Abstract: The trend of the last decade has been significantly associated with extreme drought periods. The logical consequence of such periods is lack of water to supply population with drinking water. This fact causes not only thinking about more efficient use of drinking water, but also pressure on big industrial enterprises that need water in large quantities. Without drinking and process water they often cannot ensure adequate operation. During extreme drought periods public health authorities limit water supply to such businesses so that there is enough water for households. These companies are therefore looking for “new” water sources. One of these essential sources of water is purified wastewater, which is currently considered a waste, not a potential source. Thanks to modern 21st century technologies such as membrane filtration and sorption using granulated active carbon, purified wastewater can be treated to a very high quality.

Key words: water reuse, water treatment, wastewater treatment, membrane separation, active carbon
