摘要

Abstract <section xml:id="jctb5495-sec-0001" numbered="no"> <title type="main" xml:lang="de">BACKGROUND > Extracellular polymeric substances and microalgae stimulate membrane fouling during harvesting. The objective of the study was to compare the effect of pore formers on TiO <sub>2</sub> embedded polyethersulfone mixed matrix membranes (MMMs) to harvest <fi>Coelastrella</fi> sp. FI69. The study experimented with hydrophilic additive (polyethylene glycol), polyelectrolyte additive (polyethylenimine), inorganic additive (zinc chloride) and charged polymer (sulfonated polyetherether ketone (SPEEK)) as pore formers. </section> <section xml:id="jctb5495-sec-0002" numbered="no"> <title type="main">RESULTS > It was found that SPEEK/TiO <sub>2</sub> combination enhanced the hydrophilic property of the PES membrane surface. Also, contact angle value (55.22°) was decreased by 1.38 times that of a neat PES (76.63°) membrane. Morphology studies indicated that the TiO <sub>2</sub> particles dispersed well in the PES membrane matrix along with pore formers. The existence of super hydrophilic TiO <sub>2</sub> supported the restriction of microalgae cell attachment on the membrane surface. The filtration of alginic acid sodium solution analysis showed that PES/SPEEK/TiO <sub>2</sub> and PES/PEG/TiO <sub>2</sub> membranes support higher flux with minimal fouling percentage. Microalgae filtration studies indicated that synergistic effect of both SPEEK and TiO <sub>2</sub> on PES membrane exhibited higher water recovery percentage of 96% and equilibrium flux of 66 L m <su </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译:</span><Abstract XMLNS =“http://www.wiley.com/namespaces/wiley”type =“main”xml:lang =“en”> <title type =“main”>抽象</ title> <section XML:ID =“JCTB5495-SEC-0001”编号=“否”> <标题类型=“MAIN”XML:LANG =“de”>背景</标题> <P>细胞外聚合物物质和微藻刺激收获过程中的膜污染。该研究的目的是将孔隙成型剂对TiO <sub> 2 </ sub>嵌入聚醚砜混合基质膜(MMMS)的影响进行比较,以收获<FI> Coelastrella </ Fi> Sp。 FI69。研究了亲水性添加剂(聚乙二醇),聚电解质添加剂(聚乙烯亚胺),无机添加剂(氯化锌)和带电聚合物(磺化聚醚醚酮(Speek))作为孔成型剂。 </ p> </ section> <section xml:id =“JCTB5495-SEC-0002”编号=“否”> <标题类型=“main”>结果</ title> >它被发现是speek / tio <sub> 2 </ sub>组合增强了PES膜表面的亲水性。此外,接触角值(55.22°)降低了整洁PES(76.63°)膜的1.38倍。形态学研究表明,TiO <sub> 2 </ sub>颗粒在PES膜基质中分散孔以及孔成型器。超亲水性TiO <sub> 2 </ sub>的存在支持在膜表面上的微藻细胞附着的限制。活性酸钠溶液分析的过滤显示,PES / Speek / TiO <sub> 2 </ sub>和PES / PEG / TiO <sub> 2 </ sub>膜支持更高的助焊剂,污垢百分比最小。微藻滤波研究表明,PES膜上的Speek和TiO <sub> 2 </ sub>的协同效应表现出96%的96%和66μm的平衡通量的水恢复百分比较高 </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-33908/'>《Journal of Chemical Technology & Biotechnology》</a> <b style="margin: 0 2px;">|</b><span>2018年第3期</span><b style="margin: 0 2px;">|</b><span>共11页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Yogarathinam Lukka Thuyavan&option=202" target="_blank" rel="nofollow">Yogarathinam Lukka Thuyavan;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Gangasalam Arthanareeswaran&option=202" target="_blank" rel="nofollow">Gangasalam Arthanareeswaran;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Ismail Ahmad Fauzi&option=202" target="_blank" rel="nofollow">Ismail Ahmad Fauzi;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Parthasarathy Prakash&option=202" target="_blank" rel="nofollow">Parthasarathy Prakash;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Department of Chemical EngineeringNational Institute of TechnologyTiruchirappalli India;</p> <p>Department of Chemical EngineeringNational Institute of TechnologyTiruchirappalli India;</p> <p>Advanced Membrane Technology Research Centre (AMTEC)Universiti Teknologi MalaysiaJohor Malaysia;</p> <p>Department of Chemical EngineeringNational Institute of TechnologyTiruchirappalli India;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/180.html" title="生物工程学(生物技术)">生物工程学(生物技术);</a><a href="https://www.zhangqiaokeyan.com/clc/20827.html" title="生物化学过程">生物化学过程;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=pore formers&option=203" rel="nofollow">pore formers;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=mixed matrix membranes&option=203" rel="nofollow">mixed matrix membranes;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=alginic acid sodium salt&option=203" rel="nofollow">alginic acid sodium salt;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=microalgae&option=203" rel="nofollow">microalgae;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=hydrophilicity&option=203" rel="nofollow">hydrophilicity;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=fouling&option=203" rel="nofollow">fouling;</a> </p> <div class="translation"> 机译:孔隙素;混合基质膜;藻酸钠盐;微藻;亲水;污垢;
