RO membrane elements

Selection guide

Start with the membrane family and feed water. Compare model-level test data, then verify the existing vessel, connection dimensions and required system duty. Send the current model and quantity for a replacement review.

RO membrane selection: compare the test conditions before replacing an element ↗

What to prepare

  • Feed-water source, salinity, temperature and analysis
  • Required permeate flow, quality and operating hours
  • Existing model, dimensions, connectors and pressure vessel
  • Element quantity, array layout and delivery destination
A matching model format or similar test flow does not establish interchangeability. Confirm mechanical fit and system performance before replacement.

From first brief to a defined scope

  1. Identify the water and membrane family
  2. Compare specifications and test conditions
  3. Check the installed element and vessel
  4. Confirm quantity and technical scope

Make the scope explicit

Ask the proposal to distinguish equipment supply, civil works, external piping, electrical connections, commissioning, training and consumables. Confirm each responsibility in the project quotation. Items discussed on this website are planning considerations, not an automatic inclusion in every supply package.
