“…The color of the permeate obtained at various NaCl concentrations was shown in Figure c. This observation was in agreement with the results obtained by Alventosa‐de Lara et al during decolorization of dye/salt mixtures using ultrafiltration membrane. Also, as expected the rejection of NaCl by the membrane during MEUF was almost insignificant (less than 6%) due to smaller size of the ions compared with the membrane pore size, confirming the presence of high content of NaCl in the permeate stream, measured by conductivity.…”

The application of rhamnolipid (RHL) in micellar‐enhanced ultrafiltration (MEUF) was investigated to remove both cadmium ion (Cd+2) and crystal violet (CV) simultaneously from aqueous solution. The effects of the membrane pore size, feed conditions, and operating conditions on solute removal efficiency and permeate flux were studied. Response surface methodology (RSM) was used to obtain the optimal feed conditions. Eigenvalue analysis was performed to evaluate the nature of optimal condition. Critical micelle concentration and aggregate size of RHL in the presence of Cd+2 and CV were determined. Ultrafiltration data were used to estimate the partition coefficient, distribution coefficient and relative affinity of the pollutants, and loading capacity of RHL vesicles. Compared with chemical surfactants, the use of RHL in MEUF process with larger membrane pore size performed better in terms of process throughput. About (84 ± 1)% of initial RHL was recovered from retentate stream using acid precipitation technique, at the optimal recovery condition obtained through RSM. The experimental results obtained using optimal feed condition and RHL recovery condition matched well with the predicted results. Reclaimed RHL was successfully used two times in MEUF with rejection efficiency of 96.7% for Cd+2 and 97.8% for CV, thus, significantly lower the cost of the MEUF process.

“…Nanoporous membranes with cellulose nanocrystals is also used in the removal of various dyes such as Victoria Blue, Methyl Violet and Rhodamine dyes [71]. The disadvantages of this process such as the high pressure needed, clogging of the membrane's pores and incapability to treat large volume of effluents limit its uses [72].Also during the operation, various suspended particles such as dyes and organic matter tend to accumulate within a thin boundary layer adjacent to the membrane surface and result in membrane fouling [73] …”

Dyes are complex organic compounds which are used by various industries to colour their products. These dyes are purged from various industrial sources such as textile, cosmetic, paper, leather, rubber and printing industries. Wastewater effluents contain dyes which may cause potential hazards to the environment. Some of these dyes are toxic, carcinogenic and can cause skin and eye irritation. Therefore, many researchers have been studied the effectiveness of dyes removal from aqueous solution by different separation methods. Different separation techniques have been used for the treatment of dye-bearing wastewater such as adsorption, coagulation/flocculation, advanced oxidation technologies, ozonation, and membrane-filtration, aerobic and anaerobic degradation. All dye separation techniques have their own limitation in terms of design, operation efficiency and total cost. This review paper provides extensive literature information about dyes, its classification and toxicity together with various treatment methods into dye adsorption characteristics of several non-conventional cost effective sustainable adsorbents. The mechanism and the effects of various physio-chemical process parameters on dye adsorption are presented here.

“…[1] Reuse of the chemicals and water from industrial processes due to more stringent regulations and to improve the resource efficiency of today's society has become very important. [2][3][4][5][6][7] Textile industry processes consist of several stages: mercerization, bleaching and dyeing. These activities use from 5 to 40 times higher quantities of water than fiber weight and consequently generate large volumes of wastewater.…”

“…[3,6,[10][11][12] Today, polymeric membranes are the most commercially used, [1] but ceramic membranes have higher thermal, chemical and mechanical stability compared to polymeric membranes. [1,6,11,[13][14][15] Since wastewater from the mercerization process has high temperature and it is extremely alkaline, ceramic membranes could be the appropriate choice for its treatment. Ceramic membranes also show extended lifetime than polymeric membranes, but are considered more expensive, [16] although their cost has been continuously reduced over the last years.…”

Textile wastewaters are rated as one of the most polluting in all industrial sectors, and membrane separation is the most promising technology for their treatment and reuse of auxiliary chemicals. This study evaluates the performance of three types of tubular ceramic ultrafiltration membranes differing by mean pore size (1, 2 and 500 kDa) treating textile mercerization wastewater from a textile mill at different operating conditions: cross-flow velocity (CFV) and temperature. Acceptable results were obtained with 1 kDa ceramic membrane, with rejection efficiencies 92% for suspended solids, 98% for turbidity, 98% for color and 53% for total organic carbon at 20°C and 3 m s −1 CFV. Highest fouling effect was observed for 500 kDa membrane and lowest CFV. According to the observed results, 1 kDa membrane could be used for the treatment of wastewater from the textile mercerization process in terms of permeate quality. ARTICLE HISTORY
