XLE2540
Membranes for industrial reverse osmosis systems

Dow Filmtec™ XLE-2540 is a high-performance reverse osmosis element with low energy consumption. Suitable for purification of water with medium level of mineralization. It provides high quality water at low operating costs.

The Dow Filmtec™ XLE-2540 membrane element operates at pressure minimal for reverse osmosis, by this reducing energy consumption.

Key features

  • Dow Filmtec™ membrane (USA) is the world standard for water purification
  • Clean water for business - 3 200 liters of water of stable quality per day
  • High energy efficiency due to low operating pressure
  • Large active surface of ​​the element provides higher productivity
  • Automated high-precision production makes it possible to obtain elements with maximum active surface

Technical data

  • Nominal active surface - 2.6 m²
  • Operating pressure - 6.9 bar
  • Permeate volume - 3.2 m³/day
  • Stabilized salt rejection - 99.0 %
  1. Permeate consumption and salt (NaCl) rejection are indicated for the following test conditions: 500 mg/L NaCl, 25°C and 15% permeate recovery.  
  2. Flow rates of permeate for every specific element might vary, but will not fluctuate by more than 15% from the indicated values.

Operating conditions

  • Maximum operating water temperature - 45 °С
  • Maximum operating pressure - 41 °С
  • Maximum pressure drop - 0.9 bar
  • pH range, operational mode - 2...11
  • pH range, chemical cleaning mode - 1...13
  • Maximum feed silt density index SDI < 5
  • Free chlorine tolerance - <0.1 mg/L

Maintenance

Before launch of the reverse osmosis system preliminary preparation of the membrane, refill of the elements, adjustment of the devices and other system checks should be performed.

Avoid any major pressure or flow surges inside the spiral-wound elements in the middle of launch, stop, cleaning etc. to avoid risk of damage infliction to the membrane. During the launch it is recommended to gradually switch the system from standstill to operational mode following the steps:

  • gradually increase feed water pressure during 30-60 seconds
  • operational rate of the flows should be developed gradually during 15-20 seconds
  • permeate obtained within the first hour of operation is discharged

Important information

  • After the initial soaking always keep the elements wet.
  • To prevent biofouling during long operation breaks it is recommended to submerge the membrane elements into preservative solutions.
  • Maximum pressure drop along the full length of the housing makes 2.1 bar.

What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
