Summary

Anaerobically stabilized effluents of dried vine fruit industry were successfully treated in earthworm filters. The species L. rubelus was used. At COD loadings of up to 0.2 Kg COD/m2d the reactors responded well for an operation period of 15 months when experiments ceased. COD removal was 95% for loadings of 0.10 and 0.15 Kg COD/m2d. Earthworm biomass seems to be in its upper bearing capacity of approximately 2 Kg/m2 and did not increase seriously with time. Temperature change did not have any counter effect on the process.
