'Water Pollution in Textile Industry\r'

' step-down In the con. [amount of chemical substances subprogramd thereby reducing their harmful effects. decrease of waste concentration by recuperation and reuse. Reduction of waste concentration by chemical substitution. Reduction of waste concentration by abut modification. Segregation of Fenton of each process. Devising suitable discussion for ultimate government, to meet the requirements. To explore the economics link to reuse of treated Fenton.Reduction In waste piss volume Reducing the number of washing and use of hot water in washings use of look to current washing use of standing lav in tarnishing theatrical role of low booze Ratio systems Good house keeping and taproom of leakages and spillages (A reduction of 20- 40 volume of wastewater generated Is possible) Reduction In con. / amount of chemicals Optimum use is prerequisite, which is not always possible in stuff treat industry Textile processing involves heterogeneous interactions mingled with fiber material †solid and chemicals †liquid, solutions or emulsions.Essential trading operations involved in Textile Processing : utmost penetration of chemicals into fiber material to achieve sought after Interactions. Thorough remotion of unused/unfixed chemicals and Impurities from the fabric material. Because of the heterogeneity of Interaction, only Limited absorption f various types of chemicals and coolants used for chemical processing onto the cloth fiber materials is possible. Reduction of waste con. By convalescence and reuse of Recovery of synthetic sizing agents from desiring clean and their reuse.Reactive discolours have very low BODY) Multifunctional reactive dyes for founder fixation & little unfixed Use of non-ionic go fatty alcohols and anionic polymerases in place of alkyl phenol tessellates CEO-friendly stabilizers, sequestrates Use of mineral acid in desiring Use of enzymes in various processes Substitution of atomic number 11 sulfide for s ulfur dyes Disperse- hydrocarbon carriers No or less kerosene in Pigment Printing fond(p) or complete replacement of printing gums by suitable emulsions Formaldehyde free cationic dye fixing agent, DEEMED, low formaldehyde Low saltiness dyesReduction of waste con. By process modification Use of Foam technology Use of transfer typography printing Combined processes Automatic dispensing Segregation of drainpipe Many a times it is convenient to discriminate 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 utmost necessary to have sufficient concentration of the chemical / dye in the waste water that can be economically recovered and put to reuse. If the concentration is excessively low or if the chemical is cheap, then this proficiency s ineffective.Devising suitable intercession for ultimate garbage disposal Depends on mode of discharge of effluent. Balance amid the capit al cost and running cost of discussion. If disposal is into public sewers, preliminary treatment (screening, grit removal and equalization) followed only by primary treatment with chemical coagulation, flocculation and sedimentation give be necessary. If disposal is straightaway 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.\r\n'
