QUICK TECHNICAL ANSWER
What is an industrial ultrapure water system?
KONCHE Ultra-Pure Water Systems: the four-system family for high-purity duties — 18.2 MΩ·cm resistivity, TOC ≤0.5 μg/L, 0.5–100 m³/h — configured to each end use.
How KONCHE scopes an ultrapure project
- Each project is reviewed against the water-quality specification, feed analysis, flow profile and factory utilities before the process train is fixed.
- Reference values on this page apply to stated conditions; final materials, instruments and performance guarantees are confirmed after engineering review of the complete system, loop and use points.

PRODUCT DOCUMENTATION
KONCHE provides a coordinated range of industrial ultrapure water, EDI, pharmaceutical purified-water and deionized-water systems. Each project is configured from feed-water analysis, required flow, final resistivity or conductivity, TOC and microbial targets, distribution conditions and the applicable industry standard.
Product documentation
An industrial ultrapure water system is a staged purification and polishing plant that produces water to a project-specific target. Resistivity, conductivity, TOC, particles and microbes are specified per end use. Electronic-grade KONCHE plants combine pretreatment, RO, EDI, 185 nm TOC UV, membrane degassing, polishing resin and terminal filtration. Documented reference values reach 18.2 MΩ·cm resistivity with TOC ≤0.5 μg/L across a 0.5–100 m³/h capacity range. Semiconductor, PCB and display fabrication set the strictest requirements. The correct process train depends on the end use: electronics, pharmaceuticals and general industrial deionized water do not share one universal specification. The page table compares EDI, mixed-bed, pharmaceutical and deionized variants by resistivity, TOC and capacity. Polishing stages are selected against the destination standard, feed-water analysis and distribution-loop design rather than resistivity alone.
02
How it is used
Pretreated water passes through RO, then EDI or polishing resin, UV and a terminal filter. Water quality is monitored and consumables are replaced routinely.
03
Where it fits
Semiconductors and electronics, biopharmaceutical production, precision analysis, pharmaceutical processes, research and fine chemicals.
04
Effectiveness
Under suitable conditions, product-water resistivity can reach 18.2 MΩ·cm. Poorer feed water or exhausted consumables can lower final-water quality.
05
Energy consumption
Typical complete-system electricity use is about 1–2 kWh/m³. Exact demand varies with feed water, pressure and the selected process train.
06
Cost
Costs include the equipment purchase, polishing resin, cartridges, UV lamps and servicing. Poorer feed water usually shortens consumable replacement intervals.

FAQ
How do I choose between EDI and a mixed bed?
EDI supports continuous deionization without routine acid-and-caustic regeneration and is normally selected for long-term high-purity production. A mixed bed can reduce initial investment but requires chemical regeneration and waste handling.
Is 18.2 MΩ·cm required for every industrial process?
No. The target should follow the actual process. Some boiler, chemical and rinsing applications need 1–15 MΩ·cm, while critical electronic processes may require 18.2 MΩ·cm plus TOC, particle and microbial limits.
Is the polishing mixed bed mandatory after EDI?
Not always. It is selected when the final resistivity, TOC, silica, continuity or risk-control requirement justifies an additional polishing barrier.
