Important announcement

Dear visitor,

Please note that this OpenCourseWare platform will be replaced at the end of 2026 by a new platform (under the same url ocw.tudelft.nl).

Courses and their contents that are currently available the platform will partly be migrated. URL’s for this content will change and content might be unavailable for some time. In addition, some courses will not be available anymore.

If you are linking to specific courses on this platform (for instance for your students), please take timely measures to avoid problems with access. Possible actions are:

  • Download the materials to your local platform (laptop, server)
  • For educators only (including TU Delft lecturers): Contact us at ocw@tudelft.nl and inform us what course you are using in what context (institute, program, period of use, number of students). We will research (in collaboration with the authors of the course) and decide if we will migrate the course, and if yes, can supply you with a new url.

Thank you.

D02a – Aeration / Gas exchange

Course subject(s) D02a – Aeration / Gas exchange

In this lecture, prof. Van Dijk introduces a typical treatment process in groundwater systems: aeration or better gas exchange.
This lecture deals with the theoretical backgrounds of gas exchange controlled by the equilibrium between gas and water, and the dynamics of gas exchange given by the kinetics and the mass balance.
Thereafter the practical applications are presented such as aeration in cascades, spraying and tower aeration/stripping.
