abstract background: dyes are visible materials and are considered as one of the hazardous components that make up the industrial waste. dye compounds in natural water, even in very low concentrations, will lead to environmental problems. azo dyes are compounds with one or more –n=n– groups and are used in textile industry. because of its low price, solubility, and stability, azo dyes are widel...

BACKGROUND In the sub-urban areas of Kampala city, springs are a major source of water for domestic use. Though spring water is considered to be aesthetically acceptable for domestic use, presence of poorly designed pit latrines, poor solid waste management as well as poor and inadequate spring protection, may lead to contamination of spring water with pathogenic bacteria. OBJECTIVES The obje...

The physico-chemical properties of tannery and textile effluents and water of adjacent river (Buriganga and Karnatoli, Dhaka) at three different locations were studied. The physico-chemical properties such as Biological OxygenDemand (BOD), salinity, Total Dissolved Solid (TDS), Total Suspended Solid (TSS), Sodium (Na ), Potasium (K ), Calcium (Ca ), Iron (Fe ), Phophate (PO ), Chloride (Cl ), N...

In the world today, the need for sustainable processes is increasing. The work of the present thesis has been focused on conversion of the cellulosic part of waste textiles into biogas and ethanol, and its challenges. In 2009, the global annual fiber consumption exceeded 70 Mt, of which around 40% consisted of cellulosic material. This huge amount of fibers is processed into apparel, home texti...

All-polyamide composite coated-fabric (APCCF) was used as an alternative material for the construction of textile-bioreactors (TBRs), which are prepared as a replacement of the traditional stainless steel bioreactors (SSBRs) or concrete-based bioreactors. The material characteristics, as well as the fermentation process performance of the APCCF-TBR, was compared with a TBR made using the polyvi...

INTRODUCTION Workers in the cotton processing industries risk developing obstructive respiratory conditions due to prolonged exposure to cotton dust. We noted a tenfold increase in asthma among workers in a Textile Manufacturing Company. We determined the prevalence of respiratory obstructive conditions among workers in various sections. METHODS We conducted a cross sectional analytic study. ...

Eco-friendly wet processings of textiles are major concerns of textile producers nowadays to attain high quality products without diversely affecting the environment quality and the enduser health1. Enzymatic processing of textile offers many advantages when compared to traditional chemical methods, namely, enzymes use significantly less water, less energy, and fewer chemicals than traditional ...

This study aimed to identify the metal flow in a municipal solid waste (MSW) management system. Outputs of a resource recovery facility, refuse derived fuel (RDF) production facility, carbonization facility, plastics liquefaction facility, composting facility, and bio-gasification facility were analyzed for metal content and leaching concentration. In terms of metal content, bulky and incombust...

aims: the effect of electrochemical process on polyphosphate alone has not been yet investigated. the aim of this study was to study polyphosphate removal from synthetic wastewater by electrochemical process.  materials & methods: this research was carried out experimentally on 50 samples of synthetic wastewater. in each run 2000ml of sw took place in a batch. a constant 600ma direct current wa...

Textile industry has become an essential part of modern society, and waste production is an inevitable outcome of the developmental activities. Present paper outlines a direct approach toward a real problem of managing spinney waste fibers generated during textile industry. Simultaneously, shortage in landfill disposal space is another trouble associated with dumping of these hazardous wastes. ...
