majority of restaurants and large scale food production establishments are facing challenges in managing their waste disposal system. The discharge of grease into sewers is causing blockage in pipes and problems at sewage treatment works and septic tanks. Grease is a normal constituent of liquid wastes from kitchens and food preparation rooms where grease is generated from the washing of used crockery and utensils. Facilities must be available at restaurant kitchens for the bulk collection and removal of grease, fats and oil and to prohibit their discharge into the drainage system. The separation and removal of grease substances is possible due to difference in density between the substance to be separated and the carrying liquid and by the reduction of flow velocity.
