Attenuation of microbial and phyto-toxicity of OMW by daily treatment in soil slurry

Laboratory experimentation has shown that OMW polyphenols can be removed massively by one-day treatment in aerated soil slurry. The removal is mainly due to an abiotic reaction promoted by iron and manganese oxides generally present in the clay fraction of agricultural soils. A modest contribution of biotic mineralization has also been found for less reactive phenols. Such treatment substantially reduces microbial and phyto-toxicity of OMW without destroying the organic load. The resulting wastewater can be used for fertirrigation of poor agricultural soil, by exploiting the organic and mineral content of OMW without the restraints imposed by the presence of polyphenols in non-treated wastewaters. Scale-up of the treatment to the production rate of a small olive-mill and field application of treated OMW are subject of future research.
