Product Description

We provide turn-key solution for your pharamceutical water system project. From technical design to machine production, shipping, installation and training.
No. | Unit | Parameter information |
1 | Name | Molecular 3000L/H PW System |
2 | Model | MOLPW-3000L |
3 | Permeate capacity | 3000L/H@ 25℃ |
4 | Feed water | Tap water |
5 | Pure water quality | Electrical Conductivity <1.3μs/cm,meet GMP, EP/USP |
6 | Technology | double stages reverse osmosis unit+EDI unit |
7 | Control method | Automatic Control (manually also available) |

Our pharmaceutical water systems integrate cutting-edge Reverse Osmosis (RO) and Electrodeionization (EDI) technology to consistently produce ultra-pure water that exceeds pharmacopoeia requirements with a built-in safety margin.
Equipped with a PLC+HMI control system, the equipment features both automatic and manual operation modes with comprehensive real-time monitoring. Continuous water quality while intelligent algorithms optimize operational parameters to maximize efficiency and minimize downtime.


The modular construction simplifies installation, maintenance, and future capacity expansion. All water-contact components are manufactured from pharmaceutical-grade stainless steel or UPVC, featuring sloped piping and a dead-leg-free design to prevent microbial growth.
Comprehensive safety features include multiple alarm systems, self-diagnostic functions, pressure relief valves, high/low-level protection, and abnormal water quality alerts. This redundant protection architecture ensures continuous safe operation and protects your critical pharmaceutical processes from contamination risks.


Smart operational optimization reduces energy consumption by up to 30% compared to conventional systems. The EDI module lowers operational costs while minimizing environmental impact. Durable core components offer extended service life with minimal maintenance requirements.



A: A typical PW system usually includes pretreatment (multimedia filtration, activated carbon, softener), reverse osmosis (RO), electrodeionization (EDI), storage, and distribution loop with constant circulation and UV / ozone sanitization.
Q: Why is EDI commonly used instead of mixed bed ion exchange in modern PW systems?
A: EDI avoids chemical regeneration, reduces chemical contamination risk, ensures stable water quality, and is more compliant with GMP requirements for continuous and reliable production.
Q: What key quality parameters must be monitored for purified water in pharmaceuticals?
A: Key parameters include conductivity, TOC, microbiological count, endotoxins (if for WFI preparation), pH, hardness, and heavy metals, in accordance with pharmacopeial standards such as USP, EP, or ChP.
Q: What is the difference between Purified Water (PW) and Water for Injection (WFI)?
A: PW is produced by RO/EDI and used for non-parenteral products. WFI has stricter limits for endotoxins and microbes, usually produced by distillation or multiple-effect evaporation from purified water.
Q: How to control microbial growth in the purified water distribution loop?
A: Maintain continuous circulation at a certain flow rate, control loop temperature (hot water sanitization), regularly sanitize with heat or chemical agents, install UV sterilizers, and avoid dead legs.
