D 116 Bio-cleaning ( Date: 2004-07-08 )
Steel parts e.g. for construction are cleaned from oils, dust, corrosion protec., rust, welding residue and metal fines by a biological cleaning process in a multiple immersion plant (integrated pickling, fluxing and galvanising); thereafter galvanising

Recycling:

agent is recycled/reused within company
Agent and dirt are transfered to bath 2 as tramp liquid, where micro orgisms break down the matter to CO2 and H2O
agent is diposed of (annual amount) No statement
Dirt and cleaner from bath 1 are taken over continuously as tramp liquid to bath 2, where the micro organisms decompose it to CO2 and H2O. Only a very minor amount of sludge remains (dead micro organisms and fines, ca. 100 kg/a). To determine the disposal path, analyses will be carried out (most likely the dried stuff will be incinerated together with used engine oil, but a disposal together with sludge from waste water treatment plants seems also to be possible
