Ultra-pure Water System (Two-stage RO)

Name: Ultra-pure Water System (Two-stage RO)
Brand: Xinnian
SKU: XN-UPW/2RO

XN-UPW/2RO

The two-stage RO system takes first-pass permeate through a second RO pass for deep demineralisation, holding product conductivity below 1 μS/cm while removing bacteria, organics and residual ions. Automatic flushing, low-pressure protection and on-line water quality display make it ideal where high purity is required but EDI is not yet needed.

Key Features

Two RO passes in series, salt rejection ≥99 %, product conductivity ≤1 μS/cm
First-pass permeate feeds the second pass — high recovery and low concentrate discharge
Fully automatic with low-pressure protection, timed flushing and quality alarm
Modular design, can be upgraded later with EDI to a full ultra-pure system

Technical Data

Capacity	0.5 – 30 m³/h
Product conductivity	≤1 μS/cm
System salt rejection	≥99 %
Recovery	55 – 70 %
Feed water	Municipal water, pressure ≥0.15 MPa, turbidity <1 NTU
Control	PLC automatic, touch-screen HMI optional

Frequently asked questions

How do I choose the right capacity?

Send us raw water analysis (TDS, hardness, iron, silica), required permeate flow (m³/h) and target water quality. We size the membranes and pumps with a 10–15% design margin and return a P&ID with the quotation.

Can the system run on 380 V / 50 Hz or 440 V / 60 Hz?

Yes. Electrical design is built to your site standard — 220/380 V 50 Hz, 440 V 60 Hz or other voltages with local certification. Please state it when ordering.

Do you supply spare membranes and pre-treatment media later?

Yes, we keep membrane elements, filter cartridges and media in stock and ship spare parts within 7 days. A recommended spare parts list is issued with every system.
