Problems solved by technology

Due to the limitation of laboratory experiment conditions, it is impossible to use raw water to simulate some operating conditions in the actual project for continuous operation test and verification, often resulting in differences between engineering design parameters and actual operating data, and the results appear in the pretreatment process, membrane flux, etc. , The choice of membrane material and operation mode is unreasonable, resulting in a rapid decline in the performance of the membrane module, aggravated membrane pollution, making some engineering projects unable to operate normally, and causing major economic losses to the enterprise
