“…From the figure, it is observed that MB elimination at stainless steel electrodes was found to be better as compared to Iron electrodes. The higher efficiency of SS may be because stainless steel promotes a higher potential of direct oxidation of the dye due to its high overpotential of oxygen evolution reaction compared to Iron 15 . Hence, further experiments have been performed by keeping SS as electrodes.…”

“…This technology has many advantages in being attractive for its versatility, ease of control, safety, selectivity, and being able for automation 12 . It involves the insitu generation of the coagulants by the application of direct current voltage to oxidize a sacrificial anode such as Fe 13 , Al 14 , and stainless steel 15 to form flocs.…”

Like other developing countries, Morocco has undergone a real industrial revolution that generates a huge amount of colored wastewater. Methylene blue (MB) could be considered as commonly model of cationic dyes that are widely used in industries. In the present work, the removal of MB was investigated in the presence of NaCl as electrolyte by electrocoagulation (EC) process. Parameters studied are the nature of electrodes, electrode spacing, initial dye concentration, agitation speed, applied current density, NaCl concentration, and the effect of the initial pH. Stainless steel electrodes have been used as cathode and anode in the electrochemical cell. The performance of the process was evaluated in terms of color removal, chemical oxygen demand (COD), total organic carbon (TOC), electrical power consumption, current efficiency, and the quantity of sludge formed. The results showed that the removal percent of 20 mg/L MB is 100 %, using stainless steel electrodes with an interspace of 1.5 cm and 20 mA/cm² for 6 min in the presence of 0.1 M NaCl at natural pH. COD and TOC removals within 15 min were 45% and 51% respectively. The power consumption, in that case, was 5.84 KWh/m3, while the amount of sludge formed was 1.64 Kg/m3.

“…17 Secondary Reactions. Sodium chloride is used as an electrolyte and chloride anions are generated during the EC treatment which oxidizes into Cl 2 (g) by the following reaction: 12 Thus, chlorine, depending on the pH, forms various chlorine species (Cl 2 , HOCl, and ClO − ) in the EC reactor. Hypochlorous acid and hypochlorite are the main chlorine species present in water in the pH range 6−9.…”

The present study investigates the electrochemical (EC) treatment of actual dye bearing effluent (DBE) with different combinations of aluminum (Al) and stainless steel (SS) electrodes as anode and cathode. Effects of the current density (j) and pH with different anode−cathode combinations (Al−Al, Al−SS, SS−SS, and SS−Al) were studied. The change in zeta (ζ) potential with current density at different times, and the change in colloid particle diameters at different pH, gave information regarding the potential stability of the colloidal suspension. In addition, specific energy consumption and current efficiency have also been calculated. Maximum color, COD, TOC, and turbidity removal efficiencies were found to be 99.90%, 82.50%, 68.8%, and 98.8%, respectively, at j = 117.64 A/m 2 and pH 8.5 with the SS−SS electrode combination. Solid residue obtained during EC treatment of DBE was characterized by scanning electron microscopy, energy dispersive X-ray spectroscopy, thermogravimetric analysis, and pore distribution analysis to propose reutilization of the sludge.

ÖZTekstil boyama endüstrisinde kullanılan Bazik Mavi 3 boyarmaddesinin alüminyum elektrot kullanılarak elektrokimyasal olarak tekstil atık sularından giderimi üzerinde çalışılmıştır. Kesikli proses ile yapılan deneyler sonrasında 10 dakika sonunda pH8 değerinde %97'den fazla giderim etkinliği hesaplanmıştır. Elektrokimyasal işlemin 6. dakikası sonunda 50-400 mg/L aralığındaki konsantrasyonlardaki boya giderim etkinliği %92-95 arasında değişirken bu oran, 500 ve 600 mg/L için sırasıyla %72 ve %60 olarak hesaplanmıştır. 10. dakika sonunda ise bütün konsantrasyon değerlerindeki boya giderim oranı %96 civarındadır. Akım yoğunluğu değerlendirildiğinde ise boya giderim etkinliği 333 A/m 2 akım yoğunluğu ile 4. dakikadan sonra (%96) işlem bitene kadar çok fazla bir artış göstermemiş ve 10. dakikada %97 seviyesine ulaşmıştır.Anahtar Kelimeler: elektrokoagülasyon, tekstil atık suları, bazik mavi 3, alüminyum elektrot Removal of C.I. Basic Blue 3 dyestuff from textile waste waters by electrochemical treatment ABSTRACTThe present study investigates the electrochemical treatment of Basic Blue 3 dyestuff from the textile waste waters. We achieved more than 97% color removal with pH8 after 10 minutes. In terms of initial dye concentrations, 92-95%, 72 and 60% dye removal efficiencies were obtained in 6 minutes for 50-400 mg/L, 500 and 600 mg/L initial dye concentrations respectively. In 10 minutes removing efficiencies became 96% for all the concentrations. When we consider the current density parameter, 96% removal efficiency was obtained with 333 A/m 2 current density in 4 minutes respectively. However the removal efficiency only increases to 97% in 10 minutes.
