KESSEL light liquid separator EasyOil
- for underground installation
- for mineral-based light liquids
- with a density up to 0.95g/cm3g/cm3
- with automatic closure device
This separator is not intended for treating stable emulsions, so-
lutions of light liquids in water, grease and oil of vegetable or
animal origin.
Oil
and fuel separators are light liquid separators and are
used to protect bodies of water and sewer systems from
contamination with mineral oil products. They operate
based on the principle that low-solubility mineral oil pro-
ducts float in wastewater due to their lower specific density
and accumulate on the surface.
The wastewater flows into the oil/fuel separator via floor drains
without odour trap; the inlet pipes should be kept as short as
possible. A special inlet system in the KESSEL oil/fuel sepa-
ratorEasyOil causes so-called plug flow. This means that the
flow is uniformly distributed in the separator and is thus fully
hydraulically effective. The sediment deposits (all particles with
specific density higher than water) sink to the bottom, the light
substances move to the surface of the water. The outlet system
with automatic closure device prevents the discharge of sepa-
rated substances.
Oil/fuel separators
The separators are suitable for the following applications:
1. For treating surface water run-off contaminated with light li-
quids from hard surfaces (e.g. petrol stations, oil storage and oil
transfer areas, car parks and roads in water protection zones)
2. As retention or containment equipment for light liquids from
facilities and areas in or on which light liquids are handled, for
example:
- private fuel dispensers
- private cleaning and washing areas
- private workshops and repair areas
The permit to discharge into the sewers or bodies of water must
be agreed with the respective water authority.
Automatic closure device
The separators are equipped with automatic closure de-
vices.
This device prevents light liquid from discharging into the
sewage system if the maximum oil storage quantity in the
separator has been reached. In the KESSEL light liquid sepa-
rator
EasyOil
, this safeguard consists of a floater guide pipe,
which is normally filled with water. The floater is designed
so that it floats in water and sinks in the light liquid (up to a
density of 0.95 g/cm3). If the maximum oil storage quantity
is reached, the floater sinks and closes off the separator’s
outlet.
The automatic closure device of a separator is an “emergen-
cy brake”. If it is triggered in the event of an accident or spil-
lage, the separator must be shut down and serviced. Light
liquid separators must therefore be serviced and emptied,
and their contents disposed of, regularly.
Static calculation
The stability of the tank is only ensured for its self weight,
transport and for the described installation in accordance
with the intended use (e.g. load class, road construction).
Additional loads from single or strip footings or other ex-
ternal impacts must be avoided. If such actions are to be
expected, it may be necessary to take special measures.
