EVERZIT® N
Anthracite filter media in accordance with EN 12909
EVERZIT® N is a natural anthracite filter material produced in Germany. Especially favorable geological processes formed anthracite with a particularly special structure. Our unique refining process of cleaning, crushing and sieving ensures our capability to convert anthracite to premium-quality filter media for single-layer and multi-layer filtration. It has a proven track record spanning more than 45 years in successful water treatment worldwide.

Features and benefits
EVERZIT® N has by nature ideal characteristics for a filter media:
- High abrasion resistance
- Withstands high-speed backwashing without media wash-out
- Optimum separation of filter layers during backwashing
- Good retention, even of particulates with high specific gravity
- No adhesion of precipitated ferrous- and manganese compounds
- No silicic acid leach-out into water
Applications
Dual media filtration avoids conventional "surface-only" filtration as found in sand filter beds. Particulate retention occurs throughout the media (in-depth filtration) which offers considerable advantages, i.e. lower investment costs and reduced operating costs:
- longer run time between backwashes
- reduced pressure drop
- higher filtration speeds feasible
- reduced backwash-related downtime and costs
- higher treatment capacity
- improved filtrate quality
