Abstract
Microbial flocculants have attracted tremendous attention because of its extraordinary flocculating activity and degradability to create a green and healthy environment. Using microbial flocculants to partially replace chemically synthesized agents is a sustainable strategy. Currently reported literatures lack a deep correlation in terms of structure-flocculation activity relationship, flocculation mechanism and the integration with intelligent technology. There is also a lack of systematic sorting and analysis of the recent findings and pioneering applications of microbial flocculants. This review comprehensively summarizes their sources, unique molecular structure and flocculation mechanism. It also delves into their applications in five types of wastewater. The factors that limit the widespread use of microbial flocculants are discussed. To overcome these limitations, this review summarized and deeply discussed five recent progress of microbial flocculants. Finally, it presents a viewpoint that incorporate innovative technologies and methodologies to facilitate their advancement into a new developmental phase (The combination of microbial flocculant with biotechnology and AI are feasible directions). This review will assist in the comprehensive understanding of the microbial flocculant and provides novel insight into the challenges posed by wastewater pollutants.
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
