Very Adverse Textile Waste Pollution

Textile waste containing hazardous materials. When reviewed in the chemical, the waste consists of organic and inorganic chemicals. Most of the textile wastewater containing inorganic chemicals. Chemicals used in textile manufacturing process is a starch, gelatin glue, resin, Polyvinyl Alcohol (PVA) and carboxymethyl cellulose (CMC).

Textile waste production source, which is when the process of eliminating starch. Solvent removal is usually discarded and the kanji contain chemicals starching and relievers starch, PVA, CMC, enzymes, acids. Removal of starch base gives BOD compared with most other processes. Meriseration cooking and bleaching of cotton and all fabric is an important source of liquid waste, which produce acids, alkalis, COD, BOD, suspended solids and chemicals. These processes generate large volumes of liquid waste.

Signs of textile waste pollution. Usually textile waste water that has not been processed and has a pH outside the neutral pH, will change the pH of river water and can interfere with living organisms in there. Wastes with a pH of acid / low is corrosive to metal. Change the color, smell and taste is one of the signs that water has been polluted. The textile waste in the form of solid, if not dissolve completely will settle in the riverbed.
