Multilayer alkaline earth chemical pellets for on-site urine treatment

Topic: Technology

Description:

The sanitation sector is increasingly focusing on resource recovery as a way to adapt to environmental challenges. At the same time, the world needs flexible and safe sanitation systems that can be scaled-up quickly to service the billions of people currently lacking access to a proper toilet. A new sanitation paradigm is emerging with flexible, decentralized solutions that recover resources in the form of nutrients, water and energy for use in a variety of productive sectors.

The overall goal of this PhD project will be to develop the next generation of treatment technologies for source-separating sanitation systems, with focus on recycling human urine. The project will develop a key technology that could accelerate implementation of such sanitation systems in real-life settings – a unique on-site reactor that chemically stabilizes nutrients excreted in urine, so that it can be transported without loss of nutrients for further centralized treatment (e.g., concentrated by alkaline dehydration to produce a solid fertilizer). The ambition is to transition urine source-separation from a niche, single toilet technology (e.g., at Scandinavian summer houses) to a mainstream community-scale technology (e.g., multi-story buildings). Because urine is safely converted to fertilizer, nutrients will never reach wastewater treatment plants or water recipients where they cause eutrophication.

Qualifications:

Required:

  • Master of Science with a focus on environmental-, chemical-, civil- or process engineering or its equivalent.
  • Good knowledge of English in speech and writing.

Meriting:

  • Knowledge in inorganic chemistry
  • Modelling of chemical processes
  • Knowledge and experience working with wastewater systems
  • To be able to communicate in Swedish

Great emphasis is placed on personal qualities, such as the ability to work together, analytical and problem-solving ability as well as the ability to work independently.

Place of work:      

Uppsala

Forms for funding or employment:

Employment 4 years

Starting date:

According to agreement.

Application:

The application must contain the following:

  • An Essay summarising and reviewing literature on the technology – alkaline urine dehydration (maximum 2 A4 pages);
  • A Letter of Motivation, describing the applicant’s previous academic and professional experience and motivation for applying for this position (maximum 2 A4 pages);
  • Curriculum Vitae
  • Copy of degree certificate including transcript of academic records
  • Copy of degree thesis
  • A list of two reference persons familiar with the applicant’s qualifications

Click the “Apply” button to submit your application. The deadline is 2023-03-08.

To qualify for third-cycle (Doctoral) courses and study programmes, you must have a second-cycle (Master’s) qualification. Alternatively, you must have conducted a minimum of four years of full-time study, of which a minimum of one year at second-cycle level.

Applicants will be selected based on their written application and CV, degree project, copies of their degree certificate and transcript of records from previous first and second-cycle studies at a university or higher education institution, two personal references, and knowledge of English. More information about the English language requirements can be found here: www.slu.se/en/education/programmes-courses/doctoral-studies/new-doctoral-students/english-language-requirements/

Please note that applicants invited to interview must submit attested copies of their degree certificate, a transcript of records from previous first and second-cycle studies at a university or higher education institution. Applicants who are not Swedish citizens need to submit an attested copy of their passport’s information page containing their photograph and personal details.
