When selecting industrial reverse osmosis equipment, first establish the feedwater conditions, treated water use, actual demand and site conditions. Then determine the process and equipment configuration. Giving suppliers this information when requesting a quotation can reduce repeated clarification and make quotations easier to compare.
Start by describing the intended use
"Purified water for a factory" is not specific enough. Cleaning, solution preparation and process make-up water may have different requirements. Procurement staff can first confirm the parameters to control with the production department, process owner or downstream equipment supplier, together with their units, sampling locations and acceptance methods.
If downstream requirements have not been determined, document the information gaps first. Options can be discussed during an inquiry, but unconfirmed requirements should not be presented as final acceptance commitments.
Provide complete feedwater information
State whether the feedwater is municipal tap water, well water or another source, and provide recent water quality reports where possible. Include the sampling time and source with each report. Tell technical staff about any seasonal changes in the source. Different feed conditions may affect pretreatment and the main equipment configuration.
If no report is available, first list the intended use and volume, then discuss what test information is needed. Photographs, taste and water clarity cannot fully replace water quality data.
Separate daily volume from peak demand
Record daily volume, peak hourly demand, daily operating hours and storage conditions separately. For the stated hourly water production rate, also check the corresponding feedwater and operating conditions. A single daily consumption figure is generally insufficient to determine a complete system.
For example, concentrated daytime draw-off and distributed continuous use may require different storage and supply arrangements, even with similar daily totals. The specific configuration still requires technical calculations.
State delivery boundaries in the quotation
Confirm pretreatment, the main equipment, storage, water supply, piping, instruments, electrical controls, installation and commissioning as separate items. Some projects also involve connection to existing equipment, civil works or site piping modifications. The quotation should clearly state who is responsible for each activity.
Projects both within and outside the province require confirmation of transport, unloading, construction work, personnel and spare parts. State site services, timing and costs clearly for the project. Acceptance arrangements must comply with applicable mandatory requirements; an agreement between the parties cannot lower those requirements.
Discuss operating costs as well
In addition to the purchase price, electricity, water, consumables, maintenance and testing affect subsequent expenditure. Ask suppliers to state the assumptions behind their calculations. Compare quotations using the same feedwater, production targets, operating hours and cost scope. For projects with existing equipment, provide actual records where possible to avoid treating estimates as operating results.
Frequently asked questions
Can I request a quotation without a water quality report? You can first discuss the intended use, volume and approximate scope, but key conditions must be supplied before the configuration and formal quotation are finalized.
Are machines with the same water production rate equivalent? Not necessarily. Check the treated water targets, feed conditions, configuration, controls and service scope as well.
Is a more complex configuration always better? The configuration should serve clearly defined treatment targets and site requirements. Technical staff should explain the purpose of each stage.

Further calculations for hourly production and daily demand
Record effective water production time and production draw-off periods separately. Even with the same daily total, concentrated draw-off and continuous low-flow use may require different storage arrangements. The following resources provide calculations with stated assumptions and blank forms; they are not model-specific commitments.
