Title: Improved oil/grit interceptor
Inventor: WILKINSON JAMES
IPC: E03F5/14
Filed: 1997-09-24
Abstract: An interceptor tank for primary treatment of rainwater runoff which may contain a variety of pollutants. The tank is a multi-chambered device which provides a partial separation of the pollutants contained in the effluent rainwater. A bypass system prevents overload of the tank during periods of heavy inflow conditions. Under low inlet flow conditions, an orifice in the bypass system functions to allow the effluent to drop into the first chamber which serves as a trash and debris collector. The effluent passes from the first chamber to a second chamber where free petroleum based products are separated and held. The effluent from the second chamber passes into a third chamber where sediment is separated from the effluent. Here particles having a specific gravity greater than water are permitted to settle and are held for later recovery. The effluent from the third chamber may be fed back into the bypass conduit to be fed into a sewer system or alternately through an aperture in one of the exterior walls of the last chamber to a sewer.      Under heavy inflow conditions the level of the effluent stream raises, only a portion of the effluent may enter the first chamber (as controlled by the size of the orifice), the balance of the input stream passes over the orifice and into the last chamber of the tank or directly into the sewer system (if the bypass system continues through the third chamber).

Title: Particle separation and detection apparatus
Inventor: HARLEY PHILIP
IPC: G01N21/53
Filed: 1997-01-07
Abstract: Particle detecting apparatus for detecting oil mist or other particulate matter comprises a measuring section (5) and an input/output section (6) which are removably attached together. A measuring chamber (60) receives gaseous fluid by diffusion from a receiving chamber (30) connected via an inlet (16) to an area being monitored. The measuring chamber (60) is defined by a cylindrical body (34) housing pairs of light emitting diodes (46A, 46B...) positioned diametrically opposite each other and directing light towards each other through a sampling volume (62) which is viewed by a photo-diode (52) through a viewing aperture (56). The photo-diode (52) detects light scattered by particles in the sampling volume (62). A glass tube (64) protects the LEDs (46A, 46B) from contamination and can easily be cleaned or removed and replaced. Each of the LEDs (e.g. 46A) can temporarily be de-energised in turn so as to act as a light detector, its output in response to light received from the opposite LED (e.g. 46B) being thus a measure of any contamination.  The measuring and input/output sections (5, 6) can easily be separated for servicing or replacement.
