Thw sepcon danube_flood


Published on

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. 4. The Problem:The Problem:In the western part of Germany, many homes andbusinesses are heated by oil powered furnaces. Therequired fuel oil is stored in tanks on the premises, usuallyin the basement.In case of flooding, the oil from these tanks can leakinto the flood waters and pollute the environmentOil powered furnace Oil tanks for home use
  5. 5. Oil Polluted Flood WatersOil Polluted Flood WatersFlooded residential neighbour-hood in Deggendorf, Bavaria.Note the oil tank floating on thewater.Often the oil polluted water is alsotrapped in flooded basements,where oil tanks and furnaceswere set up.
  6. 6. The Solution:The Solution:SEPCON oil/water separation unitsWhy separate?Water is the carrier mediumfor the oil. All skimmingsystems collect sizeablequantities of water along withthe oil. The oil/water mixturecollected by the skimmerscontains only about 15 to 20%oil, 50% at most. Hence,storage tank capacities areeasily filled.The solution is separating the oil from the water and storingonly the oil in the tanks, while the water is Technomar
  7. 7. SEPCON 80SEPCON 80SEPCON units are compact oil/water separation systems with thedimensions of a standard ISO 20‘ container. SEPCON units are designed formobility and may be employed wherever needed. Every SEPCON unit isequipped with a diesel engine and therefore independent of outside powersupply. Throughput: 80 m³/hLength: 6.06 m = 20 ftWidth: 2.44 m = 8 ftHeight: 2.59 m = 8.5 ftWeight empty: 10 000 kgWeight full: 25 000 kgMax. oil content: < 50%Max. viscosity: 70 000 cStMax. density: 0.99 g/m³Flashpoint: > 60°CSEPCON units separate oil and water in a directthroughflow process, utilizing only the physicalprinciples of gravity and coalescence. Chemicaladditives and long settling periods are notnecessary.
  8. 8. SEPCON 40SEPCON 40The smaller SEPCON 40 unit was built for the German federal disasterrelief agency THW.Throughput: 40 m³/hLength: 6.06 m = 20 ftWidth: 2.44 m = 8 ftHeight: 2.59 m = 8.5 ftWeight empty: 9 000 kgWeight full: 20 500 kgMax. oil content: < 50%Max. viscosity: 10 000 cStMax. density: 0.98 g/m³Flashpoint: > 55°C
  9. 9. The German government has 10 SEPCON units stationed all overGermany, so they may be quickly deployed whenever needed.Operated by the THW:Lübeck (SEPCON 80)Nordenham (SEPCON 80)Cloppenburg (SEPCON 40Berlin (SEPCON 40)Essen (SEPCON 40Borna (SEPCON 40)Frankfurt/Main (SEPCON 40)Obernburg (SEPCON 40)Kelheim (SEPCON 40)Operated by the Fire Brigade:Hamburg (SEPCON 80)
  10. 10. Cleaning Flood Waters on the DanubeCleaning Flood Waters on the DanubeIITwo of the THW‘s SEPCONunits are currently employedcleaning flood waters inSouthern Germany withanother two SEPCON unitson stand-by.Altogether 53 THW volunteersand civilian personnel areworking 12 hours a day toclean oil polluted flood watersand protect the environment.
  11. 11. Cleaning Flood Waters on the Danube IICleaning Flood Waters on the Danube II18 tank trucks with a totalcapacity of 195 m³ arecontinuously delivering oilpolluted water pumped frombasements in the Passau andDeggendorf region to theSEPCON units.The oil polluted water is held infive buffer basins of 250000liters capacity altogether toawait treatment.
  12. 12. Cleaning Flood Waters on the Danube IIICleaning Flood Waters on the Danube IIIAnother problem is that the floodwaters are not just polluted by oilbut by all sorts of dirt, debris andfloating particles. Therefore, thewater is led through a strainerbefore it enters the buffer basins.This is the debris caught in thestrainer after emptying only oneof the 18 trucks.

  14. 14. The Separation ProcessThe Separation ProcessOilresidualwater content:less than 1%Oil/water mixtureoil content:up to 50%viscosity:up to 70 000 cStdensity:up to 0.99 g/cm³flashpoint:> 60°CWater:residualoil content:less than 15 ppmSeparation UnitThroughput: 80/40 m³/h
  15. 15. How it works: CoalescenceHow it works: CoalescenceThe separation process utilizes the physical principle of coalescence onoleophile surfaces.Coalescence means that small oildroplets adhere to oleophile surfacesand form bigger oil drops.Thecoalescenceprocess seenunder themicroscopeTechnomar separationsystems containcoalescence elements likethe ones in the photo above.
  16. 16. After the Separation IAfter the Separation IAfter the separation, the separated oil is taken by tank trucksto the OMV refinery in Vohburg, Bavaria.To date, 250 m³ of pure oil havebeen separated and could bereused. Otherwise this oil wouldhave polluted the environment.
  17. 17. After the Separation IIAfter the Separation IIAfter the separation, the cleanwater is discharged into the publicsewer system.After separation,the residual oilcontent in theclean water isless than 15 ppm.To date, 2400 m³of oil pollutedflood water havebeen cleaned.
