Reverse Osmosis membrane elements can experience a decline in performance due to the accumulation of deposits
on the membrane surface. Mineral scale, colloidal particles, biological matter, and insoluble organic compounds are the
usual causes of membrane fouling. When production of a Reverse Osmosis system drops by at least 10 percent, or the
differential pressure increases by 15 percent (over normal operating conditions), membrane cleaning should be performed
Acid and Caustic cleaning chemicals are most commonly used for membrane cleaning. Acid cleaners are designed to
remove inorganic and iron deposits. Acid (low pH) cleaning should be performed at a pH of about 2. Caustic (high pH)
cleaners are designed for removal of biological matter, organic foulants, and silica deposits. Caustic cleaning is performed at a
pH of about 12.
The cleaning system is designed to be used with any RO system to clean membrane withou removing membrane form
the system. A chemical storage tank is mounted on its own stand and connected to the skid with either hard piping or quick
disconnect fittings and flexible hoses. This gives the unit the ability to be mounted in a permanent location as a CIP (Clean In
Place) or portable if desired.
