Abstract

SANCHEZ GONGORA, María Antonieta et al. Preliminary evaluation of field parameters at an anaerobic biodigester designed for the treatment of wastewater. Rev. colomb. biotecnol [online]. 2016, vol.18, n.1, pp.173-184. ISSN 0123-3475.  http://dx.doi.org/10.15446/rev.colomb.biote.v18n1.57725.

The anaerobic biodigester analyzed in the present study was designed for the treatment of domestic wastewater in a test restroom, characterized by its continuous flow, low organic load and a four-stage processing system. The value of the prototype under research consists in the real daily conditions under which it was tested. The first stage consisted of the site selection, and the manufacture of a waterproof iron reinforced cement prototype, with a 1m3 loading capacity. At this stage, during the period from august to december 2011, the reactor was inoculated with organic matter originating from the aforementioned restroom discharges. The evaluation of this stage consisted in taking measurements of the following field parameters: pH, electrical conductivity, sedimentable solids, and inflow and outflow temperature along the system. These records substantiated the behaviour of the processes within the digester during the starting phase. The results obtained through these determinations at both the biodigester entry and exit points are respectively: pH (8.03; 8.43), electrical conductivity (1510.83 µS/cm; 1207.00 µS/cm), inflow and outflow temperatures (19.2°C; 20.1°C), sedimentable solids (144.5mL/L; 0.02mL/L) and dissolved oxygen (4.5992 mg/L; 0.1924 g/L). These data provided a starting point for the treatment of domestic wastewater.

Keywords : wastewater; treated water; biodigestion; continuous flow biodigesters; digester; psychrophilic temperature.
