“…Many authors reported that feed temperature showed a remarkable influence on the permeate flux with ceramic membranes applied to MD, regardless of configuration and feed solution. This propensity is explained by the Antoine equation, which predicts an exponential relationship between the vapor pressure difference and temperature due to the higher latent heat of water evaporation and higher heat transfer coefficient, without affecting the permeate quality.…”

“…Some studies evaluated the influence of feed flow on MD performance. By decreasing the feed flow rate, permeate flux shows the same initial value but depreciates significantly over time due to the accumulation of solutes on the membrane surface . Higher feed flows exert more shear force on the membrane surface, thus reducing both membrane fouling and temperature polarization.…”

“…For ceramic membranes, the publications with high MD performance (permeate flux above 20 kg m −2 h −1 ) reported a total thickness with support ranging from 180 to 600 µm. However, two studies which also showed a high performance reported the total thickness with support of 2432 and 2500 µm . In addition, some studies that reported low permeate fluxes reported a small thickness of ceramic membranes.…”

“…Hubadillah et al and Kujawa et al proved that ceramic‐based MD can be applied to high concentrated solutions without affecting its performance because of lower fouling effect . On the other hand, many authors observed that when increasing the solute concentration at the feed side results in a decrease in permeate flux . This phenomenon is explained by Raoult's law, which states that higher solute concentrations lead to decrease in water vapor pressure.…”

“…Moreover, the decline of the permeate flux may be the result of the driving force decrease in MD due to concentration polarization caused by the increasing concentration of solute in the feed solution. However, even at higher solute concentration, a high permeate flux is still obtained . On the other hand, Garofalo et al obtained a reduction of solute rejection when increasing solute concentration …”

Membrane distillation (MD) has been increasingly studied in the past decade for its potential as a separation process of nonvolatile components. The present study demonstrates a comprehensive overview of the current progress and challenges in the application of ceramic membranes to MD based on the available state of the art.There are already published review papers about MD, but the present study focuses on ceramic membranes, which are still the few used in MD when compared to polymeric membranes. Significant issues such as membrane material, module, characteristics, and hydrophobic modification are discussed. The main operating conditions and their effects on the separation process are given. Current applications of ceramic membranes in MD are also presented. Likewise, challenges and future perspectives associated with MD performance using ceramic membranes are highlighted.A review focused on ceramic membranes applied specifically to MD will contribute for future research in order that this process achieves successful implementation in industry.

This review focuses on the research literature published in 2018 relating to thermal effects in wastewater and solid waste treatment. This review is divided into the following sections: treatment of wastewater and sludge, removal and recovery of nitrogen and phosphorus, reduction and recovery of heavy metals, membrane technology, and treatment and disposal of solid wastes.Practitioner points Thermal effect plays an important role in the treatment of wastewater and sewage sludge. Recovery of nitrogen and phosphorus from wastewater and sewage sludge offers an excellent feedstock for soil amendment. Increase of treatment temperature facilitates removal and recovery of heavy metals from water and soil environment.
