A brief introduction to the key functions of each component module of the laboratory pure water system

      For the construction of laboratory pure water system, its components can not be ignored. In the planning of the pure water system planned by the modern laboratory, the more important is the pure water transportation and distribution pipeline system, which transports the high-quality pure water produced by the central pure water station to each of the an application address. The laboratory pure water system is composed of four core parts: pure water preparation module, pure water storage module, pure water distribution module, and monitoring equipment terminal purification module, each of which plays a key role in the successful implementation of the entire pure water system. .

(1) The key points of pure water preparation module:

1. System work intensity, operational stability and safety considerations;

2. Water quality requirements:

a. Application: Different applications have different requirements;

b. Standards: USP, EU, CLSI, ISO, GB, etc.;

c. Purification method and pure water technical grade selection;

3. Water demand:

a. Key indicators: daily water consumption;

b. Auxiliary indicators: peak water consumption, usage habits;

4. Water quality monitoring requirements:

a. Easy to use;

b. The measurement is accurate;

c. Fault warning and intelligent processing;

5. The cost concept of purchase and use:

a. Environmental needs or constraints.

(2) Key points of pure water storage module:

a. Water demand;

b. Peak water consumption;

c. Daily water consumption;

d. Liquid level control system;

e. Water quality requirements;

f. Material;

g. Germicidal UV lamps inside or outside the water tank;

h. Closed design;

i. Cleaning or disinfection strategies.
