ABSTRACTA new chloramine agent, 3‐chloio‐4, 4‐dimethyl‐2‐oxazolidinone, has been tested in a laboratory scale water treatment plant as to its efficacy in water disinfection. The agent seems to be equally effective as compared to chlorine gas in this application. The results of preliminary toxicity studies on the agent are very encouraging. The agent has a long shelf life both in water solution and in the solid state. Being a solid, the agent is clearly less hazardous to handle than chlorine gas. The agent appears to inhibit oxidative corrosion of metals as well. The agent is less likely to produce toxic halocarbons (e.g., chloroform) in water than is chlorine gas. Possibly most important from the standpoint of water disinfection, the agent is a “slow release” one for its positive chlorine, which provides prolonged bacteric
