TL;DR: In this article, an electrochemical treatment based on the principle of anodic oxidation was used to treat paper mill effluent from Rakta's Pulp and Paper Company where rice straw is used to produce paper pulp.

TL;DR: An electrochemical mechanism mediated by OCl- operating in the decolorization and COD reduction processes was suggested and oxidized products from the treated effluents were isolated and confirmed to be free from chlorine-substituted products by IR spectroscopy.
Abstract: Removal of color and reduction of chemical oxygen demand (COD) in an industrial azo dye effluent containing chiefly reactive dyes were investigated under single-pass conditions at a dimensionally stable anode (DSA) in a thin electrochemical flow reactor at different current densities, flow rates, and dilutions. With 50% diluted effluent, decolorization was achieved up to 85−99% at 10−40 mA/cm2 at 5 mL/min flow rate and 50−88% at 30−40 mA/cm2 at high (10−15 mL/min) flow rates. The COD reduction was maximum (81%) at 39.9 mA/cm2 or above when solution−electrode contact time (Ct) was as high as 21.7 s/cm2 and decreased as Ct declined at a given current density. Cyclic voltammetric studies suggesting an indirect oxidation of dye molecules over the anode surface were carried out at a glassy carbon electrode. The effect of pH on decolorization and COD reduction was determined. An electrochemical mechanism mediated by OCl- operating in the decolorization and COD reduction processes was suggested. The effluent was...

TL;DR: An increase in influent flux and influent particle concentration corresponds with increasing TMP and filtration resistance, as well as a rapid reduction in effluent turbidity due to swift formation of a DM on the supporting mesh.

TL;DR: A laboratory-scale anaerobic-anoxic-oxic membrane reactor (A(2)O-MBR) system was developed to investigate the treatment ability of coal gasification wastewater and it was found thatAnaerobic process played an important role in degradation of refractory compounds.

TL;DR: The efficiency of a compact Submerged Membrane Bioreactor system to treat real grey water in a single house in Crete, Greece, was examined and average effluent values would satisfy international guidelines for indoor reuse applications such as toilet flushing.
