Testing a Reverse Osmosis System With Your Own Water
Buyers should require a demonstration using their actual feed water, not a standard test supply, and define acceptance checks around permeate capacity and water quality before issuing an RFQ.
Ask the supplier to demonstrate the reverse osmosis system on a sample of your actual feed water rather than on a convenient test supply. Because the equipment is intended for filtration of water, feed composition can change how the system behaves, so a demonstration using your own material is more informative than a generic run.
In the RFQ, state the feed water source and ask what volume of sample the supplier needs for a trial. Request that the demonstration report the permeate flow against the catalog reference value of 1,000 L/h, and clarify whether that figure is nominal and under what feed conditions it was measured. Ask how permeate quality will be sampled and recorded during the trial, and whether the supplier will provide the test record.
For an acceptance test, agree in advance on the feed water to be used, the duration of the run, and how flow and quality readings will be taken. Confirm that the demonstration unit matches the offered configuration, and check the reference dimensions of 3,000 × 800 × 1,650 mm against your available space, treating them as catalog values rather than a guarantee for the supplied model.
Before requesting a quote, confirm with the supplier what feed water sample is required, how the demonstration will be witnessed and documented, and which conditions the stated capacity assumes.
