Recent progress, bottlenecks, improvement strategies and the way forward of membrane distillation technology for arsenic removal from water: A review

A review on arsenic in the environment: bio-accumulation, remediation, and disposal

“…180–182 Membrane distillation could play a role in helping the water industry meet the United Nations' Sustainable Development Goals (SDGs). 183…”

“…Removal efficiencies of As reported with representative techniques are summarized in Table 6. [177][178][179][180][181][182][183][184] It can be seen from Table 6 that over 90% of As(V) can be effectively removed with adsorption, coagulation, ion exchange, and membrane methods (including NF and RO). By contrast, the removal efficiencies of As(III) are technique dependent and are apparently lower than those of As(V), which can be attributed to the possibility of As(III) existing as uncharged species (H 3 AsO 3 0 ).…”

“…[180][181][182] Membrane distillation could play a role in helping the water industry meet the United Nations' Sustainable Development Goals (SDGs). 183 Disposal of contaminated biomass Contaminated biomass from phytoextraction processes is a serious threat to both the environment and human health. Several methods have been proposed for the disposal of heavy metal-contaminated biomass, including composting, compaction, incineration, ashing, pyrolysis, direct disposal, and liquid extraction.…”

Recent progress and technical improvement strategies for mitigating ceramic membrane bottlenecks in water purification processes: A review

“…Despite progress in technical solutions for mitigating the bottlenecks of ceramic mem-INTRODUCTION Membrane technology has recently garnered significant attention and demand in various industries due to its excellent separation performance and continuous advancements in membrane module design, reducing overall costs. 1,2 It finds applications in industrial processes such as desalination, wastewater recovery, and water and wastewater treatment. [3][4][5][6] Compared to conventional separation and filtration techniques, membranes based on separation techniques are more robust, compact, and perform better.…”

“…4,7 Polymeric and ceramic membranes are the most commonly used types of membranes in membrane technology. 2 Polymeric membranes have been extensively studied since the 1990s and are widely used in water and wastewater applications. Various aspects of polymeric membranes, such as synthesis techniques and full-scale applications, have been investigated.…”
