The Life-ANADRY project has completed the action related to the installation the prototype in Alguazas WWTP located in Murcia, Spain. The prototype was tested previously in the laboratory prior to the implementation in order to verify the functions of the all elements. At this moment, the prototype is functioning under the optimum conditions for the anaerobic digestion (AD) process.
For its installation, the prototype was filled with the thermophilic inoculum, then it was be heated until it reached the target temperature (55ºC). The reactor is kept at that temperature during this period. After that, dewatered sludge is loaded in a semi-continuous mode until achieving a hydraulic retention time (HRT) of 20 days.
Implementation of LIFE-ANADRY project at the pre-industrial scale will be placed in a 20 m3 cylindrical reactor with a capacity of treating up to 3 tonnes/day. The system will be run under dry or high-solids conditions, with inflow sludge concentration ranging from 15-20% Total Solids (TS), and it will be operating at mesophilic and thermophilic temperatures. Moreover, the influence of the HRT on process performance will be studied in terms of sludge stabilization, pathogens elimination and biogas production.
