The best filtration for water treatment plants

Efficiency and safety in water treatment processes are fundamental elements to guarantee the supply of quality drinking water, comply with regulations and optimise plant operation. Nature Works is positioned as a state-of-the-art filter media, made from recycled glass, which offers technical, operational and environmental advantages over traditional media such as silica sand.

NSF/ANSI 61 certification: support for drinking water applications

One of the most relevant aspects of Nature Works is that it is the only glass filter media with NSF/ANSI/CAN 61 certification. This accreditation ensures that the product is safe for use in drinking water applications, meeting stringent international public health standards.

NSF/ANSI 61 certification represents a significant advantage for water treatment plant operators, engineers and contractors who require reliable and validated filter media for processes in direct contact with water intended for human consumption.

Superior technical performance

The Nature Works manufacturing process is designed to produce a material with optimal physical characteristics for filtration. These properties allow for more effective and stable filtration over time. Among its main technical advantages are:

Higher retention efficiency: With a filtration capacity of 99.64%, tested by IFTS laboratories. Its structure improves the capture of fine particles, increasing the clarity of the treated water and reducing turbidity.
More efficient use of the filter volume: Unlike silica sand, Nature Works allows a more uniform distribution of solids within the filter bed, favouring more efficient filtration and with less risk of compaction and formation of preferential channels.
Lower pressure drop: The shape and granulometry of the media allow a better hydraulic flow, reducing the required pressure and energy consumption.

Operational optimisation and cost reduction

The implementation of Nature Works in treatment systems contributes directly to the optimisation of the operation:

Decrease in the frequency of backwashing, thanks to its greater solids retention capacity.
Reduction in water and energy use associated with more spaced and efficient backwash cycles.
Longer filter media life, which reduces maintenance and replacement costs.

These benefits translate into improved overall filtration system performance, with positive impacts on operational continuity and associated system lifecycle costs.

Sustainability and environmental responsibility

Nature Works also stands out for its sustainable profile. It is made from 100% recycled glass, which represents an alternative . In addition to this, there are other key environmental benefits:

Solid waste reduction, by reusing glass that would otherwise end up in landfills.
Lower water and carbon footprint, derived both from its durability and the lower use of resources in operation.
Sustainable manufacturing process: thanks to the energy generated at the plant itself, thanks to the large number of solar panels installed and the supply from nearby renewable plants; Nature Works is manufactured with 100% clean energy.

These characteristics make it a suitable choice for projects that prioritise compliance with ESG (environmental, social and governance) standards and corporate sustainability policies.

Wide range of applications

Nature Works is a versatile filter media, successfully used in a variety of applications including:

Municipal and rural drinking water treatment plants.
Industrial pretreatment systems and recirculation processes.
Tertiary treatment in wastewater plants.
High-demand commercial and residential systems.

Its excellent compatibility with pressure, gravity, multimedia and deep bed filters makes it a flexible and efficient solution for new projects or retrofitting existing installations designed for traditional filter media.

Nature Works represents an evolution in filter media technology, combining high technical performance, certified drinking water safety and a strong commitment to environmental sustainability. Its NSF/ANSI 61 certification makes it a reliable alternative for applications where end-user safety is a priority, while its durability and operational efficiency position it as a strategic investment for treatment plant operators and designers.
