Three useful buying questions
What determines the capacity?
Review daily use, peak withdrawals, operating hours and storage together. Model capacities are nominal; two RO passes work in series and their outputs are not added together.
Is concentrate recovery included?
It is a separate project decision, not an automatic part of two-pass RO. Identify recovery equipment and return-water arrangements separately in the supply list.
Why can quotes for the same RO capacity differ?
The same nominal output may cover different pretreatment, RO stages, storage, distribution and site work. Compare the agreed supply lists and water-quality requirements; adding EDI is a separate design decision, not a standard inclusion. See the EDI technology reference.
