What kind of appearance does good biomass on an RBC typically have?

Good biomass on a rotating biological contactor (RBC) typically has a shaggy and stringy appearance. This texture is indicative of healthy microbial growth, which is crucial for effective wastewater treatment. The shaggy and stringy biomass provides a large surface area for microorganisms to thrive, increasing the efficiency of the treatment process.

This appearance suggests that the biomass is well-established and functioning optimally, as it allows for better adhesion of bacteria and other microorganisms that break down organic matter. A fluffy or soft appearance might not provide the structural integrity needed for efficient biofilm development, while a hard and crusty texture could indicate overgrowth or poor health in the biofilm, leading to reduced treatment efficacy.

Observing the right biomass appearance is critical for operators to assess the health of the system and make any necessary adjustments to ensure that the wastewater treatment process remains effective.
