Our filter media: the efficient technical solution for agricultural irrigation systems

In modern agricultural irrigation systems, water quality and distribution system efficiency are critical factors. Suspended solid particles, sediments, organic matter, metal oxides and other solids can clog emitters, drippers, micro-sprinklers, lateral pipes or pivot systems, damaging irrigation uniformity, increasing maintenance costs and reducing crop yields. In response to this scenario, our NW40 and Nature Works Hi Tech filter media offer an advanced, sustainable and cost-effective alternative for agricultural irrigation.

Two products adapted to agricultural requirements

Nature Works (virgin glass certified to NSF 50 and NSF 61)

This filter media is made from virgin glass of the highest purity, subjected to micro-polishing and edge removal processes and free of free silica. It is certified according to international standards NSF/ANSI/CAN 50 (recreational use/water treatment) and NSF/ANSI/CAN 61 (drinking water), which guarantees that it is suitable for the most demanding installations and applications in terms of water quality, hygiene and filtration performance. Thanks to its calibrated particle size curve and Anti-Compaction® Technology, this product offers superior filtration performance, lower pressure drop and longer service life.

NW40 (NSF 50 certified recycled glass)

NW40 is a range of filter glass made from recycled green glass of controlled origin, processed using a dual disinfection system (ozone + UV radiation) to guarantee cleanliness and quality. It is certified according to the NSF/ANSI/CAN 50 standard, which guarantees its excellent performance and manufacture in accordance with strict quality criteria. It also offers a more economical price range.
Both products share the Nature Works philosophy: high performance, lower water and energy consumption, durability, and certified material traceability.

Key technical advantages for agricultural irrigation

High solids retention efficiency: Thanks to optimised particle size distribution, the polyhedral structure of the grains and the absence of biofilm, the filter media capture fine particles and keep the microchannels open. This is essential for irrigation systems where emitters must be kept clean and free of clogging. We also offer several specific curves to adapt to the needs of any installation.
Reduced hydraulic head loss: Due to its shape, calibration and anti-compaction technology, head loss through the filter bed is minimised, reducing the load on the pump and energy consumption on farms.
Less backwashing required: By keeping the microchannels open and reducing compaction, the intervals between backwashing are lengthened, which means water savings (a key resource in agriculture) and fewer interruptions to the irrigation system.
Purity and safety of the material: In the case of Nature Works, NSF 61 certification guarantees suitability for drinking water, which means that it can also be used in agricultural irrigation of high-value or sensitive crops. In the case of NW40, the double disinfection treatment makes it suitable for demanding agricultural applications.

Recommended applications in irrigation systems

Pre-filtration of variable catchment water: In sources such as wells, rivers, canals or reused water, where the solids load can vary, the installation of a filter with glass filter media helps to protect the system of pipes, emitters and valves.
Fine filtration before drip/micro-sprinkler emitters: In localised irrigation installations, where emitters have very fine holes and any particles can clog them, Nature Works or NW40 filter media ensure sufficient water quality to prolong the life of the system.
Recirculation or reuse systems in agriculture: When treated water, drainage or effluents are reused, the durability, cleanliness and efficiency of these filter media are a plus for keeping the system efficient and safe.
Pivot or large-scale irrigation installations: In high-flow irrigation systems, the energy savings achieved with lower pressure loss are more significant, making these filter media a good investment in large agricultural areas.

In short, if the installation requires maximum purity and certifications for drinking water or highly demanding crops, our solutions are the best option.

Operational and economic benefits for farmers

Greater irrigation uniformity and crop health: By reducing clogging in emitters, tapes, pipes and valves, water distribution is improved, promoting uniform growth, preventing water stress and contributing to better yields.
Reduced maintenance costs: Less backwashing, less need for filter cleaning or emitter replacement reduces both downtime and operating costs.
Water and energy savings: By extending cleaning intervals and reducing pressure loss, water and energy consumption in the system is reduced, which is particularly relevant in agricultural areas with water restrictions or high pumping costs.
Sustainability and regulatory compliance: Using recycled glass filter media reinforces the image of the farm as sustainable and can facilitate access to subsidies or quality certifications.
Fast return on investment: Although the initial investment may be higher compared to conventional media (such as silica sand), the operational savings (water, energy, maintenance) and the longer service life of the media mean that the return on investment is relatively short. And in the long run, it is a much more economical option. Especially considering the volatility of the price of resources such as water and energy.

Our filter media is a cutting-edge filtration solution for agricultural irrigation: it combines rigorous certifications (NSF 50 and, in the case of Nature Works, also NSF 61), high filtration efficiency, water and energy savings, extended durability and environmental sustainability. The use of recycled glass (NW40) or contaminant-free virgin glass (Nature Works) allows the solution to be adapted to the requirements of the agricultural system, optimising costs and guaranteeing performance.
For farms seeking not only to comply with technical and environmental standards, but also to maximise the operational efficiency and service life of their irrigation systems, both ranges represent a smart investment.
