A skimmer is a device in artificially created lakes, garden ponds or swimming pools and other liquid containers that sucks the dirt from the water surface.

Dust, leaves, oil or other pollution lead to the pond / lake water being enriched with too many nutrients from the outside and thus becoming algae and cloudy. A skimmer in a pond or lake prevents this process and does not even allow the surface contamination to cloud the water. A correspondingly larger number of suction points is installed in larger bodies of water. Skimmers can also be used to purify cooling water, for example.

Basic structure (example)

Exemplary structure of a skimmer: A pipe with a large diameter installed vertically in the water, which becomes larger / wider towards the surface of the water; Connected via a pipe connection to a suction pump, in front of which a coarse dirt filter (sieve) is attached.

Oil skimmer

Disc skimmer

Skimmers can also be designed with an endless hose to which the oil sticks. The hose floats on the surface and removes floating oils and fats from the surface of the liquid by means of a carrier. This collects the oil or fat from the surface and is cleaned by scrapers in the device. The removed oil or fat is then collected in a separate container. There are mainly three designs.

  1. Hose skimmer : Here, the entrainment is implemented via a floating endless hose . The advantage: thanks to the variable hose length, even large pools can be cleaned well. Disadvantage: Not suitable for small and very small pools.
  2. Belt skimmer : The oil / fat is discharged via an endless belt. Very suitable for medium and small pools. Disadvantage: A high proportion of dirt or solids leads to premature wear.
  3. Disc skimmer: Similar in size to the belt skimmer, with the discharge through a disc. Advantage: less sensitive to dirt than belt skimmers. Disadvantage: only suitable for small pools.
  4. Flotation skimmer : The dirt particles that have risen from flotation are removed from the surface of the water with the help of a flotation skimmer (also called a flotation skimmer). This type of skimmer is also suitable for large pools, for example 100 m² .
