Define this task first
Specify the actual factory or cultivation site location first
Even within the same city, specify the district or county, water abstraction point, and equipment installation location. Enter raw water information separately from the intended use, then check the process, configuration, and site conditions.
Does the water abstraction point match the sampling point in the test report?
Kunming water treatment equipment: clarify where the output water will be used first
Factory ingredient preparation, component cleaning, flower irrigation, and nutrient solution water preparation may have different requirements. First enter the points of use, required parameters, and their basis in the requirements form, then compare reverse osmosis, ultrafiltration, or softening. Calling equipment a pure-water unit does not make it suitable for every use.
Which documents to retain when comparing complete equipment quotations
List the models and quantities of pretreatment equipment, membrane modules, pumps, instruments, controls, storage, and water supply equipment. State feedwater conditions, permitted operating hours, and acceptance methods. List equipment prices, transport, unloading, piping connections, commissioning, and subsequent consumables separately. Resolve unconfirmed figures through technical discussions.
List requirements for soilless cultivation and flower growing separately
Water treatment consultations for soilless cultivation in Kunming need to distinguish raw water, treated water, nutrient solution, and return water. Provide sampling dates, EC, pH, and corresponding testing information. Equipment selection does not replace crop nutrition management. Water for growing flowers and postharvest handling of cut flowers should also be discussed separately.
Check equipment inlet and outlet piping separately from indoor water supply
For thin-wall stainless steel water pipe requirements in Kunming, first distinguish indoor water supply from water treatment equipment inlet and outlet piping. Inquiries about press-fit fittings in Kunming should list equipment connections, pipe diameters, wall thicknesses, material requirements, and quantities. Small-diameter plastic tubing on a water purifier cannot directly provide the specification basis for building water supply pipes. Even at sites in Kunming, the installation location and responsibilities need confirmation. Construction services are not included by default.
Compare quotations against the same operating conditions
Put the raw-water sampling point and date, feed-water temperature, target production and available daily operating hours on one sheet. Label laboratory results, site measurements and estimates separately. A membrane manufacturer's standard test output is not a project guarantee. If the proposal includes RO and EDI, list the RO outlet measurement point, the feed limits for the actual EDI model and its start/stop interlocks as separate items to confirm before comparing pretreatment, storage, instruments and handover documents included in each quotation.
Water preparation for blueberries and flowers in Kunming: identify the sampling points
For a blueberry, flower or other soilless-cultivation project in Kunming, identify the raw-water, treated-water, nutrient-solution and drainage sampling points first. Record EC units, temperature compensation, pH and alkalinity tests, and ask the grower to specify the crop, substrate and water-preparation targets. Separate water treatment, filtration, storage and fertigation control in the quotation; one EC reading cannot determine whether RO is needed.
Pipe and fitting integration information
Display of pipes, basic press-fit components, and threaded/flange adapters. Check specifications, connections, and supply responsibilities for the actual use.
Gudian Technology conducts the relevant business in Kunming, with remote discussions available for different regions. Supply, transportation, and site services are confirmed project by project. A general display does not indicate local stock, shops, or completed projects.
Information to bring to this discussion
The table below can serve as a checklist for this inquiry. Mark unavailable information "pending confirmation" and distinguish estimates from measured records. Do not upload identity documents, customer lists, or internal confidential materials.
| Discussion item | Information to prepare | Confirmation needed |
|---|---|---|
| Purchasing a new RO unit | Raw water report, output water use, and hourly and daily consumption | Corresponding model and acceptance conditions |
| Replacing membranes or filter cartridges | Old part model, dimensions, connections, and operating records | Manufacturer compatibility information and basis for replacement |
| Water preparation for flowers or nutrient solutions | Water sample source, crop, water preparation, and reuse arrangements | Responsibilities for treated water and nutrient management |
| Equipment connection adapters | Equipment port dimensions, thread or flange type, and design piping schedule | Matching product series for adapters and piping |
| Quotation comparison under matching conditions | Sampling date, feed temperature, target output, operating hours and equipment list | Whether quotations use matching conditions, and who confirms RO/EDI measurement points and interlocks |
Expand the general inquiry and delivery checklist
- 01Project location
- Prefecture or city, district or county, intake point, equipment installation location, and whether different locations are involved. Do not upload identity documents or customer lists for an initial inquiry.
- 02Water source and testing
- Tap water, well water, surface water, or other sources; record sampling points, dates, testing organizations, and the report's applicable scope. Do not infer water quality from a city name.
- 03Treated-water use
- Production, cleaning, cultivation, drip irrigation, or other uses; provide the corresponding process, crop, or actual usage requirements. Acceptance requirements may differ by use.
- 04Demand and schedule
- Daily demand, peak hourly demand, permitted operating time, and storage arrangements. Mark values for confirmation when measured data are unavailable. Estimates must not be recorded as equipment guarantees.
- 05Equipment and site
- Existing equipment models, consumable specifications, power supply, space, drainage, operating environment, and site-access conditions. Equipment photos should avoid capturing personal or confidential information.
- 06Budget and delivery
- Specify the budget, supply list, transportation, unloading, installation, commissioning, acceptance, and after-sales scope. Timing and expenses are governed by the confirmations for this project.
- 07Plateau site and water temperature
- Actual installation altitude, seasonal feed-water temperatures, pump inlet pressure or water level, suction piping and power; review the specific model. Altitude is not a water-quality test.
- 08Sampling points and operating baseline
- Sampling locations, dates, units, temperature compensation, and normal and abnormal records. Keep raw water, treated water, nutrient solution and return water separate.
