Os elementos de membrana de nanofiltra\u00e7\u00e3o da s\u00e9rie NF98 adoptam Proshare\u00ae<\/sup> membrana composta multicamada patenteada. Estas membranas fornecem o dobro do fluxo das membranas TFC tradicionais e funcionam a uma press\u00e3o pelo menos 50% inferior, o que as torna um substituto superior para as membranas NF270, XC-N, DL, DK e outras membranas TFC tradicionais.<\/p>\n

\n\tn<\/span><\/span> A superf\u00edcie da membrana NF98 \u00e9 super hidrof\u00edlica, com excelente desempenho anti-incrustante e longa vida \u00fatil;
\nn<\/span><\/span> O fluxo da membrana NF98 \u00e9 geralmente 30% mais elevado do que o TFC tradicional, e alguns modelos chegam a ter at\u00e9 2 vezes mais fluxo, resultando numa redu\u00e7\u00e3o significativa de energia;
\nn<\/span><\/span> Elevada taxa de rejei\u00e7\u00e3o de sais divalentes >98% (sulfato, ferro, metais pesados, etc.) e permite a passagem de sais monovalentes;
\nn<\/span><\/span> Elevada remo\u00e7\u00e3o de compostos org\u00e2nicos, tais como pesticidas, herbicidas, antibi\u00f3ticos e precursores de THM, etc.<\/p>\n<\/div>\n

NF98 series nanofiltration membrane elements adopt Proshare\u00ae proprietary multi-layer composite membrane. Nano-level and ultra-thin hydrophilic coating technology endows excellent anti-fouling ability.These membranes deliver twice the flux of traditional TFC membranes and operate at least 50% lower pressure, making them a superior replacement for NF270, XC-N, DL, DK, and other traditional TFC membranes.   Key Features […]<\/p>","protected":false},"author":1,"featured_media":4405,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[3],"tags":[],"acf":[],"_links":{"self":[{"href":"https:\/\/www.psimembrane.com\/pt\/wp-json\/wp\/v2\/posts\/4241"}],"collection":[{"href":"https:\/\/www.psimembrane.com\/pt\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.psimembrane.com\/pt\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.psimembrane.com\/pt\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.psimembrane.com\/pt\/wp-json\/wp\/v2\/comments?post=4241"}],"version-history":[{"count":16,"href":"https:\/\/www.psimembrane.com\/pt\/wp-json\/wp\/v2\/posts\/4241\/revisions"}],"predecessor-version":[{"id":5163,"href":"https:\/\/www.psimembrane.com\/pt\/wp-json\/wp\/v2\/posts\/4241\/revisions\/5163"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.psimembrane.com\/pt\/wp-json\/wp\/v2\/media\/4405"}],"wp:attachment":[{"href":"https:\/\/www.psimembrane.com\/pt\/wp-json\/wp\/v2\/media?parent=4241"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.psimembrane.com\/pt\/wp-json\/wp\/v2\/categories?post=4241"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.psimembrane.com\/pt\/wp-json\/wp\/v2\/tags?post=4241"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
