Definitions
- micro-orga ⁇ nisms In biological processing or treatment of waste water the organic content- therein is broken down by micro-orga ⁇ nisms sometimes growing on a substrate surface. Usually this micro-biological process is aerobic; that is, oxygen is used to break down the organic material. Consequently a number of designs have been invented in the past and one of the most useful is a rotating body with an enlarged surface (rotating biological contactor) , which is brought in and out of contact with air and waste water due to its rotation. In this way the micro-organisms are brought in contact with oxygen of the air as well as the waste water in the basin.
- the object of the invention is to provide a method with which these new materials efficiently can be used without loss of optimal conditions.
- OMPI IPO conditions that the rotor may have to be submerged to more than half its size, contrary to previous praxis according to which the rotor always has to bring the substrate in contact with the air as well as with the water.
- the rotor may well be submerged entirely without negative effects on the micro-biological growth conditions. In this, way it is in fact possible to use rotor materials with a specific surface of up to 300 m 2 per m3 which should be compared with the previously
- This device contains a basin, a bio ⁇ logical rotating contactor submerged to more than 50 % and with a specific surface of 110-300 m 2 per m3 volume of rotor. If materials with a very high specific surface, for example 120-250 m 2 per m3 rotor is used it may be of great advantage to arrange material towards the center of the rotor so that the specific area is less there in order to allow the water to flow more freely and provide for aerobic conditions there. Further a central part of the rotor may be left without contact material in order to allow an axial flow out of the rotor in these parts.
- OMPI arranging a big wheel which may be cogged or toothed and with which a driving smaller wheel which may be cogged or toothed can be in contact.
- the torque load on the primary gear box from the engine can be reduced exten- sively giving on the whole a more inexpensive arrangement.
- the drive can cope with a great torque resistance as the rotor from time to time may have unsymmetric growth and thus be unbalanced.
- it is also unnecessary to have the driving torque transmitted by the shaft on the rotor which may thus only have the effect of supporting the rotor.
- the rotor In order to further di ⁇ minish the stress on the rotor hsaft the rotor can be pro ⁇ vided with closed air spaces giving a lifting effect on the rotor in the water in order to balance the total weight of rotor and biological growth.
- the rotating biological contactor ma- terial has a specific surface of 150 m 2 per m3 this means
