Final answer:
True. Inadequate mixing and overfeeding of an anaerobic digester can cause foaming.
Step-by-step explanation:
True. Inadequate mixing and overfeeding can cause foaming in an anaerobic digester.
Anaerobic digestion is a biological process that occurs in an oxygen-free environment, where microorganisms break down organic matter to produce biogas
The digester needs to be well-mixed to ensure proper distribution of nutrients and prevent the formation of foam. Overfeeding can lead to an imbalance in the digestion process, resulting in excessive foam formation.
