Glass Filter Media For Swimming Pool Filtration

For Swimming Pool Filtration
100% recycled material, reduces environmental impact through improved performance and lasts up to 10-15 years.

Running a swimming pool is expensive, and can be environmentally damaging. Today, utmost care must be taken to reduce water & energy consumption thus reducing environmental impact.

Weekly backwashing is required in sand filters to reduce built-up pressure as a result of debris settling in the sand bed. This uses a substantial amount of water. This water is then replaced and re-heated increasing energy consumption. All at a cost.

The density of glass improves the water flow. And as a result, Glass Filter Media needs less backwashing. This results in up to 50% less water usage. Which, in turn, reduces the energy and water costs. Less stress on the environment, cheaper & more efficient.

  • Glass Filter Media effectively filters microplastics, organic matter and heavy metals as small as 5 microns from the water. These contaminants are easily removed from the filter bed via less frequent & slower backwashes.
  • Glass Filter Media has a surface negative charge density which works well with coagulants and flocculants (such as Clear Maxx) to remove dissolved components.
  • Glass Filter Media prevents the growth of bacteria in the filter bed, completely eliminating bio coagulation. The channelling that occurs in sand filters is also eliminated.
  • Product water will have at least 50% lower chlorine oxidation demand than an equivalent sand filter, so much lower concentration of disinfection by products.
  • Silica Sand is a natural resource, hence over time as water passes through the media either via normal filtering or backwashing, its particle size decreases and in some cases the media hardens. It therefore creates pressure fluctuations, affecting the efficiency of your swimming pool water filtration system. Glass Filter Media doesn’t harden or cause pressure drops in your filter system. The media is much more durable and consistent during the filter's lifecycle.
  • Will last as long as your filter does and, in that time, will continue to provide crystal clear water, reducing the need for chlorine and thereby vastly reducing harmful chloramines and other by-products of disinfection.

Comparison of Sand and Glass Media

Criteria Sand Media Glass Media Advantage
Cleaning Ability Sand will filter to about 30 microns. Glass will filter down to roughly 5-10 microns.
Even finer particles than cartridge filters.		 Glass
Longevity Sand media needs to be changed out every
3-5 years depending on the water and
debris load that is going through the filter.		 Glass media lasts about 2-3 times
as long as sand filter media.		 Glass
Backwashing Sand will require longer backwashing to clean the dirt
out of the system as there is more volume of media to go through.		 Glass media will backwash quicker as the material is lighter and less dense, so it floats better, resulting in faster cleaning. Faster cleaning also means less water usage. Glass
Price Sand filter media, generally speaking, requires four bags to fill the filter and is more cost effective. Glass media since it is finer will only require roughly 50% fill capacity at a slightly higher cost but with more value. Sand
