纯化水系统Purified water system

纯化水系统作为GMP认证的关键系统，在整个认证过程中有着举足轻重的意义。二级反渗透、一级反渗透+EDI、二级反渗透+EDI的核心工艺已广泛用于药厂的纯化水制取。

纯化水设备：预处理系统（包括多介质过滤器、活性炭过滤器和软化器）、纯化水的制水系统：二级反渗透、一级反渗透+EDI、二级反渗透+EDI系统）、纯化水分配系统、巴氏消毒和CIP消毒系统及控制系统（全自动化控制系统和自动控制系统）组成。

设备采用PLC控制，触摸屏显示设备工艺流程、电导率、PH值、液位、流量流速，同时可以在触摸屏上实现手动和全自动操作。

在整套系统中一级、二级反渗透和EDI产水后设有不合格回流装置，当产水电导率符合设定值时产水进入下一道处理程序，不符合设定值时产水返回至前一道处理程序重新进行处理。当纯水箱满时设备会全自动进入小循环系统，确保产水运行无死角。

全套系统具有高、低压警报、水箱缺水警报、故障警报、压缩空气低警报、电导率不符合要求警报功能。三级控制系统、对产水电导率有储存功能并有USB打印机接口，从而实施全自动控制和操作。实现原水泵输送泵变频控制。还配有无纸记录仪、即时打印。

Purified water system as a key system for GMP certification, has important significance in the whole certification process. Two reverse osmosis, reverse osmosis + EDI, two reverse osmosis + EDIs core technology has been widely used in pharmaceutical purified water system to take.

Water purification equipment: pre-treatment system (including multi-media filters, activated carbon filters and softeners), purified water, water system: two reverse osmosis, reverse osmosis + EDI, two reverse osmosis + EDI system) purified water distribution system, pasteurized and CIP disinfection system and control system (fully automated control system and automatic control system).

The equipment adopts PLC control, touch screen display equipment process flow, conductivity, pH value, liquid level, flow velocity of flow, and manual and automatic operation on the touch screen.

Water production level in the entire system, two reverse osmosis and EDI has failed reflux device water production, water production into a treatment program when the conductivity of the water production line with settings, does not comply with the set value return handler before a re-processing. No dead ends when the pure water tank is full when the equipment will be fully automated to enter the small-circulation system, to ensure that the operation of the water production.

Complete system with a high and low pressure alarm, water tank alarm, fault alarm, compressed air, low alarm, the conductivity does not meet the requirements of the alarm function. Three control systems, the conductivity of the water production, storage and USB printer interface, so that the implementation of automatic control and operation. Pump raw water pump frequency conversion control. Paperless recorder comes with instant print.
