Industrial Waste Water Treatment Nanofiltration Elements

工業(yè)污水處理納濾膜元件

Durafoul is a family series of membrane elements engineered for use with fouling-prone brackish water applications and industrial waste water treatment and reuse application. Typical applications include leachate, municipal, chemical process, textile, paper and cooling tower blow down treatment. Durafoul is designed to utilize an innovative three-layer membrane, of which a proprietary middle layer creates extreme smoothness, and provide a high rejection of salts.

durafoul是家族系列膜元件使用的工程易污染苦咸水應(yīng)用和工業(yè)廢水處理與回用中的應(yīng)用。典型應(yīng)用包括滲濾液、市政、化工過(guò)程、紡織、造紙和冷卻塔的降溫處理。durafoul旨在利用創(chuàng)新的三層膜，其中一個(gè)中間層創(chuàng)建極端平滑，并提供了高的脫鹽率。

Independent studies have demonstrated that Durafoul elements are superior to standard polyamide spiral wound membrane elements for salt removal in fouling environment. Durafoul elements retrofit existing systems to obtain stable permeate flux, reduced overall energy usage, increased membrane service life and an extension of operating time between required cleanings, which in turn reduces expenditures on required chemicals.

獨(dú)立的研究表明，durafoul元素均優(yōu)于標(biāo)準(zhǔn)聚酰胺螺旋卷式膜元件污染環(huán)境中除鹽。durafoul元素改造現(xiàn)有系統(tǒng)獲得穩(wěn)定的膜通量，降低整體能耗，提高膜的使用壽命，需要在清洗操作時(shí)間的延長(zhǎng)，這反過(guò)來(lái)又降低了對(duì)化學(xué)物質(zhì)所需費(fèi)用。

Durafoul elements feature a FRP outerwrap, standard feed spacers, and ABS ATD and central tube.

系列專有納濾復(fù)合膜元件的截留分子量為150-300道爾頓（以中性分子計(jì)算），Durafoul NF

應(yīng)用：染料去除或濃縮，重金屬去除，酸的純化，氯化鈉滲濾，糖的濃縮和分級(jí)，乳清蛋白的濃縮及脫鹽，多肽的濃縮與脫鹽

對(duì)二價(jià)和多價(jià)陰離子優(yōu)先截留，對(duì)單價(jià)離子的截留率大小與料液的濃度和組成相關(guān)，由于單價(jià)離子可透過(guò)膜，不會(huì)產(chǎn)生滲透壓，所以Durafoul NF納濾系統(tǒng)可在比反滲透系統(tǒng)更低的操作壓力下運(yùn)行。

Durafoul NF 納濾膜元件具有玻璃鋼外殼及標(biāo)準(zhǔn)濃水流道。根據(jù)需要可選用其他結(jié)構(gòu)材質(zhì)及特殊流道設(shè)計(jì)。

Durafoul NF納濾膜截留特性：對(duì)二價(jià)和多價(jià)陰離子優(yōu)先截留，對(duì)單價(jià)離子的截留率大小與料液的濃度和組成相關(guān)。以中性分子計(jì)算的膜截留分子量為150-300道爾頓。
