How to Choose Reverse Osmosis Equipment: A Three-Step Guide to Source, Demand, and Intended Use
An approximately 51-second RO selection video explains the raw-water source, hourly peak demand, and treated-water use, with links to quotation, storage, and agricultural water-preparation information.

How to Choose Reverse Osmosis Equipment: Define Three Requirements First
When selecting reverse osmosis (RO) equipment, first specify the raw-water source, hourly peak demand, and treated-water use, then use the water-quality test report to confirm the target quality and process. Equipment photos and total daily demand alone are not complete grounds for equipment selection. This approximately 51-second video presents the order of pre-purchase discussions around these three items.
Pre-purchase information checklist
| What to provide | How to describe it | What it helps check |
|---|---|---|
| Water source and quality | Tap water, well water, or surface water; existing test reports, sampling times, and locations | Raw-water conditions and pretreatment needs; a regional name cannot establish water quality |
| Water demand and schedule | Daily usage, hourly peak demand, continuous or intermittent use, and existing storage conditions | How production, storage, and supply should be matched |
| Intended use and targets | Production, cleaning, or other uses; downstream equipment requirements and proposed acceptance criteria | Confirm the required water quality and corresponding treatment stages |
| Site conditions | Installation space, water and power supply, drainage, maintenance access, and existing equipment issues | Installation, operation, maintenance, and proposal scope |

| 00:00–00:04 | Buying reverse osmosis equipment | Prepare these 3 pieces of information first |
| 00:04–00:11 | 01 Where does your water come from? | Tap water / Well water / Surface water |
| 00:11–00:17 | 02 How much water do you need at peak times? | Hourly demand, not just the daily total |
| 00:17–00:25 | 03 Where will the treated water be used? | Define target water quality first |
| 00:25–00:32 | Consider the complete process | Do not rely on one equipment photo |
| 00:32–00:38 | Define the scope in the quote | Configuration / Operating conditions / Acceptance criteria |
| 00:38–00:50 | Send a private message with “水方案” (water plan) | Send: water source + demand + intended use |
Complete narration transcript
00:00 How do you choose reverse osmosis equipment? Start by making these three items clear.
00:04 First, where does the water come from? Tap water, well water, and surface water cannot simply use the same pretreatment.
00:11 Second, how much water do you need per hour at peak times? Do not report only the total daily usage.
00:17 Third, what will the water be used for? Production, cleaning, or another use? Define the target water quality first.
00:25 A proposal must consider pretreatment, reverse osmosis, and subsequent storage and supply together. Equipment photos alone are insufficient.
00:32 When requesting a quote, ask about the configuration, design operating conditions, and acceptance criteria together.
00:38 Need a water-treatment solution in Yunnan? Send a private message with “水方案” (water plan), along with your water source, demand, and intended use. Include a water-quality report if you have one. Yunnan Gudian understands Yunnan's water and understands high-altitude water treatment even better.
Clarify quotations and acceptance together
When discussing a quote, check the configuration scope of pretreatment, RO membrane treatment, and subsequent storage and supply. Include design operating conditions, target water quality, acceptance methods, and maintenance requirements in documents confirmed by both parties. Membrane type, feedwater conditions, temperature, and system design affect operating performance. Specific parameters must be based on the corresponding model and confirmed operating conditions.
Common selection questions
Can equipment be selected from daily water demand alone?
Also specify hourly peak demand, usage periods, and storage conditions. Even with the same daily total, concentrated and distributed usage may require different configurations.
Can equipment with the same “reverse osmosis” name be compared directly from photos?
Check raw water, target quality, the complete treatment stages, specific components, and design operating conditions. Photos only help explain the layout. They cannot prove production capacity, material grade, or acceptance results.
Can well water, tap water, and surface water use the same configuration?
Check the specific water-quality information and usage requirements first, then determine the treatment process. A water-source name alone cannot replace a test report.
What should I prepare for an inquiry with Gudian?
Provide the water source, demand, intended use, region, and any existing water-quality reports, along with site conditions and current issues. Yunnan Gudian Technology Research Institute is based in Kunming, Yunnan, and provides water-treatment solution design and equipment provision services. The specific service scope and implementation conditions are governed by documents confirmed by both parties.

After the video, continue looking up information by your question
The selection sequence in the video helps organize water source, demand, and intended use. For quotations, look up itemized comparisons; for peak demand, check storage arrangements; for agricultural water preparation, check raw-water and nutrient-solution measurement points. The linked articles provide supporting information. They are not additional narration or scenes in the video.
