“…The major conflicts associated with textile industries are high water consumption, dye pigments, toxic metals, bases, acids, toxic compounds, and total dissolved solids (TDS) present in wastewater. [1][2][3] The colored textile wastewater not only prohibits photosynthesis activity, it also increases the gene toxicity, carcinogenic, and mutagenic properties of the water, which are major threats to living species or the environment. [4][5][6] Textile dyes have complex structures, synthetic origin, and are non-biodegradable in nature, which makes it necessary to remove them from industrial effluents before being disposed into various hydrological systems.…”

The present study is carried out to evaluate the performance efficiency of biopolymeric and synthetic polymeric coagulants for the removal of color, chemical oxygen demand (COD), and turbidity from textile industrial wastewater. Shells of Gossypium herbaceum (GHC), a bio‐polymeric coagulant from bio‐waste, and polyaniline coagulants (PAC) (a synthetic polymeric) are chosen for the present study. A Box‐Behnken design (BBD) is employed for the optimization of the effects of the four process variables, such as pH, coagulation dose, contact time, and agitation speed, on the removal of color, COD, and turbidity of the wastewater. Fourier‐transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM) are carried out to understand the functional characteristics and surface morphology of the coagulants. The maximum removal of color, COD, and turbidity with GHC is found to be 90.13, 72.96, and 85.48%, respectively, at pH 5.5, coagulant dose 2.2 g L−1, and contact time 35 min, while the maximum removal of color, COD, and turbidity with PAC is found to be 94.38, 91.45, and 89.36%, respectively, at pH 8.0, coagulant dose 1.6 g L−1, and contact time 35 min. The experimental results show that pH and coagulant dose influence the treatment efficiency of GHC and PAC. From the experimental observations, it is concluded that the performance of the biopolymeric coagulant is highly compatible in the treatment of textile industrial wastewater.

“…For pH < 6, reducing the protons to H 2 and producing hydroxide ions in solution caused less COD removal efficiency . Khandegar and Saroh reported that the maximum COD removal efficiency of 84.6 and 76.9% was determined at pH 7.2 for Al‐Al and Fe‐Fe electrodes, respectively . Wang et al also investigated the efficiency of COD removal at different pH values, ranging from 2.5 to 9.5.…”

“…[44] Khandegar and Saroh reported that the maximum COD removal efficiency of 84.6 and 76.9% was determined at pH 7.2 for Al-Al and Fe-Fe electrodes, respectively. [45] Wang et al [46] also investigated the efficiency of COD removal at different pH values, ranging from 2.5 to 9.5. The optimal pH of their study was found to be 5.1 and the COD removal efficiency was about 66% using Al-Al electrodes.…”

This study aims to develop an easy and economic technique for dairy cleaning‐in‐place wastewater treatment to obtain high‐quality treated wastewater effluent. A batch electrocoagulation (EC) study is conducted using iron and aluminum electrodes. The effects of various operational parameters are investigated on the treatment performance. Maximum soluble chemical oxygen demand (COD) removal efficiencies of 81% for an Fe–Fe electrode and 53% for an Al–Al electrode are obtained at an applied voltage of 10 V, an electrode spacing of 2 cm, pH of 7.2, for a reaction time of 60 min. Moreover, protein removal efficiencies of 72.6 and 79.4% are obtained for Fe–Fe and Al–Al electrodes, respectively. An immersed membrane is integrated into the EC reactor and the reactor is operated in continuous mode. COD removal efficiency is determined as 86.4 and 84.5% for Fe–Fe and Al–Al electrodes, respectively, in continuous mode. The protein removal efficiency is also calculated as 80.9 and 83.8% for Fe–Fe and Al–Al electrodes, respectively. The Fe–Fe electrode shows the maximum COD removal efficiency, whereas Al–Al provides the maximum protein removal efficiency. Additionally, field emission scanning electron microscopy (FE‐SEM) and Fourier transform IR spectroscopy (FT‐IR) are applied to describe fouling phenomena.

“…[8].They used hybrid material composed of waste tyre rubber and zeolite.They observed that increase in the hydraulic retention time(HRT) brought about an improvement in the effluent quality.Kulkarni and Goswami used bagasse flyash as an adsorbent for organic matter removal from wastewater [9]. They carried out investigation in batch and column modes with satisfactory results.Electrocoagulation was used for organic matter removal by Khandegar and Saroh [10].They obtained COD removal efficiency was 84.6 % and 76.9 % at initial pH (7.2).Many investigations have been varried out for COD removal by using various advanced biological treatment [11][12][13][14]. These treatment includes both, aerobic and anaerobic methods.…”
