Granular ferric hydroxide filter media in accordance with EN 15029
EVERZIT® As is a filter media based on iron (III) hydroxide oxide. Due to its high chemical activity, EVERZIT® As is ideally suited for adsorption of arsenic and other heavy metals.
A special manufacturing process is used to produce iron hydroxide in granular form. The granulometry of the product can be controlled in the process, permitting manufacturing of various product grades for a wide variety of application fields.
EVERZIT® As complies fully with the following standards and regulations:
*Note: While EVERZIT® As exceeds the permissible manganese content given in Table A.1 of EN 15029, this value is explicitly provided for informative purposes only and is in no way binding.
Water extraction testing clearly shows that manganese leach-out from EVERZIT® As occurs in trace amounts only, i.e. far below the limits specified in Germany's strict Drinking Water Ordinance.
EVERZIT® As is used in single-layer filters for
A two-stage process configuration is normally used, i.e. the raw water first passes through a dual media filter for particulate and/or iron and manganese removal and then through the EVERZIT® As filter.
