conventional and contemporary methods for water treatment: from wastewater to ultra pure water

Abstract

In this paper modern methods and techniques for water purification are described. Good water quality and the rational use of water are an absolute need of the new millennium. The quality of life depends on water quality. Although it is an ecological priority to prohibit the contamination of water, it is a responsibility for environmental engineers and chemists to develop and apply effective methods for water purification. Beside well-known methods and techniques, it is necessary to create new methods for water purification and treatment. Water recycling is especially important. Plants with membrane separation technologies enable savings in fresh water with high efficiency. Methods for monitoring and controlling processes and water protection should be developed simultaneously with the development of techniques for the methods for purification.
