Abstract

Textile effluents from Franky & Ricky S.A (Arequipa-Peru) were treated using coagulationflocculation process by the two commercial agents Perifloc and Al2 (SO4)3, and Triticum aestivum L. starch as an aid of the process. The treatment capacity was determined by the degree of removal of Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD5), Total Suspended Solids (TSS), pH, and light absorbance (Coloration level). Due to the variance of textile effluent COD, BOD, TSS and coloration, two different optimal doses were established for effluents with high and low coloration of dyes, being 18 and 12 mg·L-1 for Perifloc, and 150 and 50 mg·L-1 for Al2(SO4)3 respectively. The use of T. aestivum starch showed good ability to support textile treatment process effluents when applied to half of the optimal dose of Perifloc at 0.5 g · L-1 for the case of effluents with high loading dye and 0.05 g · L -1 for low load, achieving good characteristics treated effluent for discharge to sewer systems according to the MPVs; however, good results were not achieved in its implementation over half of the optimal dose of the agent Al2(SO3)4, being positive for treating effluents with low load dye effects, only achieving a minimum level of aid applied 0, 05 g · L-1 starch about half the optimal dose (150 mg · L-1) corresponding to the treatment of effluents with high load textile dye.
