1. OBJECTIVE
The objective of the Clean In Place (CIP) system is to is to introduce high pH and
low pH membrane cleaners to the AmeriWater MRO system at low pressure and
high velocity. This action removes scale and organic contaminants from the
MRO membranes and improves system performance.
2. CHEMICALS REQUIRED
AmeriClean A (P/N 37-0004) low pH cleaner for removing inorganic scale and
metals from polyamide thin-film composite (3 lb (800 ml) of AmeriClean A powder
is required per membrane cleaning). AmeriClean A effectively removes the
following foulants:
•
Calcium Carbonate

Strontium Sulfate
•
Calcium Sulfate

Iron
•
Barium Sulfate

Metal Oxides
AmeriClean B (P/N 37-0005) high pH cleaner for removing acid insoluble
foulants from polyamide thin-film composite (3 lb (1,110 ml) of AmeriClean B
powder is required per membrane cleaning). AmeriClean B effectively removes
the following foulants:
•
Silt

Microbiological
•
Colloids

Acid Insolubles
•
Organics

Mucilaginous Material
WARNING: Wear appropriate eye and skin protection when handling the
membrane cleaning chemicals. The cleaners are high pH and low
pH chemicals that may cause severe chemical burns. Read the
MSDS for further information.
WARNING: Never allow AmeriClean A and AmeriClean B to mix! Mixing the
chemicals will cause an exothermic reaction which may result in
serious injury and/or damage to the equipment! Flush the system
thoroughly and verify that the pH of the reject water is neutral prior to
introducing another chemical!
WARNING: AmeriClean A and B membrane cleaners are for polyamide thin-film
membranes only and cannot be used on cellulose acetate
membranes.
