Global warming is one of the most important issue addressed these days, the increase in the pollution is the main of reasons that is causing global warming.
Effluent pollution that is the type of water pollution that mainly is discharged from industries is one of the reasons of this pollution that is directly related to the global warming. Pakistan plays a vital role in the textile sector, the most used material is cotton.
“The textile dyeing industry is well-known for being a major polluter of the environment” (Christie, 2007): This is primarily due to high effluent discharges of inorganic salts, alkalis, other processing aids like surfactants, and organic matter like dyes. Effluents from reactive dyeing cotton are particularly polluted, with high oxygen demand, color, and salt load. The industry also consumes a significant amount of clean water. Effluent treatment and water recycling can help to reduce discharge pollution and provide reusable processing water.
The obvious better approach would be to modify textile processing technologies and chemistry to reduce effluent pollution. Such a proactive approach to environmental protection has grown in importance around the world. There are some techniques that textile sector should adopt in order to save our planet. Like, the use of non-toxic biodegradable dyes and chemicals for dyeing is a direct approach to reducing effluent pollution. The use of specific organic compounds has been shown to be a viable alternative to inorganic salt. Because most of these compounds are biodegradable, they reduce effluent load.
Cotton cationisation has been shown in reactive dyeing to be capable of eliminating the use of inorganic salt and alkali while leaving a reduced amount of unfixed dye. This has significant environmental advantages. Biological treatment is typically considered to be the most efficient method for removing the majority of toxic pollutants from complex organic effluent. The biodegradation of synthetic dyes and other dissolved substances is typically accomplished by natural or regenerated bacteria in these processes.
To conclude biological treatment is typically considered to be the most efficient method for removing the majority of toxic pollutants from complex organic effluent. The biodegradation of synthetic dyes and other dissolved substances is typically accomplished by natural or regenerated bacteria in these processes.
