Commercial aviation as has been traditionally known, is undergoing an evolutionary change to new management models. The market, dominated by companies that reduce operating costs and therefore prices offered to customers, is moving towards a new model of airline.

Synthetic dyeing effluents containing a reactive dye (CI Reactive Black 5, Procion Crimson H-EXL, Procion Navy H-EXL, Procion Yellow H-EXL and Procion Blue H-EXL) and Na2SO4 as dyeing electrolyte were studied. Ti/Pt oxides electrodes at different current densities (3, 6,12,24 and 40 mA/cm2) and three UV irradiation lamps (6 and 9W; 254, 360 and 365 nm maximum emission) were used. Results showed that total colour and organic halogenated compounds removal were achieved by UV irradiation after electrochemical treatment. A clear influence of current density and the type of UV lamp on colour removal was found, being the submerged lamps into the dye solution the most efficient.

Electrochemical reduction reactions are mostly used in sulfur and vat dyeing, but in some cases, they are applied to effluents discoloration. However, the main applications of electrochemical treatments in the textile sector are based on oxidation reactions. Most of electrochemical oxidation processes involve indirect reactions which imply the generation of hypochlorite or hydroxyl radical in situ. These electrogenerated species are able to bleach indigo-dyed denim fabrics and to degrade dyes in wastewater in order to achieve the effluent color removal. The aim of this paper is to review the electrochemical techniques applied to textile industry. In particular, they are an efficient method to remove color of textile effluents. The reuse of the discolored effluent is possible, which implies an important saving of salt and water (i.e., by means of the “UVEC Cell”) Wed, 17 Oct 2012 13:22:29 GMT http://hdl.handle.net/2117/16745 2012-10-17T13:22:29Z Sala Gastón, Mireia; Gutiérrez Bouzán, María Carmen no The textile industry uses the electrochemical techniques both in textile processes (such as manufacturing fibers, dyeing processes, and decolorizing fabrics) and in wastewaters treatments (color removal).

These processes are clean, operate at room temperature, and in most cases, do not need the addition of reagents (as in the case of reactive dyeing effluents). In particular, the electrochemical treatment of textile effluents is an efficient method to remove colour. In this work, diverse synthetic effluents containing reactive dyes were treated in an electrochemical cell with Ti/PtO x electrodes. The efficiency of the process to remove colour and the use of an additional UV irradiation were evaluated. Once the conditions were established in synthetic effluents, they were applied on two types of exhausted reactive dye baths collected from a cotton mill. Instead of the effluent discharge, another possibility is to reuse the decoloured effluents for a new dyeing process. In this sense, diverse experiments were carried out and conditions for the effluents reuse were established. The reuse of dyeing effluents implies an important reduction of the salt and water consumption as well as a reduction of the salinity of the discharged effluents.

Its semi-arid climatology is prone to extreme variations depending on the season, chaining long drought periods with heavy rainfalls concentrated in May and October. The lacks in the supply and quality water, especially in rural areas, mean the main cause of illness for intestinal parasites, with especial incidence in the infantile population. The study is located in the rural area of Yako, where one of every three families not has access to potable water sources. It is focused on the purification water treatment by the use of seeds of the plant Moringa Oleifera as natural coagulant to eliminate the turbidity and suspended particles of superficial waters. This treatment is followed by a disinfection process with chlorine produced by electrolysis with a small source of power supply. A sustainable system of water purification is suggested which replaces the use of chemical reagents by natural products, in a energetically self-sufficient process of easy operation. // Burkina Faso (África Occidental) es uno de los países más pobres del planeta.

The most proper dyeing method was established and the influence of alkali was also studied. Wastewater was treated in an electrochemical cell at 20 Lh_1 and 40 mA/cm2 for between 3 and 15 minutes before being reused. During the electrochemical treatment the evolution of the dye degradation was evaluated by COD measurements. From the results, it can be concluded that 70% of the wastewater can be satisfactorily reused by direct bath reuse with most of the reactive dyes obtaining DE (CMC (2:1)) values below 1 with respect to the reference. Differences of DE (CMC (2:1) can be improved up to 75% by applying an electrochemical pre-treatment. In DE (CMC (2:1)) values, DL* was found to be the most influential parameter.

The MBR pilot plant includes an aerobic reactor of 50 l, and membranes of micro and ultra fi ltration, the AS pilot plant has an aerobic reactor of 4 l.

Respirometry was carried out to fi nd the carbonaceous constituents in the wastewater, and also the Ultimate BOD, the mixed liquor suspended solids (MLSS) to evaluate the sludge, and different analysis: chemical oxygen demand and color removal, in order to evaluate process performance. The results show that the range of reduction of COD emissions using the MBR was 89–92%, and using AS was 54–70%, the color removal using MBR was 70% with MF membranes, and 72–73% with UF membranes, and 28% using AS.

The removal of such dyes from wastewater is a problem in textile mills. Electrochemical treatment has proven to be an interesting technique for removing dyes from wastewater, as it does not require any added chemical reagents. Generally, this technique is applied to obtain partial dye degradation (until color removal). In this work, electrochemical treatment was performed in a batch cell. The influence of conductivity, temperature, pH, dye concentration, and dyeing electrolyte on the decoloration was studied. The time required to reach a fixed level of decoloration and the corresponding electricity consumption were also evaluated. Six reactive dyes with different chromophores and reactive groups were selected. The main statistical study was carried out on CI Reactive Orange 13, a textile dye with the commercial name ProcionOrange PX-2R (OrPX). Subsequently, the behavior of the other dyes was studied in comparison with the OrPX models.
