Abstract
A separator and method of its use for separating oil, grease F.O.G. from effluent has a control to avoid potential user errors. A skimming control causes skimming events to occur in accordance with presets that include a preset minimum skim setting above zero, a preset maximum skim setting below a continuous skim event. A user interface allows the user to select a user skim mode. The user skim mode settings include a programming cycle that directs a series of skimming events to occur at substantially non-repetitive times during a skimming event cycle.
Claims32
A separator assembly for separating fat, oil, and grease from effluent comprising:
- a container with a cover for receiving and holding effluent water containing oil, grease and solid waste to be removed from the effluent water;
- at least one rotatable disk supported within the container in a partially immersed position within the body of effluent water and in contact with the oil and grease;
- a drive mounted in driving engagement to provide rotation of the disk when the drive is engaged;
- a trough mounted in engaging relation to opposite sides of the rotatable disk;
- a scraper blade mounted on the trough so that the scraper blade extends from the trough into sliding engagement with a side of the disk, the disk, scraper blade and trough cooperatively disposed and structured to direct oil and grease from the disk along the scraper blade along the trough for collection in a storage container;
- a skimming control that controls when the drive activates rotation of the disk to skim F.O.G. from the effluent, the skimming control having:
- a preset minimum skim setting above zero,
- a preset maximum skim setting below a continuous rotation of the disk, and
- a user interface that allows the user to select a user skim mode setting between the preset minimum skim setting and the preset maximum skim setting.
6 more elements
A skimmer control system for a F.O.G. separator that removes F.O.G. from effluent, comprising:
- a skimming control that controls when a skimming event occurs to skim F.O.G. from the effluent, the skimming control having:
- a preset minimum skim setting above zero,
- a preset maximum skim setting below a continuous skim event, and
- a user interface that allows the user to select a user skim mode setting between the preset minimum skim setting and the preset maximum skim setting,
- wherein the user skim mode settings include a programming cycle that directs a series of skimming events to occur at substantially non-repetitive times during a skimming event cycle.
2 more elements
A method of controlling removal of grease, oil and solid waste material from effluent water comprising:
- installing an oil, grease and solid waste removal assembly at a facility site;
- connecting an inlet pipe of the oil, grease and solid waste removal assembly to a source discharging effluent water with waste materials to be removed;
- connecting an outlet pipe of the oil, grease assembly to a sewage system;
- installing an oil and grease storage container to receive oil and grease flow from a trough in the assembly;
- engaging a drive motor of the assembly to rotate a disk in the assembly to remove oil and grease from effluent water;
- controlling the drive motor with a skimming control that controls when the drive activates rotation of the disk to skim F.O.G. from the effluent, the skimming control having:
- a preset minimum skim setting above zero,
- a preset maximum skim setting below a continuous rotation of the disk, and
- a user interface that allows the user to select a skim mode setting between the preset minimum skim setting and the preset maximum skim setting.
6 more elements
A method of making a F.O.G. removal assembly comprising:
- rotomolding a container having inlet and outlet ends, a strainer basket support, an outlet baffle and a cover for the container,
- securing the strainer basket support within the container,
- securing the outlet baffle within the outlet end of the container,
- installing a F.O.G. removal skimmer assembly that has a rotatable disk and a drive to provide rotation of the disk when the drive is engaged and a skimming control that controls when the drive activates rotation of the disk to skim F.O.G. from the effluent, the skimming control having:
- a preset minimum skim setting above zero,
- a preset maximum skim setting below a continuous rotation of the disk, and
- a user interface that allows the user to select a skim mode setting between the preset minimum skim setting and the preset maximum skim setting.
4 more elements
A method of controlling a skimming event for a F.O.G. separator that removes F.O.G. from effluent, comprising:
- programming a skimming control that controls when a skimming event occurs to skim F.O.G. from the effluent, the skimming control having a preset minimum skim setting above zero in the control and a preset maximum skim setting below a continuous skim event in the control, and
- providing a user interface that allows the user to select a user skim mode setting between the preset minimum skim setting and the preset maximum skim setting, wherein the user skim mode settings include a programming cycle that directs a series of skimming events to occur at substantially non-repetitive times during a skimming event cycle.
A separator assembly for separating fat, oil, and grease (F.O.G.) from effluent comprising:
- a container for receiving and holding effluent water containing F.O.G. to be removed from the effluent water;
- a skimmer within the container in a partially immersed position within the body of effluent water and in contact with the F.O.G. and configured to remove F.O.G and direct it to a storage container;
- a skimming control that controls when the skimmer is active, the skimming control having:
- a preset minimum skim setting above zero,
- a preset maximum skim setting below a continuous rotation of the disk, and
- a user interface that allows the user to select a skim mode setting between the preset minimum skim setting and the preset maximum skim setting.
