Clean water and environment are better than the basic human needs for life, but water and biological pollution due to human activities have disrupted this issue. Also, the lack of safe drinking water in the country reinforces the need to treat industrial and urban wastewater and return it to the consumption cycle of industrial and urban production. Another thing to mention is the polluted water from the output of manufacturing industries and the entry of this polluted water into the environment and in some cases the seas, which causes biological pollution for living organisms, especially humans, for this reason, industrial and urban wastewater treatment is very important. is placed Different methods are used for industrial wastewater treatment, the disadvantages of which are the use of chemicals and the production of sludge and bad smell during the treatment process, as well as spending a lot of time for treatment. Therefore, industrial wastewater treatment to remove heavy metal pollutants such as arsenic; Desulfurization and removal of pathogenic microorganisms in them and preparation of water with the least biological contamination using cavitation technology have been studied.
