摘要:
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.

The invention relates to apparatus for the detection of particles and for particle analysis. The apparatus comprises a sample holder comprising a base and a projection extending from the base. The base includes a contact region where, in use, the surface of a fluid sample may contact the projection. The surface of at least the contact region of the projection exhibits properties that allow the surface of the contact region to be substantially wetted by a fluid sample when the apparatus is in use so that the fluid sample forms a meniscus having its apex in contact with the contact region of the projection. The invention also relates to methods for using the apparatus.

A method is provided for detecting, measuring or controlling particles and/or electromagnetic radiation, comprising providing a deformable material containing a deformable aperture defining a path for particles or radiation, adjusting the deformable aperture to a prescribed geometry and/or size by deforming the deformable material to change at least one of the parameters of the path defined by the deformable aperture, and causing the particle or radiation to be detected, measured or controlled to enter the deformable aperture. The method includes the step of monitoring the geometry and/or size of the deformable aperture and controlling the adjustment of the size of the deformable aperture in response to such monitoring. The required apparatus is easily fabricated from inexpensive materials. Furthermore the deformable aperture can be tuned to the appropriate geometry post fabrication, and the ability to adjust the aperture geometry renders it capable of discriminating a plurality of differently sized particles.

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.

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.
