DGS advanced water purification unit

DGS®-DRYDEN GLASS SAND FOR ECO-FRIENDLY WATER FILTRATION

DGS® is an advanced filtration media made from 100% recycled glass in Dryden Aqua’s state-of-the-art facilities. Unlike AFM®, DGS® is produced from mixed glass and is not activated. 
Despite this, DGS® delivers ultra-fine mechanical filtration while significantly minimizing bacterial clogging compared to traditional sand filters. Produced in full compliance with ISO standards, DGS® undergoes a unique washing process using 100% rainwater—ensuring the purest and safest non-activated glass media available today. 

BENEFITS OF DGS®

  • Cleaner, Clearer Water: Removes up to 30% more particles than standard sand filters.
  • Reduced Chemical Use: Achieve high filtration efficiency with less chlorine consumption.
  • Healthier Environment: Minimizes trichloramine formation for better air quality in swimming areas.
  • Lower Water Waste: Requires shorter and slower backwashing (240 seconds to clear 99% of retained particles at 45 m/hr).
  • Long-Lasting Performance: Maintains consistent efficiency throughout its life and lasts twice as long as sand.
