Removal of chromium(VI) from wastewater by combined electrocoagulation?electroflotation without a filter

Polymer Nanocomposites and Cr(VI) Removal from Water

“…Therefore, it is necessary to remove Cr(VI) from wastewater before it is discharged to the natural water bodies. Various treatment technologies such as ion exchange, electrolytic removal, membrane filtration, reverse osmosis, chemical precipitation, adsorption, and solvent extraction have been reported for the removal of Cr(VI) from waste water [25][26][27][28][29][30][31][32][33][34][35][36][37][38]. Most of these technologies are associated with high operational and maintenance cost.…”

Electrolytic Treatment of Wastewater in the Oil Industry

“…According to [55], the power consumption does not diminish significantly when the conductivity of the solution is greater than 1.5 mS/cm.…”

Effective Photocatalytic Reduction of Cr(VI) by Carbon Modified (CM)-n-TiO2 Nanoparticles under Solar Irradiation

“…In aquatic environments, chromium exists in hexavalent (Cr(VI)) and trivalent (Cr(III)) forms, of which hexavalent form is more toxic than the trivalent one, and is known to be human carcinogen [5]. Different techniques have been reported for the treatments of Cr (VI), such as ion exchange [6], membrane separation [7], physical and biological adsorption [8][9][10], and electrocoagulation [11,12]. However, most of these techniques have several limitations and drawbacks, and they require either high energy or massive use of reducing agents.…”
