Electrofiltration technique for water and wastewater treatment and bio products management: A review
Abstract Application of electric filed in filtration of water and wastewater has been reviewed in present study. Filtration media is one of the basic techniques and is a part of almost all water and wastewater treatment plants used for removal of suspended solids. Application of electrical field across the filtration media upgrades the conventional process for removal of dissolved organic carbon (DOC) in drinking water and wastewater treatment process. Moreover, combination of membrane filtration with electrical field demonstrates improvement in liquid solid separation, permeate flux, quality of filtrate, as well as fouling control/removal. In this work, the removal of various pollutants, such as bioproduct and emerging contaminants, physical and chemical properties of dissolved, collide and suspended particles, and the effects of different parameters, like membrane properties, electrical field and water quality parameters (dissolved organic and inorganic matter, ionic strength, pH) on the efficiency of filtration are reviewed. The industrial viability, future perspective, and advantages of this technology are also investigated.
