Gudian Technology · Yunnan project requirements information

Understand the water and its use first,
then confirm equipment and services.

Water-treatment selection in Yunnan starts with the actual source, intended use and site conditions. Based in Kunming, Gudian Technology can discuss industrial RO, soilless cultivation and fertigation, filtration and softening, consumables, and thin-wall stainless-steel piping remotely. Record project water temperatures, demand, tests and equipment interfaces; confirm supply, transport and site services individually. The following guides for Yunnan’s 16 prefecture-level areas help prepare enquiries and do not establish local outlets or completed projects.

Regional name reference Yunnan Provincial Department of Civil Affairs · Administrative Divisions ↗(The listed statistical tables are as of 2025-09-30; checked on 2026-10-06.) Administrative divisions organize the directory only. They do not replace actual addresses, water quality information, or confirmation of project commitments.

Find information by actual application

Start with the water use task

The following areas help prepare inquiries. Confirm specific processes and configurations from project information.

Production process water

Distinguish production, cleaning, and other points of use. Check inlet and outlet requirements, schedules, storage, and acceptance. Selection of reverse osmosis, ultrafiltration, or other processes requires corresponding information.

Factory requirements information →Reverse osmosis equipment information →

Water for cultivation and irrigation

Describe crops, raw water, nutrient solution, and reuse arrangements. Testing parameters must match applications. Equipment information does not replace a basis for nutrient management or growing results.

Soilless growing requirements information →Irrigation water equipment information →

Consumables and operating maintenance

Record equipment models, consumable dimensions, connections, alarms, and maintenance history. Confirm replacement intervals and cleaning conditions from specific product and operating information.

Membrane element information →Operation and maintenance guide →

Water supply and equipment piping integration

Thin-Wall Stainless Steel Water Pipes and Press-Fit Fittings

View display and inquiry 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 preparation / Six-item checklist

Give each discussion a documented basis

Knowledge and information →

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.

Step 1

Organize requirements remotely

Submit intended use, raw-water, demand, equipment, and location information. Clearly mark missing items.

Step 2

Check processes and provisions

Confirm feasibility using the relevant product documents, tests, and site conditions, and discuss the budget and necessary configuration.

Step 3

Confirm the site and delivery

Confirm transportation, installation, personnel, expenses, timing, acceptance, and maintenance responsibilities separately. Unconfirmed matters are not commitments.

FAQ

Can projects outside Kunming begin with a discussion?

Describe the actual location, intended use, and equipment needs remotely first. Supply, installation, and site-visit arrangements must be confirmed separately using this project's information. A service location or site visit cannot be guaranteed for every place.

Should I choose reverse osmosis, ultrafiltration, or softening equipment?

Compare using raw-water tests, treated-water uses, required criteria, demand, and operating conditions. Reverse osmosis, ultrafiltration, and softening perform different tasks. Regional or product names cannot replace specific equipment-selection evidence.

Can I inquire without a complete test report?

Describe known information and missing items first, then discuss what additional details are needed. Formal process, performance, and acceptance conclusions still require corresponding evidence. A preliminary discussion cannot be described as water-quality compliance or a promised result.

Are supply, installation, maintenance, and consumables included in the quote?

Check this project's quote and agreement item by item. Define equipment lists, transportation and unloading, site installation and commissioning, testing and acceptance, consumables, and after-sales scope. Do not assume every item is included in every project.

Can a regional directory prove that local project cases already exist?

No. Actual cases require project records, corresponding equipment, and publication authorization. Illustrations and regional names are not evidence of completed projects.

Does source water throughout the Yunnan plateau need the same treatment?

Neither “Yunnan” nor altitude establishes hardness, dissolved salts or contamination. Obtain project-specific water tests and use requirements, then distinguish particle filtration, softening, membrane desalination and other duties.
