n recent years, the UAB has seen recognition for its efforts in promoting quality in teaching, in attracting international talent and in obtaining a growing impact in research, together with a progressive improvement in its classifications in the most prestigious and influential international rankings. Thus, the UAB is well as occupying an outstanding position among Spanish universities in world rankings such as the QS World University Rankings (QS WUR), the Times Higher Education World University Rankings (THE WUR) and the Academic Ranking of World Universities (ARWU). It also ranks as one of the best young universities according to specific rankings made for universities less than half a century old by QS and Times Higher Education.
We are in continuous development of novel inventions in many fields, among others, in environmental and waste management.

Mainstream Sewage Nitrogen Removal with Anammox: Low ammonium/temperature not an impediment
The most sustainable (energy-neutral) wastewater treatment plants that are just starting to be developed are using Anammox for nitrogen removal. The main challenge for the success of the treatment is the difficulty of maintaining stable the nitritation process, since nitrite-oxidizing bacteria (NOB) may develop in such a granular sludge, producing nitrate, competing with anammox for nitrite and reducing the efficiency of the treatment considerably. We propose that partial nitritation could be achieved in a separate reactor where our technology will be in charge of maintaining partial nitritation without nitrate production (i.e. repressing NOB activity), thus enhancing the good efficiency of the nitrogen removal for main stream.
INNOVATIVE ASPECTS AND APPLICATIONS
-Applicability at full scale in municipal treatment plants (control set on side stream with just 1.0% of main stream)
-Long term stable maintenance of nitritation process at typical operating conditions in WWTP(T:8-35ºC, ammonium concentration :30-100 g N/m3 , COD concentration : 1-125 g/m3).
-Discharging buffer tank in anaerobic digester from which the flow-rate of reject is regulated and used for control purposes.

A method and a system for enhancing Nitrogen removal in a GSBR and computer program
Aerobic granular sequencing batch reactors (GSBR) have been successfully used for the treatment of municipal and industrial wastewater effluents. To date most of the efforts were focused on understanding the behaviour of the GSBR, but not in finding the best practical strategy to be implemented with the aim to improve the N-removal. To that end we developed a system for enhancing N-removal in a GSBR by controlling the dissolved oxygen (DO) by means of a closed loop based, comprising DO set point value automatic calculation (computer program) depending on ammonium concentration measurement at the end of the cycle. N-removal efficiency after the activation of the control strategy increased from 48% to 75% during the first 36 hours and it remained stable during the next 36 hours.
INNOVATIVE ASPECTS AND APPLICATIONS
-N-removal higher than 70 % despite oscillations of the amonium in the effluent or any other disturbance in variables such as the granule size, influent C/N ratio or NLR.
-Reduced aeration costs. DO concentrations lower than 2 mg O2 L-1.
-Maintains the normal cycle of the GSBR
-Robust and long term operation control.
-Only DO set point is directly manipulated.
-Automatic calculation of the DO concentration set-point value by computer program.

Metamaterial UHF-RFID Near-field Antenna
An electric near-field antenna based on metamaterial structures, compatible with far-field tags, has been developed in order to provide a solution to this limitation. The use of this device at POS allows for a fast checkout and fast inventory process, being all items tagged uniquely with one far-field UHF-RFID tag.
INNOVATION ASPECTS AND APPLICATIONS:
> Fast checkout: All items read and security disabled simultaneously.
> POS area perfectly defined: only desired items are detected.
> Items labeled with only one far-field, long read-range, tag for all applications (payment, inventory, security…).
> Detection for any tag orientation.
> Very low far-field radiation.
> Low-cost fabrication using PCB standard processes.
