A presentation about the clean-up efforts after the 2013 Danube flood in Bavaria. A particular focus is on the treatment of oil polluted flood waters via a Technomar SEPCON oil spill combating unit operated by the German disaster relief organisation THW.

4. The Problem:The Problem:
In the western part of Germany, many homes and
businesses are heated by oil powered furnaces. The
required fuel oil is stored in tanks on the premises, usually
in the basement.
In case of flooding, the oil from these tanks can leak
into the flood waters and pollute the environment

5. Oil Polluted Flood WatersOil Polluted Flood Waters

Often the oil polluted water is also
trapped in flooded basements,
where oil tanks and furnaces
were set up.

6. The Solution:The Solution:
SEPCON oil/water separation units
Why separate?
Water is the carrier medium
for the oil. All skimming
systems collect sizeable
quantities of water along with
the oil. The oil/water mixture
collected by the skimmers
contains only about 15 to 20%
oil, 50% at most. Hence,
storage tank capacities are
easily filled.
The solution is separating the oil from the water and storing
only the oil in the tanks, while the water is discharged.

7. SEPCON 80SEPCON 80
SEPCON units are compact oil/water separation systems with the
dimensions of a standard ISO 20‘ container. SEPCON units are designed for
mobility and may be employed wherever needed. Every SEPCON unit is
equipped with a diesel engine and therefore independent of outside power
supply. Throughput: 80 m³/h
Length: 6.06 m = 20 ft
Width: 2.44 m = 8 ft
Height: 2.59 m = 8.5 ft
Weight empty: 10 000 kg
Weight full: 25 000 kg
Max. oil content: < 50%
Max. viscosity: 70 000 cSt
Max. density: 0.99 g/m³
Flashpoint: > 60°C
SEPCON units separate oil and water in a direct
throughflow process, utilizing only the physical
principles of gravity and coalescence. Chemical
additives and long settling periods are not
necessary.

8. SEPCON 40SEPCON 40
The smaller SEPCON 40 unit was built for the German federal disaster
relief agency THW.
Throughput: 40 m³/h
Length: 6.06 m = 20 ft
Width: 2.44 m = 8 ft
Height: 2.59 m = 8.5 ft
Weight empty: 9 000 kg
Weight full: 20 500 kg
Max. oil content: < 50%
Max. viscosity: 10 000 cSt
Max. density: 0.98 g/m³
Flashpoint: > 55°C

9. The German government has 10 SEPCON units stationed all over
Germany, so they may be quickly deployed whenever needed.

10. Cleaning Flood Waters on the DanubeCleaning Flood Waters on the Danube
II
Two of the THW‘s SEPCON
units are currently employed
cleaning flood waters in
Southern Germany with
another two SEPCON units
on stand-by.
Altogether 53 THW volunteers
and civilian personnel are
working 12 hours a day to
clean oil polluted flood waters
and protect the environment.

11. Cleaning Flood Waters on the Danube IICleaning Flood Waters on the Danube II
18 tank trucks with a total
capacity of 195 m³ are
continuously delivering oil
polluted water pumped from
basements in the Passau and
Deggendorf region to the
SEPCON units.
The oil polluted water is held in
five buffer basins of 250000
liters capacity altogether to
await treatment.

12. Cleaning Flood Waters on the Danube IIICleaning Flood Waters on the Danube III
Another problem is that the flood
waters are not just polluted by oil
but by all sorts of dirt, debris and
floating particles. Therefore, the
water is led through a strainer
before it enters the buffer basins.
This is the debris caught in the
strainer after emptying only one
of the 18 trucks.

Skimmers skim the oil polluted
water from the surface of the
buffer basins and feed it into the

15. How it works: CoalescenceHow it works: Coalescence
The separation process utilizes the physical principle of coalescence on
oleophile surfaces.
Coalescence means that small oil
droplets adhere to oleophile surfaces
and form bigger oil drops.

coalescence
process seen
under the
microscope
Technomar separation
systems contain
coalescence elements like
the ones in the photo above.

16. After the Separation IAfter the Separation I
After the separation, the separated oil is taken by tank trucks
to the OMV refinery in Vohburg, Bavaria.
To date, 250 m³ of pure oil have
been separated and could be
reused. Otherwise this oil would
have polluted the environment.

17. After the Separation IIAfter the Separation II
After the separation, the clean
water is discharged into the public
sewer system.
After separation,
the residual oil
content in the
clean water is
less than 15 ppm.
To date, 2400 m³
of oil polluted
flood water have
been cleaned.
