Genesol 704 A general-purpose cleaner for a wide range of organic based foulants found in Reverse Osmosis and Nano-filtration membrane systems. Genesol 704 is particularly effective against aluminium silicate, which can be difficult to remove with conventional cleaners. It is also effective against most micro-organisms such as bacteria, fungi and algae. Genesol 704 should be used as a 1-2% solution at the maximum allowable pH recommended by the membrane manufacturer. It should be alternately soaked and recycled through the membrane system for 2-4 hours.
