Abstract
PURPOSE: To enhance chroline-treatment efficiency by keeping the activity of available chlorine in water by using a chemical composed of hydantoin or its derivative.
CONSTITUTION: A chlorine activity maintainer composed primarily of hydantoin or its derivative, e.g., 5,5-dimethylhydantoin, etc., of the formula (where R1 and R2 are, respectively, H, an alkali metal, or a halogen and R3 and R4 are, respectively, H or l to 12 carbon alkyl group) is mixed with a chlorine agent or added to a water to be treated containing a chlorine agent in a proportion of 0.5 moles in terms of available chlorine. In this case, the R1 and R2 radicals, as shown in formula of hydantoin compound used are replaced with chlorines and stabilized, thus permitting the release of chlorines according to the need. Thus, the activity of chlorine present in water to be treated can be made durable, assuring the maintenance of its oxidation, sterilization, and bleaching action for long time.
