What links cannot be ignored before the operation and commissioning of the laboratory pure water system?

      Laboratory pure water systems usually require the concentration of impurity elements and compounds in pure water to be at the ppb level or even lower. High performance liquid chromatography (HPLC) for trace analysis requires ultrapure water with low levels of organic contaminants as a mobile phase component. Typically, trace analysis requires that pure water be free of detectable substances and that any potential interfering substances must be separated from the water.

The laboratory pure water system is widely used in large and small laboratories, small chemical industry, electroplating, rhinestone industry, electronic cleaning, battery, battery cooling, medicine, food, beverage, paint, paint, cosmetics and other industries indispensable water treatment equipment. The system is simple, the piping is simple, only 3 main pipes (water inlet pipe, product water pipe and concentrated water pipe) are needed, no circulating pump and salt injection system, no PLC program controller, and low system construction cost and maintenance cost. The booster pump, solenoid valve, high-capacity ion exchange resin, R.O reverse osmosis membrane, filter element, pipeline connector, control element, ultraviolet lamp, etc. used in the equipment are all imported products.

In order to ensure the normal operation and debugging of the laboratory pure water system, it needs to be cleaned before operation. This link cannot be ignored. Let's talk about the correct cleaning methods.

① Before commissioning, the installed pure water conveying system must be tested for hydraulic pressure, and it can be carried out only after passing the test;

② Use 3% ~ 5% hydrogen peroxide to clean the pipeline for 40 minutes to achieve the purpose of disinfection and sterilization;

③ Use the pure water or reverse osmosis water supplied by the pure water station to flush the residual liquid medicine in the pipeline until the water quality at the point of use reaches the specified water quality requirements.

The above is the cleaning link before the operation and commissioning of the laboratory pure water system. I hope it can help you to better debug it.
