“…Therefore, how to detect and deal with industrial wastewater efficiently and reasonably has become a hot research topic. [5][6][7][8][9] The common wastewater treatment methods include chemical precipitation, redox reactions, biological metabolism and adsorption; [10][11][12][13][14][15] among them, adsorption has become one of the most potential methods for controlling water pollution because of its practicality, convenience, environmental friendliness and many other advantages. [16][17][18][19][20][21][22] As a functional carbon material, expanded graphite has many superiorities such as multiple layers, abundant pore structures and large pore volume and specic surface area.…”

“…The main treatments till now available for the removal of these anthropogenic pollutants and micropollutants involve aerobic biodegradation, filtration, flocculation, adsorption, froth floatation and EC [3]. Some other methods have been applied in combination to overcome the shortcomings of the individual process, including photo-electro-Fenton, electro-Fenton and electro-oxidation [4]. EC is a highly studied process in this field these days.…”

In this research, wastewater treatment was inspected on a pilot-scale wastewater treatment plant by electrochemical techniques, electrocoagulation (EC), electroflotation (EF) and electrophoretic deposition (EPD). The wastewater samples have been characterised by applying different parameters to determine the optimum working conditions of the electrocoagulation reactor. Two electrodes have been tested separately with an outflow coming from the primary and secondary sedimentation tank. The outflows from these tanks are introduced in the EC reactor, and then EC reactor efficacy is determined for the removal of; chemical oxygen demand (COD), suspended solids, micropollutants and amount of coagulants in agglomerates, at different current densities.

Bu çalışmada, kot pantolon üretiminde kimyasal spreyleme işleminden oluşan atıksuyun, Alüminyum (Al) elektrot kullanılarak Elektrokoagülasyon (EK) Prosesi ile arıtımı incelenmiştir. EK prosesi ile KOİ (Kimyasal Oksijen İhtiyacı) ve TÇK (Toplam Çözünmüş Katı) parametrelerinin giderimi için pH, akım yoğunluğu (A.Y.) ve elektroliz süresi (E.S.) gibi EK proses verimliliğinde önemli rol oynayan parametrelerin etkileri belirlenmiştir. Deneysel tasarımda Box-Behnken istatistiksel modeli kullanılmıştır. İstatistiksel analizler her iki kirletici için de sonuçların quadratik modele uygun olduğunu göstermiştir. EK reaktöründe KOİ ve TÇK'nın giderilmesi için regrasyon (R 2) değerinin sırasıyla 0,95 ve 0,99; R 2 adj değerinin sırasıyla 0,88 ve 0,99 olduğu bulunmuştur. R 2 ve R 2 adj değerlerinin 1'e yakın olması, deney sonuçlarının ve istatistiksel çıkarımların uyumlu olduğunu ve işlem parametrelerinin etkilerinin belirlenmesinde Box-Behnken istatistiksel tasarımının etkili olduğunu göstermektedir. KOİ ve TÇK giderimi için optimum pH değerleri sırasıyla 5,01 ve 6,66 olarak tespit edilirken, her iki kirletici için optimum akım yoğunluğu 59 A / m 2 ve elektroliz süresi 29 dk. olarak belirlenmiştir.
