    Abstract: The waste water treatment system comprises a waste water treatment facility having an inlet for the entry of waste water and an outlet, and a re-circulation tank including an inlet and an outlet. The inlet of the waste water treatment facility is in fluid communication with the outlet of the re-circulation tank. The system includes a distribution chamber including an upstanding wall, a floor, an inlet, and at least two outlets conduits. A first outlet conduit is in fluid communication with the re-circulation tank; and a second outlet conduit is in fluid communication with a discharge conduit. At least one flow distribution chamber outlet conduit typically includes an inlet opening which is disposed at the same vertical height as the floor of the distribution chamber to allow the entry of waste water which has entered into the distribution chamber, such that substantially no waste water entering into the distribution chamber through the inlet will be retained within the chamber. Each flow distribution chamber outlet conduit typically comprises a pipe having a wall, a portion of which is vertically disposed within the distribution chamber. The vertical disposed portion of the pipe wall typically further includes a plurality of vertically spaced inlet openings passing through the wall. Each outlet conduit pipe typically passes through the floor. The flow distribution chamber may further include more than one outlet conduit in fluid communication with the re-circulation tank. The distribution chamber includes a re-circulation manifold disposed beneath the floor to collect the flows from the outlet conduits. The waste water treatment facility is typically a sand filter which includes flow distribution pipes have orifices. The present invention includes orifice shields for preventing the filter media from entering into the orifices of the flow distribution pipes. The orifice shields include both flat and concave orifice covers to disperse the water which sprays out of the flow distribution pipes orifices.

    Abstract: A strainer for use with a dry hydrant having a fluid inlet includes an inlet tube having a first end and a second end, the first end being substantially capped, and the second end being connected to the dry hydrant fluid inlet. A plurality of apertures are formed in the inlet tube and are disposed between the first end and the second end. The apertures are disposed in a substantially v-shaped pattern, whereby an apex of the substantially v-shaped pattern is spaced proximal to the second end. In one embodiment of the present invention, the apertures spaced proximal to the first end of the inlet member have diameters greater than diameters of the apertures spaced proximal to the second end of the inlet member. In operation in a dry hydrant system, the strainer provides for uniform suction zone throughout the inlet pipe, and provides uniform fluid drafting flow.

    Abstract: A two stage rotary pulp screening device has two screens in line within a single chamber. The accepts from the second screen can be recirculated to the primary screen as an integral part of the device. The improvement comprises a second screen within the chamber, downstream and co-axial with the primary screen and having a diameter at least as large as the primary screen, the impeller extends axially in a downstream direction within the second screen and has a body shape with a circular axial cross section whose diameter increases from the outlet end of the primary screen in the downstream direction, second impeller blades radiating from a downstream portion of the impeller for the length of the second screen, and second pulp stock discharge outlet from exterior of the second screen.

    Abstract: A filtering apparatus suitable for being cleaned by backwashing includes an outer housing (11) and an inner filter (13) disposed in the outer housing defining an outer annular flow passage (16) and an inner flow passage (17). The outer housing is tapered in relation to the external shape of the filter to provide a substantially uniform liquid velocity through the filter in both forward flow and backflow directions. The filter is made up of a plurality of ring-like segments (38) stacked end to end on which a filter medium (37) is mounted.

    Abstract: An intake distributor for a settling tank filter with horizontally arranged filter elements which are located one above the other on a vertical hollow shaft arranged centrally in the tank while at the upper end of the inner tank chamber there is provided an annular chamber which is coaxial with the axis of the tank. This annular chamber on one hand communicates with the inlet and, on the other hand, through a coaxial annular slot or gap communicates with the interior of the tank. A suspension comprising a carrier liquid and a filter substance or an auxiliary filter means is passed through the annular chamber or annular slot in the interior of the tank, and the filter substance or auxiliary filter means while being circulated is settled on the filter elements. The inlet to the annular chamber is divided into at least two branches which lead at equal angular distances into the annular chamber. The flow cross section of the annular slot is considerably less than the flow cross section of the inlet. In the inner tank chamber outside the annular slot there are provided deflector members for the suspension leaving through the annular gap which deflector members serve for reducing the energy and speed of the flow.
