Dear CCl'ers
We have to remove a polyalkylenglycol in water. 
Formula : HO-CH2-CH2-[O-CH2-CH2-CH2]x-[O-CH2-CH2]yOH
Concentration in water : low
Molecular weight : 12000 g/mol
Solubility : halogenated solvents, alcool, water
We made tests with activated black carbon, ultrafiltration, floculation
but the costs are too high.
We could imagine to invest in a system but the treatments costs must be
low. 
Have everybody got a good idea ? We hope so ! 
Thank a lot for interesting in this subject.
