VIDROMAR takes up more space than silica sand due to the difference in particle density and its Anti-Compaction Technology®. You will therefore need 20% less than the amount recommended by the manufacturer in the filter instructions.

Silica sand loses its filtration capacity in a short time due to the growth of a biofilm (bacterial colonies) between its grains, which creates preferential channels and clogging.

The absence of biofilm and the Anti-Compaction® technology make VIDROMAR one of the most efficient filter media on the market.

Yes, all standard filters can be used with VIDROMAR. If your filter does not have the globally harmonised nozzle opening size (0.35 +- 0.015 mm), we recommend replacing the nozzles with standard nozzles.

The combination of layers of different grain sizes within the filter is necessary when the filter media is not equipped with Anti-Compaction Technology®, in order to delay clogging and to be able to backwash correctly.

Thanks to its highly calibrated media grain curve, VIDROMAR does not require different layers in any type of filter. This also guarantees an indefinite service life.

VIDROMAR has been designed and produced specifically for use in water filters. To ensure maximum purity, only virgin glass is used. It is the only glass whose origin is controlled and which is guaranteed not to have come into contact with bacteria or any other contaminating material.

Unlike other glass filter media, it does not come from urban glass banks and is therefore the only one suitable for the filtration of water intended for human consumption.

Glass takes on its colour at the time of manufacture through the different chemicals, metals and oxides that are added to achieve each colour. Encapsulation at the molecular level does not change the properties of the glass and does not affect the filtering process. However, because the glass used for coloured filter media comes from glass banks and not directly from the manufacturer, it can contain all sorts of bacteria and contaminants that can end up in the water, making it unsafe for use in water filters for human consumption.

Thanks to its advantages and technical characteristics, VIDROMAR is currently used in more than 100,000 installations worldwide. It is mainly used in :

• Private pools
• Public swimming pools
• Advanced industrial facilities such as water treatment plants, water parks, nuclear facilities, desalination plants and aquaculture circuits, among others.

By definition, filtration is a mechanical process in which no other forces are involved. Unwanted particles are retained in a filter due to the interaction between the water flow and the filter medium. Due to its insulating nature, glass does not allow the free flow of electrons, so it cannot be “charged” or “activated”.

Other manufacturers claim that their glass is ‘activated’, but this has not been supported by any studies or demonstration.

1. Half fill the empty filter with water to protect the nozzles.
2. Fill the filter with 20% less VIDROMAR than recommended by the filter manufacturer.
3. Backflush for 5 minutes, then flush again for 2 minutes.
4. Switch the valve to filtration mode. Backwash the filter when the pressure exceeds 1.5 bar.

VIDROMAR is committed to sustainability and reducing its environmental footprint. This is why we work with FSC-certified packaging from the outset, thus avoiding the use of thousands of kilograms of plastic.

In addition, VIDROMAR is produced from recycled virgin glass and contributes to a significant reduction in energy and water consumption in swimming pools around the world.

And we continue to work every day to apply intelligent and sustainable solutions at every stage of production.
