NW40 is a family of filter media based on recycled glass that has been developed exclusively for liquid filtration. Among other features, it has been purified through the most advanced ecological process and is packaged in HQ recyclable bags.

Each type of industrial filtration has different typical suspended matter with different size ranges, therefore each “Stage type” of NM40 is focused on retaining different size ranges, simultaneously optimising savings, efficiency and maximizing utility.

The target size ranges are enforced using the High Calibration Technology, which allows to control the size and proportion of the micro channels formed in the filter mass to create different “Stage type” settings.

PERFORMANCE

Filtration Quality or Filtration Performance depends on the Retention Capacity – total

suspended matter retained . The High- Calibration Technology grants high Retention Capacity in any circumstances.

Maximum Utility through the optimisation of Micron-rate Vs Clogging Capacity balance to obtain high filtration quality keeping convenient periods between backwashing processes

EFFICIENCY

This High-Calibration Technology has been developed to keep open the micro channels that are formed in the filtering mass. Thanks to this effect pressure drop is negligible and clogging capacity is extreme.

Consequently, pump consumption is very low and backwashing process periods are enlarged, getting therefore sensible energy and water savings.

DURABILITY

The same open-micro channels effect allows a constant flow through the whole filtering mass, creating Anti-Biofouling effect. Bear in mind that Biofouling comes in compaction effect and eventually, in the end of the filter media lifespan.

On the other hand, the particle is enclosed to surface micro polishing treatment to reach maximum hardness.
