SLUDGE CONDITIONING WITH COMPOSITIONS COMPRISING AN ANIONIC SURFACTANT AND A MINERAL CATION

摘要

The invention concerns the use for conditioning sludge derived from stations purifying waste water by biological process, compositions obtainable by mixing an anionic surfactant solution whereof the non-ionic part exhibits a HLB value not more than 10 with a mineral cation solution with a charge not less than 2.
