the aerobic granular systems represent a good alternative to substitute the conventional activatedsludge process in the treatment of industrial effluents due to the lower surface requirements. in this work the effluent from a seafood industry, characterized by a high variability and the presence of residual amounts of coagulant and flocculant reagents, was used to study the development of aerob...
