Learning objectives
Upon completion of this course, the participants will be able to:
- assess if given groundwater is aggressive against materials used in water supply system and propose appropriate neutralisation methods;
- describe importance of groundwater as a source for drinking water production and assess overall quality of a given groundwater;
- establish appropriate treatment approach for groundwater containing commonly occurring impurities and pollutants (iron, manganese, ammonia, fluoride, arsenic, hydrogen sulphide and nitrate);
- explore advanced groundwater treatment approaches applied in The Netherlands and in Belgium for removal of emerging pollutants.
Course content
Groundwater (GW) presents more than 95 % of Earth’s liquid freshwater, thus being a much bigger source of water than surface water. Aquifers provide natural protection from contamination, making GW:
- cleaner | safer than surface water;
- mainly pathogens-free,
- having constant | good quality.
Consequently, drinking water production from GW requires low capital and operational costs. It is also available close to demand points, which makes it the major source of drinking water in developing world.
However, developing countries lack the knowledge | expertise to exploit GW for drinking water production. Overcoming this challenge is the main goal of this course.
IHE, with experts from the Dutch water industry, has a long history in innovative research in improving quality of groundwater (PhD studies, >50 MSc studies, innovation of the year reward), and can therefore provide the needed expertise to participants, in particular from developing countries, that are underusing their natural resource – groundwater.
Groundwater resources and treatment course covers the following topics.
Introduction to course
- Reasons GW is one of the major water sources for drinking water production;
- advantages of exploiting GW as a drinking water source.
Aggressive properties of water & neutralisation techniques
- Problems caused by water that has aggressive (corrosive) characteristics;
- methods to determine aggressivity of water;
- methods to reduce | eliminate aggressive properties of water (neutralisation methods).
Groundwater quality
- Sources of impurities and pollutants in GW;
- chemical and physical characteristics of GW.
Aeration & Gas transfer
- Purposes of aeration applied in GW treatment;
- introduction to different aeration systems usually applied in GW treatment.
Conventional groundwater treatment
- Origins and problems caused by the presence of iron, ammonium, manganese and hydrogen sulphide in GW;
- conventional methods for removal of these parameters from GW;
- experiences from field pilot and full-scale groundwater treatment plants;
- research at IHE on iron and manganese removal.
Arsenic, fluoride & nitrate removal
- Origins and health effects of arsenic, fluoride and nitrate contamination of GW;
- methods for removal of these parameters from GW intended for water supply;
- innovative research on adsorptive arsenic and fluoride removal technologies at IHE Delft.
Advanced groundwater treatment in The Netherlands.
- Removal of natural organic matter from GW;
- river bank filtration and artificial aquifer recharge.
The participants will be introduced to the above topic through lectures, design exercises, lab sessions and field trip(s).
