GONZALEZ MANOSALVA, José Luis; MEJIA RUIZ, Roberto  e  MOLINA PEREZ, Francisco. CONCEPTUAL DESIGN OF AN EXPERIMENTAL HOUSEHOLD WASTE WATER TREATMENT PLANT ADDRESSED TO MUNICIPALITIES WITH A POPULATION LOWER THAN 30,000 INHABITANTS. Rev. ing. univ. Medellín [online]. 2012, vol.11, n.21, pp.87-100. ISSN 1692-3324.

Conceptual design of an experimental waste water treatment plant for populations lower than 30,000 inhabitants is presented. The design integrates six interconnected treatment systems, including conventional and non-conventional systems with final disposal of the effluent to a water body or slow infiltration in the soil, complying with Colombian norms in force. The process included a state-of-the-art revision, design of this kind of plants (such as Carrión de los Céspedes in Andalucía, Spain; UFMG/COPASA plant in Minas Gerais-Brazil), works conducted in Colombia (IDEAM-CINARA-UTP), and tests performed by Madera, Silva, and Peña from CINARA in a pilot plant. Area estimated for construction of systems proposed reaches 18,000 m² and fixed costs for construction of the plant is estimated in 850 million Colombian pesos for treating a 1.5 l/s flow of household waste water.
