Disinfection, Adsorption and Natural Processes for Water Treatment

IHE Delft water treatment

Target Audience

Professionals dealing with engineering, management and education in the fields of water supply and wastewater and urban infrastructure will benefit greatly from this short course. It is also helpful for postgraduate students in environmental engineering. Participants from government organisations (such as local administrations and national agencies), non-governmental organisations and the private sector are encouraged to join. This course is ideal for practicing engineers who are working in the water supply and sewerage systems.


The aim of this course is to present and exchange state-of-the-art knowledge and experience on the technologies and design practices of conventional water treatment systems.

Course content

The course covers some of the unit processes of conventional surface water treatment. The following unit process will be explored in detail through lectures, laboratory sessions and workshops:
– Disinfection: Basic principles of disinfection; chemical disinfection; disinfection by products; ozone disinfection; UV disinfection.
– Adsorption: Theoretical background of adsorptive processes.
– Activated carbon: Granular and powdered activated carbon, modelling and design.
– Chemical softening: Principles of chemical softening and sludge blanket softening; design and operation of pellet-softening and membrane softening plants.
– Ion exchange: Ion exchange resins (selectivity, column operation, regeneration of resins and applications).
