Abstract
A laboratory-scale anaerobic fixed-bed reactor, operating at ambient temperature (30 to 35°C), was used to treat sewage water from tourist areas in Cuba at hydraulic retention times (HRT) ranging from 4 to 72 h. The total chemical oxygen demand (T-COD), total biological oxygen demand (T-BOD) and total suspended solids removal varied between 30 and 80%, 40 and 95% and 25 and 80%, respectively. Total and faecal coliforms were reduced by 98.1 to 99.9% and by 99.0% to 99.9% respectively, despite the marked decrease in HRT from 72 to 4 h.
