The problem is well known to everyone: when passing near sewage manholes unpleasant odours can often be smelled. These smells are not only unpleasant but they can even jeopardize people's health in case they contain the highly poisoning hydrogen sulphide.

Such smells and gases may arise in the canalisations when there is a stagnation of waste substances and no fresh water is added. Rotting processes inside canalisations can also contribute to odour building as well as to the production of hydrogen sulphide in case of anaerobic conditions. Our canalisation filters are able to solve this problem. A particularly efficacious canalisation filter is the Activated Carbon Filter belflor® AFIP 370 produced by Störk. The installation of this filter of about 5 kilos and a length of 420 millimetres is really easy and does not require the use of any kind of tool. The filling material, able of degrading bad smells, is constituted by special activated carbons with a very high specific surface, thus giving the activated carbon filter a great efficacy as well as a protection function. Also the substitution of the activated carbon filter is very easy.

Actually such a substitution takes place very seldom, as the carbon duration is usually about three years. This sewage manhole filter has just a low air flow loss. The activated carbon filter is endowed with a sealing for an excellent and precise tightness on the border and it is made of high dense polyethylene. This plastic material, also used to insulate landfill sites, is inert and resistant against chemical attack. For this reason the activated carbon filter is also resistant to ultra violet light for long time and does not tend to corrosion even in presence of corrosive substances. This material is guaranteed for ten years. Inside the canalisation filter we have integrated a very practical dust and sand sieve. With a special device we can make our activated carbon filter also suitable for Viatop,- Hydrotech-and Begu-covers. The activated carbon filter is also suitable for any sewer manhole according to DIN 4043.
