Abstract:
The formation of scale in a reverse osmosis membrane apparatus is reduced at low water temperatures without the necessity of pH adjustment or addition of a scale dispersant to continue a consistent operation for a long period of time. The operation of a reverse osmosis membrane apparatus is controlled on the basis of the concentration of aluminum ions and/or iron ions in the feed to the reverse osmosis membrane apparatus and/or the concentrate from the reverse osmosis membrane apparatus. Not only silica but also aluminum ions and iron ions that are also present in the water significantly affect the reduction in the flux of a reverse osmosis membrane which is caused by silica scale. It is necessary to appropriately control the concentration of aluminum ions and/or iron ions in the feed and/or the concentrate to consistently operate a reverse osmosis membrane apparatus for a long period of time.

Claim (Index 13):
The reverse osmosis membrane treatment system according to  claim 10 , further comprising a unit that measures the concentration of silica in the feed and/or the concentrate, wherein the control unit controls the items on the basis of the concentration of aluminum ions and/or iron ions and the concentration of silica.
