1. Introduction
Untreated groundwater and unpolluted lake waters
are usually free of toxic/mutagenic compounds. However,
it is becoming more and more difficult to find
unpolluted water resources for drinking purposes. To
improve its quality, surface water may be treated in
different ways. Several processes, such as sand filtration,
coagulation followed by filtration or activated carbon
filtration are the most commonly used technologies to
remove natural and synthetic organic compounds from
water. In recent years, new technologies are being used
