Application of Advanced Oxidations Processes for the Treatments of Textile Effluents

Pre-sowing seed magnetic field stimulation: A good option to enhance bitter gourd germination, seedling growth and yield characteristics

“…The mildew that often occurs during germination is responsible for uneven and low germination rates (Peter et al, 1998). Biological and chemical pre-sowing seed treatments have been used for better seed germination and these treatments are considered cost effective and also harmful to the environment (Iqbal et al, 2012a) and the environmental safety is also an important issue worldwide, which already has been contaminated and polluted with toxic agents due to urbanization and industrialization (Abbas et al, 2015;Adesola et al, 2016;Babarinde and Onyiaocha, 2016;Bilal et al, 2014;Iqbal et al, 2013Iqbal, 2016;Iqbal andBhatti, 2014, 2015;Iqbal and Khera, 2015;Iqbal and Nisar, 2015;Jamal et al, 2015;Manzoor et al, 2013;Qureshi et al, 2015;Sayed, 2015;Ukpaka, 2016;Ukpaka et al, 2015;Ullah et al, 2013;Younas et al, 2015). Therefore, it is important to adopt sustainable agricultural practices i.e., environmental friendly, affordable and safe methods Majkowska-Gadomska et al, 2015;Maqsood et al, 2013).…”

Cytotoxicity and mutagenicity evaluation of gamma radiation and hydrogen peroxide treated textile effluents using bioassays

“…Textile industries produce huge volumes of water from wet 7 processing units and resultantly, dyes along with other chemicals 8 are discharged into water sheds. The presence of even very low 9 amount of dyes in the effluent is highly visible and undesirable.…”

“…Many dyes are difficult to decolorize due to their complex 19 structure and synthetic origin. Various methods have been applied 20 for decolorization of textile dyes [3][4][5][6][7] and the conventional 21 treatment systems and biological treatment were found to be 22 inefficient in the removal of these dyes and others environmentally 23 problematic [2,8,9]. Hence, advanced oxidation processes (AOPs) 24 are needed for dyes efficient removal [10,11].…”

“…Hence, advanced oxidation processes (AOPs) 24 are needed for dyes efficient removal [10,11]. In advanced oxidation 25 treatment, strong oxidizing specie like hydroxyl radical ( OH 26 radical) is produced in situ, which break down the complex organic 27 molecule into harmless substances such as CO 2 , H 2 O and inorganic 28 ions through a chain reactions [7,12]. The OH can be generated by 29 radiation alone/ in combination with O 3 , H 2 O 2 /electron beam 30 irradiation/or Fenton's reagent [13].…”

“…The OH can be generated by 29 radiation alone/ in combination with O 3 , H 2 O 2 /electron beam 30 irradiation/or Fenton's reagent [13]. The treatment of wastewater 31 effluents by radiation has advantages such as it degrade non 32 biodegradable organic substances without causing secondary 33 pollution and are considered eco-friendly [7,14]. Q2 34 Bioassays have been used to evaluate toxicity levels of target 35 contaminants and complex aqueous matrices.…”
