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.

“…Optimum conditions were obtained for coagulant dosage between 400 mg/L and 450 mg/L. Ghorbani et al (2010) tested the efficiency of sawdust coated with polypyrrole (PPy/SD) and with polyaniline (Pan/SD) as an adsorbent material for pulp and paper effluent treatment. The absorbent materials were prepared using cast method and were effectively used to remove anions, heavy metals, color and COD from effluents.…”

Accelerated population growth combined with the economic growth observed in several countries has greatly contributed to an increased demand for paper. Expansion of paper industry has been the trend in several places in Asia, Central and South America. However, implementation of sustainable practices has not followed the same growth, and the paper industry continues to negatively impact the environment and natural resources. In 2010, pulp and paper effluent management studies focused on the direct and indirect approaches that target the mitigation of these negative impacts. From the large pool of papers, the ones that best represent the 2010 literature on pulp and paper industry effluent management are herein presented. For the purpose of this review, papers have been grouped into the following areas: toxicology and monitoring, sustainability practices, biological treatment, physicochemical treatment, and biochemical treatment. ____________________________________________________

Abstract. Conducting polypyrrole(PPy) was found to possess potential efficiency to remove F − from aqueous solutions. In this study doped with Cl − PPyCl/ATP composites were prepared via in-situ polymerization and employed as adsorbent to remove from aqueous solutions. The ability of the adsorbent to remove F − from aqueous solution was demonstrated in a batch sorption mode.External factors such as initial concentration of F − , contact time, adsorbent dosage and pH value of solution how to influence the adsorption efficiency of composites were investigated. The results showed that the adsorption efficiency is strongly pH, initial concentration and adsorbent dose dependent. Experiment data fitted well to the Langmuir isotherm model. The adsorption kinetics is described by the pseudo-second-order model. Meanwhile, the adsorption may proceed by an ion exchange mechanism between Cl − and F − .
