  • Developments and future potentials of anaerobic membrane bioreactors (AnMBRs)
    Chettiyappan Visvanathan and Amila Abeynayaka
    Abstract; Full Text (1003K)

The coupling of anaerobic biological process and membrane separation could provide excellent suspended solids removal and better biomass retention for wastewater treatment. This coupling improves the biological treatment process while allowing for the recovery of energy through biogas. This review gives a basic description of the anaerobic wastewater treatment process, summarizes the state of the art of anaerobic membrane bioreactors (AnMBRs), and describes the current research trends and needs for the development of AnMBRs. The research interest on AnMBR has grown over the conventional anaerobic processes such as upflow anaerobic sludge blanket (UASB). Studies on AnMBRs have developed different reactor configurations to enhance performances. The AnMBR performances have achieved comparable status to other high rate anaerobic reactors. AnMBR is highly suitable for application with thermophilic anaerobic process to enhance performances. Studies indicate that the applications of AnMBR are not only limited to the high strength industrial wastewater treatment, but also for the municipal wastewater treatment. In recent years, there is a significant progress in the membrane fouling studies, which is a major concern in AnMBR application.

  • New CPS-PPEES blend membranes for CaCl2 and NaCl rejection
    Chitrakar Hegde, Arun M Isloor, Mahesh Padaki, Ahmad Fauzi Ismail and Lau W.J
    Abstract; Full Text (2263K)

Carboxylated polysulfone (CPS), poly (1,4-phenylene ether ethersulfone) (PPEES), membranes were prepared and used for the separation of NaCl and CaCl2, in efficient way with less energy consumption. In this work, nanofiltration and reverse osmosis membranes were employed to the salt rejection behavior of the different salt solutions. The influence of applied pressure (1-12 bar), on the membrane performance was assessed. In CM series of membranes, CM1 showed maximum of 97% water uptake and 36% water swelling, whereas, CM4 showed 75% water uptake and 28% water swelling. In RCM series, RCM1 showed 85% water uptake and 32% water swelling whereas, in RCM4 it was 68% for water uptake and 20% for water swelling. Conclusively reverse osmosis membranes gave better rejection whereas nanofiltration membrane showed enhanced flux. CM1 showed 58% of rejection with 12 L/(m2 h) flux and RCM1 showed 55% of rejection with 15 L/(m2 h) flux for 0.1 wt.% NaCl solution. Whereas, in 0.1 wt.% CaCl2 solution, membrane CM1 showed 78% of rejection with 12 L/(m2 h) flux and RCM1 showed 63% rejection with flux of 9 L/(m2 h).

  • A novel method of surface modification to polysulfone ultrafiltration membrane by preadsorption of citric acid or sodium bisulfite
    Xinyu Wei, Zhi Wang, Jixiao Wang and Shichang Wang
    Abstract; Full Text (836K)

In membrane processes, various agents are used to enhance, protect, and recover membrane performance. Applying these agents in membrane modification could potentially be considered as a simple method to improve membrane performance without additional process. Citric acid (CI) and sodium bisulfite (SB) are two chemicals that are widely used in membrane feed water pretreatment and cleaning processes. In this work, preadsorptions of CI and SB were developed as simple methods for polysulfone ultrafiltration membrane modification. It was found that hydrogen bonding and Van Der Waals attraction could be responsible for the adsorptions of CI and SB onto membranes, respectively. After modification with CI or SB, the membrane surfaces became more hydrophilic. Membrane permeability improved when modified by SB while decreased a little when modified by CI. The modified membranes had an increase in PEG and BSA rejections and better antifouling properties with higher flux recovery ratios during filtration of a complex pharmaceutical wastewater. Moreover, membrane chlorine tolerance was elevated after modification with either agent, as shown by the mechanical property measurements.

  • Effects of ring number and baffled-ring distances on ultrafiltration in the tubular membrane inserted concentrically with a ring rod
    Ho-Ming Yeh, Chii-Dong Ho and Cha-Hsin Li
    Abstract; Full Text (716K)

The permeate flux declination along an ultrafilter membrane is due mainly to the concentrationpolarization resistance increment and the decline in transmembrane pressure. It was found in previous works that the concentration polarization resistance could be reduced in a ring-rod tubular membrane ultrafilter using the turbulent behavior. In the present study, the performance was further improved by properly and gradually decreasing the baffled-ring distance along the cross-flow channel coupled with properly adjusting the number of baffled rings. This theoretical analysis is based on the mass and momentum balances as well as the application of the resistance-in-series model. The correlation predictions are confirmed with the experimental results for dextran T500 aqueous solution ultrafiltration.

Key Words

    Research and Publication Ethics

    All the editors, publishers, researchers, and peer reviewers of Techno-Press journals strongly encourage to carefully review and follow the Committee on Publication Ethics (COPE) guidelines:

    1. Authorship
    Authorship credit should be based on
        (1) Substantial contributors to the conception or design of the work or the acquisition, analysis
       or interpretation of data for the work,
        (2) Drafting the work or revising it critically for important intellectual content,
        (3) Final approval of the version to be published, and
        (4) Agreement to be accountable for all aspects of the work in ensuring that questions related
       to the accuracy or integrity of any part of the work are appropriately investigated and resolved.
    Authors should meet these four conditions after the initial submission of a manuscript and any changes whatsoever in authorship (adding author(s), deleting author(s), or re-arranging the order of authors) must be explained by a letter to the editor from the authors concerned. This letter must be signed by all authors on the paper. Techno-Press does not correct authorship after the final acceptance unless a mistake has been made by the editorial staff. Authorship may be changed before the final acceptance when the authorship correction is requested by all of the authors involved with the manuscript. The corresponding author takes primary responsibility for communication with the journal during the manuscript submission, peer review, and publication process. The corresponding author should be available throughout the submission and peer review process to respond to editorial queries in a timely manner, and should be available to respond to critiques of the work and cooperate with any requests from the journal for data or additional information or questions about the paper even after publication.

    2. Originality, plagiarism and duplicate publication
    Submitted manuscripts must not have been previously published or be under consideration for publication elsewhere. No part of the accepted manuscript should be duplicated in any other journal without the permission of the Editorial Board. Submitted manuscripts are checked for possible plagiarism or duplicate publication upon the paper's arrival. If plagiarism or duplicate publication is detected, the manuscripts may be rejected, the authors will be announced in the journal, and their institutions will be informed. There will also be penalties for the authors. A letter of permission is required for any and all material that has been published previously. It is the responsibility of the author to request permission from the publisher for any material that is being reproduced. This requirement applies to text, figures, and tables.

    3. Conflict of interest statement
    The corresponding author must inform the editor of any potential conflicts of interest that could influence the authors' interpretation of the data. Examples of potential conflicts of interest are financial support from or connections to companies, political pressure from interest groups, and academically related issues. In particular, all sources of funding applicable to the study should be explicitly stated.

    4. Process for managing research and publication misconduct
    When the journal faces suspected cases of research and publication misconduct, such as redundant publication, plagiarism, fraudulent or fabricated data, changes in authorship, undisclosed conflict of interest, ethical problems with a submitted manuscript, appropriation by a reviewer of an author's idea or data, and complaints against editors, the resolution process will follow the flowchart provided by COPE,
    The discussion and decision on the suspected cases are carried out by the Editorial Board.

    5. Editorial responsibilities
    The Editorial Board will continuously work to monitor and safeguard publication ethics:
    * Guidelines for retracting articles;
    * Maintenance of the integrity of academic records;
    * Preclusion of business needs from compromising intellectual and ethical standards;
    * Publishing corrections, clarifications, retractions, and apologies when needed; and
    * Excluding plagiarized and fraudulent data.
    The editors maintain the following responsibilities:
    * Responsibility and authority to reject and accept articles;
    * Avoid any conflict of interest with respect to articles they reject or accept;
    * Promote the publication of corrections or retractions when errors are found; and
