Gathered in Malmö to celebrate the 4th REWAISE General Assembly

Last October, the REWAISE team met in Malmö, Sweden, for the 4th General Assembly to discuss and review the progress of the project, present the technologies under development, and visit the facilities that the Skanne’s Living Lab have in the cities of Malmö and Lund. 2 days of meetings organized by VA SYD and the Swedish team, in which the entire consortium participated actively.

REWAISE Consortium meets during the 4th General Assembly

The meeting started with a project overview and results by the project coordinator, Frank Rogalla, R&D director in Aqualia. The morning continued with the presentation of several technologies that are being developed, tested, and implemented within REWAISE. Technologies such as the AnMBR, a membrane reactor for anaerobic nutrient and energy recovery tested in a major car factory in Vigo, allow to convert organic matter directly to biomethane, without wasting electricity on aeration.

Also, remote valve actuators technology was presented, this development resulted in increased speed response, cheaper remediation as it does not need civil works, a longer life battery was installed, and reduced Work in Progress as technicians are able to focus on planned work. Another technology presented was IWAN solution, that is supported by an autonomous sewer flow control system to reduce overflows, will offer an equivalent spill of 46% per year reduction while reducing CAPEX by 80%, compared to a conventional solution.    

The next technology presented was Ammonia recovery, where OTAR (Organics Thermal Ammonia Recovery) was described. Some of the main characteristics of this pilot are that the stripping and recovery of ammonia is a non-biological process, the plant may be started and stopped automatically, and it can operate using various energy formats such as biogas, natural gas, exhaust heat, etc. Also, another kind of recovery technology was presented, in this case Brine recovery. The aim of this technology is to separate, concentrate and recover minerals from seawater, to extract Limestone, Gypsum, NaCl, and Mg (OH)2. Now, NaCl and Calcium ponds have been designed after simulations were developed to achieve the required mineral concentration, and target Concentration Factor (CF), depending on weather conditions and evaporation rate (mm/day). Finally, membrane filtration and rainwater harvesting were presented, showing the actual pilot installed in Sege Park, Malmö, to recover rainwater, and use membranes to reuse it. This plant operated for 19 consecutive days with an average flow of 100 l/h, and a specific flow rate of 25 l/m2*h (4 m2 membrane area). Also, this plant showed good reduction rates for COD, heavy metals, ammonia, and bacteria.

Visit to REWAISE project facilities in Sweden

In the afternoon, there was a tour visit to the REWAISE pilot plants in the cities of Malmö and Lund. The consortium could visit the Källby Sewage treatment plant in the city of Lund, the Sege Park Living Lab in Malmö, and the urine sorting toilet at VA SYD headquarters.

On the second day of the meeting, we inaugurated together with WIN Innovation Platform the REWAISE’s WINcubator, an incubator to enable new technologies to enter the water market faster. The launch event, entitled “Resilient Water Management with Global Water Networks“, held at the Media Evolution City in Malmö, was attended by innovative technology companies from the United States, Norway, United Kingdom, Poland, Spain, Denmark, the Netherlands, Sweden, Croatia, and Saudi Arabia.

WINcubator first meeting

It was a hybrid meeting where innovative solutions for water nutrient recycling, brine extraction and decentralized water reuse systems were introduced, as well as a robot for pipe condition detection and network computer analysis.

The 4th General Assembly concluded with the workshop on Competency Groups and Living Lab Assessment led by ENoLL,  WE&B and the Centre for Agroecology, Water & Resilience from Coventry University. Previously, the consortium enjoyed a master class on the experience of Botnia Living Lab, focused on human-centric research, and the development and innovation of new ICT-based services.

Apart from the technical sessions and pilot plants visits, there was also time for networking and sharing fun experiences in Malmö. Thanks to the VA SYD colleagues and the entire Swedish team for such a well-organized event.
