Thermal Hydrolysis
TRA is moving toward a new way of treating biosolids. Using a phased development process, the solid waste that come from our homes and businesses will be cooked and sterilized using thermal hydrolysis and anaerobic digestion.
This new process will produce a Class A biosolids product, minimizing the amount of biosolids produced and transported, ensuring that throughout the implementation of the new process, there is sufficient overlap for a seamless transition as well as managing and minimizing any odors. The plan for this new process also considers other beneficial reuses for the biosolids, such as composting for commercial buildings.
What is thermal hydrolysis?
It is a process that heats and pressurizes solids. The pressure cooking breaks down the solids and enhances the process of anaerobic digestion.
What is anaerobic digestion?
Anaerobic digestion is a collection of processes by which microorganisms break down biodegradable material in the absence of oxygen. The process is used for industrial or domestic purposes to manage waste and/or to produce fuels. The process produces a biogas, consisting of methane, carbon dioxide and traces of other contaminant gases. Anaerobic digesters are populated with a particular group of microscopic microorganisms that look like mud; it is composed of millions of microorganisms in water.
