A Review of the Possibilities for Recycling Aqueous Dyehouse Effluent
نویسنده
چکیده
economic considerations, such as the rising cost of water slipply and effluent treatment, shortage of water created by increased demand, and tighter legal control. Dyehouse effluents contain a wide range of impurities which may be organic or inorganic, soluble, colloidal or suspended. These impurities will limit the suitability of the effluent for immediate recycling to varying degrees depending on their nature and concentration and the class of fibre and W V I F to be subsequently processed. Attention is drawn to die effect of some of the most commonly occum'ng of these impurities on subsequent processing operations. Reference is made to the physical obstacles to recycling issociated with existing machines, drainage systems and factory [ayout. recycling of dyehouse effluents are discussed. These include '

Photocatalytic Treatment of Textile Dyehouse Effluents with Simulated and Natural Solar Light
In the present study, the photocatalytic treatment of two synthetic textile dyehouse effluents was investigated. The first synthetic effluent (SE1) is a Remazol Black B aqueous solution, while the second one (SE2) is an aqueous mixture of sixteen dyes and auxiliary chemicals that are usually employed in the textile industry. Various illumination sources were studied, while emphasis was given on...
متن کاملDecolorization of dyehouse effluent and biodegradation of Congo red by Bacillus thuringiensis RUN1.
A dye-decolorizing bacterium was isolated from a soil sample and identified as Bacillus thuringiensis using 16S rRNA sequencing. The bacterium was able to decolorize three different textile dyes, namely, Reactive blue 13, Reactive red 58, and Reactive yellow 42, and a real dyehouse effluent up to 80-95% within 6 h. Some non-textile industrially important dyes were also decolorized to different ...
متن کاملA survey on the performance of moving bed biofilm reactor and rapid sand filter in wastewater treatment
Moving bed biofilm reactor (MBBR) is a process in which attached growth is utilized for wastewater treatment. This process does not require sludge recycling or backwash. Activated sludge processes can be promoted to an MBBR by adding media to an aeration tank. Rapid sand filter is a physical method for the removal of total suspended solids (TSS) in advanced wastewater treatment. The purpose of ...
متن کاملA review of approaches to direct reverse osmosis membrane recycling: a technical, economic and environmental assessment
Background and Objective: Global market growth of reverse osmosis (RO) has led to an increase in annual disposal of membrane wastes. Therefore, evaluation of membrane waste management strategies is important to reduce their adverse environmental impacts. Due to the widespread domestic RO membrane market and their economic considerations, this study aims at investigation the direct recycling met...
متن کاملAdvanced treatment of textile wastewater for reuse using electrochemical oxidation and membrane filtration
The treatment of textile wastewater for reuse using an electrochemical oxidation step combined with a membrane filtration step is reported in this paper. The electrolytical process is a traditional one, which is easy to scale up and to apply in practice. This paper proposes a modification of the transfer-flow membrane (TFM) module with fibres welded in an arc-shape to enhance the mechanical pro...
