“…The characteristics of these wastewaters depends on the type of process but in general it produces wastewaters of great chemical complexity and diversity including many dyes and chemicals containing trace and heavy metals such as Cr, As, Cu and Zn, nonbiodegradable highly persistent organics and pesticides. Therefore, due to existence of persistent organics and poor biodegradability, advanced treatment processes are required, especially when the goal is reusing the treated wastewater [92][93][94]. For this reason, membrane technology can be considered as an efficient candidate for providing high quality permeates.…”

“…As an industrial example, in 2004, Societe d'Impression d'Hem(SIH), one of the major textile companies in France, installed Pall Membralox®ceramic ultrafiltration unit with a total filtration area of 432 m 2 in combination with biological treatment to treat its effluent with 10000-15000 mg/L COD concentration. The new installation was capable to recycle about 50% of the treated effluent for use as washing water for the printing machines which led to significant reduction in city water consumption consequently, remarkable reduction in operational cost [127].As mentioned before, due to existence of persistent organic pollutants (POPs) in textile effluents which are highly persistent in terms of biodegradability, and also with large variation in produced wastewater composition in different stages, treatment of textile effluent is a complex process and advanced techniques are necessary[93]. Technically, employing ceramic MF and UF as the pretreatment steps before NF and RO is the best option to textile wastewaters, which contains high concentrations of COD/BOD and TDS.Ceramic membrane pretreatment was found reducing the upstream membrane replacement frequency because of their superior chemical stability and resistance to harsh cleaning agents.…”

This paper presents a review of the previous laboratory analysis and case studies on the application of the pressure-driven ceramic membrane technology for treatment of industrial wastewaters. Ceramic membranes has attracted remarkable interests in recent decades for industrial wastewater treatment because of their superior characteristic such as high fluxes , reliable working lifetime under aggressive operating conditions and ease of cleaning. The literature review revealed that the efficiency of this technology has been proven in a wide variety of wastewaters from different industries and activities including pulp and paper, textile, pharmaceutical, petrochemical, food and mining. However, there are still challenges and questions for this technology that need to be addressed in future researches such as investment cost optimisation by introducing new fabrication technologies, selectivity, permeability and packing densities improvement, fouling minimisation and proposing scale up based on experimental research results.

Separation of Peptides with Forward Osmosis Biomimetic Membranes

Forward osmosis (FO) membranes have gained interest in several disciplines for the rejection and concentration of various molecules. One application area for FO membranes that is becoming increasingly popular is the use of the membranes to concentrate or dilute high value compound solutions such as pharmaceuticals. It is crucial in such settings to control the transport over the membrane to avoid losses of valuable compounds, but little is known about the rejection and transport mechanisms of larger biomolecules with often flexible conformations. In this study, transport of two chemically similar peptides with molecular weight (Mw) of 375 and 692 Da across a thin film composite Aquaporin Inside™ Membrane (AIM) FO membrane was investigated. Despite the relative large size, both peptides were able to permeate the dense active layer of the AIM membrane and the transport mechanism was determined to be diffusion-based. Interestingly, the membrane permeability increased 3.65 times for the 692 Da peptide (1.39 × 10−12 m2·s−1) compared to the 375 Da peptide (0.38 × 10−12 m2·s−1). This increase thus occurs for an 85% increase in Mw but only for a 34% increase in peptide radius of gyration (Rg) as determined from molecular dynamics (MD) simulations. This suggests that Rg is a strong influencing factor for membrane permeability. Thus, an increased Rg reflects the larger peptide chains ability to sample a larger conformational space when interacting with the nanostructured active layer increasing the likelihood for permeation.

“…[1,2] In addition, NF membranes provide high rejection of organic molecules or multivalent ions having molecular weights ranging from 150 to 1000 with a relatively high water flux, but lower operating pressure compared to RO. [3,4] These characteristics led to a growing list of applications for NF at industrial sectors especially in water softening, [5,6] purification of drinking water, [7,8] wastewater treatment and reclamation, [9,10] solvent recovery, [11,12] etc.…”

Nanofiltration (NF) is a membrane-based separation process having significant potential for the treatment of industrial effluents to enable water reuse. It has the ability to remove low molecular weight trace contaminants from water, which cannot be separated by conventional treatment methods. In the present investigation, a thin film composite polyamide membrane was synthesized by interfacial polymerization technique and evaluated for the treatment of biscuit industrial effluent. The synthesized membrane was characterized using Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, and scanning electron microscopy to elucidate structure and intermolecular interactions, crystallinity, thermal stability and cross-sectional morphology, respectively. The influence of operating parameters such as feed pressure 0-21 kg/cm 2 and total dissolved solids (TDS) of 3160 ppm on water flux and impurity rejection was determined. An average flux of 11.63 L/m 2 h was obtained at a constant pressure of 21 kg/ cm 2 . The TDS, chemical oxygen demand (COD), and biochemical oxygen demand (BOD) rejections were found to be 53.62, 80, and 74%, respectively, at a water recovery of 65%. A statistical mechanical model was used to validate the experimental data. Based on this study, a detailed economic estimation for processing biscuit effluent of 1 m 3 /h feed capacity using commercial NF system is presented. The study revealed that the synthesized NF membrane could be an effective alternative for the treatment of various industrial effluents as well as to reduce the load on reverse osmosis process for desalination of seawater and effluent treatment through high degree of COD and BOD separation.
