  • Core processPretreatment + double-pass RO
  • Product-water targetConfirmed from application and applicable standard
  • RO desalination>=99.5% overall reference under suitable conditions
  • Frame and vessels304 or 316L stainless steel by project
  • Sanitary optionsTank, recirculation loop, UV, ozone or heat sanitization
  • ControlPLC, conductivity monitoring, alarms and quality divert

Final water quality depends on the complete generation, storage and distribution design, not the RO skid alone.

PROCESS FLOW

Purified-water generation and distribution route

The complete route protects water quality from raw-water pretreatment through generation, storage and every use point. Optional polishing and sanitization stages are selected only from the project standard and risk assessment.

  • Raw-water tank, pump and project-specific pretreatment
  • Precision filtration and antiscalant or softening where required
  • First-pass RO and intermediate tank
  • Second-pass RO with online conductivity monitoring
  • Optional EDI, UV, ozone or terminal filtration
  • Sanitary product-water tank with protected vent
  • Recirculation pump and sanitary distribution loop
  • PLC controls, alarms, interlocks and quality divert
Stainless steel purified water equipment process flow
Reference route only. Pretreatment, polishing, storage and loop details are confirmed from feed analysis and the applicable quality target.
WATER TREATMENT PRINCIPLE

Purified water is more than an RO outlet

Two membrane passes reduce dissolved salts and stabilize conductivity, but the required water quality must remain protected after generation.

Tank venting, drainability, dead-leg control, circulation velocity, surface finish, sanitization and monitoring all affect the quality delivered at the use point.

The system is not automatically suitable for Water for Injection. WFI and other critical applications require their own applicable production, storage, distribution and validation review.

WHY THIS ROUTE

Practical selection advantages

  • Double-pass RO for a lower and more stable conductivity target
  • Stainless construction for controlled production areas
  • Sanitary tank, distribution and sanitization options
  • Generation and downstream loop engineered as one project boundary

BUYER QUESTIONS

Purified-water questions before quotation

These checks define whether the skid, sanitary storage and loop are matched to the same quality target.

Is every stainless RO system purified-water equipment?

No. The water-quality target, storage, distribution, sanitization and monitoring strategy must all match the application.

Should 304 or 316L stainless steel be used?

The material grade depends on the applicable standard, cleaning chemistry, chloride exposure, surface-finish requirement and buyer specification.

Can a sanitary storage tank and circulation loop be included?

Yes. Send the tank volume, loop length, use-point count, return flow, operating temperature and sanitization method.

Is purified water the same as Water for Injection?

No. WFI has separate production, storage, distribution and validation requirements. Confirm the applicable standard before equipment selection.
