Activated-carbon filter cartridges by RENNER

RENNER activated-carbon filter cartridges

Features

Activated carbon filter cartridges are equipped with steam-activated coal pellets and designed especially for heavily loaded liquids. Due to the discharge form no blockage of the activated carbon surface is possible by coarse dirt and the service life is extremely long.

RENNER offers an extensive range of different activated carbon filter cartridges, as well as granular activated carbon in AC canisters.
These are used when the pure mechanical filter effect for the solutes is no longer adequate, since their size is only molecular.

Other properties

Activated carbons are differentiated (e.g. hard coal or plant residues such as coconut, etc.) and their delivery forms (pellets, block, granules, and powders) according to their sources of raw materials. In which type and form activated carbon should be used most effectively, depends on the customer's individual requirements.

Hard coal adsorbs many solutes from fluids excellently that cannot be otherwise mechanically filtered.
By the adsorption of activated carbon solutes such as oil, grease, pesticides, dyes and other organic compounds from liquids are absorbed and removed.

Excess chlorine or, for example, disinfecting ozone react with activated carbon and are rendered harmless.
Also odorants bind completely with activated carbon and can no longer escape. When bitter substances are once adsorbed by activated carbon, they cannot contaminate foodstuffs; activated carbon is therefore indispensable for the food industry.

Activated carbon is used very effectively, for example, in electroplating to remove interfering organic compounds from various baths.

The initial differential pressures are low due to the discharge and this determines the long service life.
