“…On the other hand, RO membranes permit complying with the most stringent regulations for public health and environment protection. Both types of membranes are already applied in the management of industrial eluents of very diferent sectors, such as stainless steel [40], energy cogeneration [41], nuclear power [42], textile and tannery [43][44][45][46][47], coking [48,49], carwash [50], pulp and paper [34,51], pharmaceutical [52], and agro-food industries, such as dairy [13], tomato [12], and olive oil [5][6][7][8][9][10]24], among others. However, again, the problem of fouling is always present in the treatment of any kind of eluent by NF and RO membranes.…”

“…Ellouze and Tahri (2012) found that the use of microfiltration (MF) as pretreatment for NF when compared with C/F altered the treatment performances in pollutants removal regarding color (96.2 % with MF and 92.8 % with C/F) and salt removal (26 % with MF against 15.7 % with C/F). Rozzi et al (1999) found that COD and color removal were almost 70 and 95 %, respectively, in most cases when MF is coupled with NF as a pretreatment.…”

Textile effluents are considered among the most polluted wastewaters all over the world. Among different textile processes, dyeing is the operation that produces the most important amounts of chemical pollution. Many studies have been carried out toward the treatment of these hazardous effluents, and a variety of techniques have been applied for this aim. In this work, the effluents coming from different steps of the dyeing cycle were treated following different mixtures of baths using membrane technology. Nanofiltration (NF) experiments were performed for color removal, but membrane fouling still a major limitation. To enhance NF performances, microfiltration (MF) was carried out as pretreatment to NF. The results showed almost above 99 % of color and turbidity removal and also an important decrease in COD, chloride and salts contents with an improvement in the MF and NF stabilized fluxes of different mixtures compared to that corresponding to the dyeing effluent treated separately. In order to accomplish a full reuse cycle, dyeing experiments were performed using the combined system (MF/NF) permeates. Results were evaluated regarding total color difference between samples and a standard test done with fresh water.

“…Moreover, other treatment methods like adsorption [6,7], membranes [8][9][10], electrocoagulation [11,12], advanced oxidation process (AOP) [13,14] and biological processes [15,16] have been used to remove textile dyes reported in literature.…”

In this study, textile wastewater has been characterized and was found to contain very high colour and total organic carbon (TOC). Fenton, Electro-Photo Fenton reagents along with combination of natural coagulants were examined for the degradation of textile dye at various dose rate and pH. The results showed that Fenton reagent at a dose rate of 0.2 mL FeSO4 (0.25 N), 5 mL H2O2 and 0.5 mL H2SO4 gave best reduction of colour 87 % and TOC 56 %. Electrophoto Fenton was found to be effective for treatment of textile wastewater but expensive as it required energy. Sludge obtained after treatment was made metal free by acid digestion and then converted into compost. Best compost was prepared from metal free sludge in combination with dry leaves and sewerage sludge containing organic matter 91.27 %, cation exchange capacity 80 meq/100 g and C/N ratio18: 17.
