RO Membrane Element Performance Test Equipment

■ Overview
The RO Membrane Element Performance Test Equipment (also called membrane separation evaluation device) is a testing bench integrated by Beijing Wanyiyuan for reverse osmosis (RO) and nanofiltration (NF) membrane elements. With a multi-channel parallel piping design, it tests one or more elements on-line at the same time, collecting real-time permeate flow, salt rejection and operating pressure to support selection, acceptance, performance evaluation and diagnosis.

■ Structure and control
The unit integrates flowmeters, pressure gauges, control valves and a PLC + touchscreen control system for intuitive operation and traceable data. The main frame uses stainless steel/corrosion-resistant piping in a compact, stable layout.

■ Features
1. On-line testing: real-time permeate performance and salt rejection for various RO and NF elements
2. Multi-channel parallel: multiple independent channels test several elements at once
3. Precise measurement: flowmeters, pressure gauges and regulating valves for stable, accurate results
4. Smart control: PLC + touchscreen HMI for simple operation, data display and recording
5. Robust build: stainless steel/corrosion-resistant piping on a compact skid, easy maintenance
6. Fully customizable: tailored to membrane size, channel number, parameters and automation level

■ Applications
Factory inspection for membrane manufacturers; incoming acceptance for projects; membrane selection for system design; performance and cleaning-recovery assessment for in-service elements; experiments for research institutes and universities; technical evaluation for integrators.
