Emulsified Oily Wastewater Treatment by MHD Water Treatment Device

MHD 수처리방식에 의한 에멀젼오일폐수의 처리

Emulsified oily wastewater is generally hard to treat in separating oil and water by conventional separators. In this paper the magnetohydrodynamic water treatment device was used to separate oil from emulsified oily wastewater which contained high conductivity. The emulsified oil removal rates and economic ranges of oil separation at various factors were investigated to confirm the influence of the magnetic field in MHD water treatment device according to the characteristics of emulsion brake. Experimental results proved that the oil removal rates were proportional to Lorentz force which depends on the intensity of magnetic field, conductivity and velocity of wastewater.
