The mechanism of Methylene Blue adsorption on acid activated carbon Vitex Negundo Stem (AAVNS) has been studied through batch experiments. Generally, dyes are organic compounds used as coloring products in chemical, textile, paper, printing, leather, plastics and various food industries. The need for the treatment of dye contaminated waste water passed out from the industry. In this study, Vite...

The research of the present work was to investigate the removal of Rhodamine B dyes from aqueous solution by using Activated Acacia Nilotica Shell Carbon (ANSC). Generally, dyes are organic compounds used as colouring products in chemical, textile, paper, printing, leather, plastics and various food industries. The need for the treatment of dye contaminated waste water passed out from the indus...

In this paper, we propose a two-phase approach to solve a combined routing and scheduling problem that occurs in the textile industry: fabrics are dyed by dye-jets and transported by forklifts. The objective is to minimize the cost of the unproductive activities, i.e., the dye-jet setup times and the forklift waiting time. The first phase solves an integer linear program to assign jobs (fabrics...

Bacillus halodurans MTCC 865 was employed for decolorization of textile azo dye, Acid Black-24 (AB-24). Thousand mgl⁻¹ of AB-24 was decolorized with 90% efficiency by the strain within 6 hrs at pH 9 and 37 °C with 5% NaCl under static conditions in screening medium. Decolorization was evaluated by measuring the periodic decrease in absorbance at 557 nm (λ(max)). Biodegradation of Acid Black-24 ...

The reactive dye Cibacron Yellow S-3R was selected to evaluate the feasibility of combining nanofiltration membranes with electrochemical processes to treat textile wastewater. Synthetic dyeing effluents were treated by means of two nanofiltration membranes, Hydracore10 and Hydracore50. Up to 98% of dye removal was achieved. The influence of salt concentration and pH on membrane treatment was s...

A large amount of effluent is generated in textile industries. Dyes used in the dyeing stage of a textile industry is a constant, ardent and keen source of concern to the environmental scientist. This dye effluent cannot be degraded through primary and secondary treatments. Primary treatment involves coagulation and flocculation while secondary treatment encompasses activated sludge process. So...

An activated carbon as adsorbent is derived from waste tendu leaves (Diospyros melanoxylon) from local Beedi (Cigarette) industry for removal of sulphur dye from textile waste water. Tendue leaves were chemically treated with sulphuric acid and activated carbon prepared was analyzed by pH, moisture content, ash content, bulk density and BET surface area. The adsorption studies were performed as...

This paper examines the use of chemical or electrocoagulation treatment process followed by ion-exchange process of the textile dye effluent. The dye effluent was treated using polymeric coagulant (cationic dye-fixing agent) or electrocoagulation (iron and aluminum electrode) process under various conditions such as various current densities and effect of pH. Efficiencies of COD reduction, colo...

The research of the present work was to investigate the removal of Rhodamine-B dye from aqueous solution by using Corchorus Olitorius-L Leaves Nano Carbon (ACONC). Generally, dyes are used in chemical, textile, paper, printing, leather, plastics and various food industries. The need for the treatment of dye contaminated waste water passed out from the industry. In this study, Corchorus Olitoriu...

A variety of adsorbents are available naturallyrice husk, neem bark, clays etc. that can be used to remove dye from the discharged waste. In this study,the use of lowcost, locally available, eco-friendly and highly efficient adsorbent has been investigated as an ideal alternative to the current expensive methods of removing dyes from wastewater. The removal of the textile dye Methylene blue (MB...
