Water Pollution in Textile Industry

Reduction In the con. amount of chemical substances used thereby reducing their harmful effects. Reduction of extravagance preoccupancy by recovery and reuse. Reduction of waste concentration by chemical substitution. Reduction of waste concentration by assist modification. Segregation of Fenton of each process. Devising suitable interference for ultimate disposal, to meet the requirements. To explore the political economy related to reuse of treated Fenton.Reduction In waste water loudness Reducing the number of washing and use of hot water in washings use of counter current washing use of standing lavatory in dyeing drug abuse of low Liquor Ratio systems veracious house keeping and prevention of leakages and spillages (A reduction of 20- 40 volume of effluent generated Is possible) Reduction In con. / amount of chemicals Optimum use is necessary, which is not unendingly possible in textile touch on industry Textile processing involves heterogeneous interactions between c ase material solid and chemicals liquid, solutions or emulsions.Essential operations involved in Textile Processing Maximum penetration of chemicals into fiber material to achieve desired Interactions. Thorough removal of unused/ floating(prenominal) chemicals and Impurities from the textile material. Because of the heterogeneity of Interaction, all Limited absorption f unhomogeneous types of chemicals and coolants used for chemical processing onto the textile fiber materials is possible. Reduction of waste con. By recovery and reuse of Recovery of synthetic sizing agents from desiring toilet and their reuse.Reactive dyes have very low BODY) Multifunctional reactive dyes for better fixation & slight unfixed Use of non-ionic tessellate fatty alcohols and anionic polymerases in plaza of alkyl phenol tessellates CEO-friendly stabilizers, sequestrates Use of mineral acid in desiring Use of enzymes in various processes Substitution of sodium sulfide for sulfur dyes Disperse- hydr ocarbon carriers No or less kerosene in Pigment Printing partial(p) or complete replacement of printing gums by suitable emulsions methanal free cationic dye fixing agent, DEEMED, low formaldehyde rugged salt dyesReduction of waste con. By process modification Use of foam technology Use of transfer paper printing Combined processes robotlike dispensing Segregation of drain Many a times it is convenient to single out the waste water of a particular textile wet process for efficient reuse/ recovery of chemicals or dyes. This leads to economy of the process. However it is extent necessary to have sufficient concentration of the chemical / dye in the waste water that can be economically recovered and contrive to reuse. If the concentration is too low or if the chemical is cheap, then this technique s ineffective.Devising suitable handling for ultimate disposal Depends on modal value of discharge of effluent. Balance between the capital follow and running cost of treatment. If di sposal is into public sewers, preliminary treatment (screening, grit removal and equalization) followed only by primary treatment with chemical coagulation, flocculation and sedimentation will be necessary. If disposal is directly to stream then primary and secondary treatment is necessary. If disposal is on the agriculture land, primary treatment followed by gypsum treatment for reduction of sodium will be necessary.
