Abstract: A closed, cross-flow fluid filter assembly having a pressurized input line for polluted fluids entering into a closed header box. The closed header box fits within a filter tank and is provided with apertures and spacer assemblies on the bottom wall thereof communicating with the filter tank, the apertures providing the pressurized fluid thereto. Filter leaf assemblies are arranged in parallel within the filter tank and are maintained at their top edges in spaced relation by the spacer assemblies. The filter leaf assemblies are composed of abutting offset grids, contained within a fluid tight frame which is covered on each side by a filter media. The filter leafs are drained of filtrate through a medial tube connected to a central manifold which is connected to a vacuum source. Flow-through backwash stop-grids are arranged in the filter tank to prevent excessive bulging of the filter membranes during backwash for cleaning of the filter media. The filter media are also cleansed by the shearing effect of the pressurized input fluid flowing over filter media faces. Unfiltered fluid passes out of the filter tank at the bottom thereof. The filter assembly is designed in modular fashion with quickly releasible parts for ease of maintenance and flexibility.

Abstract: A filtration system is provided for a dry well in the form of a buffer tank made of concrete to remove sediment and pollutants from water supplied from a header to an inlet pipe in the tank, so that the water exiting from an outlet pipe is free of particulate matter and pollutants. This is accomplished by providing a sediment pit and a baffle at the inlet side of the tank and then passing the water through a multiple stage set of filters having different aperture sizes. These filters remove particles and pollutants from the water as it passes through the buffer tank on its way to a dry well drain pipe attached to the outlet of the buffer tank.

Abstract: In order to clean a screen in a waste water purification plant a surge of a body of water is generated by the agency of a dump flushing apparatus, which surge drops in a free fall towards the screen to be cleaned. This surge of cleaning water is given a dimensional extent which ensures for a substantially simultaneous impinging of the body of water onto the total extent of the screen. A framing which surrounds the screen encompasses this surge of water such as to guide the water and to force the water to flow through the screen. During the cleaning or flushing action the contaminants adhering to the screen, which contaminants are substantially of a thixotropic nature, will be removed from the screen and flushed through a sump towards the water purification section of the water purification plant.

Abstract: 552,302. Filters. PATERSON ENGINEERING CO., Ltd., and SMALLEY, W. Oct. 24, 1941, No. 13709. [Class 46] In a filter having a sand &c. bed a and a spillover wall b to prevent wastage of sand during cleansing by a reverse flow of wash water, the wall b is provided just above the bed a with one or more apertures d adapted to be opened and closed by means of one or more rollers or pads e operated by toggle lever or other mechanism to permit removal of the silt-laden waste water remaining above the bed after the sand has settled. The rollers or pads may be covered with rubber or like material. The impurities may be prevented from settling and washed through the apertures d by the continued application of wash water at a reduced rate, assisted, if desired, by a cross current of water. As shown, rubbercovered pads e of channel form are carried by pivoted arms g and operated by toggle lever mechanism h connected through link and lever mechanism k, l and bevel or screw-gear with a hand wheel i or a small electric motor under push button control. Alternatively, the rod k may be operated by a solenoid. Rollers may be adapted to be rolled over the surface of the wall b. The opening and closing of the apertures may be effected automatically in dependence on the rate of flow of wash water as by connecting the wash water inlet to a lightly-loaded diaphragm or other valve controlling the flow of pressure fluid to and from a cylinder having a piston connected with the pads &c. The rise in pressure of the wash water may also be utilized to close the electric circuit. Specifications 293,534, [Class 46], and 403,523 are referred to.
