Anthracite

Our Anthracite is a premium quality product that complies with UNE-EN 12909 and AWWA B100 regarding drinking water treatment for human consumption, and it has the NSF worldwide certificate. Its use is optimal in single-layer or multimedia filters. Thanks to its angular shape and in combination with sand, garnet or gravel, high performance is achieved with lower pressure drop. As a result, better filtration runs and longer time between backwashes. Counting with references in desalination plants of more than 600,000 m3/d in the MENA area, Asia and South America, our product has consolidated its position in the market. In BB 1 m3 and 25 kg bags.

Zeolite VIDEO play

In compliance with the parameters of UNE-EN 16070, Zeolite supplied by KEIKEN has also the NSF worldwide certification. Its use is highly recommended in seawater and brackish water desalination plants and drinking water treatment plants. Of natural origin, and with a reduced carbon footprint, it can retain suspended particles from 1 micron upwards. As main advantages, our zeolite can operate at higher filtration speeds, achieving a significant reduction of SDI and Turbidity, also extending the time between washes. Contact us to study your case and evaluate the advantages of using this product. In BB 1 m3 and 25 kg bags.
