Selection Guide

To specify the correct purification skid, evaluate these parameters from your water analysis report:

Total Dissolved Solids (TDS)

Determines if single-pass or double-pass RO is required.

Silt Density Index (SDI)

If SDI is over 3, ultrafiltration pre-treatment is needed to prevent membrane fouling.

Total Hardness

Determines softener sizing and chemical dosing capacity.

Required Flow Rate

Ensures pump size and membrane area match operational demands.

Manufacturing and Quality Control

Welding Certification

Process piping welded by technicians certified to ASME Section IX standards using TIG methods with argon purge.

Pressure Testing

Hydrostatic pressure testing performed on all pressure vessels and piping skids at 1.5 times maximum operating pressure before dispatch.

Factory Testing

Each skid undergoes a 4-hour dry and wet functional test to verify pumps, valves, electrical interlocks, and alarms.

FAQ

Q: What raw water parameters are needed for system sizing?

A: A complete water analysis report including TDS, pH, hardness, silica, iron, manganese, free chlorine, and SDI is required to run membrane projection software and size pre-treatment accurately.

Q: What is the typical recovery rate for an industrial RO system?

A: Standard single-pass industrial RO systems operate at 75 to 80 percent recovery. Systems with concentrate recycling can exceed 85 percent recovery, depending on raw water conditions.

Q: How is membrane fouling managed during operation?

A: Systems feature automated low-pressure flushing at startup and shutdown. Clean-In-Place skids with integrated chemical tanks are also included for periodic chemical cleaning.

Q: What standards do your control panels meet?

A: Control panels are built to UL or IEC standards using industrial components housed in NEMA or IP-rated enclosures.

Q: What documentation is supplied with the equipment?

A: Each shipment includes drawings, electrical schematics, component manuals, material certificates, hydro-test reports, PLC backup, and recommended spare parts lists.

Q: What is the standard lead time for a custom skid?

A: Standard catalog configurations ship in 6 to 8 weeks. Custom multi-stage skids with specialized metallurgy require 10 to 14 weeks, including factory testing and documentation.
