  • Patent number: 8915380
    Abstract: A separator 252 for immiscible liquids comprises a tank having an inlet, a separation chamber and an outlet chamber 262, with the inlet 12 feeding effluent into the separation chamber 28 at or below a maximum acceptable flow rate. The effluent is separated into a more dense and less dense fractions in the separation chamber 28. The separation chamber 28 is in communication with the outlet chamber 262, where the more dense fraction exits. An outlet 260 for the less dense fraction is in communication with the separation chamber 28 and has a lowermost exit level at which the less dense fluid exits. The more dense fluid cannot rise to the level of the lowermost level, and the height of the less dense fluid is such that it will exit through the outlet as the more dense fluid passes over the weir.

  • Patent number: 8900463
    Abstract: A separator for separating oils from waste water and solids. Waste liquids are drained into a baffle tube of the separator so that the oils rise and the waste water and solids migrate to the bottom of the separator. A collection head having a restriction is located at the bottom of the separator and is adapted for suctioning the waste water and the solids therein and carrying the same to a discharge outlet of the separator. Waste liquids drained into the separator provide the hydraulic force to accelerate the waste water and solids into the collection head. Liquids drained into the separator also provide the hydraulic force that allows the oils to be drained from the top of the separator.

  • Publication number: 20080149553
    Abstract: A separator provides improvements for better separation of an effluent into constituent parts and greater ease of use. A tapered basket provides improved flow and better filtration. A baffle directs effluent into the basket with greater force. An asymmetrical flange prevents mis-orientation the basket and baffle. An improved oil valve provides a locking mechanism to prevent dislodging of the valve during cleaning. An alternative valve uses a sensor to sense an oil/water interface and close the oil valve appropriately. A top seal prevents leakage of effluent at connection points with the lid of the housing. An underground unit allows below floor level installation of the separator. A bidirectional unit can be reversed to provide flow in either direction. A dual purpose tank can be used to store both separated oil and oil from operations for common removal.
