An oil separator (gasoline trap) is designed to prevent and separate oil, wax, and sediment contained in wastewater from parking lots, garages, fueling stations, auto repair shops, and car wash facilities, thereby preventing blockages in drainage systems and hazards such as fires and explosions. The capacity of the oil separator consists of two layers: an oil separation tank necessary for separating water and oil, and a sediment accumulation layer to trap sediment. When selecting an oil separator (gasoline trap), first calculate the maximum inflow rate, oil separation capacity, and sediment accumulation capacity. Then, choose a separator that has an allowable inflow rate, allowable oil separation capacity, and allowable sediment accumulation capacity that exceed the previously calculated values and has a structure that does not hinder functionality. The "Oil Separator (Gasoline Trap) Selection Guide" includes information necessary for selection, such as calculation methods and performance tables for PP-type oil separators. [Contents] - Calculation of maximum inflow rate - Calculation of oil separation capacity - Calculation of sediment accumulation capacity - Calculation examples - Performance table for PP-type oil separators For more details, please contact us or download the catalog.

In the selection of PP-type grease interceptors, if the number of users is known, it is also possible to use a selection method based on the number of users. The inflow flow rate and the mass of the collected grease and accumulated residue are determined using the "method for calculating inflow flow rate" and the "method for calculating the mass of collected grease and accumulated residue." Interceptors are selected that exceed the respective values calculated for the allowable inflow flow rate and the mass of standard collected grease, as indicated by the Air Conditioning and Sanitary Engineering Society standard SHARE-S217-2008. The "Grease Trap (Interceptor) Selection Guide: Selection Method Based on Number of Users" contains necessary information for selection, including these calculation methods and a performance list of grease interceptors. [Contents] - Method for calculating inflow flow rate - Method for calculating the mass of collected grease and accumulated residue - Calculation examples - Performance tables by model and quick reference for number of users For more details, please contact us or download the catalog.

The selection of PP-type grease interceptors generally uses a method based on the total area of the store, including the kitchen. The inflow flow rate and the mass of the collected grease and accumulated residue are determined using the "calculation method for inflow flow rate" and the "calculation method for the mass of collected grease and accumulated residue." Interceptors are selected to exceed the calculated values of the allowable inflow flow rate and the standard mass of collected grease as specified in the Air Conditioning and Sanitary Engineering Society Standard SHARE-S217-2008. The "Grease Trap (Interceptor) Selection Guide: Selection Method Based on Store Area" contains necessary information for selection, including these calculation methods and a performance summary of grease interceptors.
