It has recently been reported1,2 that monovalent copper ions have the ability to destroy microorganisms, bacteria and fungi. The monovalent copper ion is unstable in water and without a suitable environment will undergo self-redox oxidation, in addition the monovalent copper ion reacts rapidly with molecular oxygen, so the use of monovalent copper ion for disinfection poses a technological challenge. In this study, we will present water disinfection systems that maintain an effective dynamic concentration of monovalent copper ions sufficient for water disinfection. We will present three different water disinfection systems suitable for batch and continuous disinfection. The first system is based on an ointment that releases monovalent copper ions to the solution (inspired by a patent3), the second in the form of a colona that in the first part filled with an ion exchanger loaded with divalent copper ions and in the second part metallic copper and the third based on copper electrodes. The results of the study show that it is possible to treat wastewater containing microorganisms with the copper-based system. In addition, the quality of the water that had been obtained after the treatment is suitable for use in agriculture in accordance to the Israeli regulations |
