1. Introduction Water is a precious resource for human survival and an indispensable raw and auxiliary material for pharmaceutical production. The quality of water used in the pharmaceutical industry, especially for pharmaceutical raw materials, directly affects pharmaceutical and drug safety. After many years of development, the purified water preparation process has evolved from a simple single plant to a complete set of purified water. The corresponding water-making process has also been greatly developed, from the simple manual development to the current centralized automatic control method. The following is a brief introduction to the preparation of purified water and the application of Delta's electromechanical products in water-making equipment.
2. Process and equipment introduction Under the natural conditions, the water continuously contacts the air, the surface, the bottom layer and the dissolution of the rock and the soil will contain various impurities. The main impurities can be divided into three categories: (1) sediments, animal and plant residues, microorganisms and other suspended matter; (2) colloids based on a collection of various molecules and ions; and (3) dissolved substances in the form of a single free molecule or ion.
Pharmaceutical water is process water that does not contain any additives. Systematic control of pharmaceutical water requires control of the levels of these impurities, while also effectively treating and controlling microbial and bacterial endotoxin contamination. Ionic resin exchange, distillation condensation, electrodialysis, reverse osmosis and other processes are usually used. The preparation process is roughly divided into five parts: pretreatment, primary demineralization device, deep demineralization device, post-treatment device, and pure water delivery and distribution system. The purified water equipment consists of a mechanical part and an electrical part: the mechanical part is mainly composed of a water pump, a pressure tank, a water tank, a solenoid valve, a filter and a pipeline; the electrical part is mainly composed of a programmable controller (PLC), a touch screen, a frequency converter, and a pressure gauge. , relays and other components. Figure 1 is a live demonstration of the preparation of purified water.
Control system hardware configuration: touch inverter, programmable controller (PLC), PLC extended analog module, inverter. The system is equipped with automatic and manual operation modes: automatic program control realizes automatic operation of the system through time relay timing calculation based on multi-point multi-channel water level sensor and dynamic pressure controller to monitor the operation of each component; manual operation is mainly used Used during system installation, commissioning and maintenance.

Conclusion With the development of science and technology, people's requirements for water quality (including medical water and drinking water) are also getting higher and higher. In order to obtain qualified purified water, the automation requirements for water treatment equipment are also increasing. The industry is expecting more new medicinal purified water equipment.
