A method of cleaning a contaminated surface, such as cleaning the elongate interior lumen of an endoscope contaminated with flesh, bone, blood, mucous, faeces or biofilm, said method comprising the steps of: providing a suspension of solid particles in a liquid to said contaminated surface, and flowing said suspension along said surface thereby to remove contaminant from the surface. The suspension is preferably a paste, where the solid material may be e.g. crystals of a salt, silicon oxide or organic material. The paste preferably has a solid fraction between 5 and 55%. A rheology modifier may be present.

A skimming apparatus with a pivot arm and a drive follower on the pivot arm that guides a belting to facilitate precise placement of the belting for efficient skimming.

Separate cleaning assembly for magnet assemblies formed by at least one magnet rod, wiper assembly and magnet handle device, the cleaning assembly including a base and vertically extending main body, wherein the cleaning assembly includes retaining means for retaining the magnet assembly to the main body and receiving means for receiving and accommodating the wiper assembly, wherein the receiving means for the wiper assembly is arranged to moving means arranged for moving the wiper assembly in longitudinal direction of the magnet rods.

A washing and doping mechanism includes a bushing that is configured to engage a tubular that is in a substantially vertical orientation. The bushing is configured to rotate, thereby causing the tubular to rotate about a central longitudinal axis of the tubular. The washing and doping mechanism also includes a sprayer configured to spray a fluid onto the tubular in the substantially vertical orientation.

A cleaning device that passively self-adjusts to improve biofoul removal across curved, non-uniform, or irregular underwater surfaces. The cleaning device includes a motor, one or more shafts coupled to the motor and coupled to one another via at least one universal joint, and a cleaning mechanism for removing biofoul from the target surface. The cleaning device includes an alignment mechanism that restricts the cleaning mechanism's movement to improve biofoul removal. The alignment mechanism can include bearings, spring components, dampening material, adhesion components, floatation objects, or a combination thereof.

A cooling apparatus (1) for cooling a fluid with surface water, comprising at least one tube (8) for containing and transporting the fluid in its interior, the exterior of the tube (8) being in operation at least partially submerged in the surface water so as to cool the tube (8) to thereby also cool the fluid. The cooling apparatus (1) further comprises at least one light source (9) for producing light that hinders fouling on the submerged exterior, wherein the light source (9) is dimensioned and positioned with respect to the tube (8) so as to cast anti-fouling light over the tube's exterior. By this structure anti-fouling of the cooling apparatus (1) can be assured in an alternative and effective manner.

Many conveying units for media capable of flow are used for products that are harmful to the environment and at least attack the conveying units themselves over time or deposit in them and clog them. Cleaning of the conveying units is therefore recommended, but such cleaning represents an effort that is preferably not made, because of the effort involved. Against this background, an apparatus for cleaning of conveying units, which apparatus can run both in simple manner and practically without supervision, uses a cleaning circuit in which the conveying unit to be cleaned is short-circuited with a cleaning agent tank and thereby constant circulation of cleaning agent through the conveying unit to be cleaned is pumped and the unit is thereby cleaned.
