Focus on Akdolit Hydro products

High-performance silica-free special carbon  

Akdolit® Hydro-Anthrasit P is a filter material for water treatment manufactured by breaking and screening a special thermally treated coal. The abrasion-resistant material grains are characterised by their jagged surface structure and a rounded granular form.  
Akdolit® Hydro-Anthrasit P is an inert filter material and releases almost no silicic acid, hardness or salts into the water. Therefore it is particularly suitable for boiler feed-water treatment.  
Akdolit® Hydro-Anthrasit P is mainly used as top material layer in two-layer filters based on the multi-layer filtration process and in single-layer filters for the filtration of condensate.
