ELSEVIER publication proves emerging pollutants do not affect the performance of PPB

We want to share a new research article, published in the ELSEVIER Journal of Hazardous Materials written by scientists from the DEEP PURPLE consortium.

These results support the use of phototrophic bacteria technologies for resource recovery with low emerging pollutants contamination of the products. Also, they demonstrated that the biological treatment system (photo-anaerobic membrane bioreactor) was able to achieve remarkable removals of organic matter (chemical oxygen demand) and nutrients including nitrogen and phosphorus.

Video explaning the use of PPB in WWTP

The University of Rey Juan Carlos in cooperation with aqualia created this beautiful video for their joint project Bio3 to showcase the use of the purple phototropic bacteria in waste water treatment plants to extract valuable compounds out of waste and create energy for the plant and further use.

– To operate and maintain a pilot-scale bio-refinery consisting of:
1. A pair of 0.5 m3 photo-bioreactors, where purple phototrophic bacteria will evolve
2. Pumping units for inlet, outlet, and recirculation of the plant
3. A pair of settling units
4. A microwave volumetric heating unit for biomass pasteurization
5. A decanter for biomass dewatering
6. A sludge infrared drier
– To analyse all the macroscopic parameters for the operation of the pilot-plant, including: COD, VSS/TSS, N and P forms, among others
– To perform specific analysis on the metabolism of purple phototrophic bacteria, including batch and short-term continuous tests at laboratory scale
– To write scientific documents and preliminary reports

– A one-year contract that may be extended based on milestones evaluation.
– Competitive salary.
– The job position will have a first milestone in August 2020, where it will be checked whether a PhD position is offered to continue with the work for up to 3 years.
– Working in a high-level scientific-technical environment, with an emerging technology where the URJC is a pioneer in the EU.

– MS in chemical engineering, environmental engineering, environmental biotechnology, wastewater treatment or similar
– Experience on pilot-plan operation
– Experience in biological wastewater treatment
– Availability to travel locally (surroundings of Madrid)
– To be in a good fit to operate large and heavy equipment
– Proficiency in English
– Immediate incorporation.

– Experience on modelling/simulation of biological processes
– Experience on massive sequencing analysis (metagenomics, metaproteomics)
– Valuable Spanish language.
– Open mind
– Proactivity
– Team worker
– Problem-solving attitude
