A TOUR OF SLUDGE TREATMENT INNOVATION

June 15, 2010

I recently had the opportunity to join PC Construction Senior Estimator Andy Seaton on a trip to England and Ireland to tour several facilities and learn about a new sludge treatment process being used in Europe and that is expected to be introduced in the United States soon. A Norwegian company, Cambi, developed a Thermal Hydrolysis Process (THP) that takes primary sludge and heats it to approximately 165 degrees Celsius (330 degrees Fahrenheit), resulting in hydrolysed sludge. This process kills all of the pathogens that are found in sludge which makes it suitable for creating a Class “A” Sludge that can be land applied as a commercially saleable fertilizer. It also increases the amount of Volatile Organic Compounds that are released during the digestion process (which increases the amount of biogas that can be produced and used to generate electricity and steam that is used in the THP –while reducing the amount of sludge to be handled) and reduces the mesophilic digestion time (which reduces the size of the anaerobic digesters from those that would be required in a conventional process).  Utilization of this process has gradually increased in Europe as many of the technical issues associated with the extreme heat, pressure and caustic environment that are created in the process have been resolved. Engineers are now beginning to recommend the use of the THP at U.S. facilities.
