A bio-chemical treatment system was developed to reutilize the spent water-soluble coolant as a diluent of renewal coolant. The bio-chemical treatment using oil-decomposing microorganisms and a biological activated carbon filtration method showed a high recovery rate of water resource from an emulsion-type coolant. The water-soluble coolant can form the uniform micelle colloid in the recovered water and showed no quality change during the nine months standing at ambient temperature. The processing cost, around 35 yen/L, was equal to or less than current disposal cost. No difference was shown in the chisel and flank wear of machine tool after 100 holes drilling between the water-soluble coolants diluted with recovered water and service water. These facts indicated that the proposed treatment system must be an effective way to reutilize the water-soluble coolant as the diluent of renewal coolant.
