AI Technical Summary

Technical Problem

Traditional distributed membrane systems are difficult to clean offline due to limitations in site, surrounding environment, or working space. At the same time, the amount of cleaning agents used is large, and the transportation and maintenance costs are high.

Method used

Design a prefabricated offline membrane cleaning system, which uses a portable gantry and cleaning modules. The membrane stack is transported to the cleaning water tank for cleaning via the hoisting module. The cleaning machine and backwash solution storage tank are used to achieve cyclic cleaning, reducing the amount of chemicals used and maintaining stable system operation.

Benefits of technology

It enables rapid installation and dismantling, reduces maintenance costs and reagent usage, ensures uninterrupted system operation, and simplifies the disposal of cleaning waste liquid.
