At cubans universities over the 65 % of students are grant holders and special attention lends itself to the steps of domestic waters generated in communities and university permanences. This work presents the removal of the organic matter in the university community's domestic waters Antonio Maceo of the Universidad de Oriente utilizing, to scale of laboratory two systems: UASB reactor and anaerobic lagoon. The anaerobic systemsevaluated attained a superior COD removal to the 70 % and decrease of bacteria's total coliformes from 72x105 NMP/100 mL to 16 NMP/100 mL. The clarification with alum improves the esthetic characteristics of the outflow. Anyone of variants (UASB or anaerobic lagoon) can be applied for the removal of the organic matter in the university community's domestic waters.

Keywords : wastewater; university campus; anaerobic technology; UASB reactor; anaerobic lagoon.
