SCALE PREVENTING AGENT INCLUDING PHOSPHORUS AND METHOD OF PRODUCING THE SAME

摘要

The present invention relates to a reverse osmosis membrane scale preventing agent including phosphorous, and a method for producing the same. In particular, 2-acrylamido-2-methylpropansulfonic acid other than acrylic acid is mixed and used as a monomer of a polymer for preventing scale. Sodium hypophosphite is used as a chain transfer agent. Not only calcium scale preventing effects but also other scale preventing effects are excellent, and a more quantity of reverse osmosis water can be produced during the result unit time. Operation costs such as washing costs or membrane replacing costs can be saved. In addition, an ammonia compound is excluded, so occurrence of green tide or red tide can be fundamentally blocked.
