SandSilt-Sediment-TurbidityTM A radically high performance silt, sediment and turbidity media.Multi-MediaFiltration Performance3-5 Micron(nominal filtration)8-15 Micron(nominal filtration)Introductionnextsand is based on a rare natural mineral that is highly processed and graded. It’s unique properties allow it to radically alter the perfor-mance and cost of media filtration. The hardness, stability and micro-porous character of nextsand makes it a perfect filtration media for virtually every application in the water and wastewater treatment industry.Features• High filtration performance-3-5 micron removal.• High capacity filtration throughout the entire nextsand bed depth provides more than twice the capacity of multimedia filtration.• High flow– 3-4 times that of multimedia with superior filtration.• Long lasting media (>5 years) not consumed in the process.• Simple periodic backwash keeps the media clean and operating efficiently.Applications• RO Pretreatment–superior SDI reduction• Cooling Towers–unequalled Turbidity removal• Municipal Water Treatment, pressure and gravity filters–higher flow, lower pressure drop and superior filtration performance• Wastewater Polishing–exceptional TSS removal• Precipitated metals removal• Carwash reclaim and recycling• IrrigationPhysical Properties• Composition High Purity Alumino-Silicate• Size 0.4-1.4 mm (approx. 14x40 mesh)• Color Dark Gray• Surface Area 25m2/gram• Surface Absorption Hydrophillic• Thermal Stability Stable to 500° C• Coefficient of Uniformity 1.7• Bed Void Volume 55%• Surface Charge Net Negative• Bulk Density 55 lbs per ft3 (0.88 kg/L)• Packaging 1 ft3 bags, 1m3 supersacks.Performance Characteristics• Filtration (nominal) 3-5 micron• Surface Loading 16-20 gpm/ft2 (Typical) 12 gpm/ft2 (Optimized for silt, SDI and ultrafine particulates)Turbidity Reduction200150100500Multi-MediaFeed WaterTurbidity (NTU)Service Flow Rate (gpm/ft2)MultiMedia12-203-10Media & System CostMultiMediaSandSilt-Sediment-TurbidityTMSandSilt-Sediment-TurbidityTMSandSilt-Sediment-TurbidityTMSandSilt-Sediment-TurbidityTMnextsand MultiMediaSurface loading 15 gpm/ft2 5 gpm/ft2Surface area req’d 1.0 ft2 3.0 ft2Tank Dimensions 14” x 65” 24” x 71”Media volume req’d 3.2 ft3 10.8 ft3Media weight 216 lbs 1057 lbsBW flow req’d 17 gpm 51 gpmDaily BW volume 179 gal 510 galFiltration <5 micron <10 micronComparative cost 1X 3 XExample 1 .
