Removal of organic matter and toxicity in an upflow immobilized biomass anaerobic reactor treating hospital wastewater: preliminary evaluation

The aim of this research was to evaluate the performance of an Upflow Immobilized Biomass Anaerobic Reactor (UIBAR) treating real hospital wastewater. The organic matter removal and the toxicity were assessed through COD, UV254nm and the measure of the growth inhibition of onion roots (Allium cepa L...
