A revolution in filtration performance and operating economy.

next-Sand™ is a remarkable advance in media filtration technology. Based on a rare natural mineral that is highly processed and refined, next-Sand™'s 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.

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 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.

  • Applications


  • RO Pretreatment–superior SDI reduction
  • Cooling Towers–unequalled Turbidity removal
  • Power Generation Plants
  • 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
  • Irrigation

    Over the past 50 years, improvements in granular media filtration have been achieved by: a) using smaller mesh size sand to remove finer particles, b) by combining sand with garnet or garnet and anthracite (i.e. “multimedia” beds) and c) by improving the fluidics design of beds and vessels. More recently the traditional sand or multimedia filtration beds have started to make way for zeolite based filtration units. Natural zeolites are a low cost resource recognised for their unique absorption, catalytic, ion exchange, and molecular sieve properties; Clinoptilolite is a natural zeolite but it varies greatly in both structure and purity. next Sand is a rare high-purity Clinoptilolite that offers the very best characteristics for use as water filtration media.


    next Sand™ offers a single bed media made from high purity Clinoptilolite, which delivers superior performance over conventional filter sands or multimedia, and at a lower cost. The material is mined in Western USA and then highly processed and graded; the resulting product is hard and stable with a high surface area and micro-porous character in addition to surface micro-crystals making it an ideal filter media. next Sand™ has high filtration performance at <5 micron compared to 12 to 15 micron for multi media. It also has a higher flow capacity, typically three to four times that of multimedia. This higher flow rate means a greater performance can be achieved from existing vessels when upgraded with next Sand, or for new applications smaller filter vessels would be required to achieve the same results. Filtration through the entire media bed depth provides more than twice the capacity of multimedia filtration. It has a higher dirt holding capacity so requires less frequent backwashing, leading to reduced downtime. Lighter weight and lower volume requirement means lower capital and shipping costs than multimedia and the product also lasts longer. The media isn’t consumed in the filtration process; a simple periodic backwash will keep the media clean and operating efficiently for five years or more.

    next Sand™ is suitable for use in vertical or horizontal vessels and pressure or gravity feed systems. It can be therefore used in a broad range of applications in the water and wastewater industry including:

  • Reverse osmosis pre treatment with superior silt density index (SDI) reduction
  • Cooling towers with unequalled turbidity removal
  • Municipal water treatment, pressure and gravity filters with higher flow, low pressure drop and superior filtration performance
  • Desalination plants
  • Swimming pool and Spa filtration with high Ammonia removal
  • Wastewater polishing with exceptional total suspended solids (TSS) removal
  • Precipitated metals removal
  • Carwash reclaim and recycling
  • Irrigation

  • The unique properties of next Sand™ high purity Clinoptilolite filter media allow it to radically alter the performance and cost of media filtration. Compared to conventional sand or multimedia filtration beds, the main advantages are as follows:

  • Superior filtration performance
  • Higher flow capacity
  • Higher dirt holding capacity
  • Reduced backwash time and frequency
  • Lower capital cost
  • Long lasting media

  • next Sand™ is NSF/ANSI 61 and BS6920 certified and complies to EU draft standard pr EN16070 for drinking water.
