Nature Works® Glass Filter Media
Last generation filter media
Just by changing your current filter media for Nature Works® you will maximize every standard filter’s performance.
Nature Works® Glass Filter Media is a filter media made from virgin granulated glass, designed to replace the silica sand in any standard filter available on the market and intended for both domestic (swimming pool) and industrial water filtration.
It is the only water treatment filter media that provides maximum performance; reusability; energy, water and chemical savings; certified purity and total safety during installation. It is an ecological, recycled and recyclable product that reduces the environmental impact of water treatment.
Thanks to its advanced Anti-Compaction Technology, its smooth edges and its polyhedral morphology, it prevents the appearance of biofilm and chloramines. It does not require flocculants and reduces pressure loss to a minimum. The quality of Nature Works® Glass Filter Media is guaranteed by international product, production, water treatment and traceability certifications.
advantages and benefits
Nature Works® provides fundamental advantages in the characteristic fields of a filter medium:
Accredited Absence of Biofilm
The aseptic properties and the Anti-Compaction Technology of Nature Works avoid the formation of biofilm. This important characteristic is accredited by accreditation laboratories.
Biofilm is responsable for chloramines, clogging and channeling in the filter mass. With the use of Nature Works you will find a difference straight away.
Certified Absence of Free Silica
The crystal silica is a compound mineral that can be found in rocks and sand and may be found in filtration sand. A long term exposure to this compound could lead to various lung problems.
Free silica is considered a cancerous substance by IARC (International Agency for Cancer Research).
Nature Works® avoids this hazard as it has no Free Silica in its composition. Certified by Bureau Veritas Certification number BV ES026775-A-CPI.
Filtering micron rate
The efficiency of Nature Works is based on the elimination of the most common particles you can find in a swimming pool that make the water go misty. This simultaneously maximizes savings and efficiency.
The utility of a filter media is determined by a compromise between micron rate and clogging capacity.
Due to its advantages and technical characteristics, Nature Works® can be found today in more than 100,000 installations all over the world. Its main uses are found in:
Public swimming pool
Frequent Asked Questions
We help you solve some of the most common questions
How much Nature Works® glass will I need for my filter?
Nature Works® takes up more space than silica sand because of its particle density difference and its Anti-Compaction Technology, therefore you will need 20% less than the amount recommended by the manufacturer on the filter instructions.
Why does Nature Works® offer better results than silica sand?
Silica sand loses its filtration capacity in a short period of time due to the growth of biofilm (bacterial colonies) between its grains, which creates preferential channels and clogging.
The absence of biofilm plus Anti-Compaction Technology makes Nature Works one of the most efficient filter medias on the market.
Why does Nature Works® only need one layer?
The combination of layers with different sized grains inside the filter is needed when the filter media has not Anti-Compaction Technology, in order to delay clogging and be able to do a correct backwashing.
Thanks to its High-Calibrated filter media grain curve, Nature Works® does not need different layers in any kind of filter. This also ensures an indefinite shelf life.
Is Nature Works® compatible with all filters?
Yes, all standardized filters allow the use of Nature Works®. If your filter does not have the worldwide harmonized nozzle opening size [0,35 +- 0,015 mm], we recommend you change the nozzles for standard ones.
Why is Nature Works® transparent?
Nature Works® has been designed and produced specifically for use in water filters. To ensure maximum purity only virgin glass is used, it’s the only glass with controlled origin and guaranteed not to have been in touch with bacteria or any other contaminating materials.
Unlike other glass filter media, it does not come from urban glass banks and therefore is the only one suitable for water filtration for human consumption.
Is colored glass just as efficient as the transparent one?
Glass obtains its colour when its being manufactured due to different chemicals, metals and oxides being added to achieve each colour. As it is encapsulated at a molecular level, this does not change any of the glass ́s properties, nor does it affect the filtering process.
However, as the glass used for the coloured filter media comes from glass banks, not directly from the manufacturer, it may have all sorts of bacteria and contaminants that can end up in the water, which makes it risky to use in water filters for human consumption.
In which sectors may Nature Works® be used?
Thanks to its advantages and technical characteristics Nature Works® is used in over 100.000 installations all over the world.
Used mainly in:
- Private pool
- Public pool
- Advanced industrial installations such as purification plants, water parks, nuclear installations, desalination plants and aquaculture circuits among others.
Is Nature Works® “activated” ?
By definition, filtration is a mechanical process where no other forces intervene, unwanted particles are retained in a filter due to the interaction of the water flow and the filter media.
Due to its insulant nature, glass does not allow the free circulation of electrons, and therefore it is not possible to “charge” or “activate”. Some other manufacturers claim that their glass is “activated” yet this feature has not been backed up by any studies or demonstration.
Is Nature Works® able to “filter certified 1 micron”?
All our models are able to filter 1 μm. with crescent effectiveness.
The model with highest effectiveness is not recommended for swimming pool because due to its minimum clogging capacity, it obligates to make continue backwashing and it is thrown out to the sewage in the backwashing process.
The recommended use for this model is, generally, applications without suspended matter > 10 μm.
A Certificate has to be issued by a Certification Company, which does not issue filtration micron rate certificates. We count on the tests from the french IFTS laboratories for filtration.
