“…However, the use of these streams does not give a true representation of the effluent from the dye bath and the effects it has on membrane performance in terms of permeate quality and recovery of chemicals for reuse. Typical textile wastewater characteristics have been outlined in the studies of Bisschops and Spanjers (2003); Aouni et al (2012); Kurt et al (2012) and Thamaraiselvan and Noel (2015). Little or no attention has previously been given to the importance of investigating the influences of the use of permeate water obtained from NF processes on the quality of the final textile product; this is a crucial aspect that requires investigation, especially in the integration of membranes for the treatment of reactive dye-bath effluent for recycling purposes.…”

“…A sludge management problem is also a limitation arising from the use of chemicals. Thus, the water quality produced does not meet the requirements for textile reuse (Ismail and Dincer, 2003;Bes-Piá et al, 2009;Van der Bruggen, 2013;Thamaraiselvan and Noel, 2015). The methods favour end-of-line treatment in which all of the waste from different processes is collected and treated.…”

“…Over the years, reclaiming of wastewater has become very important, especially in the textile industry, because of the scarcity of freshwater supply and the increasingly strict government regulations regarding effluent release into water bodies (Singh and Arora, 2011;Zahrim et al, 2011;Dasgupta et al, 2015). Various conventional methods are being used to treat textile effluents, including: biological methods (aerobic and anaerobic), physico-chemical treatment (coagulation and flocculation), adsorption, ion-exchange, and chemical treatment with oxidizing agents (Khouni et al, 2011;Thamaraiselvan and Noel 2015). The limitation of all these methods, however, is that total colour removal is not achieved and chemical byproducts are introduced.…”

The main aim of the study was to test the feasibility of using nanofiltration (NF) processes for the treatment of reactive dyebath effluents from the textile industry, in order to recover the water and chemicals (salts) for reuse purposes. The study of the reusability of nanofiltered water for dyeing has been given little or no attention. About 30% of reactive dyes remain unfixed on fibres; the unfixed dyes are responsible for the colouration in effluents. Membrane processes were employed to treat reactive dye-bath effluents to recover the salts and water. Investigations were conducted firstly with ultrafiltration (UF) used as a pretreatment for NF. Secondly, evaluations were performed for 2 types of NF membranes (SR90 and NF90), in terms of quality of permeate produced and fluxes achieved for 2 different samples of effluent. The effect of cleaning on membrane performance was assessed. A reusability test was carried out on both permeate samples for dyeing light and dark shade recipes. The use of UF as pre-treatment to NF resulted in rejection of colloidal substances > 90% and a 15% flux improvement. Permeate from NF90 had a conductivity of 76 µS/cm and total organic carbon (TOC) of 20 mg/ℓ, as compared to SR90 which had a conductivity of 8.3 mS/cm and a TOC of 58 mg/ℓ. Light shade from NF90 gave satisfactory results on dyeing, with no colour difference. However a variation in colour was noticed when the medium sample was used to dye the light shade. Both NF permeates gave satisfactory results when used to dye the dark shades. Permeate from NF90 was within the accepted range for reuse, while permeate from SR90 had a higher salt recovery. Chemical cleaning resulted in 80% flux recovery. From the reusability test it was concluded that permeate from NF90 met the reuse criteria for feed water to the dye bath.

“…Some research in textile wastewater treatments have been done by coagulation, adsorption, membrane separation and extraction. [6][7][8][9][10][11][12][13][14] Those conventional technologies have their own advantages and disadvantages. Emulsion liquid membrane (ELM) as an alternative of solvent extraction provides advantages of combining extraction and stripping process in a single step, thus minimising the equipment as well as processing time.…”
