Flange 30 has an internal seal on shaft 12 and is rotatable around the drive shaft 12. The disk is for example made of rubber, is oversized relative to the flare 28 and includes screw or bolt holes for attachment to the flange 30 on the flange 30 of the drive shaft 12. In assembly, the disk 31 is arranged over the drive shaft 12 and bolted secure onto the flange 30. The disk is oversized in diameter d + relative to diameter d of the flare 28, so that the disk 31 will cover the entire flare 28, even if the drive shaft 12 is not perfectly centrally aligned with a center axis of the flange 15. A ring 32 is also provided and has bolt or screw holes 33 aligned with the bolt or screw holes on flare 28. The ring 32 may have the same diameter as the flare 28, but could have a different diameter, but bolt or screw holes 33 pre-arranged in ring 32 (or later provided) must be in line with the bolt or screw holes on the flare 28. When the ring is arranged against the oversized disk, passages can be made in the outer periphery of the disk 31, bolts or screws may be inserted through holes 33, passages (nor shown) made in outer periphery or disk 31 and into bolt or screw hols 29 to fix the ring 32 onto the flange 15 and clamp disk 31 in between. Thereafter a surplus of material or disk 31 may be cut off, and the motor may be connected to drive shaft 12.
Figure 8 exhibits an embodiment of connecting a roll shaped holder 8 to either of a motor 12 and a neighbouring roll shaped holder 8 (for example when neighbouring cassettes 5, 6 are to be drive using a single drive or motor and rotational drive of holders 8 of cassettes 5, 6 need to be coupled).Figure 8 exhibits of an embodiment of connecting a roll shaped holder 8 to either of a motor 12 and a neighboring roll shaped holder 8 (for example when neighboring cassettes 5, 6 are to be using a single drive or motor and rotational drive of holders 8 or cassettes 5, 6 need to be coupled).
In this embodiment, each of the roll shaped holder 8 and the opposing roll shaped holder 8 or opposing motor 10 comprises a bus 34 having an accommodation in the form of a hole or recess 35. For coupling the roll shaped holder 8 on the left in figure 8 with any one of motor 10 and opposition roll shaped holder 8 to the right in figure 8, a block is inserted into the accommodations and distance is minimised. Thereafter the holder 8 to the left is driven by the holder 8 or motor 10 to the right in figure 8. The bus 34 provides room for suspending the roll shaped holder in the cassette 5, 6 and does no necessarily have to be embodied in the opposing holder 8 or the motor 10.In this embodiment, each of the roll shaped holder 8 and the opposing roll shaped holder 8 or opposing motor 10 comprises a bus 34 having an accommodation in the form of a hole or recess 35.

Thereafter the holder 8 is driven by the holder 8 or motor 10 to the right in figure 8. The bus 34 provides room for suspending the roll shaped holder in the cassette 5, 6 and does not necessarily have to be embodied in the opposing holder 8 or the motor 10.
Above, embodiments of the present disclosure are described in some detail, but such detail is not limiting on the scope of protection afforded to the present disclosure as defined in the appended claims. For example, pulleys may be used instead of the cogwheels in combination with rails in the form of chains, to achieve mobility of the cassette relative to the embodiment of figures 5 and 6. The cassette of figures 1-4 maybe in a dry well, a wet well, or simply in the pool extending along a side edge thereof. These few alternatives are just illustrative of a few alternative embodiments, which go to show that the embodiment description above comprises considerable detail of the embodiments, which can all be altered and changed, without overstepping the bounds or borders of limits to the scope of protection under the present disclosure, which includes in most jurisdictions also obvious alternatives, also for the dependent claims.Above, expired of the present disclosure are described in some detail, but such detail is not limiting on the scope of protection afforded to the present disclosure as defined in the appended claims.
