Equipment features
A. General
The equipment makes use of reverse osmosis membrane to produce purified water in compliamce with requirements of vaious pharmacopoeias across the world. Inclusive of pre-treament apparatus, heat exchange system, 1 pass RO purifiers and seterilization unit, it features easy operation, stable water output, desirable targets, and is widely used in the production of purified water.
B. Equipment properties
1. Output water quality : conform to standards from both China and European Union
Water system inspection targets

Note: under European pharmacopoeia regulation one is allowed to monitor either TOC or readily oxidizable substance only .
Finished water produced through our equipment comes with a conductivity less than 1.3 μS/cm.
2,System output capacity: 6 m3/h(based on water with a temperature of 20°C).
C. Raw water information:
1, Raw water : refer to water analysis report sent by end user.
2, Water consumption: water needed for operation more than 9.5m3/h, back-washing cycle around 2 hours.
3, Water feeding pressure: water from external source comes to raw water tank with pressure between 0.1~0.3Mpa. Users are required to place raw water pipe in the equipment range, and to insatll main feeding valve for easy control.
4,Power supply:
Air switch should be available to the water processing system, next to the
electric control box, requirements are as follows:
Power conditions: 220V/3ph/60Hz;
