CLEANER ALKALI FOAMER LIQUID 205L

PermaClean PC-77 is a membrane cleaner specifically designed to remove iron fouling. It also is
effective against light calcium carbonate scaling. The efficacy of PermaClean PC-77 can be
enhanced by the addition of PermaClean PC-33 to the cleaning solution although some minor pH
correction may be necessary.
PermaClean PC-77 should always be used as recommended by the membrane manufacturer or
equipment supplier, in respect to cleaning pH and temperature.
