SYSTEM SELECTION

What Information Is Needed to Size an RO System?

A practical feedwater, capacity, quality and site checklist for commercial and industrial reverse osmosis system enquiries.

Start with the water’s destination

A commercial or industrial reverse osmosis system is selected around a defined use and feedwater condition. Begin with what the treated water will do, the required flow and the quality limits supplied by the process or equipment owner. A rated flow alone does not define a complete system.

Prepare the feedwater information

Share a recent water analysis, source, sampling date and expected seasonal changes. TDS or conductivity helps characterize the water, but hardness, alkalinity, chlorine, suspended matter and other relevant constituents can affect pretreatment and operation. The assessment should reflect the actual source.

  • Water source, temperature range and available analysis
  • Existing pretreatment, chemicals and operating history
  • Required product-water quality and relevant acceptance method

State capacity with units and timing

Distinguish instantaneous flow, average use and daily production. Include the operating hours available to make that water and any storage or peak-demand requirement. State L/h, m³/h or US GPD explicitly so unit conversion does not change the request.

Include installation and delivery boundaries

Voltage, frequency, available pressure, drains, footprint and site access influence the configuration. Agree which tanks, pumps, controls, commissioning tasks and documents belong in the supply. Send the information already available; remaining questions can be worked through together.
