The coordinated project TREASURE has as main objective the development and evaluation of a modular treatment train comprising two lines operated in parallel to valorise and treat the wastewater (WW) produced in the fish-canning industry.

Biogroup will be responsable of the Sub-Project 1 TECHNOSALT "Unravelling salt and temperature effects on the performance of an integral modular system for fish canning wastewater treatment and valorisation" Its objective is the development and evaluation of a modular treatment train comprising two lines which operate in parallel, to valorise and treat the fish-canning wastewater. TECHNOSALT will contribute to achieve this objective by means of the following particular objectives:

i) to evaluate the effect of salinity (5-35 g NaCl/L) and temperature (10-25 ºC) on the activity of different bacterial populations;

ii) to optimise the removal and valorisation (to obtain biopolymers) of the organic matter;

iii) to optimise the nitrogen removal (via nitrite);

iv) to optimise an integral modular treatment comprising two lines of valorisation, of the fats, oils and grease fraction (FOG), and treatment of the remaining fraction; and

v) to evaluate the treatment train by means of the Life Cycle Assessment (LCA).

These particular objectives will provide information regarding the operation of the reaction systems that will be evaluated by the group of the Universidad de Granada (UGR) from the point of view of the microbial population dynamics in the subproject 2 MICROSALT.

Only combining the results of the reactors operation (TECHNOSALT) and the microbiological information (MICROSALT) the optimal operational conditions, to avoid destabilization issues and to promote optimal performance, will be defined; and as a consequence the environmental impact will be diminished.
