Scale prevention method and magnesium hydroxide scale inhibitor for reverse osmosis membrane |
| abstract |
In a reverse osmosis membrane treatment, a scale prevention method and a magnesium hydroxide scale inhibitor for reverse osmosis membrane capable of suppressing the production of magnesium hydroxide scale without significantly increasing the phosphorus concentration in waste water. To provide. A copolymer having a weight average molecular weight of 1,000 to 50,000 obtained by polymerizing a monomer component containing (meth) acrylic acid and 2- (meth) acrylamide-2-methylpropanesulfonic acid is reversed. Add to the osmosis membrane treated water system to suppress the formation of magnesium hydroxide scale in reverse osmosis membrane treatment. [Selection figure] None |
