General
The Oleopator-PR NS 80 Class I and II
light liquid separators have a 3000-litre
sludge trap. The Oleopator-PR NS 100
Class I and Class II light liquid separators,
however, have no integrated sludge trap.
A sludge trap can be installed upstream
of the light liquid separator to trap sedi-
General function of Class I light
liquid separators
Light liquids in the Oleopator-PR Class I
light liquid separators are separated out
by a coalescence unit (2) which helps trap
the finest oil drops and coalesce them
together to form larger oil drops capable
of being separated out. This coalescence
unit (2) consists of two cylindrical coales-
cence elements centrically positioned
General function of Class II light
liquid separators
No coalescence unit is required in the
Oleopator-PR Class II light liquid separa-
tors. Light liquids are exclusively sepa-
rated out statically via the flow path and
the dwell time within the separator.

The latest ACO Civil Engineering cata-
logue for separators and pumping sta-
tions designed for ground installation and
the latest General Building Authority certi-
fication of the Oleopator-PR contain all of
the necessary dimensions and layouts of
around the float cage. The coalescence
materia consists of a PE-HD supporting
basket and usually a multilayered co-
alescence mat made out of a mixture of
knitted materials (stainless steel or poly-
propylene) wrapped around the supporting
basket and held in position by tensioners
and Velcro strips.
