Mechanism of Pollutants Magnetized Biodegradation in Wastewater by Some Yeasts

Khalid Falih Hassan | Noor Nihad Baqer | Elaaf Safa Al-deen Hassan

Abstract: Magnetic field by 200, 300 and 400 gaos were selective to study their impacts on yeasts Candida dubliniensis, Candida glabrata, Issatchenkia orientalis and Rhodotorula mucilaginosa growth and to reduce organic pollutants in wastewater by COD, TOC, TN and TP in concentrations of 180, 75.52 and 84 ppm in pH 7.6 and treatment periods of 2, 4, 6 and 18 hours in batch system. Results showed that magnetic field 300 gaos have higher ability to increase yeasts growth in 18 hours and reduce COD, TOC, TN and TP by 88, 85, 90 and 98.5 % in same period treatment. While, magnetic field 200 and 400 gaos have no effect on microorganisms growth and reducing organic pollutants.
