Claim:
An interceptor configured to at least partially separate a mixture of a first material and a second material, the first material being a fluid, the interceptor comprising: a container having a base and a sidewall portion that extends upwardly from the base to at least partially define a separation chamber configured to receive the mixture and to facilitate separation of the first and second materials; an inlet aperture configured to provide fluid communication between the separation chamber and an inlet conduit that delivers the mixture to the interceptor; an inlet diffuser in fluid communication with the inlet aperture, the inlet diffuser including a body portion located within the separation chamber and an elongated outlet aperture that extends through the body portion to provide fluid communication between the inlet conduit and the separation chamber; and an inlet coupling that extends through the inlet aperture, the inlet coupling configured to couple the inlet conduit and the inlet diffuser, wherein the inlet coupling includes a threaded portion located within the separation chamber, the interceptor further comprising a locking collar coupled to the body portion and rotatable relative to the body portion to threadably engage with the threaded portion of the inlet coupling within the separation chamber to removably couple the inlet diffuser to the inlet coupling.
