What is the typical replacement cycle for membranes, and what is the cost of replacing membranes for a capacity of 300,000 tons?
Based on the operation conditions of the cell, it is generally replaced every three to four years. For over four years, no matter how well the ion exchange membrane performs! The seal gasket of the battery tank has also reached the end of its useful life; when leakage occurs, it must be replaced, as safety cannot be taken lightly!
