Biogas Treatment – Siloxanes Removal in Municipal WWTP – Case Study

A case study from a municipal wastewater treatment plant regarding the management of siloxanes, which are silica-based organic compounds found in consumer goods that contaminate biogas systems. These substances are problematic because they create a harmful fouling layer on machinery, leading to the rapid deterioration of essential engine components like spark plugs and pistons. To combat this, the text introduces a stainless steel reactor that utilises doped activated carbon to adsorb these impurities with high efficiency. The data confirms that implementing this reactor significantly lowers silicone concentrations in lubricant oil, thereby extending the operational lifespan and maintenance intervals of the power generation equipment.
