The Correlation Parameters for the Construction of Passive Grease Trap for Effective Waste Management

Fat, oil and grease are the three elements usually found in the municipal sewage systems as the results of improper disposal from the sink. These elements come from domestic and commercial kitchens. The absent or inefficient of a plumbing device known as grease trap has caused the trapped of fat, oil and grease in the sewage systems. There are two types of grease trap, namely Passive Grease Trap and Active Grease Trap. These grease types are collected and they can be recycled and used to produce an energy source, for example biodiesel. In Malaysia, the usages of passive grease traps are exercised. There are two parameters that govern the construction of the grease trap, namely retention time and flow rate. The ratio of sizing including the empirical formulations regarding the flow rate and the retention time will be discussed thoroughly in this paper. Furthermore, the understanding of the nature of the fat, oil and grease and the construction guideline for grease trap will be covered in this paper.
