High Pressure Spiral Membrane Elements

Why use high pressure spiral elements?

High TDS Feeds

As environmental regulations tighten, end users are being pushed to treat as many streams as possible, including high TDS feed streams. Since standard membrane elements historically can only tolerate up to 41 bar (600 psi) operation, membrane manufacturers have had to develop elements capable of handling high pressure operation to overcome the osmotic pressure of these high TDS streams. Applications examples for high TDS streams are MLD and ZLD.

Solution: High Pressure Membrane Elements

Using specialty membranes created especially for high-pressure situations is the ideal solution. TRISEP® High Pressure (HPR) elements have a maximum operation pressure of 83 bar (1,200 psi) while TRISEP Ultra-High Pressure (UPR) elements can go up to 120 bar (1,740 psi) to overcome high osmotic pressure. These elements are available with RO or NF membrane for monovalent/divalent separation and use durable materials of construction.
