.~> For concentrate entrained in effluent gas outlet means {1}
DEFINITION
Classification: 55/338
(under the class definition) Apparatus having means to direct system fluid which has passed through a stage of separation back through or substantially through the inlet to the apparatus or back through a distinct stage of serially arranged separators.
(1) Note. Redirecting system fluid substantially back to the inlet is meant to include both internal and external arrangements of flow means wherein the redirected fluid enters upstream of the first apparatus part which influences the separating action.
(2) Note. Recycle apparatus may never lose control of the system fluid; e.g., effluent may not be discharged to the atmosphere and then sucked back again.
(3) Note. For these subclasses system fluid may be the partially or totally cleansed effluent, or may be the gas which has escaped to the concentrate or residue chamber.
