A short term solution for the treatment of dairy waste water is discussed. Discharge rate is 500 m3/day with a high organic load (2,750 kg COD/day). Low capital investment (US 330,000) and operational (US 0.55/m3) costs were required which ought to be competitive with current market prices but within the official environmental norms imposed by the national agency SEDESOL. The problem was solved by remodelling existing lagooning facilities which were operating below the official norm. Local technology was used with the exception of aeration equipment. The system was made of a clarifier, an anaerobic lagoon, an intermediate aerobic lagoon and an effluent polishing lagoon with water hyacinth. Design and supervision was dones by UAM-Iztapalapa personnel. Construction and operation by the cheese factory "El Sauz, S.A. de C.V.". (Résumé d'auteur)
