Treatability of water-based paint wastewater with Fenton process in different reactor types

Fenton´s Process for the Treatment of Mixed Waste Chemicals

“…Among AOPs, Fenton's reagent has been used (either alone or in combination with other treatments) as a chemical process for the treatment of a wide range of wastewaters. Recent applications of Fenton´s reagent include the pre-treatment of olive mill wastewater (Lucas & Peres, 2009), the treatment of landfill leachate (Deng & Englehardt, 2006;Zhang et al, 2005), copper mine wastewater (Mahiroglu et al, 2009), water-based printing ink wastewater (Ma & Xia, 2009) and cosmetic wastewaters (Bautista et al, 2007), the degradation of pesticide (Li et al, 2009;Chen et al, 2007), antibiotic (Ay & Kargi, 2010;Elmolla & Chaudhuri, 2009), high-strength livestock wastewater (Lee & Shoda, 2008) and organic compounds of nuclear laundry water (Vilve et al, 2009), the oxidation of combined industrial and domestic wastewater (Badawy & Ali, 2006), the pre-oxidation of pharmaceutical wastewaters (Martínez et al, 2003), the treatment of water-based paint wastewater (Kurt et al, 2006) and cellulose bleaching effluents (Torrades et al, 2003), the degradation of the explosives 2,4,6-trinitrotoluene (TNT) and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) after iron pretreatment (Oh et al, 2003), and the treatment of different streams of textile wastewaters, such as the treatment of hot desizing wastewaters (Lin & Lo, 1997), and the treatment of dye wastewaters (Wang et al, 2008;Gulkaya et al, 2006). Fenton´s reagent is also combined with biological process, as a pre-treatment to enhance the biodegradability of the recalcitrant compounds and lower the toxicity (Padoley et al, 2011, Mandal et al, 2010, Badawy et al, 2009 or as a post-treatment to improve the efficiency of the wastewater treatment (Ben et al, 2009, Yetilmezsoy & Sakar, 2008).…”

Improvement of COD and color removal from UASB treated poultry manure wastewater using Fenton's oxidation

“…Because Fenton's oxidation process yields satisfactory final effluents, in recent years this technology has been applied to many environmental problems such as further treatment of organics in anaerobically treated leachate by Fenton coagulation [11], advanced treatment of opium alkaloid industry effluents using Fenton's oxidation [9], treatment of methyl tertiary-butyl ether (MTBE) contaminated wastewaters using Fenton's reagent [10], oxidation of aromatic groundwater contaminants [12], treatment of water-based paint wastewater with Fenton process [13], advanced oxidation of olive-oil mills wastewater [14], and removal of atrazine by step-wise Fenton's processes [15].…”

Su Bazlı Boya Atık Suyu Arıtımında Bir Adım İleri Gelişmiş Deneysel pH Kontrol Uygulaması

“…Zehirli yapısı ve bileşenlerinin kararlılığı nedeniyle alıcı ortamlara deşarj edilmesi tehdit oluşturan atık suların önce kirlilik yükünü azaltmak ve askıda katıları, metal iyonlarını ve mikroorganizmaları uzaklaştırmak için etkili ve ekonomik bir arıtım yapılması gerekmektedir [4,5]. Su bazlı boya endüstrisi atık sularının arıtımında mikrofiltrasyon, adsorpsiyon, biyolojik arıtım, Fenton, elektrooksidasyon, elektrokoagülasyon, membran ve koagülasyon-flokülasyon gibi çeşitli yöntemler kullanılmaktadır [2,[5][6][7][8][9][10][11][12]. Bu yöntemlerden koagülasyon-flokülasyon atık su arıtımında yüksek giderim verimleri elde edilmesi bakımından dikkat çekmektedir.…”
