Electrochemical oxidation and reuse of tannery saline wastewater

Alternative carrier medium for sustainable leather manufacturing – a review and perspective

“…Treatment plants either individually or collectively had been set up to deal with the wastewater management. Advanced treatment systems such as reverse osmosis (Purkait et al, 2009), micro-filtration (Bhattacharya et al, 2013, nano filtration (GalianaAleixandre et al, 2005(GalianaAleixandre et al, , 2011 and electrochemical oxidation (Panizza et al, 2004, Costa et al, 2010and Sundarapandiyan et al, 2010 have been implemented to treat tannery effluents. Such initiatives were only effective in addressing the issue of wastewater management.…”

Application of electrochemical reactor divided by cellulosic membrane for optimized simultaneous removal of phenols, chromium, and ammonia from tannery effluents

“…Under the conditions applied during the experiments, the indirect oxidation was the major route for EOx of the phenolic compounds, as demonstrated by some authors (Costa and Olivi 2009;Samet, Agengui, and Abdelh edi 2010;Santos et al 2010). Experimental conditions probably allowed mediators such as OH Á radicals, Cl 2 , ClO 2 , O 3 , H 2 O 2 , and S 2 O 2 ¡ 8 to generate and contribute to the indirect oxidation (Samet, Agengui, and Abdelh edi 2010;Sundarapandiyan et al 2010). The generation of these inorganic mediators increased with an increase in the current intensity (Mohan, Balasubramanian, and Basha 2007).…”

Performance Improvement of a Sequencing Batch Reactor for Treating Tannery Wastewaters

“…Thus, the conventional biological treatments are frequently inadequate because of the complexity of the chemicals used in the process. This is the reason why alternative or complementary treatments to biological processes, e.g., advanced oxidation processes [1,2] or membrane techniques [3,4], have been reported in the literature.…”
