RESALTTECH - Concentrated saline rejection treatment: Environmental Technology using a non profitable solid waste as energy source
The paper industry generates solid waste and residual effluents that have a significant impact on the environment. It is also the second biggest water consumer in Spain, representing 16.3% of total industrial water consumption. Recycling of water is difficult because of the salinity of the outgoing water effluents, which affect the quality of the paper. The project will design and construct a new closed-loop water system prototype for the paper industry, with the following objectives: (i) conversion of the residual flow (brine), into a by-product, where the salt could be reused in other applications such as tanneries; (ii) energy production by the solid waste generated by the process; (iii) reduction of water consumption through reuse of water in the paper production process.
