“…In addition, the RO system is also low capital cost, easy to install, operate and maintain (Atab, Smallbone, & Roskilly, 2016). Due to these advantages, RO process has been applied for concentration many kinds of juices, such as: apple (Ahmad et al, 2020), pomegranate (Bagci, Kahvecioglu, Gulec, & Bagci, 2020), camu—camu (Rodrigues et al, 2020), Zhang, Fouda, Matsuura, & Chan, 1991 proved that concentration of green tea extract could be conducted by reverse osmosis membranes at bench scale. Thus, it is potential to apply RO process for concentration of waste fresh tea leaf.…”

This paper focused on the concentration of waste fresh tea leaf extract, byproduct of tea processing, by application of reverse osmosis. The concentration was carried out by plate and frame crossflow system equipped HR98PP membrane, operating as concentration mode with full recirculation of retentate. Results show that permeate flux increased with increase in operating pressure. Modeling of permeate flux based on osmotic pressure model at 30 and 40 bar of operating pressure was proposed. Hermia's model was applied for analyzed the membrane fouling in operation process. Good agreement between complete pore blocking model and experimental data was found. The recovery yields and contents of total solid (TS), total polyphenols (PPs) and antioxidant capacity (AC), consequently effectiveness, at 40 bar of operating pressure were higher than those at 30 bar. At 40 bar of operating pressure and 7.57 of concentration factor, the recovery yields of TS, PPs, and AC were 83.7, 85.1, and 79.6%, respectively. Contents of TS, PPs, and AC in retentate and permeate were 64.62 and 1.91 g/L; 25.82 and 0.61 g GAE/L; 97.87 and 3.35 mM TEAC, respectively. Maximum theoretical content of TS at 40 bar was estimated as 341 g/L. Results imply that it is potential to apply reverse osmosis for concentration of waste fresh tea leaf extract to produce instant powder with high content of polyphenols. Practical applications The concentration of waste fresh tea leaf extract by reverse osmosis membrane Modeling of permeate flux in reverse osmosis Fouling mechanism was analyzed by Hermia's model. Recovery yields and contents of total solid, total polyphenols and antioxidant capacity in concentrate against concentration factor were estimated.

“…Modeling and simulation are relatively cheaper, robust, and fast techniques as compared to the experimental methods, and if the model parameters are carefully estimated, the validated model can be used to replicate the experimental data and predict the scaling up of the process. Mass and heat transfer modeling of HFMCs is inevitable to study the concentration and flux profiles, to investigate the solute transport, to categorize the controlling resistance, for the optimization of the process operating parameters, and to scale up the process [13]. Scale-up of HFMC has not been widely studied for OMD in salt recovery during crystallization.…”

“…Similarly, the effect of physical properties was considered constant during the concentration process. Ahmad et al [13] studied the RIS model for osmotic membrane evaporation of fruit juices and found that physical properties like viscosity and density variations during the process had a significant effect on water flux. Ni et al [22] studied the effect of temperature polarization in direct contact membrane distillation for NaCl concentration and observed that temperature polarization was enhanced with the increase of feed temperature and the decrease of feed and permeate velocity.…”

Background In this research work, a coupled heat and mass transfer model was developed for salt recovery from concentrated brine water through an osmotic membrane distillation (OMD) process in a hollow fiber membrane contactor (HFMC).The model was built based on the resistance-in-series concept for water transport across the hydrophobic membrane. The model was adopted to incorporate the effects of polarization layers such as temperature and concentration polarization, as well as viscosity changes during concentration. Results The modeling equations were numerically simulated in MATLAB® and were successfully validated with experimental data from literature with a deviation within the range of 1–5%. The model was then applied to study the effects of key process parameters like feed concentrations, osmotic solution concentration, feed, and osmotic solution flow rates and feed temperature on the overall heat and mass transfer coefficient as well as on water transport flux to improve the process efficiency. The mass balance modeling was applied to calculate the membrane area based on the simulated mass transfer coefficient. Finally, a scale-up for the MD process for salt recovery on an industrial scale was proposed. Conclusions This study highlights the effect of key parameters for salt recovery from wastewater using the membrane distillation process. Further, the applicability of the OMD process for salt recovery on large scale was investigated. Sensitivity analysis was performed to identify the key parameters. From the results of this study, it is concluded that the OMD process can be promising in salt recovery from wastewater.
