Which type of grease trap is considered the most effective for removing grease from kitchen waste?

A baffle grease trap is considered the most effective for removing grease from kitchen waste due to its design, which enhances the separation of grease from wastewater. The baffle system allows wastewater to enter the trap and flow through a series of baffles or barriers that create defined flow paths. This structure facilitates the settling of solids at the bottom while trapping grease at the top, preventing it from escaping with the liquid.

The effectiveness of a baffle grease trap lies in its ability to slow down the flow of water, enabling more grease to float and form a layer on top. As grease accumulates, it is kept separate from the wastewater, thereby allowing for better management of grease loads that would otherwise lead to clogs in plumbing systems.

The other options, while they perform functions related to grease removal, do not provide the same level of efficiency in separating and retaining grease. Gravity grease traps rely on the difference in density between grease and water but may not effectively trap grease if the flow is too fast. Hydraulic grease traps are designed to manage high volumes of wastewater but may not necessarily focus on maximizing grease removal. Stringent grease traps, while they imply a stricter filtration process, do not refer to a specific type of trap used widely in the industry.
