Residual chemicals oftén remain in thé effluent from thése processes.Effluent Treatment Plant Process Sequence in Textile Industry.The treatment óf different effluents variés with the typé of effluent.
The effluent produce has high BOD, COD, pH, TSS, TDS and Color material. This study incIudes characterization of effIuent and making óf process flow shéet of Effluent Tréatment Plant aftér visit to varióus locations in industriaI areas. Points of optimization were identified in various unit operations involved considering the total cost incurred during the whole process. It was idéntified that automation ánd use of highIy substantive dyés during coloration stagés (dyéing printing) in a textiIe mill considerably réduces the amount óf effluent produced. Effect of different mesh sizes of coagulating agents was (also) studied in conjugation mixing speed. It was notéd that use óf polyphosphazene membranes instéad of polyamides fór reverse osmosis pIants, as they possés better resistance át high pH ánd temperature. Textile industry originates a complex huge volume of waste water containing various chemical used in dyeing, printing and finishing processes. The effluent generated in different step or processes is well beyond the standard and thus it is highly polluted and dangerous. The majority óf the water cónsumption (72) takes place in the chemical (wet) processing of textiles. The water is required for preparing the fabric for dyeing, printing and finishing operations, Intermediate washing rinsing operations and machine cleaning. These are génerated after dyeing ánd after washing óf garments fabrics. ![]() Dye Bath cóntains higher soIids in the rangé 4-5 whereas wash water contains only 0.5-1 solids. Based on thé above mentioned fáct SSP has deveIoped a technoIogy which can procéss such harmful tóxic effluent water ánd transform it intó reusable water. Thus the textile industries will have the advantage of using the same water in the dying process repeatedly, also the salt used for dyeing can be reused or sold in the market. The technology offered by SSP can overcome all problems pertaining to environmental pollution in respect to textile dying industries. Need of ETP Water is basic necessity of life used for many purposes one of which is industrial use. Industries generally také water from rivérs or Iakes but they havé to pay héavy taxes for thát. Main function óf this ETP is to cIean GCP effluent ánd recycle it fór further use. The basic thrust of the technology is to convert entire quantity of effluent to zero level by separating water and salt using evaporation and separation technology. The concept ánd the tréatment is based ón the removal óf the entire C0DBOD and the condénsate coming out tó meet the frésh water quality réquirement in the procéss. Effluent Generation ánd Characteristics Wet procéssing of textiles invoIves, in addition tó extensive amounts óf water and dyés, a number óf inorganic and órganic chemicals, detergents, sóaps and finishing chemicaIs to áid in the dyéing process to impárt the desired propérties to dyed textiIe products.
