NASA在太空梭里汙水與太空人的尿液進行純化再次利用(因為水很重要...不能說排放就排放)
所利用的科技就是我們現在常見的 Reverse Osmosis

在1970年代 美國陶氏化學....發明了低水壓逆滲透膜...就開啟了淨水界的一些歷史了
陶氏化學(Dow Chemical Company)在2015年與 杜邦公司(DuPont)整併成為了全世界最大的化工巨擘....
長期喜愛filmtec RO的消費者 有沒有注意到....
DOW FILMTEC™ TW30-1812-50 最近已經悄悄改版了
進而推出了三款家用的RO膜
AQUALAST 1812(藍色)
FilmTec™ TW30-1812-50HR(藍色)
TapTec™ TT-1812-50(綠色)
那這三個家用的訴求有何不同?
AQUALAST 1812(藍色)
根據美國官方 https://www.dupont.com/products/filmtecaqualast1812.html
FilmTec™ residential elements are one of the most effective, consistent and high-quality elements in the industry. Aqualast™ 1812 elements offer excellent anti-scaling performance allowing for high recovery operation without the need for custom pressure vessels or expensive encapsulated products. In high TDS applications, the Aqualast™ 1812 can outperform and have a longer life than conventional elements.
主要訴求應該是在高TDS的水質中....與傳統RO膜片相比較有更突出的性能與更長使用壽命
Advantages
High recovery that can lower the water bills for consumers(高回收率,幫助消費者節約水費)
Long life in high TDS/scaling applications(抗結垢,耐高TDS,使用壽命更長久)
NSF safety certification(獲NSF 安全認證)
Dry element for convenient handling and long shelf-life(乾膜,方便操作且保質期更長)
High quality elements significantly reduce or can eliminate element Quality Control (QC) costs
(高品質的元件大幅度降低甚至消除了針對膜元件的品質控制(QC)成本)
FilmTec™ TW30-1812-50HR
https://www.dupont.com/products/filmtectw30181250hr.html
FilmTec™ TW30-1812-50HR Residential RO Elements offer quick stabilization at high rejection and flow performance, and long effective lifetimes. Element performance is achieved by coupling FilmTec™ patented membrane flat sheet technology with efficient element designs that are less prone to flux loss due to scaling. Systems are enabled to produce reliable, high quality water with minimal system maintenance costs.
Advantages
Made in the USA by FilmTec, the worldwide leader in integrated membrane technology and element manufacturing, using the stringent 6-sigma system
Designed for professional purification needs, with a remarkable enhancement of 50% on salt rejection performance
To let you start the extraordinary purification journey quickly, the break-in time is significantly shortened to within 30 minutes
TapTec™ TT-1812-50
https://www.dupont.com/products/taptectt181250.html
TapTec™ TT-1812-50 Residential RO elements offer stable flowrate and good permeate quality to ensure safe and clean water for 50-gallon water purifiers with proven technology from DuPont Water Solutions. And it is NSF certified element.
Advantages
Proven technology from DuPont Water Solutions
More stable flowrate and good permeate quality
NSF certified element
Focus on the local needs in Asia
Value for money
根據上面所示,
AQUALAST 1812 應該是Dow 定位在家用高階產品
擁有的特點 抗結垢,耐高TDS,使用壽命更長久,高回收率...降低水費(也愛護水資源)
FilmTec™ TW30-1812-50HR 應該是取代舊系列產品,畢竟多了HR這兩個英文字
磨合期只需要30分鐘內...就可以迅速達到過濾效能


TapTec™ TT-1812-50 則是注重亞洲市場需求
以下是根據台灣經銷商(也是網路商家....你懂得)所提供的資訊
AQUALAST
是針對高硬度水質以及低廢水排放而設計,脫鹽率高達98%,
以原水TDS:300PPM、硬度160PPM水質條件,壓力70PSI,廢水排放1比1.2測試,
純水產量達20公噸以後還保有80%以上產水量,是款耐操又省水的RO膜
TF-50HR
以早期TF-50特性進階改良
以下是官方資料顯示
*****磨合時間*****
舊款 TF-50要運轉25小時之後才能達到95%以上的脫鹽率
新款 TF- 50HR只要30分鐘就能達到宣稱值99%脫鹽率
****脫鹽率*****
舊款TF-50 脫鹽率95%
新款TF-50HR 脫鹽率99%
*****產水量*****
同條件下產水量新款TF-50HR比舊款TF-50還多出5-10%

舊有的TF-50已在2019年全面停產
全面改TF-50HR規格,或是杜邦DUPONT泰湃科TAPTEC
陶氏化學、杜邦化學已全面合併
美國製造RO膜以FILMTEC品牌銷售
中國製造RO膜以TAPTEC品牌銷售
請大家別在搞混了
如果想要在高硬度水質、壽命長且更省水的...是可以選擇正宗美國製造的Filmtec AQUALAST 1812
想要過濾高效能,產水量更高的 可以選擇正宗美國製造的Filmtec TW30-1812-50HR
如果想要效能與價格取得一個最大平衡點,我是更推薦日本製造的膜片
