Activities in the Spanish Living Lab
The TWIST Spanish Living Lab has an innovation focus in wastewater treatment and reuse and has been named Open Water Living Lab, OWL2. OWL2 is already working and testing innovative solutions for wastewater treatment, some of them resulting from synergies with other projects. Here we summarize some of the pilots and prototypes that are being developed in TWIST Spanish Living Lab, OWL2: Low carbon wastewater treatment systems OWL2 will host three systems for the treatment of low carbon wastewater: EXTensive systems based on the sun, improved in performance and environmental footprint, with a surface requirement below 1 m2 / PE. Membrane Aerated Biological Reactor pilot OWL2 has tested, during a year, a pilot from the Israeli company Fluence, which treatment system is the MABR (Membrane Aerated Biological Reactor) technology, based on passive aeration, that is, the diffusion of oxygen through membranes using a low pressure aeration flow. Drying sludge with solar energy prototype OWL2, completed the construction of a prototype for drying sewage sludge and leachate through the use of concentration solar technologies. Forced aeration Constructed Wetland with Filtralite-P substrate for phosphorus removal prototype To test the behavior of a sustainable purification system using air flows, clays and plants, to […]

Bioelectrochemical treatment wetlands (METland®) in OWL2
Bioelectrochemical wetlands for treating wastewater (METland®) for small populations are being tested and validated in the facilities of the Spanish OWL2 in CENTA. The METland® (a registered product) is a concept developed by the start up METfilter S.L., a technology-based company established by IMDEA Water and CENTA Foundation which objective is to design, construct and market water purification systems based on the principle of microbial electrogenesis. METfilter has solutions and applications for municipal and industrial wastewater treatments. How does a METland work? In this video, researchers from the Bioe group at IMDEA Agua explain the fundamentals of the iMETland project, in which this concept that combines the principles of treatment wetlands and microbial electrochemistry has been developed. Several units are already operating at different locations and can be integrated into small communities or isolated households, with a plant-based solution that increases their visual appeal. To know more about the iMETland technology you can also see the interview to Dr. Abraham Esteve HERE. CENTA has been involved since its inception in the development of bioelectrogenic technologies using bioelectrochemical treatment wetlands. Among other initiatives, CENTA has participated in the H2020 iMETland project, which has been chosen among the top three in Europe […]

Algae-bacteria mixed culture photobioreactor in OWL2
The Algae-bacteria mixed culture photobioreactors are based on a mixed process in which the oxidation of organic matter and the removal of nutrients (N and P) simultaneously occur, without the need for aeration, and therefore with minimal energy consumption. The photo-bioreactor is a raceway or HRAP (High Rate Algal Pond) reactor, the most applied when it comes to cultivating microalgae and the most suitable to adapt them to wastewater treatment. This consists of a rectangular section carousel oval channel through which the residual water circulates thanks to the impulsion received by a set of blades mounted on a horizontal axis, They work at depths ranging between 10 and 40 cm, so that access to light is maximized, and they operate with residence times of between 3 and 10 days, depending on the availability of light. This system is appropriate for populations over 200 h.e. The photobioreactor prototype has been developed by CENTA and the University of Cádiz in the framework of IDIaqua project. More about IDIaqua project IDIaqua project, an international project to promote RDI of excellence for water purification in small urban agglomerations. IDIaqua is financed by the European Union Spain-Portugal POCTEP 2014-2020 cross-border cooperation program, through FEDER funds. […]
