RO and EDI compatibility requires more than permeate conductivity. Check feedwater limits for the actual EDI model, sampling points, permission to energize, fault interlocks and operating records. Do not transfer another model’s flow or purity figures.
Read the guideFor domestic, commercial or centralized supplies, identify the intended use, applicable drinking-water standard, sampling point, test parameters and report scope. A TDS or conductivity reading alone cannot establish drinking-water safety.
Read the guideCheck current standard versions for press-fit fittings, thin-wall pipe and O-ring seals separately. Confirm material, dimensions, tools and test documents for each actual model; photographs cannot establish specifications.
Read the guideFor water-treatment pumps in Yunnan, record the actual location, minimum water level, temperatures, suction layout and duty. Assess NPSH against the selected pump curve; a city or prefecture name cannot establish altitude or pump performance.
Read the guideDistinguish experimental methods, model feed solutions and test scale from purchasable NF element data. Use research to frame questions about selectivity, fouling and maintenance; do not copy paper results into equipment specifications.
Read the guideWater-monitoring and machine-learning research in 2026 emphasizes data, validation over time and operating roles. These references do not establish automatic equipment control by Gudian’s content workspace or its installed equipment.
