The production of olive oil generates wastewater with a high organic load and toxicity due to the concentration phenolic compounds. In recent years, study on treatments these waters has been intensified together search for process recover compounds their great antioxidant potential. All this aim implementing concept circular economy. study, four different ultrafiltration membranes were evaluate...

The purpose of this study was to compare the presence or absence of UV irradiation on the separation performance and morphology of the TiO2-assembled thin film membranes (in different concentrations). Furthermore, an attempt was made to show and compare the effect of the presence of TiO2 nanoparticles in aqueous and organic phases during the interfacial polymerization proc...

To the Editor: Ultrafiltration is a standard method for separating free T3 and free T4 from serum proteins and proteinbound hormone (1, 2 ). It is expected that free T3 and free T4 in aqueous solutions will accompany water as water moves across semipermeable membranes, a process that results in equal concentrations of free T3 and free T4 in the aqueous solutions on opposite sides of semipermeab...

Suitable medium for production of milk clotting enzyme (MCE) by Bacillus subtilis (natto) Takahashi in submerged liquid-state fermentation was screened, the nutrient factors affecting MCE production was optimized by response surface methodology. The MCE production by B. subtilis (natto) Takahashi was increased significantly by 428% in the optimal medium developed. The MCE was filtered and conce...

Materials Unless otherwise stated, all chemicals and solvents were purchased from commercial suppliers and used as received. PEGylated SMCC (succinimidyl 4-(N-maleimidomethyl)cyclohexane-1-carboxylate) cross-linker (SM(PEG) 2), trans-4-Cycloocten-1-yl 2,5-dioxo-1-pyrrolidinyl carbonate (TCO-NHS) and benzylamino tetrazine N-hydroxysuccinimidyl ester (Tz-NHS) were purchased from Sigma-Aldrich. Co...

Several forward osmosis (FO) experiments were carried out using aqueous solutions of sodium chloride (NaCl) in different concentrations, as draw solution (DS), and freshwater, feed water (FW). The conducted at a constant temperature ~20°C symmetric cellulosic membrane two grades their values the molecular weight cut-off (MWCO), which is related to mean pore diameter. This study investigates eff...
