美国DOW（陶氏）8寸BW30HR-440i苦咸水膜
陶氏反渗透膜BW30HR-440i经常用在大型水处理系统中，主要是用来去除水中的细菌、病原体、难降解的有机物等有害物质。*的陶氏反渗透膜元件不但可以确保每个组件合理的设计，还不会出现污堵现象。同时还可以zui大限度的发挥增加膜的有效面积。下面介绍一下陶氏反渗透膜元件系统运行具体操作步骤：
美国DOW（陶氏）8寸BW30HR-440i系统运行具体操作步骤
1、在低压力下将反渗透系统中的空气赶出。
2、用低压水将膜元件的保护液从渗透器冲出(开浓水排放阀)。
3、打开反渗透系统的浓水减压阀。
4、高压泵出口节流阀的开度调整到其初始压力的50%。
5、启动高压泵进行冲洗，直至冲净。
6、关断反渗透设备的浓水排放阀，调节浓水减压阀，调节给水泵出口节流阀，打开出口阀，关闭排放阀，直至达到设计的水流量和反渗透系统回收率。
7、做好反渗透系统的运行记录包括试验用仪器、药品清单、试验方法、预处理系统、原水加热自动控制、凝聚烧杯试验、加氯量试验、出水浊度测定、SDI测定等。
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
