Oil separators (EN 858-1)

Separator systems for light liquids (e.g. oil and petrol) according to EN 858-1, also called oil separators, are waste water treatment plants in which light liquids are retained and separated. The functional principle is based on the difference in density between water and, for example, oil. The lighter phase (petrol, oil) floats up and can then be sucked off the water surface. The coalescence separator offers a further and effective method. Fine oil droplets are deposited on the surface of a special filter insert and finally join together to form an oil film. After a certain layer thickness is reached, the oil film breaks off and forms a larger oil drop which rises in the water and is separated.

On request, PIA GmbH will test your separator according to EN 858-1, whereby a practical test on your separator determines, among other things, the class and the nominal size.
