|dc.description.abstract||The main objective of WP2 was to conduct a comprehensive evaluation on available pretreatment approaches for seawater, brackish water, and estuarinelbay water for membrane protection and recovery maximization. During the project promising results were obtained by UNlCAL and BGU on MBR as a means for reducing organic content from seawater as a step towards reducing fouling potentiaL It seems that the pretreatment in a MER system is effective at improving the water's quality (removal of TOC and EPS) for further process, but further economical and implemental examinations are necessary in order to adopt this treatment as an alternative pretreatment. The removal of particulate malter and organics from seawater by the use of biofiltration was investigated by UTS. Granular activated carbon (GAC) and anthracite were tested as a filter medium at two different velocities. The filtrate quality was evaluated by measuring the silt density index (SDI), modified fouling index (MFI) and turbidity removal. Both biofilters demonstrated similar behavior in terms of SDI and MFL In addition, fiber filter as pre-treatment of SWRO in terms ofMFI, SDI 10, pressure drop, turbidity and molecular weight distribution (MWD) was investigated with and without precoagulation. Submerged microfiltTation couplcd with physcio-chemical processes such as adsorption on powder activated carbon was investigated as well.||en_US|

OPUS (Open Publications of UTS Scholars) is the UTS institutional repository. It showcases the research of UTS staff and postgraduate students to a global audience. For you, as a researcher, OPUS increases the visibility and accessibility of your research by making it openly available regardless of where you choose to publish.
Items in OPUS are enhanced with high quality metadata and seeded to search engines such as Google Scholar as well as being linked to your UTS research profile, increasing discoverability and opportunities for citation of your work and collaboration. In addition, works in OPUS are preserved for long-term access and discovery.
The UTS Open Access Policy requires UTS research outputs to be openly available via OPUS. Depositing your work in OPUS also assists you in complying with ARC, NHMRC and other funder Open Access policies. Providing Open Access to your research outputs through OPUS not only ensures you comply with these important policies, but increases opportunities for other researchers to cite and build upon your work.
OPUS archives UTS research submitted for Higher Education Research Data Collection (HERDC) and Excellence in Research for Australia (ERA). It also stores digital theses and forms of scholarship that do not usually see formal publication.
When you claim (or enter) your research in Symplectic Elements, simply upload a copy of your work which can be made openly available. Symplectic provides information on which version of your work to upload. If you are unsure, please supply a copy of the Accepted Manuscript version. Ensure you check the box to "agree to the OPUS license terms".
Once uploaded, your works are automatically sent to OPUS and placed temporarily in Closed Access until reviewed by UTS Library staff.
Once items are cleared of copyright constraints and/or publisher embargoes, your work is moved to Open Access and made accessible to the public.
Instructions are available from the Symplectic User Guide or contact email@example.com for further information.
