JM ENVERTO oil/water separator

NEVER any need to change « a filter NEVER any downtime for backwashing

MARLAND, the recognized name in marine sanitation devices also offers an oil/water separator, INVERTO.

Meets or exceeds ail current regulations. INVERTO meets or exceeds all U.S.C.G. and IMCO regulations tor discharge of oil. INVERTO produces an effluent well below the IS pptn concentration required by IMCO

Resolution A.393 (X) (MARPOL). In actual tests, an effluent as low as 3 pprri oil was produced with a near 100% oil influent concentration.

Self-Cleaning... non-clogging. INVERTO will reverse its flow periodically to provide continuous, non- clogging operation. The self-cleaning feature means no filter changing... no costs for consumables.

Low-pressure system. INVERTO operates at less than 15 psi. The system is always tilled with liquid. Its operation is independent of the ship's movement.

Three stage operation. The first stage separates large slugs of oil by .virtue of the oil's lower specific gravity.

The second stage further coalesces the oil by use of a backwashable fluidized bed. The third stage removes the last residue of oil with a patented finger construction plate separator.

Sizes to fit most every requirement. INVERTO is available in six basic models, with capacities from 1.0 to 5.0 tons per hour.
