MIDES showcases microbial desalination progress at China conference
IMDEA Water presented the latest advances in microbial desalination at the 15th IWA Leading Edge Conference on Water and Wastewater Technologies in Nanjing, China, on 24 – 31 May. The presentations included research by the MIDES consortium working for the past 2 years towards the first demonstration site in Denia, Spain, in April 2019.
IMDEA researcher Juan Manuel Ortiz (right in photo) highlighted the technical advancements in two presentations: Anaerobic Wastewater Pretreatment As Fuel Production Stage For Microbial Desalination Cells – and – Microbial Desalination Cell For Brackish Water Desalination Powered By Energy Contained In Wastewater.
The IWA LET conference is a reference point in the field of new water treatment technologies. The gathering serves as a platform to exchange ideas on the future of water technologies, the efficiency of the purification processes, challenges related to climate change, and the sanitation challenge in developing countries.
Recent MIDES technical developments include:
- MDC pilot plant design and preparations of the Demo Site 1 in Denia, Spain, are on schedule to begin in April 2019.
- The MIDES consortium is focused on the MDC pre-pilot stack assembling at IMDEA Water in Madird. Optimum carbon electrodes and membranes have been developed and characterized – and are ready to be tested in the MDC pre-pilot unit
- Several wastewater sources have proved feasible as a fuel feed in the bioanode (VFA generation) to power the MDC. Best practices for wastewater conditioning have been defined for pilot scale in Denia. And different membrane pre-treatment technologies have been implemented and optimized to guarantee the wastewater and saline stream quality suitable to be fed into the MDC and RO treatment.
- Automatization and control system for MIDES technology has been defined to be integrated in the MDC pre-pilot unit constructed.
- First version of MIDEs model, library and IPSEpro simulation tool have been developed. These will be fine-tuned based on the inputs from MIDES units and integration operation.
