The wastewater effluents from textile industries contain highly toxic metal complex dyes. For instance, azo dye has received significant attention owing to its toxicity and environmental stability. This study investigated the oxidation coagulation processes effectively remove effluents. Potassium ferrate (K2FeO4) was selected as an oxidant because it a high potential, is environmentally stable,...

As part of a systematic investigation for a number of Fe(II) porphyrin complexes used as biomimetic models for cytochrome P450, crystals of the title compound, [K(C(18)H(36)N(2)O(6))][Fe(II)(C(64)H(64)N(8)O(4))(HS)], were prepared. The compound exhibits a non-planar conformation with major ruffling and saddling distortions. The average equatorial iron-pyrrole N atom [Fe-N(p) = 2.102 (2) Å] bond...

Iron-manganese co-oxide film (MeOx) has a high removal efficiency for ammonium (NH4+) and manganese (Mn2+) in our previous studies, but it cannot effectively remove CODMn from water. In this study, the catalytic oxidation ability of MeOx was enhanced by dosage with potassium ferrate (K2FeO4) to achieve simultaneous NH4+ water pilot-scale experimental system. By adding 1.0 mg/L K2FeO4 enhance ac...

Biological mechanisms of disinfection not only vary by disinfectant but also remain well understood. We investigated the physiological and transcriptomic response Escherichia coli at late stationary phase to ferrate monochloramine in amended lake water. Although treatments similarly reduced culturable cell concentrations 3-log10, 64% 11% treated cells were viable following treatment, respective...

Excess sludge treatment is indispensable in sewage plants. This study aims to reduce the excess material from activated and establish a mathematical model. Sludge dissolution rates were calculated by measuring total chemical oxygen demand (TCOD) soluble COD (SCOD) with regard water quality before after pretreatment. Then, reduction effects obtained means of suspended solid (SS) changes. The maj...
