Detoxification and discoloration of Moroccan olive mill wastewater by electrocoagulation

Electrocoagulation in Wastewater Treatment

“…This was achieved using red dye from Moroccan textile using a 20 L external loop air-reactor with a batch electrocoagulator [48]. [49] . Balla et al studied the efficiency of an electrocoagulation/electroflotation had a 90% removal rate of color with synthetic mixture as compared to 78-90% removal of color in textile wastewater by providing mixture of Red S3B 195, Yellow SPD, Blue BRFS, Yellow Terasil 4G, Red terasil 343, and Blue terasil 3R02.…”

Electrohydrolysis of Olive Mill Wastewater: Effect of Applied DC Voltage

“…Besides these methods; advanced treatment processes such as ozonation [7]- [8]- [9], photocatalysis [10], electrocoagulation [5]- [11], fenton oxidation [12], ozone and fenton oxidation [13] and wet air oxidation [14] have been tested for olive mill wastewater treatment. However, these processes have a disadvantage of either high operating costs or high sludge quantities which requires additional treatment thereby additional investment and operating cost.…”

Statistical Approach To Reduce Pollution Load From Paper Mill Effluent By Using Coagulation & Adsorption Methods

“…The dark color in paper mill effluent is caused due to the presence of organic ligands such as wood extractives, resins, synthetic dyes, tannins, lignin and its degradation products. The wastewater has to meet the national standards of discharge limits before disposal onto land or water bodies [5][6][7][8][9]. Several physico-chemical and biological treatment methods employing a variety of chemicals and microorganisms have been proposed in the past to remove COD, BOD and color from wastewater and the drawbacks of these methods have been reported [10,11].…”
