“…Dyes in natural waters reduce their transparency, impede photosynthesis, impair plant and animal growth, affect the solubility of oxygen and the self-cleaning process. There are many conventional (chemical and physical) methods of wastewater treatment reducing the concentration of dye contaminants (Avdicevic et al, 2017;Borges et al, 2016). They are often expensive and cause waste disposal problems.…”

This paper discusses the adsorption of Direct Orange 26 azo dye on sunflower husk -an agricultural waste product. During the study, sorption kinetics and equilibrium as well as sorption capacity of the husk were investigated. The adsorption kinetics was analyzed using pseudo-first and pseudo-second order equations, which indicated a chemical sorption mechanism. The sorption equilibrium was approximated with the two-parameter Freundlich and Langmuir equations and the three-parameter Redlich-Peterson equation. The main experiments were carried out in a laboratory adsorption column under different process conditions. Experimental data were interpreted with the Thomas model, based on the volumetric flow rate, initial composition of the feed solution and mass of the adsorbent. The results of modeling the adsorption equilibrium, adsorption kinetics and adsorption dynamics were evaluated statistically.

“…The ceramic membrane was found to be the most demanding of all tested membranes regarding the recovery of its normalized permeate flux. The chemical cleaning procedure is described in detail in (Zebić Avdičević et al, ). Permeate normalized flux was measured after each cleaning step and compared to initial value.…”

This study investigates the performance of three ultrafiltration membranes, i.e. a submerged polyethylene (PE) hollow fibre membrane, a multibore polyethersulfone (PES) membrane and a tubular multichannel ceramic membrane in the textile mercerization wastewater treatment. Experiments were carried out on two laboratory dead end membranes and on a cross flow membrane set‐up using wastewater with and without the addition of MgCl2 as a coagulant. Investigation into energy consumption was also carried out. According to the obtained results, the submerged membrane could be used as the pretreatment of mercerization wastewater to significantly reduce the amount of suspended solids, to remove organic carbon and to decrease turbidity. The results showed that the tested membranes could be used for the treatment of wastewater from the textile mercerization process in terms of permeate quality. The cross‐flow ultrafiltration consumes far more energy than the dead‐end process.

“…The effect of long-term chemical cleaning with sodium hypochlorite on the tubular ceramic NF membranes was investigated because it is known as the most effective cleaning agent for (organically) fouled ceramic membranes [2,6,17,21]. The permeability and MWCO were tested after 100 h of chemical cleaning with 1% sodium hypochlorite to simulate the cleaning intensity of one year of operation, assuming five days of continuous filtration followed by 1.33 h of chemical cleaning with 1% sodium hypochlorite for 365 days [17].…”

“…Ceramic membranes have proven to be effective for drinking water treatment [2]. In literature, studies can also be found on the treatment of water streams with a high organic load originating from various industries, such as the treatment of textile industry waste streams, both on the laboratory [1,5,6] and pilot scale [7]. In addition, the pulp and paper industry has interest in the use of ceramic membranes since its wastewater is one of the major sources of industrial water pollution.…”

Quantifying defects in ceramic tight ultra-and nanofiltration membranes and investigating their robustness Kramer, F. C.; Shang, R.; Scherrenberg, S. M.; Rietveld, L. C.; Heijman, S. J.G. A B S T R A C TOne of the perceived benefits of ceramic membranes is their robustness, which makes them suitable for treating high organic load waste streams. In particular, ceramic tight ultrafiltration (tUF) and nanofiltration (NF) form an important barrier against small colloids and organic molecules. In order to achieve this barrier, the quality of the membranes should be uncompromised.An extension on a commonly used size exclusion method was developed in order to quantify defects in membranes and calculate the MWCO accurately excluding the defects. This approach gives a better representation of the membrane quality than the original method. The quality of a broad range of commercial ceramic membranes was investigated by determining the (i) hydraulic permeability, (ii) molecular weight cutoff, and (iii) quantitative defects. Several membranesboth tubular and disc membranes, selected from various supplierswere tested to investigate their variability. Furthermore, the robustness of tubular NF membranes was studied by monitoring the effect of long-term exposure to sodium hypochlorite, which is commonly used to mitigate organic fouling.The results showed that batches of both tubular and disc membranes of different pore size and suppliers included membranes with defects. Furthermore, the long-term treatment of tubular ceramic membranes with sodium hypochlorite negatively affected, beyond expectation, the quality of the membranes. The separation layer in these membranes was not notably compromised by sodium hypochlorite exposure, but the end seal layer was damaged.
