【 摘 要 】

Water is essential in nature for the survival of all life with significant environmental and economic contribution to the world. The gradual increases in water demand and consumption have led to the discharge of inadequately treated wastewater, thereby, deteriorating water quality and triggering worldwide water quality problem. Water quality is determined by different parameters. In particular, electron density and dissolved oxygen (DO) level in water are important in monitoring and controlling the water property and quality, since both of them are associated with various chemical, biological, and physical processes in water treatment. This project developed a method to increase electron density and dissolved oxygen level in water using principle of reversed electric motor. The essential requirements to achieve this principle are magnetic field, mechanical motion by force, and electron generation. The treated water's pH, conductivity, and dissolved oxygen level showed increment of 0.40, 0.05 μS/cm, and 2.7 % saturation (0.22 mg/L), respectively whereas its oxidation-reduction potential (ORP) showed a decrement of 94 mV, indicating the increment of electron density and dissolved oxygen level in the magnetic treated water. The enhancements of these parameters are highly desirable in the applications of medical treatment, wastewater treatment, agriculture, and aquaculture industries.
