“…Textile industry consumes over 7000 different compounds including dyes, surface active agents, and electrolytes (Hessel et al 2007). It was reported that due to inefficiencies of the industrial dyeing operations, 280,000 tons of various dyes per year worldwide are discharged in wastewaters (Jin et al 2007).…”

“…It was reported that due to inefficiencies of the industrial dyeing operations, 280,000 tons of various dyes per year worldwide are discharged in wastewaters (Jin et al 2007). From 10 to 20% of acid dyes in a non-fixed form can be released to textile effluents (Hessel et al 2007). Azo dyes are degraded under anaerobic conditions to toxic aromatic amines in the receiving medium (Robinson et al 2001).…”

Nanosized silica–titanium oxide as a potential adsorbent for C.I. Acid Yellow 219 dye removal from textile baths and wastewaters

The mixed SiO 2 -TiO 2 oxide obtained by the pyrogenic method with the silica:titanium percentage ratio equal to 80:20 (ST20) was used as a potential adsorbent for the removal of hazardous azo dye C.I. Acid Yellow 219 (AY219) from aqueous solutions. Based on the values of determination coefficients (r 2 ), it can be stated that the Freundlich (r 2 = 0.929) model fitted the experimental data better than the Langmuir (r 2 = 0.920) and Tempkin (r 2 = 0.848) ones. In the system containing 20 mg/L AY219, the amount of dye adsorbed (q t ) by ST20 was equal to 9.7 mg/g and the time necessary to reach equilibrium was 120 min. The sorption of AY219 on ST20 may be described by the pseudo-second-order model (r 2 = 0.999) as the adsorption capacity was calculated as 9.69 mg/g. The amount of AY219 adsorbed decreased with the increasing concentration of additives such as anionic and non-ionic (Triton X-100) surfactants. In the presence of cationic surfactant, the reverse dependence was observed. Anionic dye additions influence the structure of electrical double layer formed on the surface of mixed oxide particles. The presence of negative charges in adsorbed AY219 molecules results in increase of the solid surface charge density with simultaneous decrease of the zeta potential of ST20 particles. The addition of surfactants with different ionic character causes formation of complexes whose presence at the mixed oxide-liquid interface influences considerably both the solid surface charge density and the zeta potential of ST20 particles dispersed in aqueous solution.

“…Moreover, most of the azo dyes and degradation product of most of the dyes are cytotoxic [6] or carcinogenic [7]. Hence, the government legislation on discharge of dye effluents is becoming more and more stringent, especially in developed countries [8] and it is expected that this legislation will also become more stringent in the developing countries in near future. Hence, there is an urgent need to develop an economical treatment system for the treatment of wastewaters containing dyes.…”

“…Moreover, the degree of dye fixation on a fibre varies depending on the type of fibre to be dyed and the dying parameters. For sulphur dyes, the percentage of non-fixed dye that may be discharged in the effluent is around 25 to 30% [3]. This is why their wastewaters carry numerous and different pollutants diluted in a large amount of water.…”

The aim of our work is to compare the performances and the quality of treated water of a Tunisian textile industry through a conventional activated sludge (CAS) and a membrane bioreactor (MBR). During the first period, CAS and MBR1 worked under similar biological conditions (MLSS of 4-6 g.L -1 ). MBR showed a better global efficiency. Permeate of MBR was always free from TSS and turbidity whereas CAS treated water contained TSS and turbidity varying respectively between 0 and 0.13 g.L -1 and 10 and 20 NTU. If colour and soluble COD removal efficiency was closed (95% and 97%), it appeared necessary to add coagulant in the CAS to insure an adequate sludge settling and complete the colour removal. During the second period, the sludge retention time was increased in the MBR2 in order to reach 8-10 g.L -1 of suspended solids. The COD effluent value was further reduced (MBR2: 50 mg.L -1 , MBR1 150 mg.L -1 and CAS 180 mg.L -1 ). The SRT allows a reduction of 20% of the sludge production but this effect was counterbalance by rheological sludge properties. Furthermore, the MBR has shown great aptitude to withstand high loading rate variations and to product a constant quality effluent.
