Successful membrane cleaning depends primarily on the nature of the foulant. Before selecting cleaning chemicals and designing a cleaning protocol it is vitally important to correctly identify the deposit or foulant trough a RO feed water proper lab analysis and membrane autopsy service.
For the most effective cleaning, and therefore reduced cleaning frequency, conditions of pH, temperature and contact time are important.
We've provided the information below for guidance; however we would recommend asking us to design a cleaning protocol for you.
