Glass Media Filter Plants – delivering ultra-fine, low-maintenance filtration that outperforms conventional sand filters for crystal-clear, resource-efficient water.
What It Does
Sarvoʼs Glass Media Filter Plants replace traditional silica sand with specially graded recycled- glass media, engineered into skid-mounted pressure vessels sized to each clientʼs flow, footprint, and water-quality targets. Water enters the vessel and percolates through the angular glass granules; their negative surface charge attracts and traps turbidity, algae, oils, and metals down to 3 5 µm, four to five times finer than typical sand media. Because glass is lighter and non-porous, it resists bio-fouling and channeling, sustaining high filtration rates (up to 20 m³ h⁻¹ m⁻²) with minimal head-loss. Backwash cycles are shorter and less frequent—glass needs 25 40% less rinse water and up to 30% less energy than sand systems. Media life exceeds ten years, two to three times the service life of sand, cutting replacement labour and disposal volumes. PLC-controlled valves automate filtration, backwash, and rinse modes, while optional inline turbidity sensors trigger demand-based cleaning to optimize uptime. Modular designs range from 5 m³/h polishing units to 500 m³/h high-throughput trains, integrating seamlessly with RO, UF, or disinfection stages for potable, process, or recycling applications.
Key Benefits
-
Finer Filtration Quality
captures particles as small as 3 5 µm versus 10 30 µm for sand, delivering visibly clearer water.
-
Lower Operating Expenses
25 40% less backwash water and associated pumping energy per cycle.
-
Sustainability
media manufactured from 100% recycled glass lowers embodied carbon and diverts waste from landfills.
-
Consistent Performance
non-clumping glass avoids channeling, maintaining steady head-loss and flow.
-
Longer Media Life
10 15 year service life, up to three times that of sand, reducing media- change downtime and costs.
-
Chemical Savings
reduced bio-film and bacteria growth can cut disinfectant demand by up to 50%.
-
Compact & Retrofit-Ready
higher loading rates allow smaller vessels or increased capacity in existing footprints.
-
Automated, Custom Control
PLC/IoT options enable demand-based backwash for 98% uptime.
