The recommended tools for performing maintenance on an anaerobic digester are typically made from brass. Brass is particularly valued in this context because it offers a good balance of strength, corrosion resistance, and non-reactivity with the biological processes occurring within the digester. Since anaerobic digesters operate under conditions of high moisture and the presence of various gases, tools made from materials that resist corrosion and contamination are essential for ensuring the integrity of the facility and the safety of maintenance personnel.

Brass tools help to minimize the risk of rust and degradation, which can occur with steel tools over time, especially in the damp and nutrient-rich environment of an anaerobic digester. Additionally, brass is less likely to react with the various compounds found in the digestate, thus preventing any adverse effects on the digestion process itself.

Other materials, such as plastic and aluminum, may not provide the necessary durability or corrosion resistance for long-term use in such demanding environments. Plastics could wear down or deform under stress, while aluminum might be susceptible to corrosion in the presence of certain chemicals inherent in the wastewater treatment process. Consequently, brass emerges as the most suitable material for maintaining the functionality and safety of anaerobic digesters.
