ObjectivesThe course intends to provide an understanding of systems for safe recycling of plant nutrients and organic matter from biological waste and wastewater to cultivation.
After completing the course, the student should be able to:
- describe the sources of biological waste and wastewater and explain the characteristics of the different flows,
- propose design criteria for safe recycling systems for plant and biological materials from biological waste and wastewater,
- describe the difference between microbiological and macrobiological treatment with regard to the biology and processes and the value of the products
- Describe the difference between aerobic and anaerobic treatment of solid and liquid waste, with respect to both biology and processes,
- Evaluate treatment systems for composting, anaerobic digestion and small scale wastewater, including source separated sewage systems, with regard to microbial risk and environmental impacts of the systems,
- suggest systems and processes that ensure that the recycled nutrients are properly hygienised, as well as describe factors that regulate the inactivation of pathogens,
- evaluate results from different environmental systems analyses and microbial risk assessments,
- write and orally present proposals for recycling systems for nutrition from biological waste and wastewater and describe the factors that regulate inactivation of pathogens.
ContentThe course combines theoretical learning in lectures with practical laboratory exercises to achieve an increased understanding of the subject. The practical exercises are a composting laboratory exercise, a computer exercise, a study visit to a waste facility and a project assingment on risk assessment.
The focus of the course is biological treatment, safe hygienic treatment, environmental assessment and microbial risk assessment of biological waste and decentralized wastewater systems. This is discussed in literature and lectures.
Lectures, literature, calculations and study visits cover amounts and compositions of different fractions of biological waste and sewage and how these can be treated in different aerobic and anaerobic processes for waste and wastewater. Examples of these treatment techniques are composting, fly larvae composting, anaerobic digestion, infiltration and drainage ponds. During the course, we go in-depth in the process microbiology, thermo- and process dynamics, dimensioning, emissions, resource utilisation, hygiene and practical implementation as well as the value of the products as feed and fertilisers. We also cover other parts of the return systems, such as collection, distribution and application.
Two laboratory exercises are carried out. In one of these, biological treatment is practiced. The other is a computer exercise in which an environmental system analysis is conducted. In a case study, application of microbial risk assessment is practiced. A compulsory study visit is carried out at a waste facility
Formats and requirements for examinationThe course is examined in written tests, written laboratory reports, written and oral project reports and a compulsory study visit.
For approved course, approved tests, approved reports and project reports are required, as well as approved participation in compulsory moments. Compulsory elements of the course are the implementation of and approved report from:
- projects in microbial risk assessment
- practical composting
- computer exercises in environmental systems analysis
Furthermore, participation in a study visit at a waste facility is required
- If the student fails a test, the examiner may give the student a supplementary assignment, provided this is possible and there is reason to do so.
- If the student has been granted special educational support because of a disability, the examiner has the right to offer the student an adapted test, or provide an alternative assessment.
- If changes are made to this course syllabus, or if the course is closed, SLU shall decide on transitional rules for examination of students admitted under this syllabus but who have not yet passed the course.
- For the examination of a degree project (independent project), the examiner may also allow the student to add supplemental information after the deadline. For more information on this, please refer to the regulations for education at Bachelor's and Master's level.
- The right to take part in teaching and/or supervision only applies to the course date to which the student has been admitted and registered on.
- If there are special reasons, the student may take part in course components that require compulsory attendance at a later date. For more information on this, please refer to the regulations for education at Bachelor's and Master's level.
