Abstract
Effluents from a trout farm in Brescia province, Italy, were tested for conformity with the law. It was found that the water discharged from the tanks was within the limits permitted for discharge into rivers but that the sediment exceeded the limits. A primary treatment of the separated sediment removes purified water to be mixed with other water discharged from the tanks; the remaining sediment is then screened before composting. Given the small quantities of sediment involved, the entire purifying installation can be buried into the ground to avoid damages to landscape.
