“…The scarification of the electrode plates leads to an increased metal concentration in the solution which may in turn precipitate as oxide precipitates [45]. The same phenomenon is described by [46], where the increase in turbidity is due to the iron monomeric species formed during electrocoagulation, the ion Fe 3+ facilitates a yellow coloration and also exists in fine particles in the Fe(OH) 3 species, which is also characterized by its difficulty to dissolve. The observed increase in turbidity, COD, and TSS under Fe-Fe electrode combination from defeathering wastewater can be linked to the -color formation [47].…”

Understanding the efficiency of different wastewater treatment technologies tested under real conditions is essential for successful decision making by engineers and managers. In this study, real poultry slaughterhouse wastewater coming from defeathering, cooling, and evisceration processes was treated using a lab-scale electrochemical process by use of iron-iron (Fe-Fe), iron-graphite (Fe-Gr) and aluminum-graphite (Al-Gr) electrode combinations. A water quality index (WQI) was developed and used as a tool for evaluating and classifying the effectiveness of different electrode combinations. The Al-Gr electrode combination showed an impressive performance achieving an “excellent” status for all of the three studied sources of wastewater with a WQI ranging from 13 to 34. The Fe-Gr electrode combination showed an “excellent” status performance for the wastewater from the cooling process as classified by the WQI and “good water” class for the defeathering and evisceration processes. The lower performance, which was highly affected by the increase in turbidity, was observed for the Fe-Fe electrode combination with a “poor water” status for the wastewater coming from defeathering and cooling processes and “good water” status for evisceration process.

“…Synthetic samples of the textile dye acid black 194 (AB194, CI 22910) were treated by this method using iron anodes at two different initial pH values The elimination of the dye using iron electrodes was effective by applying high current densities (5.0 and 10.0 mA cm -2 ), reaching a total discolorization in less than 60 minutes and a total organic carbon decay over 75%. It was established that the best experimental conditions of pH and current density are 8.5 and 5 mA cm -2 , respectively [11].…”

Dyes have been used in several industries, like paper-making, textiles, plastic, leather tanning, cosmetic and foods industries since Eighteenth century. Effluents containing dyes reduce the penetration of sunlight into natural bodies of water, thus leading to a decrease of both photosynthetic activity and the concentration of dissolved oxygen. The presence of dyes in watercourses is both aesthetically unacceptable and also toxic to aquatic ecosystem and human health. The effluent treatment technologies being used now a days for removal of dyes from wastewater includes coagulation, biological methods, adsorption, advanced oxidation processes, membrane technology, electrochemical methods, nano technology etc. In this review, extensive information is presented with regard to different techniques adopted for dyes removal from the available literature.

The wastewater treatment becomes more necessity. A cheap and more effectively methods for treating liquid waste before discharging it into any other water systems is required. A lot of wastewater technologies are known which include physicochemical treatment processes and biological treatment processes .This technique depend on electrochemical technology which being improved and developed to minimize the addition of chemicals. This study was aiming to investigate the efficiency of the electro-coagulation technique for removal of COD, BOD, Oil and Grease and TSS from Industrial Wastewater from Meat and Slaughterhouse industry in Tanta, Gharbeya, Egypt. Electro-coagulation is depend on passing of an electrical current (DC current) through a liquid, using an anode electrode and cathode electrode. In present study mixed electrodes of iron and aluminum are used and under the optimum condition of current density = 20 mA/cm2, distance between electrodes = 5 cm and retention time = 40 min. It maximum removals efficiency of COD, BOD, TSS, and oil & grease were 96.6%, 96%, 94.5%, 98.1% respectively.
