“…In recent years, the combined processes, in particular physicochemical and biological combined treatments, have received a growing attention for their efficiency to achieve complete mineralization of biorecalcitrant compounds with the objective to reduce operating costs [1][2][3][4][5][6][7][8][9][10][11][12]. In such systems, a physicochemical pretreatment such as an advanced oxidation process (AOP) or an electrochemical method is used to change the structure of pollutants.…”

“…The aim is to obtain less toxic and more biodegradable intermediates, giving rise to a complete mineralization after a subsequent biological treatment. A lot of studies have highlighted the possibility to use combined processes for the removal of non-biodegradable pollutants such as pesticides [1, 4-6, 9, 11, 13-15], dyes [7,10] and pharmaceuticals [3,8,12,[16][17][18][19].…”

“…For physicochemical study, they used ferrous sulphate, ferric chloride and alum as coagulants and for biological treatment activated sludge process was used in an oxidation ditch. Sirtori et al (2009) reported that pharmaceutical industrial wastewater contained nalidixic acid (an antibiotic pertaining to the quinolone group), which cannot be easily biodegraded. The biodegradability of nalidixic acid was achieved by the chemical oxidation process followed by biological treatment.…”

During the past few decades, pharmaceutical industries have registered a quantum jump contributing to high economic growth, but simultaneously it has also given rise to severe environmental pollution. Untreated or allegedly treated pharmaceutical industrial wastewater (PIWW) creates a need for time to time assessment and characterization of discharged wastewater as per the standards provided by the regulatory authorities. To control environmental pollution, pharmaceutical industries use different treatment plans to treat and reuse wastewater. The characterization of PIWW using advanced and coupled techniques has progressed to a much advanced level, but in view of new developments in drug manufacture for emerging diseases and the complexities associated with them, better sophisticated instrumentation and methods of treatment are warranted. The bioremediation process to treat PIWW has undergone more intense investigation in recent decade. This results in the complete mineralization of pharmaceutical industries' wastewater and no waste product is obtained. Moreover, high efficiency and low operation cost prove it to be an effective tool for the treatment of PIWW. The present review focuses on the characterization as well as bioremediation aspects of PIWW.

“…Municipal and industrial wastewaters are often polluted by various synthetic organic compounds such as surfactants, dyes, pharmaceuticals and other industrial chemicals and by-products (Li et al 2012a;Sirtori et al 2009;Li et al 2012b;Gupta et al 2013;Saleh et al 2014;Mahmoodian et al 2015;Ali and Gupta 2006;Ali 2010;Ali 2012;Ali et al 2012;Ali 2014). Many of these compounds are characterized as recalcitrant pollutants that resist the conventional biological treatment systems.…”

Evaluation of the photocatalytic activities of TiO 2 nanomaterials based on the chemical oxygen demand (COD) analyses under identical experimental conditions was not previously reported. In this work, COD has been selected as an adequate industrial water quality measure toward the establishment of a representative standard test method. The initial COD values of six organic pollutants representing dye, surfactants, phenols and alcohol were set at 30 ± 2 mg/L. Ten of different commercial and synthesized TiO 2 samples representing anatase, rutile and mixed phases were used and characterized. The data of photocatalytic processes were compared to that obtained using the commonly widespread Degussa-P25 TiO 2 (TD). The COD of all pollutants was completely removed by TD at UV exposure dose B9.36 mWh/cm 2 . Consequently, the maximum irradiation dose was set at this value in all experiments. The percentages of COD removal as well as the values of the accumulated UV doses required for complete removal of pollutants were measured using the different TiO 2 samples. TiO 2 samples show different performance abilities toward the various pollutants compared to TD. Based on the obtained data, TiO 2 photocatalysts were divided into two categories according to the hydroxyl radical formation rates. Comparison with previous studies reveals that the photocatalytic efficiency evaluation depends on the method of measurement. COD is recommended to be used as an adequate technique of analysis that meets the purpose of water treatment applications.
