Developed as a powerful alternative to traditional quartz sand to enhance the quality of mechanical filtration in industrial water treatment processes, glass media is a state-of-the-art, next-generation filter material. Produced from recycled glass that has been specially treated, washed, and activated, this material filters suspended solids (SS) and turbidity from water with exceptional precision.
Traditional filter sands wear down, crumble, and create an environment conducive to bacterial growth over time. However, the structural smoothness and self-sterilizing capability of glass media—a powerful alternative to sand filters—ensure that your treatment system operates both more hygienically and significantly more efficiently.
The Filtration Difference of Glass Media and Its Two Primary Functions
Active glass media, which is used in place of quartz sand in existing multimedia filter tanks, offers two unique engineering advantages for the purification process:
High Filtration Efficiency
While quartz sand filters with an average particle size of 20–30 microns, glass media provides excellent filtration down to 5 microns thanks to its unique particle structure. This ensures that even the finest sediments in the water are captured, significantly improving the quality of the water flowing to the downstream reverse osmosis membranes and protecting the membranes.
Preventing Biofilm (Bacterial) Formation
Bacteria and microorganisms colonize by adhering to rough surfaces such as sand (forming a biofilm). The completely smooth surface of the glass media and its special electrical charge make it impossible for microorganisms to adhere to the bed. Thanks to this feature, it functions as an excellent bacteria-resistant filter and prevents the formation of unpleasant odors or microbial contamination in your water.
Benefits for Businesses
Using glass sand for water treatment at your facility directly reduces your operating costs:
- Less Backwash Water: Since contaminants cannot adhere to the glass, the backwash process takes 50% less time than with sand, resulting in significant water and energy savings.
- Longer Service Life: Glass media does not dissolve in water or break down from friction. Its service life is much longer than that of sand (on average 10–15 years).
- Lighter Construction: It is lighter than sand. You only need to purchase 15–20% less media by weight to fill the same filter tank.
Over 30 Years of Experience and Our Professional Team
Converting your existing sand filters to next-generation glass media or installing a high-efficiency system from scratch requires accurate hydraulic calculations. Since the density of glass media differs, it is essential to recalibrate backwash flow rates through automation. With over 30 years of engineering experience in the water treatment industry, we maximize filtration efficiency at your facility.
The draining of your filter tanks, internal cleaning, and the creation of glass media layers in granule sizes suitable for your flow rate are meticulously carried out by our professional team. With the highest quality media supply and proper automation integration, we ensure your process operates hygienically and without interruption at all times.
