  75% Zelbrite by  weight  of sand. That  means, if your  filter should be filled with  100 Kg of sand, it  will  only  needc 70  -  75 Kg of Zelbrite. That  is why  at swimming  Pool Thailand we market pur  original  Zelbrite zeolite in  15 Kg bags.

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™ Sand Filter Diatomaceous Earth Media "Zelbrite" used continuously for many years Sand used continuously for 4 - 5 years Diatomaceous Earth replaced after every backwash Filtration Efficiency Excellent Good Excellent Filters To 2-3 microns 15 microns 5 microns Multiple Mechanisms Yes No No Removes Ammonia Yes No No Reduces Chloramines Yes No No Convenience Excellent Simple backwash Excellent Simple backwash Not so convenient Backwash to also remove unused DE Operating Cost Low as virtually permanent medium * Low as virtually permanent medium Medium, requires regular replacement of DE Less volume, more filtration: Zelbrite only requires 70 - 75% of the weight of sand Less backwashing (water saving approx 30%) Less energy consumption Buffer effect helps maintain pH level Less pool chemicals - Zelbrite performs chemical ion exchange to absorb ammonia making the pool water safer and more appealing. Zelbrite can be simply recharged by your local pool shop to keep it performing at its best. Using New filters Use the spreader if one was supplied with your new filter. Partly fill the filter with water Avoid breathing the dust. Do not allow any media to enter the centre pipe - cover it with a plastic cup. Ensure an even spread all round. Thoroughly clean the O-ring grooves before assembling the MPV or attaching the side mount unit. Do NOT lubricate the O-ring with Vaseline™ or any petrolueum jelly, use only silicone grease. Existing filters If you are refilling an existing filter, be sure to replace the O-rings for the top-mount MPV or the port flanges on side-mount filters. Order them from from us before you start. Do NOT lubricate the O-ring with Vaseline™ or any petroleum jelly. Remove the MPV (top-mount) or the plumbing (side-mount) Allow the filter unit to drain overnight - wet sand is is very heavy Completely remove the old media (turn the filter upside down). Do not allow any media to enter the centre pipe - cover it with a plastic cup. Ensure an even spread all round. Remove any excess sand and carefully clean the O-ring grooves.

Zelbrite FAQ's

Why should I use Zelbrite instead of sand in my filter?

Zelbrite is the filter media of the future and has much more to offer.

1. The performance of D.E. with the ease of sand.
2. Better filtration (2 microns) means a saving in chemicals usage and better looking water.
3. Removal of ammonia - better swimming comfort - no smell - no more irritation to skin and eyes.
4. Because of its greater surface are you will not have to backwash as often - on average twice as long between backwashing therefore saving water - up to 50%
5. Leading Australian swimming pool filter manufactures recognise these benefits and have chosen to promote this ultimate filter media.
6. No only has Zelbrite been chosen as the best form of filter media in domestic pools it is being used in many aquatic centres - swim schools and council pools through Australia and overseas.
7. Zelbrite comes from a naturally formed volcanic rock which is mined at Werris Creek in Northern N.S.W. Australia.

How much Zelbrite do I need in my filter?

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 volumer 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.

How well does Zelbrite filter

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.

What is Zelbrite made from?

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 therfore 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, oyu must backwash two or three times to clean out any dust. With Zelbrite the three 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.

If 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.

If 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.

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.

Is Zelbrite used in commercial pools?

Yes, Zelbrite is used in many commercial pools. Among the latest to choose Zelbrite are:

• The Canberra International Sports and Aquatic Centre
• Adelaide Aquatic Centre
• Glenn Innes Swim Centre in Northern N.S.W
• Tweed Regional Aquatic Centre Murwillumbah (opened in Nov '08)
• Richmond Pool in N.S.W.
• Esplanade Lagoon Cairns

Does Zelbrite have any effect pH?

No, Zelbrite is pH neutral.

Are there any additives or impurities in Zelbrite?

No, Zelbrite is manufactured entirely from a naturally occurring zeolitic mineral resource. Our manufacturing process does not involve treatment with, or addition, of any form of chemicals or other materials.
