A device to expedite removal of residual water-immiscible oil from a large tank through a manhole entry in the side of the tank, includes a trough which is inserted through the manhole and levelled, after which water fed into the tank floats the residual oil into the trough from which the oil discharges from the tank through the manhole for recovery or disposal.
Apparatus for recovery and reuse of parts cleaning fluid or similar fluid such as oil upon separation and removal from water, including a tank for receiving and collecting the water and fluid which floats atop the water. A removable shelf may be slidably mounted in the upper part of the tank for directing the fluid flow to the rear of the tank for channeled passage to a sludge collector. A box-like housing having a water discharge chamber partitioned by a plate-like baffle into water entry and outlet compartments which open to the upper part of the chamber that is vented to atmospheric pressure may be mounted in the lower part of the tank by associated fluid drain fittings. The outlet compartment has a drain whereas the water entry compartment has a relatively small inlet closely adjacent the bottom of the tank so that only water will flow into the water discharge chamber for automatic discharge from the tank upon the level thereof exceeding the height of the baffle. Also contained within the tank is a fluid reservoir which opens to the interior of the tank at a level higher than the height of the baffle for receipt and storage of fluid floating atop the water. A pump may be used to recycle the fluid, such fluid flowing through filters placed in the lower part of the reservoir and hoses terminating at a nozzle located above the tank. Also, a sight glass may be mounted in a side wall of the tank to permit visual observation of the respective fluid and water levels in the tank.
An oil removal device for separating floating oils from water or water-based liquids. A rotating disk lifts viscous oils frown the water or water-based liquid. The oil is removed from the disk by wiper blades on either side of the disk on the downward part of the disk's travel. The oil then falls into channels and is channeled into a storage container. A support frame comprising a base and a center post attached to the base is connected to and supports the disk, wiper blades and channels. A gravity separating chamber could be used in place of the storage container. Water collected by the disk is diverted from the oil by a small-scale gravity separator module. The gravity separator module includes a weir having a gap or space at the bottom to separate the water from the oil.
