Abstract:
Effluent-operated valves provide, in a septic system, distribution of effluent uniformly to a plurality of portions or fingers of a drain field. The installation of such valves in a tank that collects septic system effluent to be distributed to a plurality of fingers permits the uniform distribution of effluent from within the tank to a plurality of portions of a drain field, either simultaneously, or to one portion at a time in sequence.
Abstract:
A buoyancy flushing apparatus is disclosed which comprises a reservoir for accumulating liquid, having an inlet for receiving liquid and an outlet chamber recessed in a bottom wall of the reservoir. The outlet chamber includes an outlet for draining liquid out of the reservoir. The apparatus further comprises an outlet valve movable between a down position where liquid accumulates in the reservoir and a raised position where liquid accumulated in the reservoir is flushed out via the outlet. The outlet valve comprises a ballast unit sized and shaped to fit loosely in the outlet chamber when said valve is in the down position; and a float unit topping the ballast unit to move the valve in the raised position by buoyancy when a sufficient amount of liquid is accumulated in the reservoir, thereby providing a passageway for liquid between the bottom wall of the reservoir and the valve leading to the outlet in the outlet chamber to flush liquid out of the reservoir. Guiding means are provided for guiding the outlet valve between the down position and the raised position. The apparatus can be used for applications such as water treatment and irrigation. It could advantageously be used for directing and spreading waste water previously treated in a septic tank to different sanitary treating fields.
Abstract:
An accumulator for collecting a volume of a liquid, which includes controls to permit the liquid to rise in a container to a preset upper level, at which level a drain valve is opened causing liquid to flow out of the accumulator. The accumulator utilizes two opened bottom pipes, which are connected through check valves to a controller. The controller is sensitive to the pressure at its inlet port. The pipes are interconnected so that when the liquid reaches an upper level, the pressure at the controller is sufficient to open the drain valve, and once the accumulator is almost empty, the drain valve is closed.
Abstract:
The invention presented relates to a septic system which doses effluent into a disposal field. More particularly, the invention includes a relatively water-tight walled structure capable of accumulating a volume of septic tank effluent; a disposal field dosing system having at least one outlet conduit having an outlet end and an inlet end; a stand pipe which extends from each of the outlet conduits towards the top of the structure; a float having a chamber having an opening on an upper surface thereof; at least one feed conduit having an inlet end located within the chamber and an outlet end in operative connection with the inlet end of the outlet conduit; and a jointed coupler which forms the operative connection between the feed conduit(s) and outlet conduits.
Abstract:
This invention relates to apparatus for continuously discharging liquid from a container, such as a waste water tank having a discharge pipe with an inlet located adjacent the container floor and an outlet located outwardly of the container. The liquid flow is controlled by a control unit which operates as a function of the liquid level in the container. The discharge pipe has a riser section between its inlet and its outlet which extends upwardly to an apex section to define an overflow for the liquid. The riser section is adjustable in height which is controlled by control means that always maintains the overflow at a constant elevation below the liquid level in the container.
Abstract:
The invention relates to a tank (100) provided with at least one effluent-filling opening and at least two effluent-emptying openings, a bucket capable of tilting between a filling position, in which it can be filled with an incoming effluent through said at least one filling opening, and a discharge position, in which it can discharge the contents thereof through one or more of said emptying openings. According to the invention, the tank (100) includes means for modifying the position of the bucket (200, 200′) so as to change the direction thereof or to enable the replacement thereof with another bucket of a different type.It is thus possible to modify the effluent outlet direction by a simple change in the bucket position. It is also possible to replace a bucket with a bucket of a different type.In this way greater versatility of the adaptation to the connection of the tank on the installation site is afforded.
Abstract:
This invention pertains to a sequencer for controlling the distribution of fluid input into a tank to at least two outlets using a plurality of cells connected to actuate a respective floating outlet. Each of the cells has a relatively uniform construction comprising an enclosure and a float. Each enclosure has an inlet arranged at one end to allow fluid therein and offset openings at an opposite end. The enclosure also is configured to accept the float in an inner cavity and arranged so as to allow the fluid therein to cause said float to move within said enclosure. Each cell is further arranged in pairs of a lift cell and a trigger cell adapted to actuate a floating outlet. Each float has an inclined upper surface configured to transfer a ball through the offset openings as the fluid causes the float to rise and fall from each cycle of actuate a respective floating outlet. The sequencer being particularly adapted to a system and method for dosing a septic system having two or more disposal fields.

Abstract:
A flow control structure is provided for the selective control of a liquid flow from an external body of liquid or for liquid and/or solid separation. The flow control structure includes a container, a float, and a valve. The container has an inlet, an outlet, and a closed bottom surface. The float is buoyantly positioned within the container and rises and falls in response to the level of liquid in the container. A valve is positioned inside the container and is coupled to the float by a linkage so that the valve opens when the float rises above a preselected height and the valve closes when the float falls to the preselected height within the container. The length of the linkage between the valve and the float determines the height of liquid required to open the valve. The valve may be positioned at an angle relative to the horizontal.
Abstract:
An installation for the intermediate holding and storage of sewage and effluent, said installation comprising a sealable housing 9 having an inlet 1 for receiving said effluent and an outlet for discharging said effluent, a holding reservoir 2 pivotally mounted and positioned within said housing to receive and temporarily store a quantity of said effluent, wherein said holding reservoir is an asymmetrically shaped open bucket adapted to automatically move about said pivot from a first position adapted for receiving and storing said effluent to a second invented position where stored effluent is emptied into said housing under the influence of gravity once the accumulated effluent reaches a sufficient mass wherein said housing includes an effluent race 11 incorporated into the floor of said housing to divert said effluent directly to said outlet.
