NEXTSAND is a High Performance Polishing Filtration Media. It replaces multimedia for a reduced footprint and higher quality filtrate. Alternative filtration media (such as Zeoplus, Turbidex, Aquazel) are from the family of common clinoptilolite zeolites, where as nextSand has some very unique properties such as the high Opal content (very hard, and gives its green tinge), and is higher in purity – that is, it has less ‘soft rocks / minerals’ within the rock mineral structure, such as lime and clays (calcite, lime and mica) which are soft and lead to ready bed attrition. Surface area measurements in 1999 for clinoptilolite filter media, based on analytical measurements (Gemini Model 2360, Micrometrics, Inc., Norcross, GA) indicated: a) that the clinoptilolite used for water filtration ranges from 14 to 29m2/g; and b); the presence of mineral contaminants (such as calcite, lime & clay) negatively impacts the surface area.
nextSand has a much higher surface area – Based on crystallography, the basic atomic structure of nextSand media consists of four (4) atoms of oxygen equally spaced. With this tetrahedral crystal structure (Si2O4) oxygen atoms are shared with other Si2O4 structure to form the unique even crystal framework. This gives nextSand a consistant surface area of 26 – 27m2/gram, whereas common clinoptilolite zeolites have a published surface area of 14m2/gram, up to 25. The surface area of nextSand is indicative of nextSand’s high purity. It is also the reason for the high filtration velocity nextSand is to be operated at. The rare high purity of the nextSand mineral sets it apart from all other known clinoptilolite deposits and the presence of Opal in nextSand’s mineral structure provides superior strength and stability. High surface area also equals higher filtration efficiency and effectiveness.
nextSand’s unique even crystal framework A revolution in filtration peformance and operating economy. nextSand™ is a remarkable advance in media filtration technology. Based on a rare natural mineral that is highly processed and refined, nextSand™ unique properties allow it to radically alter the performance 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. nextSand™ performs as a true depth filter–the water flows through the porous crystalline matrix as well as around the nextSand™ granules in the filter bed.
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 Service 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
RO Pretreatment–superior SDI reduction.
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
High Purity and Hardness. Choose nextSand™.
Only one USA mine produces high purity clinoptilolite, (any of a group of hydrated silicates of aluminum with alkali metals, occurring as secondary minerals used for their molecular sieve properties because they undergo dehydration with little or no change in crystal structure) and is the sole supplier of nextSand™ filter media. The nextSand™ is mined, crushed, sieved (e.g. 14 x 40 mesh) and kiln dried. Natural, high purity nextSand™ filter media has the high surface area and high porosity in addition to surface micro-crystals that makes it an ideal filter media. The ultra-high surface area and surface micro-structure of nextSand™ significantly increases particle removal from water compared to conventional filter media The rare high purity of the nextSand™ mineral sets it apart from all other known clinoptilolite deposits and the presence of Opal in nextSand™ mineral structure provides superior strength and stability. nextSand™ is inert and stable over the entire pH range >1 to <14. Only high purity nextSand™ media has the quality and purity needed to achieve reliable filtration performance and filter bed longevity.
