Abstract
Membrane fouling is a serious problem facing the performance of water desalination systems. one of the most reason causing this fouling is water hardness as a CaCO3 due to the inorganic pollutants Ca+2 and Mg+2 in feeding water. This problem is the main object studied by this research by using the magnetic field applying various magnetic strong (1000-3000,6000) Gause, to study the effect of magnetic field on reducing the membrane fouling through reducing the water hardness. Results showed that at high magnetic strong led to increasing water hardness removal, that’s mean low fouling materials on the membrane. It was found that magnetic treatment reduce the water hardness to about 55-60% when 3000-6000 Gause, magnetic field was applied and at level of water flow rate (7.0 l/min). The microstructure test showed that a fouling trace found on the membrane using in the control treatment unite compare with the filter membrane which applied the magnetic treatment technique. Reducing membrane fouling rate enhancing water desalination unite efficiency and the membrane operating time.
