The Terephtalic acid effluents are considered as a difficult to treat stream and this aromatic acid itself has been reported as inhibitory to anaerobic sludge activity. Usually the difficulty is overcome by the use of special reactor designs and/or neutralization reagents. In this work, we focus on clarify the real limitations for anaerobic treatment imposed by acidity, solubility, and biodegradability restrictions. Our findings indicate the treatment is not straightforward but possible, particularly if some considerations are taken. The critical control parameters are the reactor pH, and operate at or above a minimum percentage of COD removal. The organic acid solubility is not a limitation. (Résumé d'auteur)
