Filtering and adsorbent media for water, gas, biogas and industrial applications.

Beyond activated carbon

Reactive S.r.l. supplies selected materials that complete filtration, purification and treatment systems for liquid and gas streams.

Zeolites: natural microporous minerals for ion exchange and absorption.
Anthracite and quartzite: durable filtering media for multi-layer beds and pre-filtration.
Pyrolusite and ferric hydroxide: specific products for contaminant removal and biogas treatment.

Applications

The choice of material is assessed according to the contaminant, the stream to be treated and the plant operating conditions.

Drinking water, industrial wastewater and process water treatment.
Pressure filters, sand filters and multi-layer filter-bed systems.
Biogas purification, odour reduction and cogeneration plant protection.

Product range

Zeolites

Natural volcanic minerals made of aluminosilicates, with a honeycomb structure rich in micropores.

Ion exchange to retain ammonia, heavy metals and other positively charged substances.
Absorption of liquids and gases due to high porosity.
Used in filtration, purification, agriculture and technical construction.

Anthracite

High-carbon fossil coal, strong and low-friability, used as a filtering medium.

Drinking water, industrial wastewater and municipal treatment.
Multi-layer filter beds with quartz sand and gravel.
Lower pressure loss and longer runs before backwashing.

Pyrolusite

A mineral mainly made of manganese dioxide (MnO₂), used as a filtering medium and oxidising catalyst.

Iron and manganese removal from drinking water.
Oxidation of arsenic and sulphides in the presence of oxygen or chlorine.
Used in granular filter beds, also mixed with quartz sand.

Quartzite

A metamorphic rock composed almost entirely of silicon dioxide (SiO₂), suited to water filtration.

Suspended-solids removal in sand and pressure filters.
Pre-filtration in reverse-osmosis plants.
High chemical and mechanical resistance, long service life and easy washing.

Ferric hydroxide

A product used in biogas plants to reduce hydrogen sulphide (H₂S), an odorous and corrosive gas.

Reacts with H₂S and binds sulphur as iron sulphide.
Protects cogeneration engines and reduces maintenance costs.
Can be used in the digester or in dedicated filters before biogas use.

Activated carbon

Highly porous carbonaceous materials that adsorb organic substances, impurities, odours and unwanted compounds in liquids and gases.

Filtration and purification of water, air and gas streams.
Decolourisation and purification in food and beverage, pharmaceutical and chemical sectors.
Can be reactivated in many industrial applications.
