This review analyses laboratory, pilot and industrial‐scale technologies available for sulfate removal from water produced for human consumption, from naturally occurring sulfur water and that resulting from human activities. Most of them exceed 90% removal efficiencies. However, the concentrations treated in each study were different; some technologies evaluate concentrations below recommended limits (250 mg L−1), while others evaluate much higher concentrations but require previous treatments. The technologies with higher energy requirements such as reverse osmosis and ion exchange have better removal efficiencies but require larger initial investments and have higher operational costs. Biological treatments, on the other hand, with lower energy and material requirements, are less expensive but require long retention times and depend on the season of the year and/or environmental conditions. Lastly, adsorption removal technologies fall in the middle, especially for energy requirements and operational costs and retention times. This review shows that although there are a variety of sulfate removal technologies suitable for use, there is still room for a novel methodology that removes sulfates from a wider range of concentrations more economically, more effectively and in less time than what is currently available.","PeriodicalId":23753,"journal":{"name":"Water and Environment Journal","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42379826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the higher cost of electrodes and poor performance limit its scale‐up, and there is a need to focus on a cost‐effective electrode towards economic impacts. Among the various waste resources, plastic sources would be the better precursor for carbonization as the plastic‐derived carbon possess enhanced surface properties and high electrochemical stability. Further, the carbonization of plastic products towards electrode minimizes greenhouse gas emissions, maintains environmental sustainability and achieves a dual benefit of circular economy with water reclamation. This paper highlights the overview of CDI, the significance of electrodes in CDI for electrosorption studies, various synthetic routes of plastic‐derived carbon, and its properties that help the researchers to focus on zero waste discharge‐based CDI process.","PeriodicalId":23753,"journal":{"name":"Water and Environment Journal","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49480177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their effects on P‐BrA reduction and degradation were investigated through factors such as impressed voltage and cosubstrate type. The P‐BrA residue and degradation in wastewater were analysed quantitatively through analytical testing methods, such as ultraviolet–visible, cyclic voltammetry, high‐performance liquid chromatograph, and scanning electron microscopy. The results showed that under the cathode potential of 0.5 V, electrons and electroactive microorganisms generate coupling action to accelerate the degradation of P‐BrA, reaching 94.94%. Moreover, the addition of carbon source organisms, such as glucose and sodium acetate, can facilitate the degradation of P‐BrA in the cathode chamber on the precondition that the electroactive anaerobic microbial C/N ratio was satisfied, both reaching over 90%. In addition, the microbial community diversity and richness of bioelectrochemistry system were enhanced after bioaugmentation. The increase in the Anacrolincalcs, Betaproteobacteriales, and Micrococcales also played an important role in the granulation of bioelectrochemistry system and the removal of characteristic pollutants.","PeriodicalId":23753,"journal":{"name":"Water and Environment Journal","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45054377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The focus was on the operational ranges reported in the literature capable of achieving better granule properties, good stability and high removal capacities. This review identified that hydraulic retention time (HRT), light intensity (LI) and light/dark periods were the most influential operating factors on the formation, stability, settleability and organic pollutant removal efficiency of ABGS. The discussion argued that ABGS systems enhance industrial and domestic wastewater treatment due to additional advantages that provide the symbiotic interactions to process performance, maintaining lesser operating costs concerning aerobic granular sludges (AGS) and microalgae consortia. This review will improve the understanding of the operation of ABGS systems and thus further expand possible operating combinations that help to enhance microbial interactions, microalgae growth and external aeration self‐sufficiency in further research with a focus on its scaling up.","PeriodicalId":23753,"journal":{"name":"Water and Environment Journal","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47316090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
