Objectives

The course aims at giving good knowledge on systems and technology for managing sanitation on-site sanitation systems and on how the resources in different wastewater fractions and sewage sludge can be utilised in a safe way.

On completion of the course the student should be able to

• analyse possibilities for resource utilisation from wastewater systems in the form of e.g. plant nutrition, water and energy
• analyse how different choices of system technology choices affect hygienic risk, environmental impact and sustainability
• describe various principles, methods and microbiological and chemical processes for on-site management of wastewater and sewage sludge as well as common goals for such management.
• propose and dimension systems for on-site wastewater systems and resource recovery.

Content

Subject content

The course focuses on the design and properties of small-scale wastewater systems, as well as resource recovery from plant nutrients, water and energy in different systems. The emphasis of the course is on systems relevant for Sweden, but systems relevant for low-income countries are also covered. Lectures cover: nature-like soil-based systems (sand filters and soil infiltration), simple anaerobic systems, source separating wastewater systems, surface and subsurface constructed wetlands. Both large- and small-scale processes for treating and sanitization of sewage sludge, faecal matter and urine for safe recycling are included. The requirements concerning concentration, pathogens, logistics etc. for recycling plant nutrients and/or water are included in the course, as are the impacts of the system on resources and environment.

Learning activities

The course uses different teaching methods to promote students' learning and discussions through lectures, exercises, literature studies and assignments. In exercises, the dimensioning of different treatment systems and calculation of the systems' resource impact are practiced. The course also includes study visits to some small-scale sewage systems.

The course focuses on the following general competencies:

• problem solving
• critical thinking
• scientific methods
• creativity.

The following activities are compulsory: Exercises and study visits.

Collaboration with the surrounding society takes place through study visits.

Examination Formats and Requirements for Passing the Course

The forms of examination are a written exam, assignments and active participation in mandatory sections. Requirements for an approved course are an approved written exam, an approved assignment and approved participation in compulsory activities.
