Find the cause before replacing the membrane
Replacing a membrane whose performance has fallen does not solve the problem, it only postpones it. The same pretreatment, the same operating conditions and the same chemical regime will bring a new membrane to the same point before long.
That is why we treat membrane replacement not as a standalone consumable job but as part of a system analysis: trends in differential pressure, conductivity and flow usually point clearly to the cause of the damage.
