Ammonia Drip Project

Pending NJDEP regulations will require that RVRSA control the level of trihalomethanes (THMs) in the plant effluent. THMs are a result of the chlorination process which disinfects the RVRSA effluent prior to being discharged into the Rockaway River, which is a public, potable, water supply.

Research has shown that by adding a controlled amount of ammonia to the plant effluent, THMs can be lowered to acceptable levels. Currently RVRSA is conducting a pilot demonstration project in which a controlled amount of ammonia is being added to the plant flow to reduce THMs. Laboratory analyses have shown very good results. Should this process be proven to continuously reduce THM levels, this would result in a huge savings to the Users of the RVRSA sewer system.
