Mechanical / hydraulic

The element shell is made of FRP (Fiber Reinforced Plastic).

Dimensions

• Each membrane element is supplied with one interconnector (coupler) and four O-rings.
• All RE2540 elements fit nominal 2.5 inch (63.5 mm) I.D. pressure vessels.

General Handling Procedures

• Elements contained in the boxes must be kept dry at room temperature (7–32°C; 40–95°F) and should not be stored in direct sunlight.
• For WET-TYPE, a preservative solution (1% sodium metabisulfite solution) is added to prohibit the growth of micro-organisms.
• Permeate from the first hour of operation should be discarded.
• Stabilized salt rejection is generally achieved within 1~48 hours of continuous use.
• Keep elements moist at all times after initial wetting.
• Avoid excessive pressure and flow spikes.
• Only use chemicals compatible with the membrane elements and components. Use of such chemicals may void the element limited warranty.
• Permeate pressure must always be equal to or less than the feed/concentrate pressure. Damage caused by permeate back pressure voids the element limited warranty.
• Be aware of glass fiber strands from the FRP shell and use safety equipment.
