Membrane bioreactor (MBR) and reverse osmosis (RO) membrane system was applied to the treatment and reclamation of textile wastewater in Thailand. An experiment was carried out to determine the fouling behavior and effect of anti-scalant and biocide addition to flux decline and its recovery through chemical cleaning. The RO unit was operated for one month after which the fouled membranes were c...

groundwater is the most widely distributed resource of the earth and groundwater quality evolves rapidly as it passes through the subsurface pathways within the unsaturated zone. increasing urbanization and anthropogenic activities have added to the problem of deficient amount of good quality groundwater. the study area is an industrial hub for textile sector. textile production, particularly d...

water plays a vital and essential role in our ecosystem. this natural resource is becoming scarce, making its availability a major social and economic concern. use of a large variety of synthetic dyes in textile industries has raised an hazardous environmental alert. about 17 - 20% of freshwater pollution is caused by textile effluents. these effluents are recalcitrant to biodegradation and cau...

As a natural protein, silk has a tremendous demand as textile commodity. However, compared to Bombyx mori silk, commonly known as mulberry silk, the other non-mulberry silks have some drawbacks like coarseness, low draping, wash and wear characteristics etc. which can be changed using chemical treatment. In this study, effects of some highly polar, non-polar and bipolar solvents on fibre of mug...

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...

background : textile wastewater is the most important pollutant of the environment. navy blue (nb) ce-rn is an important chemical dye widely used in the textile industry. the present study aimed to investigate the removal of nb textile dyes from aqueous solutions using magnetic iron oxide absorbents. methods: in this study, a sample of synthetic wastewater with nb concentration of 50 mg/l was u...

Since discharge limits are becoming stricter for industrial wastes, textile manufacturers are searching for 3fficient and economical methods of pollution reduction. This is typical of :he situation facing the textile ndustry, especially in the area of :olor pollution emitted into the zarth's waterways. Ozone treatment ;o remove color from wastewater :ould be a solution to the problem of

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...

Textile industry is one of the most important and rapidly developing industrial sectors. It has a high importance in terms of its environmental impact, as it consumed high amount of processed water and produce highly polluted discharge water in large amount. Dying and printing mills comprises various operations include desizing, scouring, washing, finishing etc so they produces large amount of ...
