1. Effects of direct and alternating current on the treatment of oily water in an electroflocculation process
In the direct current mode (DC), widely used in electroflocculation (EC), the formation of an impermeable oxide layer on the cathode causes the declining of the efficiency of this process. This disadvantage has been reduced by adopting alternating current (AC). In this study, the effects of AC and DC on operational parameters such as the removal of oils and

2. Avaliação do processo eletrolítico em corrente alternada no tratamento de água de produção
The main objective was to study the treatment of wastewater generated by the oil industry. This work consisted of tests of electroflocculation with alternate current (AC), and chemical coagulation. The removal efficiencies of organic load were evaluated by the removal of oils and greases, color and turbidity. The parameters investigated were the change in al

3. Tratamento de resíduos de corante por eletrofloculação: um experimento para cursos de graduação em química
This paper describes the use of a simple experiment of electroflocculation for classroom in Chemistry. Parameters such as electrode material, current density and temperature direct influence the process efficiency. Due to the process low cost and efficient color removal, the methodology proposed has shown good potential for use in wastewater treatment. In ad

5. Electroflocculation for textile wastewater treatment
This work reports on the viability of the electroflocculation (EF) process for chemical oxygen demand (COD), turbidity and color removal from a raw effluent originated from a particular textile industry related to hemp manufacture. Firstly, the following operational parameters were optimized: current density; initial pH; electrolysis time; material of the el

6. Application of electroflocculation technique for the tannery effluent treatment / AplicaÃÃo da tÃcnica de eletro-floculaÃÃo no tratamento de efluentes de curtume
In the present work has been studied the electro-flocculation efficiency on the reduction of organic and inorganic material concentrations such as Chemical Oxygen Demand (COD), turbidity, total solids and metal, mainly chromium, on an untreated tannery effluent using a pair of electrodes. For this purpose, a lab scale Electro-Flocculation (EF) reactor was co

7. Aplicação da tecnologia de eletrofloculação na recuperação do corante índigo blue a partir de efluentes industriais
The indigo blue dye is widely used in the textile industry. When discarded, besides polluting the environment, it affects the appearance and transparency of aquatic bodies, causing damage to flora and fauna. The removal of this dye from industrial effluents is difficult due to its resistance towards degradation. This work proposes the recovery of indigo blue
