Media Filter

GLS media filter is a direct replacement for sand filter. It has more than double performance of any other media filter, activated surface to adsorb fine particles including specific priority substances, heavy metals, and resists biological fouling.

Key Point

  • Media Filter is a direct replacement for sand in any type of sand filter without the need for further investment
  • Has more than double the fine particle retention performance of any other media
  • Has an engineered, activated surface to adsorb fine paerticles including specific priority substances, heavy metals and metalloids including arsenic.
  • Resists biological fouling and prevents resultant channelling.
  • Substantially reduces product water oxidation demand.
  • Reduces backwash water demand by an average of 50%
  • Provides quick return on investment, usually less than 2 years on water consumption alone.
  • Has a life cycle more than 4 times longer than sand.
  • Is certified ISO 9001: – 2015, ISO 14001 & 18001 standards & is certified HACCP NSF50 & for drinking water use under European DWI Reg 31 & NSF61.

Performance

  • will not support bacterial growth
  • at up to 20m/h will consistently filter, without flocculation:
    • >95% of 4µ particles (Grade 1)
    • >95% of 1µ particles (Grade 0)
  • will selectively filter positively charged ionic particles such as heavy metals
  • will not suffer from channelling or preferential pathways
  • will consistently evacuate more than 95% of retained particles using 50% or less water than required for sand. (backwash duration 5 mins max at 45m/h).
  • has a service lifespan of 10 – 15 years or more.

Some key examples

  • Pre-treatment prior to membranes
    Maintenance of cartridge filters and fouling of membranes for RO and ultrafiltration is a major cost.
  • Removal of arsenic, ferric and manganese
    Media Filter will remove many metal contaminants from the water, and is particularly effective for arsenic and ferric.
  • Cooling tower side-stream filtration
    Water treatment is essential for cooling tower recycled water.
  • Tertiary treatment of effluent
    Media Filter replaces sand in tertiary treatment filters without the need for any modifications.
