Single-Course English 5 ECTS

Recirculating aquaculture systems

Overall Course Objectives

To provide students with basic knowledge of the technology used in recirculating aquaculture systems. The course should enable students to describe the design and functional properties of individual components used in aquaculture with a high degree of water reuse.

Learning Objectives

  • Explain the parameters for water quality in aquaculture
  • Describe the mechanical, physical, biological and chemical processes and components used in a recirculating aquaculture facility.
  • Calculate the required dimensions of the central treatment components in a recirculation facility.
  • Account for the fundamental processes in biological filtration
  • Account for the function and theoretical background of the techniques used in water oxygenation and degassing
  • Explain the principles of sludge and waste water treatment.
  • Account for sources and composition of nutrients in wastewater from aquaculture
  • Account for methods to reduce nutrient loading from production in aquaculture
  • Account for methods and processes in denitrification

Course Content

Central processes in recirculation technology and the functional properties of working components. Water supply and quality, nutrient loading, particle removal, sludge and effluent treatment. Operational conditions. Nitrification processes and biofilter design. Denitrification processes. Chemical disinfection, UV and ozone treatment. Oxygenation and degassing. Dimensioning of pumps, pipes and fittings, calculating head loss.

Teaching Method

Lectures, guest lectures, group based problem solving and written assignment, excusion to aquaculture facilities.


We recommend taking 25331 and 25316 in the same semester.
This course provides students with competences relevant to UN SDGs, particularly #2 (Zero hunger), #12 (Responsible consumption and production) and #14 (Life below water)
