Abstract: A separator assembly for separating fat, oil, and grease from effluent includes a container for receiving and holding effluent water containing oil, grease and solid waste to be removed from the effluent water and a communications module having a processor, memory and transmitter at the facility site to communicate over cellular or WiFi signals with a remote station. The separator may include a skimmer to skim F.O.G. from the effluent water held in the container or be of a grease trap mode collecting F.O.G. for subsequent removal.

Abstract: A container for receiving and holding effluent water containing oil/grease to be removed including a sealed enclosure. In one example, a cover supports a partially immersed rotatable disk; a drive on the main sectional cover rotates the disk; a trough on the main sectional cover straddles the disk; and a blade on the trough scrapes a side of the disk, to direct oil and grease from the disk along the scraper blade along the trough for collection in a storage container. Efficiencies of construction of the sectional covers, disk and a sensor probe are disclosed in some examples. Also disclosed are apparatus, system and methods for a sealed container for receiving and holding effluent water containing oil/grease to be removed.

Abstract: An apparatus having a layer of fats, oils and grease (F.O.G) on water includes a tank having an inlet and an outlet. The inlet connects to a source of F.O.G.-laden effluent and the outlet connects to a sewer pipe so that the outlet defines a normal static water level for F.O.G. and effluent in the tank. A sensor mounted above the static water level determines a distance from the sensor to a top of F.O.G. within the tank, so that a thickness of the F.O.G. in the tank can be determined. If the sensor is LIDAR, sensing may be at about 940 nm. When the F.O.G. is sensed to be above a threshold, the apparatus generates signals to remove the F.O.G. Ultrasonic sensing may be used. Preferably, the sensor is mounted far enough above the static water level so the distance between the sensor and the liquid surface is filled with air. More preferably, the sensor is far enough above the static water level so that the top of the F.O.G. does not touch the sensor even as the top of the F.O.G.

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.
