Define this task first
Check production requirements against actual operating hours
Enter daily consumption, peak hourly demand, permitted operating hours, and backup arrangements. Confirm nominal production against the corresponding equipment's feedwater conditions, actual requirements, and storage proposal.
How will water use be managed during shutdowns or maintenance?
How daily consumption becomes a design input
Gather requirements for working days and other operating periods, separating continuous use from brief peaks. Dividing the daily total by operating hours provides only a starting point. Actual design must also consider storage, permitted equipment conditions, maintenance shutdowns, and feedwater changes. That calculation cannot directly guarantee a main unit specification.
Where will water come from during maintenance shutdowns?
Confirm whether operations can pause, how long existing storage can supply water, whether a verified backup source exists, and whether its water meets the intended use. Discuss backup arrangements separately from equipment prices. Adding a tank does not automatically solve every continuous supply requirement.
Acceptance records need more than one total water quantity
Agree sampling and measurement conditions. Record flow, time, pressure, inlet and outlet parameters, and the instrument basis. Check unit production, storage use, and supply at points of use separately. Do not replace complete equipment performance acceptance with storage tank level changes alone.
Specify every connection end dimension even for small replenishment orders
Even small thin-wall stainless steel water pipe requirements in Zhaotong should record pipe length, wall thickness, and connection end specifications. When replenishing press-fit fittings in Zhaotong, specify each end's dimensions for straight couplings, reducers, or elbows. Confirm quantity, packaging, transport, and receiving checks separately. Local stock or fixed arrival times are not promised.
Separate shutdown impact from cost per unit of product water
Use acceptable product-water volume, electricity readings, raw-water volume and chemical and consumable records from the same accounting period, noting starts, stops and cleaning downtime. Record concentrate, backwash water and cleaning waste destinations separately; not all water used by the equipment is product water. Describe backup supply and shutdown impacts separately. Avoid changing the denominator or omitting cost items to produce an incomparable cost per unit of water, and keep estimates separate from actual expenditure.
RO-output planning in Zhaotong: record operating hours and water temperature
Equal daily demand can require different arrangements for continuous production and concentrated withdrawals. List shifts, peak hourly demand, available treatment time and usable storage, then provide seasonal water temperatures and membrane-system documents. Keep design conditions, estimates and measured records separate, and compare costs under the same demand and operating conditions.
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 |
|---|---|---|
| Demand periods | Daily and hourly quantities, sustained peaks, and shifts | Permitted operating hours and actual requirements |
| Backup arrangements | Shutdown plan, storage, and backup sources | Whether they meet the intended use during maintenance |
| Acceptance data | Measurement times, instruments, operating conditions, and sampling | Production and supply verification under the same conditions |
| Replenishment quantities | Individual item names, specifications at each end, lengths and quantities, and receiving location | Supply models, packaging, and lead times |
| Cost ledger for a common period | Acceptable product water, electricity, raw water, chemicals, consumables and downtime | Accounting basis, concentrate destination, and whether backup-supply costs are separate |
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.
