National Day launch | Gudian Technology's official website is now live
The official website of Gudian Technology (云南古滇科技研究院) launched during the National Day holiday. Explore equipment, consumables, industry solutions, and knowledge resources, and discuss your actual water requirements with us.
View detailsRural Centralized Water-Supply Handover: Recording Sampling, Abnormalities, and Outstanding Tasks
Prepare a working record for centralized water-supply purchasing and operational handover. Distinguish information sources, sampling locations, abnormalities, actions taken, and outstanding tasks. The sheet is not proof of water-quality compliance or project acceptance.
View detailsFlower Growing, Postharvest Handling, and Water for Preservative Solutions: Responsibilities Across Three Stages
Hypothetical examples of two types of needs within a growing operation distinguish water preparation for flower growing, postharvest solution preparation, and purchasing finished preservatives, with a table for water quantities, measurement points, and delivery responsibilities.
View detailsSource-water testing for soilless cultivation: what EC, pH and alkalinity tell you
Distinguish raw-water, treated-water preparation, nutrient-solution, and return-solution measurement points. Standardize EC units and temperature records, and use ion, pH, and alkalinity information together to assess whether RO should be discussed.
View detailsMatching Factory RO Production and Storage: Calculate Daily Demand and Hourly Peaks Separately
Two hypothetical examples with the same daily total but different usage schedules explain the relationship between industrial RO production, usable storage, and point-of-use peaks. Equipment selection still requires actual operating conditions.
View detailsHow to calculate industrial RO water cost per tonne: six cost items beyond the purchase price
Calculate RO operating costs using expenses from the same period and usable water measured at the same point. Define the scope of raw water, electricity, consumables, testing, and capital expenditure, with arithmetic examples clearly labeled as fictional.

What to check when scale appears
Scale can be a clue for investigation. Altitude or a place name alone cannot establish water hardness.

Reviewing water quality documents for centralized rural supply
Check samples, dates, sampling locations, and applicable requirements. Clarity, taste, or TDS cannot replace the required testing.
