Examples of Radiation Wastewater Treatment Implemented in Various Countries

With the increase in population in many of the big cities and the growing industrialization in many countries, the pollution load on the environment is increasing. Of particular concern is the waste containing pathogenic bacteria, parasites and viruses. Reduction of non-organic and organic pollutants as well as destruction of bacterial flora became very important and urgent practical issue. For this reason, research in various countries has been exploring new effective and economical techniques for wastewater treatment. One of the techniques that have been recently implemented in several countries is the utilization of ionizing radiation for wastewater and industrial wastes treatment. High power accelerators are used as well-controlled sources for radiation treatment of wastewater. The radiation treatment of sewage sludge offers an efficient, simple and reliable method to produce pathogen-free sludge, which can be further upgraded to produce bio-fertilizers. Examples of electron beam systems used for wastewater treatment at some countries are presented.
