What information is needed to purchase purified water equipment and water for injection equipment?

Purified water equipment and water for injection equipment are usually customized to precisely match the company's water needs. So, what information does the company need to provide when purchasing this equipment?

01

Water application

In short, what are the main applications of purified water and water for injection in the enterprise? The manufacturer will provide a suitable solution based on the enterprise's application.

02

Water quality standards

Does the water quality need to meet the standards of the Chinese Pharmacopoeia, the United States Pharmacopoeia, or the European Pharmacopoeia? Is it purified water for in-vitro diagnostic reagents? If there are any special requirements, please specify.

03

Certifications required for the equipment

The type of certification required for the equipment, including China GMP, US FDA, EU GMP, and 13485 certifications.

04

Raw water quality report

The raw water for preparing purified water usually comes from municipal tap water. The company needs to measure the conductivity and provide a tap water quality report. If the company cannot provide a water quality report, it can contact the water company to provide one.

05

Process selection

Requirements for the process, you can choose double RO, single-stage RO+EDI, and double-stage RO+EDI. In addition, for multi-effect distillers, the number of effects and the gas pressure of the pure steam generator need to be provided by the company. During system design, the manufacturer will use these basic data and process requirements to achieve water purification through a certain processing unit or combined operation. After advanced process technology treatment, the water quality is better.

06

Disinfection method selection

Usually, the preparation system needs to sterilize the activated carbon filter, RO membrane, and EDI device using pasteurization. It is necessary to understand whether the company has industrial steam. The distribution system disinfection methods can be ozone disinfection, pasteurization, hot water disinfection, and pure steam disinfection.

07

Basic project information

Equipment installation address, floor, floor load-bearing capacity, and water preparation room area. The manufacturer will design based on the basic situation of the enterprise project to ensure the normal and stable operation of the water equipment and improve space utilization.

08

Online detection instruments

Instruments for water quality detection, including SDI monitor, residual chlorine monitor, hardness monitor, TOC monitor; choose paperless recorder, paper recorder, or electronic signature.

09

Control system selection

Choose PLC automatic control, PLC+remote monitoring automatic control instruments, relay automatic control.

10

Distribution system situation

The height between the water preparation room and the highest water point, the total number of water points, the length of the circulation pipeline, the peak water flow and pressure, the normal water flow and pressure; the distribution system pipeline design requires a detailed layout diagram of the water points.
