in this survey, with the main objective of studying final effluent treat ability of pars paper industries, the quantitative and qualitative characteristics of the effluent were firstly determined, which showed a min. and max. rate of 1350 and 1800 m3/hr, with 1400 mg/l and 839.5 mg/l respectively for cod and tss, as the main contaminants. also cod and tss population equivalents were calculated ...
Textile effluents are among the most difficult-to-treat wastewaters, due to their considerable amount of recalcitrant and toxic substances. Fungal biosorption is viewed as a valuable additional treatment for removing pollutants from textile wastewaters. In this study the efficiency of Cunninghamella elegans biomass in terms of contaminants, COD and toxicity reduction was tested against textile ...
An overview of the important aspects of managing and controlling industrial effluent discharges to public sewers namely sampling, characterization, quantification and legislative controls has been presented. The findings have been validated by means of a case study covering three industrial sectors namely, tanning, textile finishing and food processing industries. Industrial effluents discharge...
In Rajasthan 21,000 workers are engaged in hand processing textile industries (process gray/raw cotton cloth). They are exposed to hazards of the textile industries besides the harsh conditions of the desert which contributes to adverse effects on their health. To explore the occupational health problems of the desert textile workers and their association with nutrition and environmental factor...
Textile industry comprises of dry mechanical and wet chemical processing,wet chemical process comprises of bleaches, dyeing , printing, & finishing. Dyeing is art of colouration to textiles.Dye get transferred to textile during dyeing. Dyeing operation is performed by the reaction between fiber and dyes. Some dyes are water soluble and some are water insoluble. Some fiber has affinity to dye; s...
Cotton fibre is mainly composed of cellulose, although non-cellulosic polysaccharides play key roles during fibre development and are still present in the harvested fibre. This study aimed at determining the fate of non-cellulosic polysaccharides during cotton textile processing. We analyzed non-cellulosic cotton fibre polysaccharides during different steps of cotton textile processing using GC...
Textile wastewater is difficult to treat as it usually contains considerable amounts of different pollutants, which are often recalcitrant, toxic and inhibitory. Therefore, complex treatment schemes based on the sequence of various steps are usually required for an effective treatment. This explains why textile effluents are often treated in centralized plants and sometimes mixed with municipal...
The spread of HIV and hepatitis viruses by contact of contaminated materials has created increased pressure for protection of personnel with functional clothing; also, all articles of apparel and home textiles are susceptible to problems of hygiene in normal daily use, for example, socks, sport wear and working clothes as well as mattresses, floor coverings, and shoe linings. Textiles for outdo...
Bacillus subtilis C3, a commercial textile dye-decolorizing and -degrading bacterium, was isolated from the common effluent treatment plant (CEPT) of the Jetpur textile dyeing and printing industrial sector situated in the district of Rajkot, Gujarat, India. Here, we present the annotated 4.18-Mb draft genome sequence of B. subtilis C3, providing information about the metabolic pathways involve...
