Drydan Glass Sand (DGS) – Grade 1

Drydan Aqua Glass Sand Filter Media is also referred to as DGS

DGS is a filtration media made from 100% recycled glass in Dryden Aqua’s ultra-sophisticated glass factories. In contrast to AFM®, DGS is made from mixed glass, and it is not subjected to any activation process. Nevertheless, DGS allows ultra-fine purely mechanical filtration while suffering a lot less from bacterial clogging than sand. Like AFM®, DGS is produced in strict compliance with ISO specifications and undergoes a unique washing process using 100% rainwater to become the best, safest and purest non-activated glass media on the market.

The glass is washed using 100% rainwater, decontaminated and carefully broken to the appropriate particle shape and size. Above all, we make sure no dangerous glass splinters can get into the filter material and that the organic load is below 100g per ton. Other glass media have a contamination between 500g and 10‘000g per ton.

Key Benefits of Drydan Aqua DGS

• Clearer water and reduced chemical consumption: DGS removes up to 30% more particles than sand.
• Less chlorine smells: DGS reduces the formation of trichloramines in the filter for a healthier atmosphere in swimming pools.
• Less backwash water: DGS needs shorter and slower backwashes than sand (240 seconds to evacuate 99% of retained particles at 45 m/hr).
• Stable performance and longer lifespan: DGS has less efficiency loss over a complete filtration cycle and 2 times greater longevity of sand.
