What is the main purpose of a baffle board in a septic system?

A baffle board plays a crucial role in a septic system by helping to reduce the agitation of scum that forms at the surface of the septic tank. The baffle prevents the scum from being disturbed, which helps maintain the separation between the different layers of waste in the tank. This separation is vital because it allows solids to settle at the bottom while lighter materials, like oils and grease, float on top as scum.

By minimizing the agitation of scum, the baffle ensures that the tank operates efficiently and prevents the mixing of these layers, which can lead to issues with the system, such as clogging or inefficient waste processing. This function is essential for the longevity and effectiveness of the septic system as it aids in the proper breakdown of organic matter and allows for better treatment of wastewater before it is released into the drainage field.
