Phlebia tremellosa decolourised eight synthetic textile dyes (200 mg l(-1)) by greater than 96% within 14 days under stationary incubation conditions. High performance liquid chromatography analysis of culture supernatants indicated that Remazol Black B was degraded by the fungus, however, complete mineralisation did not occur as a colourless organic breakdown product accumulated. Laccase activ...

This study examined the photolytic degradation of C.I. Acid Red 73 AR73 diazo dye, in aqueous solution by combined UV, hydrogen peroxide and KMnO4. A continuous circulated photoreactor equipped with a low pressure mercury lamp 15 W, emission 253.7 nm was used. In the first step, potassium permanganate was used for decolourisation of AR73 dye solution. The effect of the key operating variables s...

Currently, the textile industry is one of the most important economic sectors in many countries. Besides, it is known as a major consumer of water and consequently one of the largest groups of industries causing intense water pollution. Chemicals, including surfactants, dyes, resins, dispersants agents, inorganic salts, etc., play a variety of functions during the textile processing and are pre...

The fungus Irpex Lacteus is effective in decolourising methylene blue, a common dye printing and dyeing wastewater, it of clear significance to investigate its optimal decolourisation process through liquid fermentation. medium mixed with blue was incubated constant temperature shaking flask fermentation equipment, single factors such as incubation time, temperature, bed speed, concentration, p...

The decolourisation of the reactive Congo red dye from synthetic wastewater was studied using ElectroCoagulation (EC) technique. In an effort to increase removal efficiency, effects operating parameters including flow, inter electrode distance, conductivity, voltage, and Hydraulic Detention Time (HDT) were investigated. An electrochemical cell initially created with aluminum cathode anode. Foll...

In the present study we examined the performance of a thermoalkalophilic bacterial consortium, where the predominant strain was Bacillus sp. SF, in the degradation of Reactive Black 5 (RB5). We used a reactor working in continuous mode and investigated the effects of pH, hydraulic retention time (HRT) and several added salts on colour and chemical oxygen demand (COD) reductions. For the chosen ...

Abstract To solve the problems of unstable chemical oxygen demand (COD), turbidity and suspended solid (SS) removal for electrocatalytic process operation subsequent ultrafiltration membrane–reverse osmosis membrane in a centralised fracturing wastewater treatment plant Inner Mongolia, integrated dissolved ozone flotation (DOF) was proposed to replace original process. Multiple processes, such ...
