Circulating water
Thread Content
I would like to ask everyone for advice. Who has the indicators for circulating water in chemical plants? ； What precautions should be taken if the circulating water system is shut down for an extended period of time?
The relevant indicators can be found by searching on Baidu. If the circulating water is not in use for an extended period, impurities and microorganisms in the system will increase to excessive levels, and the membranes on the inner walls of the system may become ineffective. Before restarting the system, it is necessary to clean it, replace the fluids, and pre-condition the membranes
Refer to GB50050; additionally, it is necessary to shut down the system for how long? If it is shut down for more than 24 hours before restarting, it is recommended to drain the water and clean the pre-coating layer again
