The paper presents our new results about efficiency of wastes based on hydrolyzed polyacrylonitrile textile fibers (HPAN) as sorbents in removal of some dyes from textile effluents. The effect of some experimental variables such as initial dye concentration, sorbent mass, pH, temperature, and contact time were investigated. The sorbent dye sorption systems are described using Freundlich, Langmu...

Industrial wastes may produce leachates that can contaminate the aquatic ecosystem. Toxicity testing in acute and chronic levels is essential to assess environmental risks from the soluble fractions of these wastes, since only chemical analysis may not be adequate to classify the hazard of an industrial waste. In this study, ten samples of solid wastes from textile, metal-mechanic, and pulp and...

potassium ferrate has been used as a multi-purpose chemical in treatment of wastewaters. with the formula of k2fe04 it has 3 excellent characters for water treatment, so by using it alone, it would be possible to confine all reactivity, it is essential to prepare ferrate at the point of use. in this study, k2fe04 was synthesized, then it has been employed for chlorine gas with an alkaline solut...

-------------------------------------------------------ABSTRACT--------------------------------------------------The study attempted an evaluation of environmental and health effect of Nichemtex Industry after ten (10) years a similar study was carried out. Textile industry is composed of a diverse, fragmented group of establishments that produce and or process textile-related products for furt...

This article deals with pollution control through source reduction, as an alternative to waste treatment. Many treatment systems simply remove an undesirable process waste from one medium and capture it in another. For example, scrubbers on smokestacks remove Undesirable combustion products by dissolving them in water. Biodegradation of chemicals in wastewater produces sludges (solid wastes)....

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 textile industry is one of the industries that generate a high volume of waste water. Strong colour of the textile waste water is the most serious problem of the textile waste effluent. The disposal of these wastes into receiving water causes damage to the environment. With regard to their colour removal by conventional treatment methods lead to severe water pollution, thus developing cost ...

Textile dye industry waste is one of the most serious problems in the environment. The dye wastes are severely deleterious to surface water bodies. The present study was an attempt for the assessment of different physicochemical parameters such as pH, temperature, Electrical Conductivity (EC), Total Solids (TS), Total Dissolved Solids (TDS), Total Suspended Solids (TSS), Dissolved Oxygen (DO), ...

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. ...
