  陶氏反渗透膜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
