“…Therefore, textile dyeing wastewater treatment has received more attention in the last few decades [2][3][4]. Different techniques are used for removing hydrophobic dyes, such as electron oxidation, ozonation, electro-kinetic coagulation ion, membrane filtration and microbial degradation [5][6][7][8][9][10]. These techniques have some advantages and disadvantages over the other techniques.…”

In this study, we investigated the photo-degradation efficiency of PbSe-G-TiO2 ternary nanocomposite under visible light irritation using rhodamine B as standard dye, A nanocomposite was synthesized by ultra-sonication technique and characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Raman spectroscopic analysis and UV-visible absorbance spectra analysis. The results indicate that PbSe-G-TiO2 ternary nanocompsite has excellent stability and good photodegradation efficiency than PbSe-G and TiO2-G nanocomposite which is approximately 92.5 % of rhodamine B degradation after visible light irradiation for 180 min.

“…13 Separation factors for different reactive dyes of greater than 98.5% have been achieved using nanofiltration membranes. 14 The most important parameters in economic terms for the direct reuse of dye bath wastewaters are the flux and the recovery rate of sodium chloride. Consequently, current studies have been orientated to maximise these parameters.…”

The treatment and reuse of industrial wastewaters by membrane processes has become more attractive in the last few years due to constraints on water usage. The aim of this study was to investigate the direct filtration of reactive dye house wastewaters by nanofiltration membranes based on permeate flux, and sodium chloride and colour removal. Experiments were performed using both synthetic and industrial dye bath wastewaters with the fluxes of the industrial dye bath wastewaters lower than those of the synthetic solutions. The effects of operating conditions such as pressure and pH were assessed. Studies with DS5 DK type (polysulfone-polyamide) membranes showed that nanofiltration membranes are suitable for direct treatment of wastewaters and the permeate quality was appropriate for reuse in the dyeing process. Pre-treatment and neutralisation were important for recovery of large amounts of salt and water from the permeate stream. Neutralisation of the solution with HCl rather than H 2 SO 4 gave a better permeate from the point of view of the reuse. The highest permeate flux and colour removal and the lowest salt removal were achieved with the HCl neutralisation.  2003 Society of Chemical IndustryKeywords: nanofiltration; neutralisation; reactive dye; membrane fouling; NaCl recovery INTRODUCTIONAs groundwater levels decrease and industrial water prices increase, there is an emphasis on identifying and investing in new water sources for future demands. Such alternative processes include desalination of brackish and sea water, and the reclamation and reuse of wastewaters. Several new unit processes for water and wastewater treatment such as membrane technology have been used in desalination and reclamation of both municipal and industrial wastewaters.

“…Analyzed from the structure of adsorbent and contaminate molecule, it is known that the adsorption of these charged dye groups onto the adsorbent surface is primarily influenced by the surface charge which is in turn influenced by the solution pH [18]. Figure 7 shows the effects of initial MB concentrations (5,10,20,30,40, and 50 mg/L) on BG-La-1∼5 and undoped mesoporous bioactive glasses (BG-1∼5). It can be easily observed that the removal rates of BG-La-1∼5 are higher than BG-1∼5, and the removal rate decreased with the increase of initial MB concentrations.…”

“…In particular, organic pollutants [1] that include dyes [2,3] and agricultural wastes [4] are released into the environment and can be transported over long distances in the atmosphere, water, and land. Therefore, in order to purify water, many technology have been developing and developed, such as membrane filtration technology [5], coagulation and flocculation technology [6], electrochemical oxidation technology [7], adsorption technology [8][9][10], biological treatment technology [6,11], and advanced oxidation process (AOP) [12]. However, some of the techniques shown in the effect are not ideal in practice.…”

A series of La-doped mesoporous bioactive glass (BG-La) materials with excellent biosafety and hypotoxicity have been prepared and tested as adsorbent. The study was aimed to evaluate the possibility of utilizing BG-La for the adsorptive removal of methylene blue (MB) from aqueous solution and test the adsorption and desorption behavior of this new material. The process parameters affecting adsorption behaviors such as pH, contact time, and initial concentration and the photocatalytic degradation of MB were systematically investigated. The result showed that BG-La had excellent removal rate (R) of MB, and BG-La showed better photocatalytic effect than undoped mesoporous bioactive glass (BG). Furthermore, the MB loaded BG-La was easily desorbed with acid solution due to its electronegativity and mesoporous structure. The result indicated that these materials can be employed as candidates for removal of dye pollutant owing to their high removal rate, excellent photocatalytic effect, desorption performance, and their reusability.
