Abstract: A kitchen sink installation includes a plurality of adjacent kitchen sinks having drain tailpieces, a manifold pipe mounted substantially horizontally under the sinks and having a length and a plurality of discrete openings along its length, each of the openings facing upward in alignment with and spaced by an air gap from one of the sink drain tailpieces, and an outlet at one end of the manifold pipe adapted to connect to a downstream flow direction of sink effluent.

Abstract: A food disposal system for installation on a drain of a commercial kitchen sink enables segregation of oil/grease from effluent flows from the drain. A housing collects effluent flows containing water, oil/grease, and solids from the drain, and a macerating pump has an inlet connected to an opening of the housing that is other than downwardly directed and an outlet connected to a sanitary drain. A greasy water outlet extends to an oil/grease separator from an outlet on the housing above the macerating pump inlet, and a hot water backflush source enables hot water to flow into the housing.

Abstract: An assembly for connection to the drain of a cooking appliance which diverts low volume flow effluent from the drain is disclosed. The assembly includes a pipe defining a main flow channel. An auxiliary exit port is connected to the pipe in such a way that the low volume flow will be diverted from the pipe into the auxiliary exit port. A hot water entry pipe port is also connected to the pipe and is in connection with a hot water source which provides a flow of hot water into the pipe. Additionally, a solenoid valve regulates the flow of hot water into the pipe.

Abstract: An apparatus for separating an immiscible or insoluble fluid mixture into its components, namely, a less-dense component and a denser component, is described. The apparatus may be used in commercial kitchens to separate grease-oil/water mixtures into a grease-oil component and a gray water component, the grease-oil being diverted to a receptacle for subsequent disposal and the gray water component being directed to a drain or sewer. The apparatus may be described as a pump/separator when attached to a vacuum source or a pump to assist with filling. Additionally, a compressed gas source may be attached to the apparatus to assist with the discharge of the denser component and the less dense component. The apparatus may include a controller, such as a microprocessor, to coordinate filling, separation, and discharge. Parallel and serial arrangements of the apparatus are shown.

Abstract: An apparatus for the separation of immiscible liquids from liquid influent has a containment vessel. An influent channel extends toward the bottom of the vessel so the influent is discharged vertically upward, a downwardly curved deflection plate is mounted above and aligned with the discharge end of the influent channel, and a plate with a downward slope from a central location extends toward the periphery of the vessel in a lower portion of the vessel than the deflection plate. This permits the influent to move radially outwardly thus slowing the influent and providing a residence time for gravitational separation of lighter immiscible liquids from the influent. A gap between the downward slope plate and the discharge end of the influent channel permits gravitational release of trapped immiscible liquids. A transfer tube, a sensor, and a pump are provided to pump the separated immiscible liquids out to a remote location.

Additionally, a solenoid valve regulates the flow of hot water into said pipe.

Abstract: A collection apparatus for the collection and disposal of effluent from multiple sinks is provided that effectively maintains air gap and sanitation requirements within a minimal vertical distance. The preferred embodiment of present invention has multiple sinks with downwardly disposed drains and a trough mounted to collect the effluent flow from the drains. The trough has a discharge end, an overflow end, and a generally rounded bottom extending beneath the sinks and upwardly open to effluent discharging from the drains. The trough is mounted to induce effluent flow to the discharge end of the trough. The effluent flows from the sink drain through flow diverters located on the drains toward the discharge end of the trough through an air gap and into the trough. The air gap is provided between the lower end of the flow diverter and the bottom of the trough. The effluent is discharged from the trough through the discharge end into a grease separator.

Abstract: A method and apparatus for separating grease from solids and water in a sewage lift station, and separately transferring said grease, and said solids and water, from said station to remote higher destinations, comprising conveying grease from a first chamber to an adjacent second chamber at a first given level, and pumping solids and water from the first chamber from below the first given level to a third chamber; conveying water from the second chamber to the third chamber at a second given level no higher than the first given level, and pumping grease from the second chamber at the second given level to a first, remote, higher destination; and pumping water and solids from the third chamber at below the second given level to a second, remote, higher destination.

Abstract: An apparatus for pumping liquids to a destination includes a pipe of a first cross-sectional area extending from the liquid to be pumped to the destination. A body having a cross-sectional area less than twice the first cross-sectional area also has an upper portion, a lower portion, an inlet in the upper portion and an outlet to the pipe in the lower portion, a gas injection port, and a normally open valve between the gas injection port and the inlet, closeable upon an injection of gas through the gas injection port. Gas injection apparatus injects gas through the gas injection port from time to time. When no gas is being injected, liquid may enter the upper portion of the body through the inlet and fall by gravity toward the outlet in the lower portion and the pipe. Upon injection of gas, the valve closes, trapping liquid in the body below the valve, and trapped liquid is forced out the outlet and into the pipe toward the destination.

Abstract: Grease is separated from a mixture of grease and water in a grease collection tank having first and second access ports by skimming the grease from the mixture with a skimmer, and pumping the grease with a pump located in the first access port from the skimmer through a conduit to a storage container located in the second access port.

Abstract: An apparatus for removing grease from a grease trap separator containing grease and water and transferring the grease to a remote location includes an enclosed transfer tank, a first transport tube having an inlet end positioned to contact the grease in the grease trap separator and an outlet end extending into the tank, a second transport tube having an inlet end positioned to contact the water in the grease trap separator and an outlet end extending to the tank, a transport means arranged to convey the water through the second transport tube between the tank and the grease trap separator, a discharge pipe extending from the tank to a remote location, a first sensor for determining when the tank is filled with grease, and a second sensor for determining when the tank is filled with water, the first and second sensors controlling the action of the transport means.

Abstract: An oil/grease separation apparatus includes a chamber for receiving a liquid flow containing water, oil/grease and gross solids. An inlet section is separated from a downstream section by a weir, so that a higher static water level is maintained in the inlet section than the downstream section, to facilitate one-way passage of oil/grease from the inlet section to the downstream section. A grinder/pump has an input port in a lower portion of the inlet section. The inlet section has an inlet port, a strainer separating the inlet port and the top of the weir to inhibit passage by solids to the downstream section, and a bottom which slopes downwardly toward the input port of the grinder/pump. An oil/grease separator located in the downstream section removes oil/grease from water held in the downstream section.
