The merchandise under consideration is described as the Rhino Wet Waste Interceptor Filtration System, which will be used in the food service industry to capture fats, oils, and grease from wastewater before entering the grease trap and flowing into municipal drains. In operation, the Rhino Wet Waste Interceptor Filtration System will be connected to the drain, allowing water and wet waste to enter the unit, where it will then pass through the filter, trapping the wet waste. Liquids that are free from wet waste are then able to pass through the unit where they are directed to the grease trap.
