Abstract
Piezoelectric modified membranes (PMMs) synergizing piezoelectric energy conversion with membrane separation, have emerged as a groundbreaking innovation in water treatment. This review traces historical evolution of piezoelectric materials from their discovery (1880s) to modern integration into membrane systems (2000s-2024), identifying key developmental phases. Critical performance parameters like piezoelectric coefficients (d₃₃), electromechanical coupling factors (k), and other dielectric properties (ε, tanδ, Qm, N) are rigorously analyzed to establish PMMs selection criteria in water treatment. Piezoelectric materials and mechanistic insights into piezoelectricity generation are elucidated, emphasizing how lattice distortion-induced charge redistribution enables mechanical-to-electrical energy transduction. Common fabrication processes are evaluated to provide guide on pore structure, piezoelectric dispersion, and poling stability. Poling challenges in fabrication are recapitulated, that electrical breakdown possibly mitigated via parameter/material optimization, enhancing performance for water treatment. PMMs demonstrate superior antifouling performance and pollutant rejection across diverse scenarios, involving of drinking water purification, hypersaline effluent treatment, and industrial wastewater remediation. Integration of PMMs with physico-chemistry methods (photo-catalysis, advanced oxidation, adsorption, and electrochemical processes), further enabled synergistic removal of persistent pollutants meanwhile showed energy-saving. Challenges in PMMs integration systems are discussed, future directions prioritize to study multifunctional PMMs combining other technologies, to offer transformative potential for next-generation water treatment.
期刊介绍:
The Journal of Water Process Engineering aims to publish refereed, high-quality research papers with significant novelty and impact in all areas of the engineering of water and wastewater processing . Papers on advanced and novel treatment processes and technologies are particularly welcome. The Journal considers papers in areas such as nanotechnology and biotechnology applications in water, novel oxidation and separation processes, membrane processes (except those for desalination) , catalytic processes for the removal of water contaminants, sustainable processes, water reuse and recycling, water use and wastewater minimization, integrated/hybrid technology, process modeling of water treatment and novel treatment processes. Submissions on the subject of adsorbents, including standard measurements of adsorption kinetics and equilibrium will only be considered if there is a genuine case for novelty and contribution, for example highly novel, sustainable adsorbents and their use: papers on activated carbon-type materials derived from natural matter, or surfactant-modified clays and related minerals, would not fulfil this criterion. The Journal particularly welcomes contributions involving environmentally, economically and socially sustainable technology for water treatment, including those which are energy-efficient, with minimal or no chemical consumption, and capable of water recycling and reuse that minimizes the direct disposal of wastewater to the aquatic environment. Papers that describe novel ideas for solving issues related to water quality and availability are also welcome, as are those that show the transfer of techniques from other disciplines. The Journal will consider papers dealing with processes for various water matrices including drinking water (except desalination), domestic, urban and industrial wastewaters, in addition to their residues. It is expected that the journal will be of particular relevance to chemical and process engineers working in the field. The Journal welcomes Full Text papers, Short Communications, State-of-the-Art Reviews and Letters to Editors and Case Studies
