北京龍碧源美國陶氏膜一級代理8寸BW30HR-440i苦咸水膜
陶氏反滲透膜BW30HR-440i經(jīng)常用在大型水處理系統(tǒng)中，主要是用來去除水中的細菌、病原體、難降解的有機物等有害物質(zhì)。*的陶氏反滲透膜元件不但可以確保每個組件合理的設計，還不會出現(xiàn)污堵現(xiàn)象。同時還可以zui大限度的發(fā)揮增加膜的有效面積。下面介紹一下陶氏反滲透膜元件系統(tǒng)運行具體操作步驟：
北京龍碧源美國陶氏膜一級代理8寸BW30HR-440i系統(tǒng)運行具體操作步驟
1、在低壓力下將反滲透系統(tǒng)中的空氣趕出。
2、用低壓水將膜元件的保護液從滲透器沖出(開濃水排放閥)。
3、打開反滲透系統(tǒng)的濃水減壓閥。
4、高壓泵出口節(jié)流閥的開度調(diào)整到其初始壓力的50%。
5、啟動高壓泵進行沖洗，直至沖凈。
6、關斷反滲透設備的濃水排放閥，調(diào)節(jié)濃水減壓閥，調(diào)節(jié)給水泵出口節(jié)流閥，打開出口閥，關閉排放閥，直至達到設計的水流量和反滲透系統(tǒng)回收率。
7、做好反滲透系統(tǒng)的運行記錄包括試驗用儀器、藥品清單、試驗方法、預處理系統(tǒng)、原水加熱自動控制、凝聚燒杯試驗、加氯量試驗、出水濁度測定、SDI測定等。
The DOW FILMTEC? BW30HR-440i Reverse Osmosis Element is a high-performing, high-productivity element combining the highest active membrane area available in the industry today with the maximum rejection brackish water reverse osmosis (RO) membrane. It incorporates Dow's innovative BW30HR membrane sheet technology, designed to deliver the highest quality RO permeate. This is combined with the cleanability of a 28-mil feed spacer, to minimize capital expenses in high-purity industrial water applications, without increasing operating flux.
Used In:
Industrial water demineralization
Production of municipal drinking water
Water reuse
Advantages:
High rejection results in excellent water quality
Reduced downstream polishing required
Durable with good cleanability for long element life
FilmTec performance and quality
