More questions? Contact our engineers Frequently Asked Questions
What is the difference between RO and double-pass RO?+
Double-pass RO treats first-pass permeate again to reduce remaining dissolved solids where the confirmed quality target requires it.
When should I choose RO + EDI?+
RO + EDI is considered where the process requires continuous high-purity water and the water analysis supports an EDI polishing stage.
What information do you need for a proposal?+
Share a current feed-water analysis, target water quality, capacity, operating hours, site utilities and intended application.
Do you provide commissioning support?+
Commissioning can be scoped for installation review, start-up, operator familiarisation and agreed performance verification.

TECHNICAL GUIDEindustrial RO vs double pass RO vs RO EDIIndustrial RO vs Double-Pass RO vs RO + EDI: How to Choose the Right Pure Water System
Choose the treatment route from the required point-of-use water quality and the real feed-water analysis—not from a generic machine name. Single-pass RO is often an efficient starting point; double-pass RO adds a second desalting barrier; RO + EDI is used when a stable, low-conductivity polishing stage is required.

TECHNICAL GUIDEhow to size an industrial reverse osmosis systemHow to Size an Industrial Reverse Osmosis System: Capacity, Recovery, Pretreatment and Cost Inputs
Industrial RO sizing is a water-balance and risk-management exercise. Start with the point-of-use demand profile, then work backwards through storage, distribution, RO permeate flow, recovery, feed flow and pretreatment. A quoted m³/h figure is incomplete unless its temperature, feed-water quality and recovery assumptions are stated.

TECHNICAL GUIDEcontainerized pure water system overseas projectHow to Specify a Containerized Pure Water System for Overseas Factory Projects
A containerized pure water system is a delivery format, not a complete specification. It can reduce field assembly and simplify shipment coordination, but the process route, utilities, climate protection, access, lifting, installation interfaces and commissioning plan still need to be defined for the destination site.
