연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

An apparatus and system for mixing and separating ozonated water is provided. The apparatus is especially useful as a component of a system for cycling sanitizing ozonated water to a body of water such as a pool, spa or pond. The apparatus generally includes a separating vessel including a mixing tower, preferably located substantially entirely within the separating vessel and including a diffuser element for enhancing mixing of ozonated water without increasing turbulence in the separating vessel. Preferably, the apparatus includes a seal mechanism that substantially prevents liquid water from escaping the separating vessel with vented off-gas. The invention further provides an ozone destruct assembly including a condensate collection portion, and may also include a return line for passing a treated off-gas into the body of water.
