The consortium has already tested INCOVER technologies individually at lab scale. The innovation of INCOVER project comes from the combination of all INCOVER technologies, for a bio-production and resource recovery-based wastewater treatment. The description of each technology is as follows:
The maximum hydrolysis efficiency for microalgae will be achieved by means of thermal pre-treatment in case study 1. This pre-treatment will be operated under the optimal conditions previously obtained in pilot scale studies
Biogas production from different biomass can be improved by several pre-treatments in order to lyse biomass cells further to facilitate hydrolysis (Carrère et al., 2010). In the case of microalgae, physical and thermal pre-treatment techniques, previously tested at pilot scale by INCOVER consortium (Alzate et al., 2012; Passos and Ferrer, 2015), have provided methane productivity (LCH4/kgVS algae) increases of 60-100%.
At El Torno WWT plant, two different approaches will be tested:
