An effluent processing apparatus comprises a housing having an inlet port and a chamber. A coalescing element is located in the chamber and arranged coaxially with the inlet port. The coalescing element has pleats in a predefined pattern of paths arranged to separate oil and water from an effluent mixture containing air, oil, and water. The effluent mixture flows into the inlet port along an axis of the coalescing element. The effluent mixture is deflected by a portion of the housing to flow perpendicular to the axis along major surfaces of the pleats to separate oil and water from the effluent mixture.

An oil sequestering, air-drying cartridge device comprises a pair of tandem fluid diodes for respectively preventing backflow of moist air into an oil coalescing filter and preventing backflow of dry air into a desiccant material. The device comprises an outer cartridge skin and a middle shell concentrically nested between the cartridge skin and an inner shell. The middle shell houses channel walls having offset wave-like contours that prevent backflow of moist air into the oil filter, and the inner shell comprises similar channel walls that prevent backflow of dry air into the desiccant, which is positioned between the inner and middle shells.

An effluent processing device includes an input port to receive an effluent mixture containing air, oil, and water. One or more baffles are positioned between the input port and at least one air outlet to deflect the effluent mixture to assist in separating the oil and the water from the air. A member positioned below the one or more baffles selectively allows only oil of the separated oil and water to pass from a first side of the member through openings in the member to a second side of the member. A sump is arranged to receive and retain the oil on the second side of the member as the oil passes from the first side to the second side. The effluent processing devices includes at least one air outlet through which air is exhausted to atmosphere.

An absorbent apparatus is provided for an air dryer purge air cleaner. The absorbent apparatus comprises a volume for containing absorbent material. The absorbent apparatus also comprises absorbent material that is both oleophilic and hydrophobic and is packed in the volume to provide a packed bed of absorbent material with a predetermined packing density. The packing of the material provides for a first and second flow path of an effluent stream through the absorbent material.

An effluent processing apparatus comprises a separator device arranged to receive an effluent mixture to separate oil and water from the effluent mixture and thereby to provide clean air. A member selectively allows either only oil or only water of the separated oil and water to pass from a first side of the member through openings in the member to a second side of the member. A sump is arranged to (i) receive and retain the oil on the first side if only water passes from the first side to the second side, and (ii) receive and retain the oil on the second side if only oil passes from the first side to the second side. Clean air from the separator device is exhausted through an air outlet to atmosphere, and water is drained through a water outlet to atmosphere.

The absorbent apparatus also comprises absorbent material that is both oleophilic and hydrophobic and is packed in the volume to provide a packed bed of absorbent material with a predetermined packing density.

An effluent processing apparatus is provided for a vehicle air brake charging system. The effluent processing apparatus comprises an inlet port through which effluent from a purge valve of an air dryer can be received and an outlet port. The effluent processing apparatus also comprises a spiral-shaped effluent channel having a portion of decreasing channel width disposed between the inlet port and the outlet port. The spiral-shaped effluent channel is provided for increasing velocity of an effluent stream as the effluent stream flows through the decreasing channel width portion of the spiral-shaped effluent channel.

An effluent processing apparatus is provided for a vehicle air brake charging system. The effluent processing apparatus has an inlet port through which effluent from a purge valve of an air dryer can be received and an outlet port. The effluent processing apparatus further has a quadric surface defining an effluent flow chamber that is connected in fluid communication between the inlet port and the outlet port. The quadric surface is provided for extracting contaminants from an effluent stream as the effluent stream flows from the inlet port along the quadric surface to the outlet port.
