Nature Works and NW40 glass filter media and their application in industrial processes

High performance and reliability for industrial applications

In industrial environments, water quality is a critical factor that directly influences process efficiency, end product safety and operating costs. The presence of suspended solids, sediments, biofilm, or contaminants can lead to performance losses, equipment clogging, increased energy consumption, and more frequent maintenance. To meet these demands, our filter media offer advanced solutions specifically designed for industrial applications where effective, stable, and sustainable filtration is required.

Two technical solutions tailored to industry

Nature Works – Virgin glass (NSF 50 and NSF 61)

The Nature Works filter media is made from high-purity virgin glass. It is NSF/ANSI/CAN 50 and NSF/ANSI/CAN 61 certified, making it suitable for both general industrial applications and those where water is in direct contact with food, beverages or processes requiring drinking water quality.

Its calibrated grain structure, with no sharp edges and free of free silica, prevents filter bed compaction and biofilm formation, ensuring stable operation and long service life even under demanding conditions.

NW40 – Recycled green glass (NSF 50)

NW40 is a filter media made from controlled-source recycled green glass, designed for industrial applications where drinking water certification is not required. It is NSF/ANSI/CAN 50 certified and offers excellent technical performance, with high solids retention capacity and very low pressure drop.

Thanks to its manufacturing process and Anti-Compaction® Technology, NW40 keeps the microchannels of the filter bed open for longer, reducing backwash frequency and operating costs. It is a solution particularly suitable for continuous industrial processes and cooling systems.

Key technical advantages in industrial applications

  • High filtration efficiency: Both filter media enable the effective removal of suspended solids, fine sediments and organic particles, protecting downstream equipment such as heat exchangers, valves, pumps and spray systems.
  • Drastic reduction in pressure drop: The shape and particle size of the filter glass promote a more uniform water flow, significantly reducing pressure drop compared to traditional media such as silica sand. This translates into lower energy consumption and greater process stability.
  • Less biofilm formation: The smooth, chemically stable surface of the glass, together with its disinfection treatment, inhibits bacterial growth and biofilm formation, one of the main problems in industrial filtration systems.
  • Less frequent backwashing: By preventing the filter bed from compacting, the cycles between washes are lengthened, reducing water consumption, downtime and equipment wear.
  • Long service life and reusability: Filter glass does not degrade with use, does not round off or release particles, allowing for a long service life and a significant reduction in replacement costs.

 

Main industrial applications

Food and beverage industry

In the food and beverage industry, water quality is an essential requirement. Nature Works filter media, certified to NSF 50 and 61, guarantees high-quality filtered water for washing, production, formulation and cleaning processes, complying with the most demanding health regulations. Its use contributes to improving the safety of the final product and reducing the risk of cross-contamination.

Industrial cooling processes

In open or closed cooling circuits, the accumulation of solids and sediments can reduce thermal efficiency and increase energy consumption. Both Nature Works and NW40 improve the performance of these systems by keeping the microchannels of the filter media open, reducing pressure drop and optimising heat exchange. This translates into lower operating costs and greater system reliability.

Side-stream filtration in cooling towers

Side-stream filtration is a key application for maintaining water quality in cooling towers. The use of glass filter media reduces sediment accumulation, minimises sludge formation and improves overall system efficiency. As a result, equipment life is extended, purges are reduced and maintenance costs are lowered.

Economic and operational benefits

  • Reduced energy costs, thanks to lower pressure loss.
  • Water savings by reducing the frequency and duration of backwashing.
  • Less maintenance, with fewer unplanned shutdowns and greater equipment reliability.
  • Greater sustainability through the use of recycled glass (NW40) or highly durable materials with low environmental impact (Nature Works).
  • Optimised return on investment due to the combination of long service life and reduced operating costs.

 

Nature Works and NW40 glass filter media represent an advanced and reliable solution for filtration in industrial applications. Their high performance, low pressure drop, biofilm resistance and long service life make them a superior alternative to traditional filter media, helping industries optimise their processes, reduce costs and move towards more efficient and sustainable models.
