Advanced Oxidation Processes (AOX) are based on the in situ generation of hydroxyradicals (·OH), which have a high oxidation potential. In the case of Fenton processes !he generation of hydroxy radicals takes place by the combination of an oxidation agent (H202) with a catalyst (Fe(II)). These radicals are not selective and they react very fast with the organic matter,being able to oxidize a high variety of organic compounds. This property allows the degradation of pollutants into more biodegradable compounds, and,in some cases, their complete mineralization into C02 and mineral acids. Under optimal conditions, (pH=3, (Fe 2+] = 200 mg/L, [H2O2] = 3612 mg/L) the Fenton processes are able to reduce !he concentration of the organic matter present in the textile effiuent, up lo 97%.

Currently, textile processing plants need to control the conditions associated with the spinning process, being the air conditioning of working environments an important factor in the quality and productivity of these processes. The benefits obtained from the optimization of this air conditioning help to guide a lower energy consumption, helping to improve the positioning of the products and providing profitability in the operation processes. Due to the advantages obtained in the air conditioning process, this work proposes a system that allows reusing the residual energy generated at the outlet of the ventilation ducts. This residual energy is fed into the plant to reduce the high temperatures observed in the ceiling. Consequently, this approach will generate a decrease in the service demand of the air conditioning system and reduce operating costs. Also, to verify this proposal, a mult...

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 a...

A study was proposed in order to standardize the production processes of safety pants and shirts of a company in the city of Pelileo, Ecuador. A mixed approach was employed for the research: a situational analysis of the production process was conducted for the field study, while the product quality was assessed using a sample of 114 internal and external clients. The process was assessed using the 5M criteria (machines, labor, methods, materials and environment). The findings show that production processes did not meet the quality parameters due to a lack in quality control and insufficient infrastructure. 61 % of clients stated that quality control was lacking. 70 % of participants did not approve of the time allotted to each operator for their activities. It was concluded that it is necessary to develop a quality control procedure in order to ensure the quality of the final product.

The response surface methodology was applied to evaluate the optimal experimental conditions to remove persistent organic compounds from a synthetic textile wastewater using a batch photochemical reactor on a laboratory scale. Four factors at three levels were studied: Fenton H2O2/Fe2+ reagent ratio (11,25, 18,75, 26,25 mg/L/mg/L), UV lamp power (4, 11, 18 W), pH (2, 3, 4) and treatment time (60, 120, 180 min). The optimum levels found for the four factors were: ratio of Fenton H2O2/Fe2+ reagents equal to 17 mg/L/mg/L, UV lamp power equal to 4 W, pH equal to 3 and treatment time of 180 min. It was found that the photo- Fenton process is very effective in treating synthetic textile wastewater, with a removal of 86 %, with respect to COD.
